A drawing transmittal is your formal record of which drawings, in which revision, went to whom, on which date. It's the paper trail that protects you if drawings are ever disputed.

What a Transmittal Is and Why It Matters

A transmittal is a form (paper or digital) that documents the official distribution of drawings. Every transmittal includes:

Project name and address — so there's no confusion about which project
Date of transmittal — when it was sent
Sender and signature — who is sending it (usually architect, engineer, or GC)
Recipient and contact — who it's going to (GC, subs, owner)
List of drawings — sheet number, sheet name, revision number/date
Purpose code — why it's being sent (For Construction, For Review, For Record, For Coordination)
Signature of receipt — recipient acknowledges they received the drawings

Why it matters: If a dispute arises — "I didn't receive that revision," or "The drawings were unclear" — the transmittal proves who received what, when. It's your protection against claims and change orders.

Transmittal Purpose Codes

Every transmittal has a purpose. Know these four:

For Construction

The drawings are approved and ready to build. This is the official release to the GC and subs. Only transmittals marked "For Construction" authorize work to proceed. Anything sent "For Review" or "For Coordination" is not construction-ready.

For Review

Drawings are sent to a recipient (often the owner, lender, or code official) for review and comment. Work cannot proceed until a "For Construction" transmittal is issued. These are draft drawings; changes are expected.

For Record

Drawings are sent to create a file copy. Typically used near project end to distribute final marked-up or "as-built" versions. These are for documentation, not construction authorization.

For Coordination

Drawings are sent to subs or trades so they can coordinate their own work. Not final approval; the receiving party should review for conflicts and submit comments. Common between MEP engineers and the general contractor.

Who Sends Transmittals and to Whom

Transmittals flow through the project hierarchy:

Architect/Engineer to GC

Architect issues "For Construction" transmittals to release drawing sets. GC acknowledges receipt (signs the transmittal). Example: "Architectural drawings, revision 2, for construction of 123 Main Street, released March 1."

GC to Subcontractors

GC distributes drawings to subs (framing, electrical, plumbing, etc.). GC prepares a transmittal listing which sheets were sent. Subs return a signed copy acknowledging receipt. This protects the GC: "We provided you the drawings, as documented by your signed transmittal."

Architect to Owner/Lender

Architect sends submittals to owner and lender "For Review" (if required by contract). These are often early coordinations before the GC release.

Revised Drawings

During construction, revised sheets are issued via transmittal. Example: "Addendum 1: Revised plumbing sheet P2 due to field change." Only the revised sheet is listed on the transmittal, not the entire set. But the revision date or number must be clear.

Transmittal Format and Key Information

Transmittals follow a standard format. Here's what must be included:

Header Section

Transmittal Number: Sequential (T-001, T-002, etc.) for tracking
Date: Date issued
Project: Project name and address
From: Sender's name, title, company, signature
To: Recipient's name, company, address, phone

Drawing List (Table)

Each drawing included in the transmittal is listed in a table with:

Sheet Number: A1, A2, S1, P1, etc.
Sheet Title: Cover Sheet, Foundation Plan, Electrical Plan, etc.
Revision Number/Date: Rev 1, or March 1, 2024
Quantity: How many copies sent (usually 1 per recipient, but can be more)

Purpose and Notes

Purpose Code: For Construction / For Review / For Record / For Coordination (checked or selected)
Notes: Any special instructions. Example: "Rev 2 replaces Rev 1. Discard Rev 1." or "Plumbing drawings superseded by Addendum 1."

Signature Block

Recipient Signature and Date: Proves the recipient got the drawings on that date
Comments: Optional space for recipient to note any missing pages or concerns

How to Acknowledge Receipt and Manage the Log

Once you receive a transmittal, you must manage it:

Check Receipt Immediately

Count the pages. Verify all sheets listed are included. If anything is missing, note it on the transmittal and return it for correction before proceeding with the drawings.

Sign and Return

Sign the receipt block (name, title, date). Return a copy to the sender (or keep on file if digital). This is your proof that you received it. If a dispute arises later, you have documentation.

