Build the sheet list from the transmittal
Start with the drawing transmittal or the sheet index in the set, not with the files that happen to be in the folder. Copy every sheet number into a list and group it by discipline. Include the general, architectural, structural, civil, mechanical, electrical, and plumbing sheets even if the package does not use all of them.
The list should describe the set that was issued, not the subset that was convenient to open. Record the revision and issue date beside each sheet number. A complete count of the wrong revision is not a complete takeoff.
Mark any sheet that arrived in a later addendum and give it its own line. The quantity surveyor page describes the takeoff support this closeout protects, and the drawing log guide shows how to keep the revision history beside the count. The AACE recommended practices treat a documented estimate basis as part of the estimate, and the sheet list is part of that basis.
Count what is open, not what was sent
Walk the open files and tick each sheet number against the list. Do not assume the folder is complete because the transmittal says so. Files get renamed, moved to a subfolder, or left in an email attachment.
The count should reflect what the takeoff team actually used. A sheet that was never opened is a risk even when it exists. Mark each sheet as counted, not applicable, or missing.
A civil sheet may not carry building quantities, but it still belongs in the list and deserves a status. That distinction prevents a reviewer from treating an unmarked sheet as checked. It also shows whether the missing sheet matters to the scope.
Check the sheet number sequence for gaps before accepting the list. A set that runs from A101 to A110 but skips A104 may have a missing sheet or a numbering choice that the designer can explain. Either way, the gap deserves a note.
Sequence gaps are one of the fastest ways to find a document that never reached the takeoff team. Compare the sheet count with the takeoff tags. Every quantity should point to a sheet that appears on the list.
If a tag points to a sheet that is missing or superseded, the quantity is not closed. The comparison is the real closeout test, because a sheet count alone does not prove the quantities were taken from it.
Explain every exception
Write a short reason for each missing or excluded sheet. A foundation sheet may be missing because the scope starts at the slab, which is a valid exclusion. A structural sheet may be missing because it was issued after the takeoff window, which is a schedule problem.
The reason should let a reviewer decide whether the exception is acceptable. Assign an owner and a due date to every missing sheet. A note without an owner becomes a permanent open item.
If the sheet is not needed, close it with a reason instead of leaving it open. The closeout should end with a short list of open items, not a long list of unexplained blanks. Check whether the missing sheet affects a bid alternate or an allowance.
Those lines are often priced from a separate sheet that the base takeoff never touches. A missing alternate sheet can survive a base scope count and still change the bid. Add the alternate sheets to the list even when the base estimate is already complete.
Sign the closeout
Record the person who ran the count, the date, the set revision, and the number of sheets checked. Add the count of open items and the name of the person who accepted them. A signature is not ceremony, because it gives the next reviewer a name to call when a sheet is disputed.
Keep the record with the takeoff, not in a separate email. If the count happens late, say so in the record. A closeout run after the estimate was assembled is better than none, but it does not protect the numbers already released.
The note should distinguish a pre-release check from a post-release audit. That honesty helps the team fix the process instead of hiding the timing. Give the count a clear end state so it does not stay open forever.
The end state is a complete sheet list, a status for every row, and an accepted disposition for each exception. Once those three items exist, the closeout can be filed.
A count that never reaches an end state becomes another unfinished task on the bid list. The end state should be written in the template so the team knows when to stop.
Use the count on the next bid
Keep the sheet list as a template for the next project of the same type. The discipline groups and the status columns rarely change, even when the sheet numbers do. A reusable template makes the closeout faster and less likely to skip a category.
It also gives a new team member a clear starting point. At the end of the bid, note which sheet caused the most rework. Maybe a revision was missed, or a discipline was never assigned.
Add that lesson to the next template and remove any step that added no value. Over time, the sheet count becomes a reliable closing habit rather than a last-minute scramble.
| Field | What to record | Why it matters |
|---|---|---|
| Sheet number | Full number from the transmittal | Matches the issued set |
| Revision and date | Current issue and received date | Prevents a stale count |
| Status | Counted, not applicable, or missing | Shows what is actually closed |
| Owner and due date | Person resolving a missing sheet | Turns a gap into an action |
