How to Prepare an ADA Sign RFQ: What Should You Include for an Accurate Quote?

An ADA sign RFQ is not just a request for prices. It is the document that decides whether three manufacturers are pricing the same signage package or three different interpretations of it. A request such as “500 ADA signs, please quote” may look complete until one factory assumes single-layer acrylic, another includes tactile characters and Braille, and a third excludes mounting hardware, individual labeling, and floor-by-floor packing. The price difference may appear to be 15% or 20%, while the real difference is hidden in scope. ADA signage makes the problem even more serious because room identification, directional signs, pictograms, tactile characters, Braille, contrast, mounting locations, and local project requirements do not all follow one identical rule. A reliable RFQ therefore has to control both commercial information and manufacturing information before unit prices become meaningful. The more clearly the sign schedule, approved drawings, quantities, messages, materials, mounting, samples, packaging, and delivery conditions are defined, the fewer surprises appear after a quotation turns into a production order.

A strong ADA sign RFQ should include the project location, approved sign schedule, sign types, exact messages, quantities, dimensions, tactile and Braille requirements, materials, finishes, mounting details, wall conditions, sample requirements, packaging instructions, delivery destination, and required date. Every quotation should reference the same drawing and schedule revision so materials, scope, exclusions, lead time, and landed cost can be compared accurately.

Imagine a 12-story hotel requesting prices for 680 signs. One quotation comes back at $11,800, another at $14,200, and a third at $16,000. The cheapest offer looks obvious—until the project team discovers it covers 42 fewer signs, uses a different panel construction, excludes the approved sample, provides no mounting hardware, packs all room signs in bulk, and prices freight separately. By the time those gaps are added back, the “cheapest” offer is no longer the lowest. The sections below show how to build the RFQ so those differences are visible before a purchase order is issued, not after signs are already in production.

What Should an ADA Sign RFQ Include?

An ADA sign RFQ should define the project location, sign schedule, sign types, exact messages, dimensions, quantities, tactile and Braille requirements, materials, finishes, mounting, packaging, sample requirements, and delivery date. The goal is to remove assumptions before pricing so every manufacturer quotes the same scope and any later price change can be traced to a documented specification revision.

What Project Information Should You Provide?

Start the RFQ with enough project context for the manufacturer to understand where the signs will be used, how the order will be organized, and which requirements control production.

At minimum, provide:

• Project name
• Project type
• Building location
• City and state
• Destination country
• Number of buildings
• Number of floors
• New construction or renovation
• Estimated total sign quantity
• Required sample date
• Required production completion date
• Required delivery date
• Shipping address
• Installation responsibility
• Drawing approval contact
• ADA or accessibility approval contact
• Architect or contractor contact when applicable

Project type should be specific. “Commercial building” is less useful than “12-story office building,” “180-room hotel,” “outpatient medical center,” or “three-building apartment development.”

The difference directly affects how the sign package is organized.

A hotel RFQ may contain:

Sign Group	Typical Examples	Main RFQ Concern
Guest rooms	Room numbers, accessible rooms	Hundreds of unique messages
Public areas	Restrooms, meeting rooms	Tactile/Braille and pictograms
Service areas	Electrical, mechanical, housekeeping	Correct room identification
Vertical circulation	Stair and floor signs	Floor-specific content
Wayfinding	Directional signs	Arrow direction and message accuracy
Back-of-house	Staff rooms, storage, utilities	Large quantity of unique text

A 200-room hotel therefore should not be introduced as only “200 room signs.” The full package may contain several hundred additional identification, regulatory, stair, restroom, service, and directional signs.

The project location should also appear near the top of the RFQ.

Avoid writing only:

“Need ADA-compliant signs.”

A stronger instruction is:

“Project location: Austin, Texas, USA. Manufacture according to the approved architectural signage drawings and accessibility specifications issued for the project.”

Location matters because the manufacturing team needs to know which approved project documents govern the order. Final interpretation of local accessibility requirements, approved wording, mounting position, mounting height, and site acceptance should remain with the architect, accessibility consultant, contractor, or local authority rather than being left for the factory to determine. iduoduo follows the same project boundary when manufacturing ADA and architectural signs.

For renovation work, add another group of information:

• Existing sign size
• Existing mounting method
• Existing hole locations
• Wall material
• Whether drilling is permitted
• Whether old holes must be covered
• Whether the new sign must match an existing system
• Whether previous colors must be reproduced
• Whether replacement signs must fit an existing insert holder or frame

Those details often affect cost more than the room number printed on the face.

Which Drawings and Files Should You Send?

Send every file that controls what will be manufactured, but clearly identify which version is current.

The strongest RFQ package normally includes:

• Sign schedule
• Architectural signage drawings
• Floor plans
• Room schedule
• Sign-location plans
• Elevations
• Sign-type details
• Artwork
• Brand guidelines
• Color schedule
• Finish schedule
• Material specifications
• Mounting details
• Accessibility details
• Approved pictograms
• Packing instructions
• Project revision log

Whenever possible, provide production-useful formats such as:

• PDF
• AI
• SVG
• EPS
• DWG
• DXF

JPG and PNG files can still help explain the intended appearance, but they should not become the only production reference when exact dimensions, text spacing, pictograms, or vector artwork are available elsewhere.

For example, a room sign may appear simple in a JPG rendering, but quotation still depends on information such as:

Item	Drawing Should Confirm
Overall size	Width × height
Panel thickness	Single or layered construction
Text	Exact wording
Tactile text	Size, location, spacing
Braille	Approved content and position
Pictogram	Artwork and field size
Finish	Matte, painted, printed, brushed, etc.
Color	Pantone, RAL or approved reference
Mounting	Adhesive, studs, screws or other method

Floor plans are particularly important for directional signs.

A spreadsheet may say:

“ROOMS 201–220”

but the floor plan determines whether the arrow points left, right, straight ahead, or in another direction.

The room schedule is equally important because it may reveal late room-name changes that have not yet reached the signage drawings.

The safest approach is to establish one document hierarchy.

For example:

1. Approved sign schedule controls messages and quantities.
2. Sign-type drawings control construction and dimensions.
3. Floor plans control locations and directions.
4. Brand standards control approved colors and graphics.
5. Latest written revision notice controls approved changes after issue.

Version control should be visible.

Avoid filenames such as:

Final Signs.xlsx
Final Signs New.xlsx
Final Signs Updated.xlsx
Final Signs New Final.xlsx

Use a controlled naming system instead:

ADA-Sign-Schedule-Rev-A
ADA-Sign-Schedule-Rev-B
ADA-Sign-Schedule-Rev-C

Then write directly in the RFQ:

“Quotation shall be based on ADA Sign Schedule Rev C dated August 18, 2026.”

Ask the manufacturer to repeat the same revision number on the quotation.

That single practice makes later price comparisons much easier. If the project moves from 486 signs in Rev C to 512 signs in Rev D, the commercial change can be traced to a specific revision rather than debated through old email attachments.

iduoduo’s production workflow is built around converting approved logos, drawings, architectural files, brand standards, measurements, and installation requirements into controlled production files, shop drawings, mounting details, finish schedules, and approved manufacturing versions.

What Sign Types and Quantities Should Be Listed?

List quantities by sign code and construction, not only by total project quantity.

A request reading:

“500 ADA signs”

does not give enough information for accurate production pricing.

Those 500 pieces may actually consist of:

Sign Code	Sign Type	Quantity	Unique Messages	Tactile/Braille
R-01	Guest Room ID	286	286	Yes
R-02	Accessible Room ID	24	24	Yes
RR-01	Restroom Sign	18	4	Yes
ST-01	Stair Identification	32	16	Per approved detail
F-01	Floor Identification	12	12	Yes
D-01	Directional Sign	46	28	No
S-01	Service Room Sign	63	51	Yes
O-01	Office Sign	19	14	Depends on room use

Total quantity: 500 pieces.

But commercially and operationally, those 500 signs are not one product.

The RFQ should ideally state five numbers:

• Total signs
• Total sign types
• Total unique messages
• Total floors or areas
• Total delivery phases

For example:

Total signs: 684
Sign types: 14
Unique messages: 527
Floors: 21
Delivery phases: 2

That tells the factory much more than “684 pcs.”

Unique-message quantity matters because ADA projects frequently involve repetitive construction but non-repetitive content.

Producing 300 identical promotional panels is not the same as producing 300 room signs where every room number and corresponding Braille message must be checked separately.

A large room-identification package may require individual checking of:

• Visible room number
• Room name
• Tactile text
• Braille
• Pictogram
• Sign code
• Floor
• Building
• Package group

iduoduo’s ADA and architectural-sign workflow uses sign schedules, unique sign codes, tactile and Braille specifications, item-by-item content inspection, and floor- or area-based packing.

The schedule should also distinguish permanent identification signs from directional and informational signs rather than assuming every sign follows the same construction.

A useful schedule can include columns such as:

Field	Example
Sign Code	R-101
Building	Tower A
Floor	08
Room	0812
Sign Type	Room Identification
Message	812
Quantity	1
Tactile	Yes
Braille	Yes
Pictogram	No
Size	8 × 8 in.
Finish	Matte Black
Mounting	VHB + silicone
Package	Floor 08

This structure helps quotation, artwork preparation, production, QC, packing, and installation all work from the same data.

How Detailed Should the RFQ Be?

The RFQ should be detailed enough to prevent manufacturers from filling important gaps with different assumptions, but it should not invent technical specifications that have not actually been approved.