Log It

Keep a master transmittal log (spreadsheet or in Procore/Autodesk) with columns: Transmittal #, Date Received, Drawing List, Revision, Purpose, Sender, Your Signature, Date Signed. This is your master record.

Distribute to Your Team

If you're the GC, make copies or send digitally to each trade that needs the sheets. Require them to sign a receipt transmittal acknowledging they got their copy.

Handling Updated Drawings Without a Transmittal

Sometimes you receive updated drawings (via email, Dropbox, etc.) without an official transmittal. This is a problem. You don't have proof of what was sent, when, or which revision. Here's what to do:

Request an official transmittal immediately. Don't use the drawings until you have formal documentation. Email the sender: "We received updated electrical drawings via email on March 1. Please provide an official transmittal documenting the revision and purpose."
If the sender refuses: Create your own internal transmittal documenting what you received and when. Not as good as an official one, but better than nothing.
Don't rely on email dates. Email can be forwarded, resent, or lost. A signed transmittal is the only proof of official receipt.
Mark the drawings clearly: Write "RECEIVED [DATE], NO TRANSMITTAL" on the drawings so no one assumes they came through proper channels.

Superseded Drawings: How to Track Which Sets Are Void

As the project progresses, drawings get revised. Old versions must be marked void so no one builds from them accidentally. Here's the process:

Issue a New Transmittal with Superseding Notes

When revised drawings are issued, the transmittal must clearly state: "Revision 2 of sheet A1 supersedes Revision 1. Discard Revision 1." or "Addendum 1 replaces Architectural drawing A3 issued March 1."

Collect Old Drawings

Ask all trades to return or destroy old versions. This prevents anyone from accidentally building from an outdated set. Large projects often require a signed statement: "We have destroyed all copies of Drawing A1, Revision 1."

Update Your Master Set

Your office keeps a "master set" of current drawings. When revisions are issued, replace the old sheets. At project end, the master set becomes the as-built record.

Digital Transmittals (Procore, Autodesk) vs. Email

Many projects now use platforms like Procore or Autodesk Docs for document management. These platforms have built-in transmittal workflows. Advantages:

Automatic logging: Every distribution is logged with timestamps
Acknowledgment tracking: The platform records when each recipient views or downloads
Version control: Old versions are archived; no confusion about which is current
Audit trail: If a dispute arises, you have a complete record

Important: Email alone is not sufficient for official transmittals. If your project uses email for drawings, require printed transmittals to be signed and returned. Digital platforms are better.

Common Mistakes in Transmittal Management

Sending drawings without a transmittal. You have no proof of distribution. If a sub claims "I never got those drawings," you can't prove them wrong. Always use a transmittal.
Not specifying the purpose code. "For Construction" vs. "For Review" is the difference between authorization to build and a draft. Be explicit.
Not collecting signed receipts from subs. A sub can later claim "We didn't know about that revision." Signed receipts prevent this claim.
Losing track of which revision is current. Multiple versions of a drawing floating around leads to mistakes and RFIs. A clear transmittal log prevents this.
Not marking old drawings as void. Someone builds to an old plan because they didn't know a revision had been issued. This causes rework and claims.
Mixing official and unofficial distributions. If some subs get official transmittals and others get email, inconsistency causes disputes. Use one method for the whole project.
Not documenting transmittals in the project file. Years later, a dispute arises. You have no transmittal records. Keep digital copies or scans of all transmittals in the project folder.

Sample Transmittal Log Columns

Keep your transmittal log in a spreadsheet or Procore/Autodesk. Here are the essential columns:

T# (Transmittal #)	Date Issued	Drawings Included	Revision	Purpose	Recipient	Signed Receipt
T-001	Feb 1, 2024	A1–A10, S1–S5	Rev 1	For Construction	General Contractor	Yes, Feb 1
T-002	Mar 15, 2024	P2 (Plumbing Plan)	Rev 2	For Construction	Plumbing Sub	Yes, Mar 15
