Where drawings sit
The architect draws what it looks like; the millwork drafter draws how it gets built. What a submittal is in contract terms, what approval covers, and what it never covers.
9 min read
The architect draws what it looks like. You draw how it gets built. Between the two sits the submittal: your drawings, sent up the chain, stamped, and sent back. Once stamped, one set of sheets does two jobs. The shop builds from it, and the work is judged against it. Everything else in this book follows from that.
This chapter places your drawings among the project's documents, using the words of the contracts themselves. It uses two: the American Institute of Architects' A201 General Conditions (2017 edition), a standard form contract, and the US Federal Acquisition Regulation clause 52.236-21, which governs federal construction contracts. Your job may use neither. Learn the ideas here, then read your own contract for the details.
The contract documents, and why yours are not one of them
A201 lists the Contract Documents in §1.1.1: the Agreement, the Conditions of the Contract, the Drawings, the Specifications, Addenda issued before signing, other documents listed in the Agreement, and Modifications issued after signing. The architect's drawings are on that list. Yours are not.
Shop Drawings, Product Data, Samples, and similar submittals are not Contract Documents. Their purpose is to demonstrate how the Contractor proposes to conform to the information given and the design concept expressed in the Contract Documents.
AIA A201-2017, §3.12.4
Read the second sentence twice. Your drawings are a proposal. They answer the question "how will you build what the architect drew?" The architect's drawings stay the contract. If the two disagree, the contract wins, unless the difference was flagged and accepted the proper way (below).
A201 defines shop drawings in §3.12.1 as "drawings, diagrams, schedules, and other data specially prepared for the Work by the Contractor or a Subcontractor, Sub-subcontractor, manufacturer, supplier, or distributor to illustrate some portion of the Work." The millwork shop is usually that subcontractor. The federal clause says much the same: shop drawings show "the proposed fabrication and assembly" and "the installation (i.e., fit, and attachment details)" of the work.
And yet the work must match them
Here is the second job. A201 §3.12.8 opens: "The Work shall be in accordance with approved submittals". Once stamped, your set becomes the standard the finished millwork is checked against. A201 §3.11 then requires the approved shop drawings to be kept at the site and handed over at completion "as a record of the Work as constructed."
So an approved set is:
- A build instruction for the shop floor and the installer.
- The yardstick the owner and architect measure the finished work against.
- Part of the record the building keeps after everyone leaves.
It is not a contract document, and it does not change the contract on its own. That combination is where drafters get hurt. The set carries enough weight to bind the shop, and not enough to protect it.
What approval covers
A201 is precise about the architect's review:
The Architect will review and approve, or take other appropriate action upon, the Contractor's submittals ... but only for the limited purpose of checking for conformance with information given and the design concept expressed in the Contract Documents. ... Review of such submittals is not conducted for the purpose of determining the accuracy and completeness of other details such as dimensions and quantities.
AIA A201-2017, §4.2.7
The same section adds that the review "shall not constitute approval of safety precautions or of any construction means, methods, techniques, sequences, or procedures", and that approving one item "shall not indicate approval of an assembly of which the item is a component."
The federal clause is shorter and harder: "Approval by the Contracting Officer shall not relieve the Contractor from responsibility for any errors or omissions in such drawings." It also says "Any work done before such approval shall be at the Contractor's risk."
Put together, here is what a stamp covers:
| Question | Does the architect's approval answer it? | Where it says so |
|---|---|---|
| Does this match the design concept? | Yes. That is the review. | A201 §4.2.7 |
| Are the dimensions right? | No. Still yours. | A201 §4.2.7 |
| Are the quantities right? | No. Still yours. | A201 §4.2.7 |
| Will the construction method work? | No. Means and methods are not approved. | A201 §4.2.7 |
| Do the errors on the sheet become the architect's? | No. | A201 §3.12.8; FAR 52.236-21(e) |
| Does the building code apply to the design? | The design professional answers for code, under AWI's submittal standard. | AWI 100 §3.4(c) |
A millwork drafter on r/Millwork put the practical version in four sentences:
They will approve your drawing with the same incomplete/unbuildable design. Their approval, while necessary for contract, is meaningless. If you want to know if your drawings are good, ask the people who have to build from them.
A commenter, r/Millwork, "Millwork drafting" thread
"Meaningless" overstates it. The stamp means exactly what §4.2.7 says: the look is accepted. It says nothing about whether the thing can be built, and the contract says so in print.
What you promise when you submit
The act of submitting is itself a statement. A201 §3.12.6: by submitting, the Contractor "represents to the Owner and Architect that the Contractor has (1) reviewed and approved them, (2) determined and verified materials, field measurements and field construction criteria related thereto, or will do so, and (3) checked and coordinated the information contained within such submittals with the requirements of the Work and of the Contract Documents."