A practical approach is to classify every important specification as:

Status	Meaning	Example
Fixed	Must follow project documents	Size: 8 × 8 in.
Manufacturer Recommendation	Factory may propose a solution	Panel thickness
Pending Approval	Project team has not finalized it	Final gray Pantone
Optional	Quote separately	Individual floor packing

That makes uncertainty visible.

For example, the following line is too vague:

“Custom acrylic Braille room sign, 300 pcs.”

A more quote-ready line is:

“R-01 guest-room identification sign, 8 × 8 in., matte acrylic construction, raised room number, Grade 2 Braille per approved schedule, dark background with light characters, adhesive mounting to painted drywall, individual room-number labeling, packed by floor, 286 pcs.”

The second version answers most of the questions that otherwise generate a second quotation.

For each sign type, try to define:

• Sign code
• Sign function
• Exact dimensions
• Quantity
• Number of unique messages
• Visible text
• Tactile requirement
• Braille requirement
• Braille approval source
• Pictogram requirement
• Material
• Thickness
• Surface finish
• Color
• Edge treatment
• Mounting method
• Wall substrate
• Hardware included or excluded
• Individual label requirement
• Packing method
• Sample requirement
• Delivery phase

Not every field needs to be fixed before the first budget quote.

The important point is to distinguish “unknown” from “manufacturer assumption.”

For example:

Material: manufacturer to recommend
Color: Pantone 432 C
Mounting: adhesive, final tape system to be recommended
Braille wording: project team to approve
Packing: quote standard bulk packing and floor-sorted packing separately

Now every factory knows where it has freedom and where it does not.

Ask suppliers to write assumptions directly into the quotation.

A useful RFQ instruction is:

“Please list all assumptions and exclusions related to materials, Braille, tactile characters, mounting hardware, samples, packing, freight, production lead time, and delivery.”

Without that instruction, one factory may include mounting hardware and another may exclude it. One may include floor-by-floor packing while another quotes bulk cartons. One may calculate a pre-production sample while another assumes direct mass production.

The unit prices may look comparable even though the scopes are not.

Before releasing the RFQ, run one final check:

• Project location confirmed
• Current sign schedule attached
• Current drawing revision attached
• Sign codes match drawings
• Quantities match schedule
• Unique messages identified
• Room numbers checked
• Sign functions identified
• Tactile requirements identified
• Braille responsibility confirmed
• Material status defined
• Finish status defined
• Color references provided
• Mounting method identified
• Wall substrate identified
• Sample requirement identified
• Packing requirement identified
• Required delivery date confirmed
• Shipping destination confirmed
• Approval contact identified
• Quote assumptions requested

The objective is not to produce the longest RFQ. The objective is to make it difficult for two manufacturers to quote two different interpretations of the same project.

When the RFQ contains controlled drawings, clear sign codes, accurate quantities, unique message counts, mounting conditions, packaging requirements, and a defined approval path, the quotation becomes a useful project number rather than an early estimate that changes repeatedly after engineering review.

Which ADA Requirements Must Be Defined?

An ADA sign RFQ should identify which signs require tactile characters, Braille, visual characters, pictograms, accessibility symbols, and controlled mounting locations. It should also reference the approved project accessibility standard. Sign function matters: permanent room identification, directional signage, exit-door identification, and informational signs do not automatically follow the same requirements under the federal ADA Standards.

Which Signs Need Tactile Characters and Braille?

Do not mark every line in a sign schedule simply as “ADA.”

First classify what the sign actually does.

Under the federal ADA Standards, signs identifying permanent rooms and spaces generally must meet tactile and visual requirements. The U.S. Access Board gives room and floor numbers, room names, restrooms, locker rooms, cafeterias, libraries, conference rooms, and mechanical rooms as examples of permanent-room or permanent-space designations. Directional and informational signs generally need visual compliance but are not automatically required to carry tactile characters and Braille.

That distinction should appear directly in the sign schedule.

Sign Function	Typical Example	Federal ADA Treatment to Check
Permanent room ID	ROOM 214	Tactile + visual
Permanent room name	ELECTRICAL ROOM	Tactile + visual
Restroom identification	WOMEN / MEN / ALL GENDER	Tactile + visual
Floor identification	LEVEL 4	Tactile + visual where used as permanent designation
Directional	ELEVATORS →	Visual
Informational	VISITORS MUST SIGN IN	Visual
Exit stairway door ID	EXIT / STAIR designation	Tactile + visual where required
Building directory	Tenant listing	Generally exempt from §216
Occupant name	DR. SMITH	Generally exempt from §216
Company name or logo	ABC CORPORATION	Generally exempt from §216
Temporary sign	Construction notice ≤7 days	Generally exempt from §216

The exemptions are easy to miss. Federal Section 216 states that building directories, menus, seat and row designations, occupant names, building addresses, company names and logos, and temporary signs lasting seven days or less are not required to comply with the general sign provisions of Section 216.

For quotation purposes, add an accessibility classification column rather than asking the factory to infer requirements from the message.

A working sign schedule could use:

Sign Code	Message	Function	Tactile	Braille	Visual
R-101	101	Permanent Room ID	Yes	Yes	Yes
RR-01	RESTROOM	Permanent Room ID	Yes	Yes	Yes
D-04	ROOMS 201–220 →	Directional	No	No	Yes
I-03	VISITORS MUST SIGN IN	Informational	No	No	Yes
ST-02	STAIR B	Stair Identification	Per approved detail	Per approved detail	Yes

That structure does three things at once: it gives procurement a measurable quantity, gives engineering a technical classification, and gives QC a sign-by-sign inspection requirement.

It also prevents unnecessary cost. Adding tactile characters and Braille to every directional sign may increase fabrication and inspection work without being required by the federal ADA rule. Removing them from permanent-room identification creates the opposite risk.

Pictograms need the same functional review. When a pictogram identifies a permanent room or space, federal rules require the applicable pictogram treatment and a tactile text descriptor. A purely informational pictogram or accessibility symbol follows a different rule set.

The RFQ should therefore never rely on a single column reading “ADA: Yes/No.” A sign-function column plus separate tactile, Braille, visual, and pictogram columns creates a much safer production document.

What Tactile and Braille Details Should Be Specified?

Writing “raised letters + Braille” is not enough for production.

The RFQ should define the approved tactile text, Braille content, character dimensions, font family, spacing, Braille position, pictogram relationship, and any sign-border conditions. When project drawings already provide those values, the manufacturer should quote against the drawing rather than substitute a house standard.

For the federal ADA Standards, several measurable controls are especially important:

Requirement	Federal ADA Reference Point
Raised character depth	1/32 in. minimum
Raised character case	Uppercase
Raised character style	Sans serif
Raised character height	Generally 5/8–2 in. when also serving as visual characters
Stroke thickness	15% maximum of uppercase “I” height
Character proportion	“O” width 55–110% of “I” height
Line spacing	135–170% of character height
Braille	Contracted / Grade 2
Braille position	Below corresponding raised text
Text-to-Braille separation	3/8 in. minimum
Braille-to-raised border separation	3/8 in. minimum

The Access Board also specifies that Braille dots are domed or rounded rather than flat or sharply formed.

Those dimensions matter in real production.

Consider a sign reading:

MECHANICAL
ROOM
B214

The designer cannot simply shrink the lettering until everything fits a small panel. Character height, stroke width, spacing between characters, line spacing, Braille position, and edge clearances consume physical area. A panel that looks spacious on a screen may become crowded once tactile geometry and Braille are built correctly.

Long messages should therefore be reviewed before quotation.

Useful RFQ fields include:

• Approved visible message
• Approved tactile message
• Approved Braille translation
• Raised character height
• Font
• Character layout
• Number of text lines
• Braille line count
• Pictogram
• Sign dimensions
• Border or decorative elements
• Sign code
• Revision number

Braille translation responsibility needs to be explicit.

Do not allow an order to reach production with three conflicting text sources:

Architectural drawing: ELECTRIC ROOM
Room schedule: ELECTRICAL ROOM
Email revision: ELEC. ROOM

The factory should not decide which wording becomes the permanent tactile message.

A better sign schedule provides one approved production field:

Visible/Tactile Text: ELECTRICAL ROOM
Braille: Approved per Rev C
Room: B214
Sign Code: R-07
Approval Status: Approved for Production

The same rule applies to capitalization. Raised tactile characters under the federal standard are uppercase, while Braille capitalization follows Braille conventions rather than simply reproducing every visual capital letter mechanically.

Large projects also need content-level QC.

For a 600-piece room identification order containing 520 unique messages, checking only overall panel dimensions is inadequate. Inspection should verify each sign code against the approved schedule:

QC Check	Example
Sign code	R-B214
Visible message	ELECTRICAL ROOM
Tactile message	ELECTRICAL ROOM
Braille	Matches approved content
Room number	B214
Pictogram	Correct / N/A
Finish	Approved sample
Mounting	Correct hardware
Packing group	Building B / Level 2

iduoduo’s documented architectural-sign process follows approved sign schedules, tactile and Braille specifications, unique sign codes, and item-by-item content inspection rather than treating a batch of room signs as identical generic plaques.

How Should Contrast and Finish Be Defined?

Specify actual foreground and background finishes instead of writing only “ADA contrast.”

Under the federal ADA Standards, visual characters and their backgrounds must use a non-glare finish and provide either light characters on a dark background or dark characters on a light background. The federal standard does not prescribe a single minimum numerical contrast ratio for these signs, so “high contrast” should not be replaced by an invented universal percentage.

For an RFQ, define color and finish separately.

