What is a transmittal?
A transmittal is the formal, recorded issue of controlled drawings or documents to another party, sent with a cover sheet that lists every file and its revision. It gives both sides a dated record of what was sent, to whom, and when.
Engineering and construction teams use transmittals to send controlled documents to external companies, contractors, and vendors, so a document leaves the register through a tracked, repeatable process rather than a loose email.
Also called document transmittal · Part of the document control record · Related term: submittal package
A transmittal is a process, not a single file.
Every transmittal has four parts, and each one is there so the issue can be traced back later. For an asset owner, transmittals are common practice when preparing a tender on a capital works project.
The owner sends a comprehensive package of documents for review, so prospective vendors can prepare accurate quotes, and the clear, transparent record supports a fair vendor selection.

Lunr keeps the transmittal on the record.
Issue a transmittal covering a set of documents at their current revision, and Lunr records the recipient, the date issued, and the revision of each document sent. When someone asks whether a contractor had the current drawing, the answer is on the transmittal, not in a sent-items folder.

Questions about transmittals.
- What goes on a transmittal cover sheet?
- The cover sheet lists every file in the package with its revision number, names the recipients, and states the reason the documents are being sent, such as For Information or For Change. It is the record of exactly what was issued, so a reader can check what they received against what was meant to arrive.
- Why do asset owners use transmittals?
- For an asset owner, transmittals are common practice when preparing a tender on a capital works project. The owner sends a comprehensive package of documents for review so prospective vendors can prepare accurate quotes, and the clear, transparent record supports a fair vendor selection.
- Does Lunr record who received a transmittal?
- Yes. Issue a transmittal in Lunr and it records the recipient, the date issued, and the revision of each document sent, and the transmittal stays on the record. Lunr can send a package to one or more contacts without granting them access to the document repository, so who received what, and when, is a lookup rather than a search through sent email.