That clause binds the general contractor, and the general contractor makes the promise on the strength of your set. When your set goes out, someone is promising that its field measurements are verified or will be, and that it fits the other trades. If a dimension on your sheet came from the architect's plan and nobody has measured the room, mark it. VIF (verify in field) on a dimension is honest. A plain number that nobody measured makes a promise nobody kept.
Changes you draw are not changes you asked for
Drawing a change does not ask for it. A stamp on a set that shows a change does not approve the change. Four sources say so.
| Source | What it says |
|---|---|
| AWI 100 – Submittals, §3.2(b) | "Changes and/or substitutions incorporated into shop drawings do not constitute a request for approval. Changes to material and/or design must be specifically identified within the submittal package." |
| AWI 100, §3.2(c) | Substitutions and change requests "shall be itemized separately from the shop drawings", with "the reason for the change request and a statement of the anticipated impact to schedule, cost, and possible impact to other trades." |
| AIA A201-2017, §3.12.8 | The Contractor stays responsible for deviations "unless the Contractor has specifically notified the Architect of such deviation at the time of submittal" and the architect approves it in writing or a Change Order issues. |
| FAR 52.236-21(f) | "If shop drawings show variations from the contract requirements, the Contractor shall describe such variations in writing, separate from the drawings, at the time of submission." |
| Woodwork Institute sample set, page 3 | "Changes from the original specifications shall be submitted by the fabricator in a separate document signed & approved by the architect prior to fabrication." |
AWI adds one useful carve-out: "Means and methods of manufacturing, such as joinery details, are not considered material changes unless otherwise detailed in the specifications." How you join the box is usually the shop's call. What the box is made of, and what it looks like, is not.
Worked example: a substrate swap
The specification calls for veneered panels on a particular core. The shop stocks a different core and wants to use it. The drafter changes the material callout on the section and sends the set. It comes back "Approved as Noted" with no comment on the core.
Under every source above, the core change is not approved. The drawing showed it; nobody asked for it. If the owner later finds the wrong core, the shop owns it.
The right move is short:
- Write a separate substitution request. Name the specified core and the proposed one.
- Give the reason, and state the effect on schedule, cost and other trades, as AWI 100 §3.2(c) requires.
- Send it with the submittal, not after it.
- Cloud the change on the drawing and point to the request.
- Do not release the part to the floor until the written answer is in the job file.
Drawings, specifications and which one wins
The architect's package is more than drawings. The specification book carries the grade, the standard, the materials and the hardware. It is easy to draw from the architect's sheets and never open it.
The federal clause settles conflicts in one line: "In case of difference between drawings and specifications, the specifications shall govern." A201 §1.2.1 takes a different route: the Contract Documents "are complementary", and what one requires binds as if all required it. Either way, the drawings alone do not tell you what to build.
The Woodwork Institute sample set makes the point on its cover: "All information included in the drawings must comply with architects original specifications." Page 3 of its PDF is a full sheet titled "Specification Requirements", filled in before a line of casework is drawn: case body core, joinery type, edge banding, backs, toe base, door and drawer fronts, drawer box, shelves, countertops, and every hardware item by maker and model. Chapter 21 walks through it.
Whose drawings are they
Two sources give opposite answers, and the difference matters when a drawing gets reused.
- AWI 100 §3.2(a): "Submittals are the intellectual property of the manufacturer/supplier."
- FAR 52.236-21(d): "The Government may duplicate, use, and disclose in any manner and for any purpose shop drawings delivered under this contract."
On a federal job the government can reuse your details. On a job that names AWI 100, the shop keeps them. Your contract decides which applies. Know the answer before you put a proprietary detail on a sheet.
Why the double job shapes everything
A set that serves only the shop can be terse. A set that serves only the architect can be pretty. Yours has to do both, and the readers want different sheets. The architect reads plans and elevations for the design. The shop reads sections and details for construction. An approval stamp lands on the whole set, and it only checked half of it.
So the discipline is simple to state:
- Draw the look clearly enough that the design approval is real.
- Draw the construction completely enough that the shop never has to guess, because nobody upstream checked it.
- List every change outside the drawings, in writing, so the approval covers it.
- Mark every unmeasured dimension, so your set promises only what someone verified.
Checklist: before a set leaves your desk
- You have read the specification section for the millwork, not only the architect's drawings.
- Every departure from the specification is itemised in a separate substitution or change request, with reason and impact.
- Each such change is clouded on the drawing and cross-referenced to its request.
- Every dimension not measured on site is marked VIF or noted as assumed.
- Work by others is labelled as such, so nobody reads it as your scope.
- Someone who builds from drawings has read the sections and details, because the stamp will not.