Specification	Weak RFQ Wording	Better RFQ Wording
Background color	Dark gray	Pantone 432 C
Character color	White	Approved warm white sample
Finish	ADA finish	Matte, non-glare
Surface	Acrylic	Painted acrylic, matte
Contrast	High contrast	Light characters on dark approved background
Batch control	Match color	Match approved sample / Rev B finish schedule

Finish matters because two materials with almost identical colors can behave differently under overhead lighting.

A polished or highly reflective face may create glare. A matte or low-gloss face generally reduces reflections and can make characters easier to locate visually, but the actual project finish still needs approval.

Do not assume Braille dots need a contrasting color. The Access Board guidance notes that finish and contrast requirements applying to visual characters do not apply to Braille.

Pictograms also need careful treatment.

When a pictogram is used to identify a permanent room or space, federal guidance calls for the pictogram to meet applicable finish and contrast criteria and to appear within a field at least 6 inches high, together with the required tactile text descriptor. Informational pictograms and pictograms on directional signs do not automatically carry the same 6-inch field and tactile-descriptor requirements.

That difference can change the physical size of a restroom or stair sign.

For example, a design team may initially propose a 5 × 7 inch panel containing:

• large restroom pictogram
• raised text
• Braille
• decorative border

After the required pictogram field, tactile text, Braille spacing, and border clearance are applied, the available panel area may no longer be sufficient.

A manufacturability check before bulk pricing is therefore useful.

For branded architectural projects, the RFQ should define:

Item	Recommended Control
Background	Pantone/RAL/approved physical sample
Characters	Pantone/RAL/approved physical sample
Finish	Matte, satin, brushed, printed, painted
Pictogram	Approved vector artwork
Metal accent	Brushed direction or coating
Printed graphics	Approved CMYK/Pantone reference
Sample	Physical color/finish sample where critical
Repeat production	Retain approved reference and reconfirm batch

Color names such as “charcoal,” “warm gray,” “off-white,” or “champagne” are not precise enough for a multi-floor project.

A procurement team ordering 800 signs across three phases needs a documented color reference, approved sample, and finish specification if later replacement signs are expected to remain visually consistent.

Who Is Responsible for Final ADA Approval?

The RFQ should name the person or organization responsible for final accessibility interpretation and production approval. A sign manufacturer can manufacture to approved drawings, review fabrication feasibility, produce tactile characters and Braille, prepare samples, and flag obvious conflicts, but the factory should not silently become the architect, accessibility consultant, code official, or authority having jurisdiction.

A practical responsibility matrix prevents expensive arguments later.

Task	Typical Responsible Party
Determine applicable federal/state/local requirements	Architect / accessibility consultant / code professional
Classify permanent vs. directional signs	Project design team
Approve room names and numbers	Architect / facility/project team
Approve Braille wording	Design/accessibility authority
Approve pictograms	Architect / brand/accessibility team
Approve mounting location	Architect / contractor / accessibility consultant
Approve mounting height	Architect / accessibility consultant
Confirm wall conditions	Contractor / installer
Review manufacturability	Sign manufacturer
Prepare production drawings	Sign manufacturer
Produce tactile characters and Braille	Sign manufacturer
Check signs against approved schedule	Sign manufacturer
Approve production sample	Authorized project representative
Final site inspection	Local project authority / responsible professional

The distinction becomes especially important with tactile mounting.

Federal ADA guidance generally places tactile character baselines between 48 and 60 inches above the finished floor or ground. Door-side location also depends on door configuration. For example, tactile signs are generally located on the latch side of a single door; special rules apply to double doors, doors with no wall space, glass sidelights, and certain doors where a sign may be placed on the push side.

Those conditions cannot always be determined from a factory in another country.

A drawing may show:

“Mount sign beside door.”

The site may actually contain:

• full-height glass on the latch side
• a 6-inch-wide wall return
• double active door leaves
• a fire door with specific hardware
• a wall-mounted device occupying the intended location
• a door swing entering the tactile approach area

The local project team should therefore approve the final installation location.

The RFQ should clearly state the approval path.

For example:

“Manufacturer shall fabricate according to the approved sign schedule, accessibility details, artwork, material schedule, and mounting drawings. Final code interpretation, text approval, Braille approval, installation location, mounting height, and local compliance approval remain with the project architect, accessibility consultant, contractor, or authority having jurisdiction.”

That wording is consistent with iduoduo’s documented ADA manufacturing boundary: the factory can follow approved drawings, project standards, tactile and Braille specifications, materials, sign codes, mounting details, and packing instructions, while final regulatory interpretation and local site approval remain with the responsible project professionals.

Before production release, the approval record should ideally show:

Approval Item	Status
Sign schedule	Approved
Sign-type drawings	Approved
Visible messages	Approved
Tactile messages	Approved
Braille	Approved
Pictograms	Approved
Colors	Approved
Finish	Approved
Materials	Approved
Mounting details	Approved
Sample	Approved if required
Revision	Frozen for production

The aim is not to push responsibility away from the manufacturer. It is to assign each decision to the party with the information and authority to make it.

The manufacturer should own manufacturing accuracy against the approved production package. The local design and construction team should own the project-specific compliance decisions that depend on applicable regulations, building conditions, and site installation.

Which ADA Requirements Must Be Defined?

An ADA sign RFQ should define each sign’s function, tactile status, Braille requirement, visual-character requirements, pictograms, approved text, finish, contrast, and mounting criteria. Permanent room identification, directional signs, informational signs, and accessibility symbols can follow different federal ADA provisions, so the RFQ should classify requirements sign by sign rather than labeling the entire package simply “ADA compliant.”

Which Signs Need Tactile Characters and Braille?

The first job is not choosing acrylic thickness or Braille production method. It is deciding what each sign actually does.

Under the federal ADA Standards, signs identifying permanent rooms and spaces, where provided, generally need both tactile and visual treatment. Examples include room numbers, floor numbers, restroom identification, conference rooms, mechanical rooms, cafeterias, libraries, and other permanent room or space designations. Required door labels at exit stairways, exit passageways, and exit discharge also have tactile requirements.

Directional and informational signs are different. Signs such as “ELEVATORS →,” “ROOMS 201–220 →,” operating instructions, rules, or hours of operation generally need to meet visual-character requirements but are not automatically required to carry raised characters and Braille.

For an RFQ, classify each sign before sending quantities to a manufacturer.

Sign Example	Main Function	Tactile	Braille	Visual
ROOM 214	Permanent room ID	Yes	Yes	Yes
ELECTRICAL ROOM	Permanent room ID	Yes	Yes	Yes
WOMEN RESTROOM	Permanent room ID	Yes	Yes	Yes
CONFERENCE ROOM A	Permanent room ID	Yes	Yes	Yes
STAIR B	Permanent designation / project detail	Check approved detail	Check approved detail	Yes
ROOMS 201–220 →	Directional	No	No	Yes
ELEVATOR →	Directional	No	No	Yes
VISITORS CHECK IN HERE	Informational	No	No	Yes
HOURS 8:00–5:00	Informational	No	No	Yes
JOHN SMITH, DIRECTOR	Occupant name	Generally exempt	Generally exempt	Generally exempt
ABC CORPORATION	Company name/logo	Generally exempt	Generally exempt	Generally exempt

The federal guide also identifies several sign categories that are exempt from the general visual and tactile requirements, including temporary signs posted for seven days or less, building addresses and directories, occupant names, company names and logos, menus, and seat or row designations in assembly areas.

The exemption matters in real projects.

Consider an office identification sign containing:

403
ACCOUNTING
JILL SMITH
DIRECTOR

Those four lines do not necessarily have the same accessibility treatment.

The permanent room number may need tactile and visual treatment. “ACCOUNTING” may function as informational content depending on how the room is designated. “JILL SMITH” and “DIRECTOR” are occupant-related information and may be exempt. One plaque can therefore contain tactile, visual-only, and exempt information at the same time. The Access Board specifically notes that different content on one sign can be subject to different requirements.

That is why a single spreadsheet column reading “ADA = YES” is too crude for a serious sign package.

Use separate columns:

Sign Code	Function	Raised Text	Braille	Visual Text	Pictogram	Approval Status
R-214	Permanent Room ID	Yes	Yes	Yes	No	Approved
RR-03	Restroom	Yes	Yes	Yes	Yes	Approved
D-17	Directional	No	No	Yes	No	Approved
O-09	Office ID	Per approved use	Per approved use	Yes	No	Pending
DIR-01	Directory	No	No	Project standard	No	Approved

Pictograms also need classification.

When a pictogram identifies a permanent room or space—such as a restroom, stairway, or cafeteria—the federal ADA guide requires a tactile text descriptor below the pictogram field, and the pictogram field itself must be at least 6 inches high. The pictogram itself does not have to be raised. Informational pictograms and pictograms used on directional signs do not automatically require the same 6-inch field or tactile descriptor.

That detail can change a sign dramatically.

A 5 × 7 inch restroom concept may look acceptable in a rendering. Once a 6-inch pictogram field, tactile text, Braille, spacing, and panel margins are added, the proposed panel may no longer be large enough.

Before pricing hundreds of pieces, ask:

• Is the sign identifying a permanent room?
• Is it giving directions?
• Is it providing information?
• Is any content temporary?
• Is an occupant name included?
• Is a pictogram identifying the room?
• Is an accessibility symbol required?
• Does the project have state or local requirements beyond the federal baseline?

Answering those questions before quotation prevents both over-specification and under-specification.

What Tactile and Braille Details Should Be Specified?

“Raised letters with Braille” is not a production specification.

A manufacturer needs the approved text, sign dimensions, character size, typography, Braille content, Braille location, pictogram layout, edge clearance, and mounting relationship before the sign can be engineered reliably.

Federal ADA technical requirements provide measurable controls for raised characters. Raised characters must project at least 1/32 inch from the background, use uppercase characters, and use sans-serif character forms rather than italic, script, highly decorative, or unusual styles. The Access Board guide shows tactile character heights generally ranging from 5/8 inch to 2 inches when the same characters serve both tactile and visual functions.

Several numbers should therefore be visible in the approved sign detail.

Tactile Element	Federal ADA Reference
Raised character depth	1/32 in. minimum
Character case	Uppercase
Character style	Sans serif
Typical raised character height	5/8–2 in.
Raised-character stroke thickness	15% max. of uppercase “I” height
Character width proportion	Uppercase “O” width 55–110% of uppercase “I” height
Line spacing	135–170% of character height
Braille	Contracted Grade 2
Braille location	Below corresponding tactile text
Minimum tactile-sign mounting baseline	48 in.
Maximum tactile-sign mounting baseline	60 in.

Character spacing is another place where attractive artwork can fail as a production detail.

Tactile characters are read by touch, so letters cannot simply be compressed to make a long room name fit a small panel. The federal guide establishes spacing rules between adjacent raised characters and between lines. A narrow decorative font that works on a computer screen may become unsuitable once tactile stroke width and character spacing are checked.

Take a sign reading:

INFORMATION TECHNOLOGY
EQUIPMENT ROOM
B214

A designer may try to fit all three lines onto an 8 × 8 inch panel. The final layout still needs room for:

• tactile character height;
• character spacing;
• line spacing;
• Braille below the tactile copy;
• panel margins;
• any border;
• any pictogram;
• mounting hardware or hidden fixing zones.

A long message can therefore force a larger sign size or a revised message before production.

Braille also needs more control than a line in the RFQ saying “Braille included.”

The Access Board requires contracted Grade 2 Braille. Unified English Braille is acceptable as Grade 2 Braille for the ADA Standards. Braille must be located below the corresponding raised text; when text spans multiple lines, Braille goes below the full tactile text block.

Braille capitalization is not simply copied from printed uppercase wording. According to the Access Board guidance, capitalization in Braille is generally limited to items such as the first word of sentences, proper names, initials, acronyms, and individual letters where appropriate.

For manufacturing, the RFQ should identify who approves Braille content.

A useful schedule has separate fields for:

• Visible Text
• Tactile Text
• Approved Braille
• Braille Revision
• Approval Date

For example:

Field	Approved Production Value
Sign Code	M-214
Visible Text	MECHANICAL ROOM
Tactile Text	MECHANICAL ROOM
Braille	Approved UEB/Grade 2 file
Room Number	B214
Size	8 × 10 in.
Revision	Rev D
Approval Status	Approved for Production

Avoid asking the factory to choose between conflicting documents.

A common project problem looks like:

Floor plan: MECH. ROOM
Architectural schedule: MECHANICAL ROOM
Sign drawing: MECHANICAL
Email revision: MECH ROOM

Only one version should become the production message.

For a package containing 700 signs, content accuracy should also be measured at sign level rather than batch level.

Suppose the project contains:

• 700 total signs;
• 18 sign types;
• 588 unique messages;
• 510 signs with Braille;
• 47 signs with pictograms;
• 12 floors;
• 2 buildings.

Checking one sample from each sign construction is not enough to verify 588 unique text and Braille combinations.

The QC record should connect each individual sign to the schedule:

QC Field	Example
Sign Code	B-R214
Visible Message	214
Tactile Message	214
Braille	Checked to approved schedule
Pictogram	N/A
Panel Size	8 × 8 in.
Finish	Matte Gray
Mounting	VHB + approved adhesive
Packing Group	Building B / Level 2

iduoduo’s documented ADA and architectural-sign workflow is built around approved sign schedules, tactile and Braille specifications, unique sign codes, and item-by-item content inspection rather than treating all room signs as identical pieces.

How Should Contrast and Finish Be Defined?

Do not write “ADA colors” or “high contrast” and expect every manufacturer to quote the same finish.

The federal ADA Standards require visual characters and backgrounds to have a non-glare finish and to contrast using either light characters on a dark background or dark characters on a light background. The Standards do not establish one universal numerical contrast percentage. The Access Board notes that greater contrast generally improves legibility and that textured or variable backgrounds can reduce effective readability.

That distinction matters because RFQs often contain invented statements such as:

“ADA requires 70% color contrast.”

The federal ADA Standards themselves do not specify one minimum contrast percentage. A project may still impose a numerical requirement through another applicable standard, state rule, architectural specification, accessibility consultant, or owner requirement, but the RFQ should identify the source instead of presenting a project criterion as a universal federal number.

A useful RFQ defines color and finish independently.

Item	Vague Specification	Quote-Ready Specification
Background	Gray	Pantone 432 C
Characters	White	Pantone Cool Gray 1 C
Finish	ADA finish	Matte, non-glare
Panel	Acrylic	1/8 in. acrylic per approved detail
Surface	Painted	Two-face painted finish per sample
Contrast	High contrast	Light characters on dark background
Pictogram	Restroom icon	Approved vector artwork Rev B
Reference	Match drawing	Match approved physical sample PS-03

Color names are especially risky.

“Charcoal,” “cream,” “champagne,” “bronze,” “warm white,” and “dark gray” can describe many visibly different finishes.

For a single office sign, a small difference may be acceptable.

For a 900-sign hospital project released in three batches, uncontrolled color naming can create visible differences between:

• Phase 1 room signs;
• Phase 2 corridor signs;
• later replacement signs;
• future room-number changes.

Where visual consistency matters, the RFQ can specify:

• Pantone reference;
• RAL reference;
• manufacturer paint code;
• CMYK value for printed graphics;
• approved physical material sample;
• approved painted sample;
• gloss level where specified;
• surface texture;
• brushed-metal direction;
• revision number.

Non-glare is not the same as “completely flat.”

A matte painted acrylic, satin laminate, brushed metal plate, and textured surface can all behave differently under corridor lighting. Highly reflective materials can create glare even when the foreground and background colors look strongly different in a rendering.

The installed environment matters too.

A sign opposite a large window receives very different reflections from a sign in a dim hotel corridor. A brushed stainless-steel insert under downlights can appear much brighter from one viewing angle than another. A dark glossy background can reflect ceiling fixtures and interfere with character recognition.

For large projects, request a physical finish sample before mass production when:

• corporate colors are tightly controlled;
• metal finishes are used;
• paint matching is critical;
• multiple production batches are expected;
• replacement signs will be ordered later;
• the sign is installed under strong directional lighting.

Braille does not need the same visual color contrast as raised visual characters. The Access Board guide specifically distinguishes Braille from the contrast requirements applied to visual and raised text.

Pictograms deserve separate control.

Where a pictogram designates a permanent room or space, the pictogram field must be at least 6 inches high, and the pictogram and field must use non-glare finishes with light-on-dark or dark-on-light contrast. The required raised and Braille text descriptor sits below the pictogram field rather than inside it.

A production drawing should therefore identify:

Pictogram Detail	RFQ Requirement
Pictogram function	Permanent room / informational / directional
Artwork	Approved vector file
Field height	Per approved ADA detail
Foreground color	Approved reference
Background color	Approved reference
Finish	Non-glare where required
Tactile descriptor	Required / not required
Braille	Required / not required
Revision	Drawing revision

That gives the manufacturer enough information to quote the actual sign instead of guessing from a rendered image.

Who Is Responsible for Final ADA Approval?

The RFQ should state who approves code interpretation, sign content, Braille, mounting location, and final installation. A manufacturer should be responsible for producing signs correctly against the approved manufacturing package, but a remote factory should not be expected to make project-specific legal decisions that depend on local regulations, architectural conditions, door configurations, or site inspection.

A clear responsibility matrix prevents an expensive question after production:

“Who approved this?”

Decision	Typical Responsible Party
Applicable ADA/state/local rules	Architect / accessibility consultant / code professional
Sign-function classification	Architect / signage consultant
Final room names	Architect / facility team
Final room numbers	Architect / contractor
Tactile requirement	Accessibility/design team
Braille wording	Authorized accessibility/design reviewer
Pictogram selection	Architect / signage consultant
Material approval	Architect / designer
Color approval	Architect / brand team
Mounting location	Architect / accessibility consultant
Mounting height	Architect / accessibility consultant
Wall substrate confirmation	Contractor / installer
Manufacturability review	Manufacturer
Shop drawings	Manufacturer
Tactile/Braille production	Manufacturer
Sign-by-sign content QC	Manufacturer
Sample production	Manufacturer
Sample approval	Authorized project representative
Final site compliance	Local responsible professional / authority

Mounting is a good example of why responsibility must be divided correctly.

Federal ADA guidance places tactile characters between specific vertical limits: the baseline of the lowest tactile character must be at least 48 inches above the finished floor, while the baseline of the highest tactile character must be no more than 60 inches above the finished floor.

The sign also needs an 18 × 18 inch minimum clear floor space centered on the tactile characters. That space must be outside the swing of a door opened to 45 degrees and free of interfering protrusions within the defined area.

Door configuration affects horizontal placement.

For a single door, the tactile sign is generally located on the latch side. If there is insufficient wall space there, the nearest adjacent wall is used. With double doors where only one leaf is active, the sign is placed on the inactive leaf; where both leaves are active, it is placed to the right of the doorway. Certain doors with closers and no hold-open device allow placement on the push side of the door.

Those details cannot always be resolved from a sign schedule.

A factory drawing may show:

“Install on latch side.”

The actual site may contain:

• a glass sidelight;
• full-height glazing;
• narrow wall return;
• double active doors;
• wall controls;
• fire alarm devices;
• trim projecting into the sign zone;
• an outward-swinging door;
• decorative wall panels;
• existing signage.

The manufacturer can provide the sign, mounting tape, studs, screws, template, or installation drawing. The local project team still needs to verify that the intended mounting location works with the actual doorway and building conditions.

The RFQ should therefore include a sign-off sequence.

Approval Stage	Suggested Status
Sign schedule	Approved
Sign classifications	Approved
Sign-type drawings	Approved
Visible text	Approved
Tactile text	Approved
Braille	Approved
Pictograms	Approved
Materials	Approved
Colors	Approved
Finish	Approved
Mounting detail	Approved
Sample	Approved where required
Packing plan	Approved
Production revision	Frozen

A production order should not be released because someone wrote “Looks good” in an email without identifying which drawing revision was reviewed.

A stronger approval record looks like:

Project: Riverside Medical Center
Drawing: ADA-Room-Sign-Type-R03
Revision: Rev D
Sign Schedule: Rev F
Sample: GS-02
Braille File: Rev C
Approved By: Project Accessibility Consultant
Approval Date: August 22, 2026
Status: Approved for Production

That gives design, procurement, manufacturing, QC, and installation teams the same production reference.

iduoduo’s documented manufacturing boundary follows the same principle. The factory can manufacture according to approved sign schedules, project drawings, tactile-character and Braille specifications, visual-contrast requirements, material and finish standards, mounting details, unique sign codes, and packing instructions. Final legal interpretation, mounting position, local approval, and site acceptance remain with the project’s architect, accessibility consultant, contractor, or local authority.

For an ADA sign RFQ, the safest wording is therefore not:

“Supplier guarantees all signs are ADA compliant everywhere.”

A more workable instruction is:

“Manufacture according to the approved project accessibility criteria, sign schedule, drawings, tactile and Braille specifications, material schedule, and mounting details. List any conflicts or missing information before production. Final project-specific code interpretation and site approval remain with the authorized project professionals.”

That arrangement gives the factory a clear production standard while keeping regulatory decisions with the people who know the building, jurisdiction, and approved project documents.

How Should Materials and Mounting Be Specified?

An ADA sign RFQ should define the panel material, thickness, layer construction, color, finish, edge treatment, mounting method, wall substrate, hardware scope, and installation conditions for each sign type. Where a detail is not fixed, mark it for manufacturer recommendation rather than leaving it blank. Material and mounting choices directly affect unit cost, durability, tactile construction, packaging, installation labor, and replacement compatibility.

Which Material and Thickness Should Be Listed?

Do not specify only “acrylic ADA sign.” Acrylic can describe several very different constructions, and two manufacturers may price completely different products while both appear to follow the RFQ.

A more useful material specification identifies the complete build-up.

For example:

• 1/8 in. acrylic face
• painted matte finish
• raised tactile copy
• Braille per approved schedule
• second-layer acrylic backer
• total finished thickness
• adhesive mounting
• individually labeled by room number

For layered signs, state each layer separately rather than giving only the total thickness.

Construction Item	Example RFQ Entry
Face material	Acrylic
Face thickness	1/8 in.
Backer material	Acrylic
Backer thickness	1/8 in.
Total nominal thickness	1/4 in.
Tactile characters	Raised per approved ADA detail
Braille	Per approved schedule
Surface	Matte painted
Edge	Smooth finished edge
Mounting	VHB + approved silicone
Environment	Interior corridor

Thickness affects more than material cost.

It can change:

• panel rigidity;
• finished weight;
• edge appearance;
• engraving or routing depth;
• attachment method;
• adhesive contact area;
• shipping protection;
• resistance to warping;
• compatibility with existing frames;
• visual match with earlier phases.

A 4 × 6 inch office plaque and a 16 × 24 inch directional panel should not automatically use the same construction just because both are made from acrylic.

For larger panels, a thin sheet can flex during handling or installation. A thicker construction may improve rigidity but also increases weight, material consumption, carton weight, and freight cost.

Material selection should therefore be tied to actual sign size.

A useful schedule might look like:

Sign Code	Size	Material	Face	Backer	Total Thickness
R-01	8 × 8 in.	Acrylic	1/8 in.	1/8 in.	1/4 in.
RR-01	8 × 10 in.	Acrylic	1/8 in.	1/8 in.	1/4 in.
D-01	18 × 8 in.	Acrylic	3/16 in.	None	3/16 in.
DIR-02	24 × 12 in.	Acrylic + metal	Per drawing	Per drawing	Per drawing

When dimensions are already controlled by architectural specifications, copy them directly into the RFQ.

When thickness has not been finalized, do not invent a number simply to complete the spreadsheet.

Use wording such as:

“Material: acrylic. Thickness: manufacturer to recommend based on 18 × 8 in. panel size, painted drywall mounting, interior use, and concealed adhesive installation.”

That gives the factory enough information to make a meaningful proposal.

The same logic applies to alternative materials.

An architectural package may use:

• acrylic;
• photopolymer;
• painted aluminum;
• stainless steel;
• brass accents;
• layered acrylic and metal;
• PVC for selected non-regulatory elements;
• removable inserts;
• laminate systems;
• project-specific composite structures.

The RFQ should identify whether the selected material is:

• mandatory under the architectural specification;
• based on an approved sample;
• open to equivalent alternatives;
• open to manufacturer recommendation.

That distinction has a direct commercial effect.

For example:

RFQ Status	Wording
Mandatory	“1/8 in. acrylic face required. No substitution.”
Equivalent allowed	“1/8 in. acrylic or approved equivalent.”
Recommendation requested	“Manufacturer to recommend construction.”
Sample-controlled	“Match approved sample AS-04.”

Where a substitute material is allowed, require the quotation to identify the substitute clearly.

Do not accept a quotation that simply says:

“ADA signs — USD 18.50/pc.”

A better quotation identifies:

“1/8 in. matte painted acrylic face + 1/8 in. acrylic backer, tactile copy, Braille, adhesive mounting.”

Now the price can be compared against another offer.

Material also affects cleaning and maintenance.

For hospitals, schools, hotels, clinics, and public facilities, ask whether regular cleaning is expected. Aggressive cleaners, repeated wiping, alcohol-based products, or disinfectants may affect printing, coatings, adhesives, inserts, or surface finishes differently.

If cleaning requirements are important, state them in the RFQ.

For example:

“Signs will be installed in a healthcare environment and cleaned regularly. Manufacturer to confirm recommended surface and cleaning limitations.”

For replacement or phased projects, material consistency deserves another field:

“Must match existing approved sign system: Yes / No.”

If yes, provide:

• original material;
• original thickness;
• original finish;
• original color reference;
• original approved sample where available;
• photographs;
• previous purchase-order or drawing reference.

iduoduo’s internal material-engineering framework treats material as a combination of appearance, strength, surface, mounting, environmental suitability, packing, transportation, maintenance, and repeat-order consistency rather than only a material name.

That is the level of information an RFQ should provide.

How Should Colors and Finishes Be Defined?

Never rely on color names such as “dark gray,” “off-white,” “champagne,” “silver,” or “bronze” when color consistency matters.

Those words are useful in conversation but weak production specifications.

A quotation-ready color field should use a controlled reference whenever available:

• Pantone;
• RAL;
• CMYK;
• RGB for artwork reference;
• manufacturer paint code;
• approved laminate code;
• approved material sample;
• approved painted chip;
• physical golden sample.

A practical finish schedule might contain:

Sign Element	Color	Reference	Finish
Background	Dark gray	Pantone 432 C	Matte
Raised characters	White	Pantone White	Matte
Backer	Warm gray	Approved Sample C-02	Satin
Pictogram	White	Artwork Rev D	Matte
Metal accent	Natural stainless	Sample M-01	Brushed
Insert	White	Material Code A17	Low-glare

The word “matte” also should not automatically be treated as a complete finish specification.

A painted matte acrylic surface, matte laminate, etched acrylic, brushed metal, and textured coating can all produce different appearances and different reflections.

Where the finish is visually important, specify:

• gloss level if controlled;
• texture;
• brushed direction;
• grain direction;
• coating type;
• printed or painted surface;
• edge finish;
• front-face and back-face treatment;
• whether protective film is required during shipment.

Federal ADA requirements for visual signs require characters and their backgrounds to have non-glare finishes and contrast through light-on-dark or dark-on-light presentation. The standard does not establish one universal numerical contrast percentage.

For RFQ preparation, avoid writing:

“70% ADA contrast required”

unless the number comes from the project’s actual governing specification.

A better entry is:

“Light characters on dark background. Matte non-glare finish. Colors per approved architectural finish schedule.”

If the architect, accessibility consultant, or local standard requires a measured contrast criterion, identify it separately:

“Contrast criterion: per Project Specification 10 14 00, Section 2.4.”

That tells the manufacturer where the requirement came from.

Lighting conditions also matter.

A sample that looks good on a desk can look very different:

• opposite a large window;
• beneath recessed downlights;
• beside polished stone;
• under warm hotel corridor lighting;
• inside a bright clinical interior;
• against glass;
• beside reflective stainless-steel door frames.

For high-volume projects, request a physical material or finish sample before mass production when:

• more than one production batch is expected;
• the sign system is brand-sensitive;
• replacement signs will be ordered later;
• metallic finishes are used;
• printed colors must match painted walls;
• two or more materials meet on the same plaque;
• the project contains several hundred signs.

The sample approval should carry a reference number.

For example:

Finish Sample: FS-03
Background: Pantone 432 C
Characters: Warm White
Surface: Matte
Approved: August 18, 2026
Applies to: R-01, R-02, RR-01, S-01

That becomes much more useful than an email saying:

“Gray looks fine.”

Batch consistency also needs realistic language.

If 1,000 signs are produced over three phases, the RFQ can require the factory to retain the approved color and finish reference, but later batches may still need reconfirmation because raw material, paint, laminate, and printing batches can vary.

Use:

“Retain approved color and finish reference for repeat production. Reconfirm material and finish before later phases.”

For metal elements, define the visual direction.

Brushed stainless steel, for example, can look noticeably different if the grain runs vertically on one sign and horizontally on another.

The finish schedule should state:

“Brushed direction: horizontal”

or:

“Brushed direction: vertical.”

For printed graphics, specify whether production should be based on:

• CMYK file;
• Pantone reference;
• physical proof;
• approved printed sample.

Screen colors alone should not become the production standard.

A monitor displaying RGB artwork cannot guarantee how a paint, laminate, acrylic, or printed surface will appear physically.

What Mounting Method Should You Specify?

Mounting should be treated as a product specification, not an installation note added after pricing.

The same 8 × 8 inch ADA room sign may require different materials, back preparation, hardware, packaging, and installation labor depending on whether it attaches with tape, adhesive, screws, studs, standoffs, rails, clips, or another system.

The RFQ should identify:

• mounting method;
• wall substrate;
• whether drilling is allowed;
• hardware included or excluded;
• adhesive included or excluded;
• template required or not;
• removable or permanent installation;
• existing hole pattern if applicable;
• required stand-off distance;
• concealed or exposed fixings.

A useful mounting matrix looks like:

Mounting Method	Common RFQ Information Needed	Main Pricing Effect
VHB tape	Wall type, sign weight, surface condition	Tape preparation and material
Tape + silicone	Wall type, installation method	Adhesive kit and back preparation
Stud mount	Stud size, spacing, wall type	Drilling and stud fabrication
Screw mount	Screw type, hole position, caps	Machining and hardware
Standoffs	Diameter, projection, finish	Hardware and drilling
Rail/clip	Rail profile, length, wall interface	Additional fabricated parts
Existing holes	Hole coordinates	Custom drilling/template work
Removable system	Insert/frame detail	Additional components

Do not write only:

“Wall mounted.”

That leaves the most important installation detail unresolved.

For example:

Mounting: Wall mounted

could mean:

• double-sided tape;
• VHB;
• tape plus silicone;
• screw-fixed plaque;
• concealed studs;
• aluminum rail;
• decorative standoffs.

Each option has a different cost.

A better RFQ line is:

“Mounting: concealed VHB tape + project-approved silicone to painted drywall. Factory to provide tape applied to sign back. Silicone supplied by installer.”

Now the commercial scope is clear.

Hardware scope should also be explicit.

Use a field such as:

Mounting hardware included: Yes / No / Partial

Then list the parts:

• tape;
• studs;
• screws;
• anchors;
• standoffs;
• caps;
• clips;
• rails;
• silicone;
• drilling template;
• paper positioning template;
• installation drawing.

A frequent site problem occurs when the installer opens the cartons and discovers that everyone assumed someone else was supplying anchors.

For a 600-sign package, one missing hardware kit can delay installation across multiple floors.

Ask for hardware quantity by sign or by package.

For example:

R-01: 286 signs
Mounting: VHB applied to rear
Additional hardware: None

D-01: 46 signs
Mounting: 2 concealed screws per sign
Hardware: 92 screws + 92 anchors + 10% spare

If spare hardware is required, state the percentage.

Typical project instructions might specify:

“Provide 5% spare mounting hardware.”

or:

“Provide 10 complete spare mounting kits per sign type.”

Do not invent a universal percentage; use the actual project requirement.

Templates deserve the same clarity.

A template can be useful when:

• multiple holes need precise spacing;
• studs must align with drilled walls;
• hundreds of identical signs share one mounting pattern;
• signs must align consistently beside doors;
• a layered or multi-part sign must be assembled on site.

The RFQ should state whether the template is:

• full-size paper;
• acrylic;
• cardboard;
• reusable;
• one per sign;
• one per sign type;
• one per installation crew.

For a 20-floor project, “one template supplied” may be insufficient if several installation crews work simultaneously.

Manufacturability review should connect mounting to sign construction. iduoduo’s documented engineering process includes structure, materials, mounting preparation, shop drawings, sections, BOM control, finish schedules, and final production approval.

Which Wall Details Affect the Quote?

Wall substrate can change the mounting method even when the sign itself remains visually identical.

The RFQ should identify the actual installation surface for each sign type.

Common surfaces include:

• painted drywall;
• gypsum board;
• wallpaper;
• glass;
• ceramic tile;
• porcelain tile;
• natural stone;
• engineered stone;
• concrete;
• brick;
• wood;
• millwork;
• metal panel;
• stainless-steel door;
• painted door;
• acoustic panel;
• textured wall covering.

A useful wall-condition field could read:

Sign Code	Wall Surface	Drilling	Adhesive	Existing Holes
R-01	Painted drywall	No	Allowed	No
RR-01	Ceramic tile	Avoid	Allowed	No
D-01	Concrete	Yes	No	No
O-01	Glass	No	Yes	No
ST-01	Painted metal	Per drawing	Per drawing	Existing

Wall condition affects quotation because mounting preparation changes.

Painted drywall may allow adhesive installation.

Stone may require:

• drilling;
• anchors;
• mechanical fixing;
• special adhesives;
• longer installation time.

Glass may require:

• adhesive mounting;
• back-side cover plate;
• visual masking;
• precise alignment from both sides.

Tile introduces another issue: drilling through tile may create breakage risk, while grout lines can affect placement.

Wallpaper and textured surfaces may reduce adhesive contact.

Fresh paint can also affect adhesive performance. If signs are installed immediately after painting, the installer may need to follow adhesive or paint-curing recommendations.

The RFQ does not need to become an adhesive engineering manual, but it should tell the manufacturer enough to prepare the correct sign back and included hardware.

For renovation projects, wall conditions deserve even more attention.

Provide photographs showing:

• old sign;
• old mounting position;
• old adhesive footprint;
• screw holes;
• wall damage;
• wall texture;
• door frame;
• nearby switches;
• fire alarm devices;
• glass sidelights.

Also provide basic measurements.

For example:

Existing sign: 8 × 8 in.
Existing holes: 6.00 in. center-to-center
Existing sign removed: Yes
Old adhesive remains: No
New sign must cover old footprint: Yes
Drilling new holes permitted: No

Those details may determine the new sign size and back construction before anyone discusses color.

Existing-hole reuse can be especially important for hotels, hospitals, and occupied office buildings where drilling hundreds of new holes is undesirable.

If existing holes must be reused, provide a dimensioned drawing rather than a photograph alone.

Use:

Hole 1: X = 1.00 in., Y = 1.00 in.
Hole 2: X = 7.00 in., Y = 1.00 in.

The factory can then reproduce the mounting pattern.

For replacement orders, ask:

“Must replacement signs use original mounting interface: Yes / No.”

If yes, include the original drawing or physical sample wherever possible.

Wall flatness also matters for larger signs.

A long acrylic directional panel mounted to an uneven stone or textured wall may rock or leave visible gaps. A rail, thicker backer, mechanical mounting system, or stand-off structure may be more appropriate than relying on tape across the entire rear face.

Exterior wall conditions introduce additional considerations such as:

• moisture;
• temperature;
• UV exposure;
• wind;
• corrosion;
• substrate movement;
• sealant compatibility.

An ADA sign is often an interior product, but wayfinding and accessibility signage can also appear in exterior or semi-exterior environments. The RFQ should identify “interior,” “exterior,” or “covered exterior” rather than letting the factory assume.

Are Installation Locations Required in the RFQ?

A full installation plan is not always necessary for the first budget quotation, but the RFQ should provide enough location information to identify the sign function, wall condition, mounting interface, and any accessibility-sensitive placement.

For tactile signs, mounting location is part of the accessibility requirement, not simply a decorating decision.

Under the federal ADA Standards, tactile characters must be positioned so the baseline of the lowest tactile character is at least 48 inches above the finished floor or ground and the baseline of the highest tactile character is no more than 60 inches above the finished floor or ground.

The Access Board also requires an 18 × 18 inch minimum clear floor space centered on the tactile characters. The clear space must be located outside the door swing through the 45-degree open position.

Door configuration also affects horizontal sign location.

For single doors, tactile signs are generally positioned on the latch side. Other rules address double doors, insufficient wall space, and certain door configurations.

For RFQ purposes, location information should therefore include more than a room number.

Useful fields are:

• building;
• floor;
• room;
• door identification;
• latch side;
• wall substrate;
• door type;
• single or double door;
• sidelight present;
• nearby obstruction;
• proposed sign position;
• installation drawing reference.

For example:

Field	Example
Building	Tower A
Floor	06
Room	0612
Door	D-0612
Door Type	Single leaf
Latch Side	Right
Wall	Painted drywall
Sidelight	No
Obstruction	Thermostat 14 in. from jamb
Sign Code	R-01
Mounting Detail	MD-03
Location Approval	Architect

Floor plans are particularly useful when the sign package includes:

• directional signs;
• multiple door configurations;
• glass sidelights;
• changing room numbers;
• several buildings;
• mirrored layouts;
• renovation work.

A room schedule alone cannot show which way an arrow should point.

A directional sign reading:

“ROOMS 201–220”

could require:

← ROOMS 201–220

or:

ROOMS 201–220 →

depending on the actual corridor location.

For a 40-sign directional package, one unverified arrow direction can create a field replacement even when every material and dimension is correct.

Include the sign-location plan or floor plan in the RFQ when direction matters.

Installation height should also be handled carefully.

Do not instruct the factory to decide site mounting height from a generic product page.

The responsible architect, accessibility consultant, contractor, or local authority should approve the project-specific location and mounting height.

The factory can provide:

• sign dimensions;
• tactile layout;
• mounting-hole pattern;
• sign centerline;
• mounting template;
• hardware;
• installation drawing.

The local project team should confirm that the proposed location works with:

• finished floor level;
• door swing;
• door hardware;
• glass sidelights;
• electrical devices;
• wall trim;
• handrails;
• fire alarm equipment;
• wall panels;
• other signage.

A practical RFQ approval workflow is:

Installation Item	Manufacturer	Project Team
Sign dimensions	Prepare	Approve
Mounting holes	Prepare	Approve
Hardware	Supply if included	Confirm substrate compatibility
Template	Prepare if required	Use on site
Wall substrate	Review information	Confirm
Door configuration	Review drawing	Confirm
Mounting height	Follow approved detail	Approve
Final wall position	Follow approved plan	Approve
Site code compliance	Not final authority	Local responsible party

iduoduo’s architectural-sign manufacturing scope follows the same boundary: manufacturing can proceed from approved sign schedules, project drawings, material and finish standards, mounting details, and unique sign codes, while final mounting location and local compliance approval remain with the responsible project professionals.

Before releasing an ADA sign package for quotation, the material and mounting fields should therefore answer five practical questions:

• What is the sign made from?
• How thick is the finished construction?
• What exact finish must be reproduced?
• How is the sign attached?
• What surface is it attaching to?

Before releasing the same package for production, add two more:

• Where exactly will it be installed?
• Who approved the mounting detail?

When those seven answers are controlled in the RFQ, material quotations become easier to compare, mounting hardware is less likely to be omitted, and the risk of discovering an installation problem after hundreds of signs have already been manufactured drops significantly.

How Do You Make ADA Sign Quotes Comparable?

ADA sign quotes become comparable only when every manufacturer prices the same revision, sign schedule, construction, tactile/Braille scope, mounting hardware, sample requirement, packing method, freight basis, and delivery target. Compare scope before unit price. A quote that excludes samples, hardware, labeling, or floor-by-floor packing may look cheaper even though the final project cost is higher.

What Should Every Manufacturer Quote?

Ask every manufacturer to quote from the same RFQ package and require the quotation to repeat the exact drawing and sign-schedule revision used for pricing.

A quotation should not begin with only:

“ADA signs: 500 pcs × $18.50.”

For a project with hundreds of unique room numbers, several sign constructions, Braille, pictograms, mounting accessories, and phased delivery, one unit price hides too much information.

The quote should identify at least:

• project name;
• quotation number;
• quotation date;
• sign schedule revision;
• drawing revision;
• total sign quantity;
• quantity by sign code;
• material construction;
• tactile character scope;
• Braille scope;
• pictogram scope;
• finish and color;
• mounting hardware;
• sample cost;
• tooling or setup charges;
• labeling;
• packing method;
• freight basis;
• production lead time;
• payment terms;
• warranty;
• exclusions;
• assumptions;
• quote validity.

A useful comparison sheet might look like:

Quote Item	Manufacturer A	Manufacturer B	Manufacturer C
Sign Schedule	Rev F	Rev F	Rev E
Total Quantity	684	684	658
Sign Types	14	14	12
Unique Messages	527	527	Not stated
Raised Characters	Included	Included	Included
Braille	Included	Included	Partial
Pictograms	Included	Included	Not clear
Mounting Hardware	Included	Extra	Excluded
Production Sample	Included	$280	Excluded
Individual Labels	Included	Included	No
Floor Packing	Included	$420 extra	Bulk cartons
Export Packing	Included	Included	Included
Freight	DDP	FOB	Excluded
Production Lead Time	18 days	15 days	12 days

Manufacturer C may show the lowest unit price, but it is not yet a comparable quotation because the scope is different.

The first check should therefore be:

“Did all three factories quote the same quantity and revision?”

If the project schedule contains 684 signs but one quotation lists 658, do not compare the total prices until the missing 26 pieces are identified.

The second check is construction.

A line reading “acrylic ADA room sign” can hide major differences.

Ask the quotation to state:

Construction Detail	Example
Face	1/8 in. acrylic
Backer	1/8 in. acrylic
Finished thickness	Approx. 1/4 in.
Finish	Matte painted
Raised text	Included
Braille	Included
Pictogram	Where shown
Mounting	VHB applied
Individual label	Room number + sign code

If one quote uses a single acrylic layer and another uses a layered system, the numbers should not be compared as though the products were identical.

The same rule applies to Braille.

The quotation should state whether the price includes:

• Braille production;
• Braille content preparation;
• Braille content checking;
• tactile characters;
• tactile pictogram descriptor;
• individual message changes.

For a project containing 510 Braille signs and 470 unique messages, message-level production and QC represent real labor.

Mounting also needs a commercial value.

Ask:

• Is VHB tape included?
• Is silicone included?
• Are screws included?
• Are anchors included?
• Are standoffs included?
• Is a drilling template included?
• Is hardware packed per sign?
• Are spare hardware kits included?

A difference of $0.30–$1.50 in hardware per sign can become meaningful across 800 or 1,000 signs.

The same principle applies to commercial terms.

A $20.00 sign quoted FOB China is not directly comparable to a $22.00 sign quoted DDP to a U.S. project site.

Separate:

Product cost

• Sample/tooling
• Packing
• Freight
• Import-related charges where applicable
  = Landed project cost

The lowest ex-factory price is not automatically the lowest delivered cost.

iduoduo’s inquiry framework is built around clear product scope, engineering review, materials, mounting, QC, packing, logistics, warranty, and documented project requirements rather than relying on a headline unit price.

Do You Need a Sample Before Production?

For large ADA sign packages, a physical sample is usually worth approving before bulk production, especially when color, tactile quality, Braille, pictograms, layered construction, mounting, or finish are important.

A sample can reveal problems that are difficult to judge from a PDF.

For example:

• tactile characters feel too sharp;
• Braille alignment is incorrect;
• matte finish is glossier than expected;
• background color appears different under corridor lighting;
• panel thickness feels too light;
• edges need better finishing;
• pictogram proportions look crowded;
• tape placement interferes with installation;
• sign size becomes too small after ADA spacing is applied;
• packaging marks the painted face.

A useful sample approval should cover more than appearance.

Sample Check	What to Confirm
Overall dimensions	Width, height, thickness
Material	Correct layer construction
Color	Matches approved reference
Finish	Matte/non-glare as specified
Tactile text	Correct content and physical quality
Braille	Correct approved content and placement
Pictogram	Correct artwork and proportion
Edge	Smooth, clean, consistent
Mounting	Correct tape/hardware
Back side	Correct label and preparation
Packing	No surface marking or damage

For a project with several constructions, one sample may not be enough.

Suppose a project contains:

• R-01 standard room sign;
• RR-01 restroom sign with pictogram;
• ST-01 stair sign;
• D-01 directional sign;
• O-01 changeable office sign.

The five signs may use different sizes, layouts, materials, pictograms, inserts, and mounting systems.

A practical sample plan could be:

Sign Type	Qty in Project	Sample
R-01 Room ID	286	Yes
RR-01 Restroom	24	Yes
ST-01 Stair	32	Yes
D-01 Directional	46	Optional / recommended
O-01 Office Insert	19	Yes

The purpose is not to sample every room number.

It is to approve each major construction before quantity multiplies the risk.

For very large or repeat projects, the approved sample can become the golden sample.

That reference can control:

• color;
• panel thickness;
• edge treatment;
• tactile quality;
• Braille appearance;
• printing;
• back construction;
• mounting hardware;
• labeling;
• packaging.

The factory should then transfer the approved result into controlled production documents rather than relying only on the physical sample.

iduoduo’s documented sampling process can include material samples, color samples, prototypes, pre-production samples, golden samples, first-article approval, first-store validation, and pilot production. Approved results can be transferred into drawings, BOMs, process standards, mounting specifications, QC requirements, and controlled production versions.

For quotation comparison, require every manufacturer to state:

Sample required: Yes / No
Sample quantity:
Sample cost:
Sample production time:
Sample shipping cost:
Sample approval required before bulk: Yes / No
Sample cost refundable against order: Yes / No

Otherwise, one manufacturer may include a sample in the quotation while another assumes direct mass production.

How Should Packing and Labeling Be Defined?

ADA sign packing should be priced as part of the project workflow, especially when hundreds of signs contain unique room numbers, Braille messages, sign codes, floors, or buildings.

Bulk packing can reduce packing labor, but it can transfer sorting work to the installation team.

Imagine 720 signs arriving in 18 cartons with no room labels.

The installer may need to:

• open every carton;
• read every sign;
• sort by building;
• sort by floor;
• sort by room number;
• match mounting hardware;
• rebuild installation sequences.

A lower packing cost at the factory can create much higher labor cost on site.

For project-based orders, define the packing level before quotation.

Packing Level	Typical Use
Bulk by sign type	Small/simple projects
Individual sign protection	Finished/tactile surfaces
Label by sign code	Unique-message projects
Pack by floor	Hotels, offices, hospitals
Pack by building	Multi-building developments
Pack by installation zone	Large phased projects
Pack by store/site	Multi-location programs

For ADA and wayfinding projects, a label can include:

Project: Riverside Hotel
Building: Tower B
Floor: 07
Room: 0714
Sign Code: R-01
Package: B07-14

That label helps manufacturing, QC, packing, receiving, and installation use the same identifier.

For multi-floor projects, carton labeling can follow:

Tower B
Level 07
Signs B-R701 through B-R724
Carton 12 of 36

The packing list should show:

• carton number;
• building;
• floor;
• sign-code range;
• number of signs;
• accessories included;
• gross weight;
• carton dimensions.

ADA signs also need surface protection.

Braille dots, raised characters, printed faces, painted surfaces, insert windows, and edges can be damaged by direct contact with other signs.

Packing should prevent:

• Braille dots rubbing another panel;
• raised letters scratching painted surfaces;
• loose mounting hardware moving across sign faces;
• edge chipping;
• bending;
• surface abrasion;
• insert loss;
• room-number mix-ups.

iduoduo’s internal ADA and wayfinding packing standard calls for organization by sign code, room number, floor, area, building, and installation sequence, with protection for Braille, tactile characters, printed surfaces, inserts, edges, and mounting accessories.

Mounting hardware should also be separated from the finished face.

For example:

R-214 sign

• individual protective sleeve
• mounting kit in labeled bag
• room/sign-code label

For larger quantities, ask manufacturers to quote two packing options if the project team has not decided:

Option A: standard bulk export packing
Option B: individual labeling + floor-sorted packing

Now the extra organizational cost is visible rather than being added after the order is placed.

What Lead Times Should Be Confirmed?

Do not compare lead times unless every manufacturer is measuring from the same starting point.

“15-day lead time” can mean very different things.

Manufacturer A may mean:

15 days after approved drawings and sample.

Manufacturer B may mean:

15 days after deposit.

Manufacturer C may mean:

15 days after materials arrive.

A useful RFQ separates the schedule into actual stages.

Stage	Target / Quoted Time
RFQ review	1–3 working days
Quote preparation	Manufacturer to state
Shop drawings	Manufacturer to state
Drawing approval	Project team
Sample production	Manufacturer to state
Sample shipping	Carrier-dependent
Sample approval	Project team
Material preparation	Manufacturer to state
Bulk production	Manufacturer to state
Final QC	Manufacturer to state
Packing	Manufacturer to state
International shipping	Route-dependent
Site delivery	Required date

The required date should be the arrival date, not only the factory completion date.

There is a major difference between:

“Production complete October 10”

and:

“Delivered to Chicago jobsite by October 10.”

For imported signs, the schedule can include:

Production
→ QC
→ Packing
→ Pickup
→ Export handling
→ International transport
→ Customs
→ Local delivery

If the project opening date is fixed, work backward from the required arrival date.

For example:

Required installation start: November 15
Required site delivery: November 5
Target customs clearance: October 31
Target shipment departure: October 20
Target factory completion: October 16
Target production start: September 28
Required final approval: September 25

That timeline tells everyone when late artwork changes stop being harmless.

Phased delivery can also reduce schedule pressure.

A 1,200-sign property does not always need every sign at the same time.

One possible release could be:

Phase 1: Guest rooms — 620 signs
Phase 2: Public areas — 310 signs
Phase 3: Back-of-house — 190 signs
Phase 4: Late-change operational signs — 80 signs

The RFQ should state whether manufacturers may propose phased production.

Ask every factory to specify:

• sample lead time;
• bulk lead time;
• start-point definition;
• whether lead time includes QC;
• whether lead time includes packing;
• whether special materials extend the schedule;
• capacity assumption;
• shipping transit estimate;
• holiday or shutdown risk;
• effect of revision after approval.

Do not reward an unrealistically short number.

A 10-day quote based on incomplete artwork may become 25 days after materials, samples, and revisions are included.

The more useful question is:

“What information must be approved before the quoted production lead time begins?”

Which RFQ Gaps Cause Quote Changes?

Most large price revisions can be traced to information that was missing, assumed, or changed after the first quotation.

Common examples include:

• quantity increases;
• new sign types;
• larger dimensions;
• additional material layers;
• tactile characters added;
• Braille added;
• pictograms added;
• special colors;
• metal accents;
• changeable inserts;
• mounting hardware;
• templates;
• individual labeling;
• floor packing;
• multiple delivery addresses;
• samples;
• expedited production;
• air freight instead of sea freight.

A change log makes those revisions easier to control.

Change	Rev A	Rev B	Commercial Effect
Total signs	486	512	+26 signs
Room ID size	8 × 8	8 × 10	More material
Restroom signs	Standard text	Added pictogram	Larger panel
Mounting	Not defined	VHB included	Added hardware
Packing	Bulk	Floor sorted	Added packing labor
Delivery	One shipment	Two shipments	Added logistics

The most dangerous RFQ gaps are usually not dramatic. They are small fields that affect hundreds of pieces.

For example:

Mounting tape = $0.40/sign
600 signs = $240

Individual labels = $0.15/sign
600 signs = $90

Floor sorting = $0.50/sign
600 signs = $300

Extra backer layer = $2.00/sign
600 signs = $1,200

Sample set = $350

The exact figures vary by project and manufacturer, but the commercial lesson remains the same: small unit-level omissions become large order-level differences.

Quantity changes deserve special control.

Suppose the first quotation contains:

Sign Type R-01: 280 pcs

The next architectural revision increases the quantity to:

R-01: 317 pcs

Do not request:

“Please update quote.”

Use:

“Rev D increases R-01 from 280 to 317 pieces, +37 pieces. No construction change.”

Now the price change can be audited.

Construction changes should be recorded separately.

For example:

“Rev E changes R-01 from single-layer acrylic to two-layer acrylic. Quantity unchanged at 317 pieces.”

That identifies whether the commercial movement came from quantity, product structure, or both.

A useful quotation revision log can contain:

• quote revision;
• drawing revision;
• schedule revision;
• quantity change;
• specification change;
• freight change;
• new total;
• lead-time effect.

That prevents conversations such as:

“Why did the quote increase by $2,400?”

from becoming a manual search through weeks of email.

What Should Be Approved Before Production?

Bulk production should begin only when the commercial scope and manufacturing scope point to the same approved revision.

At minimum, confirm:

• final sign schedule;
• final quantity;
• sign codes;
• unique messages;
• visible text;
• tactile text;
• Braille;
• pictograms;
• dimensions;
• material;
• thickness;
• colors;
• finishes;
• mounting;
• hardware;
• sample;
• labels;
• packing method;
• shipping marks;
• delivery phases;
• approved production revision.

A practical release checklist is:

Production Item	Status
Sign Schedule Rev F	Approved
Drawings Rev D	Approved
Total Quantity: 684	Approved
Unique Messages: 527	Approved
Braille File Rev C	Approved
Material	Approved
Color Sample FS-03	Approved
Mounting	Approved
Golden Sample GS-02	Approved
Packing Plan PP-01	Approved
Delivery Phase 1	Approved
Production Status	RELEASED

Do not begin bulk production from phrases such as:

“Looks okay.”

“Please proceed.”

“Use the latest files.”

Those messages are difficult to audit.

A production release should identify the exact files.

For example:

Project: Riverside Medical Center
Sign Schedule: Rev F
Drawing Package: Rev D
Braille File: Rev C
Finish Sample: FS-03
Golden Sample: GS-02
Packing Plan: PP-01
Quantity: 684
Release Date: August 28, 2026
Status: Approved for Production

For ADA signs, content approval is particularly important because many pieces can share one construction while carrying unique messages.

A 500-piece room-sign package may require only one approved physical construction but contain 450 different room numbers and Braille messages.

Therefore two approvals are needed:

Construction approval

and

Content approval

Construction approval confirms:

• size;
• thickness;
• material;
• finish;
• tactile method;
• Braille construction;
• edge;
• mounting;
• packing.

Content approval confirms:

• sign code;
• room number;
• room name;
• Braille;
• pictogram;
• arrow;
• floor/building assignment.

The QC plan should then inspect against those approved records.

For non-illuminated ADA signage, inspection should focus on dimensions, material, finish, tactile content, Braille, edge quality, mounting preparation, accessories, labeling, and packing rather than LED or electrical tests. iduoduo’s internal product standard specifically separates ADA and other non-illuminated signage from LED, power, brightness, and 72-hour lighting-test requirements.

iduoduo’s broader quality framework also uses approved production files, first-article approval, in-process inspection, dimensional and appearance checks, accessory verification, packaging inspection, reinspection after rework, and traceable release records.

A comparable quotation therefore does not end with comparing three totals.

The practical sequence is:

RFQ revision confirmed
→ quantities confirmed
→ construction compared
→ inclusions compared
→ sample scope compared
→ packing compared
→ freight basis compared
→ lead-time basis compared
→ assumptions reviewed
→ landed project cost compared

Only after those checks does the lowest number become meaningful.

Ready to Prepare Your ADA Sign Quote?

A complete ADA sign RFQ does not need to be perfect before it reaches a manufacturer. If the latest sign schedule, drawings, room list, quantities, project location, material requirements, mounting conditions, and target delivery date are already available, those files are usually enough to begin a practical manufacturing review.

iduoduo can review approved project drawings and sign schedules, identify information that still affects pricing or production, and prepare custom ADA signs, room identification signs, Braille signs, wayfinding signs, plaques, and related architectural signage according to the confirmed project requirements. Final local compliance interpretation and installation approval should remain with the architect, accessibility consultant, contractor, or other responsible project professional.

If you are preparing an ADA signage project, send the current RFQ package to iduoduo for review. The next step can be as simple as confirming what is already fixed, what still needs approval, and which details must be resolved before an accurate quotation or production sample can be prepared.
