How to close out a commercial construction job when you are the sub

Almost everything written about construction closeout is written for the general contractor. That makes sense: the GC owns the certificate of occupancy, the owner handover and the final billing on the prime contract.

None of that is your sequence. Yours is narrower, starts much earlier, and is worth the last five to ten percent of your contract value. Here is the sub-side version.

Your closeout starts the month your crew demobilizes

The GC’s closeout happens at the end of the job. Yours happens at the end of your scope — which on a twenty-month project might be month seven. Two consequences drive everything below.

The paperwork comes due months after the only people who can produce it have gone. As-built markups, nameplate data off installed equipment, photos of work now behind finished walls, a foreman who remembers which riser moved and why. None of it is recoverable in month twenty. All of it is cheap in month seven.

The money waits anyway. Finishing in month seven does not move your final payment to month eight. Most subcontracts tie it to a prime-contract milestone you have no part in, which is how a sub who demobilized in the spring is still unpaid at Christmas. When retainage is actually released works through the gates in order.

So closeout is two efforts: a field capture while the crew is still there, and an office campaign for months after.

At buyout: get the requirements, and price them

Ask for the closeout requirements the week you sign, not the week you finish. They live in the subcontract, the specifications, or a separate closeout manual — sometimes all three, and sometimes not agreeing. What you want in writing is the list: which documents, in what format, how many copies, through what portal, to whom.

Then do the thing most subs skip. Price it. Three bound operation and maintenance sets, as-builts drafted from field markups, two days of owner training and a crate of attic stock is real cost — drafting hours, printing, a technician’s time, material bought at the end with no markup left. Buried in your installation lines, it means working the last month for free.

Carry closeout as its own line on your schedule of values. It gives the work a value instead of letting the GC call it punch, and something to bill when the package lands.

Before the crew leaves: what only the field can produce

Put this on the foreman’s last two weeks.

• The as-built markups. The redlines are in pencil on the set in the gang box, and that set is the only record that the main got routed around the footing. Collect it, scan it, attach it to the job.
• Photos of concealed work before it is covered. This is the evidence your rough-in was right, and often the only defense against a charge raised a year later. The discipline that protects you against back charges produces your as-built record for free.
• Nameplate and serial data on everything you installed — model, serial, capacity, warranty start, photographed with the location. Later means lifting ceiling tiles in an occupied building.
• Test, inspection and start-up reports, signed by whoever ran the test, on the day they ran it.
• Attic stock delivered and receipted now. Afterwards means a one-off price, a delivery charge and chasing a signature.
• A punch walk with a foreman who built the work. The person who hung it closes a list in a day; a replacement crew needs a week.

Most of this lands naturally in a daily log, because the field is already filling one in. Photos, a dated narrative and the day’s labor are exactly the artifacts closeout needs, captured as a by-product of work the foreman does anyway.

Punch: split the list the day it arrives

Punch is the gate that moves slowest for the least money — the retainage article covers why. What is sub-specific is splitting the list as it arrives.

Your own defective or incomplete work is your cost. Damage by another trade, or work added after you were covered up, is billable — and only if you log it as it is found, with a photo, a date and the trade responsible. A T&M tag signed on site beats a list of grievances assembled at closeout.

Assemble the package at seventy-five percent

Open the package when the job hits seventy-five percent. Everything on it is cheaper to produce while people still answer the phone. The retainage article lists the usual contents — as-builts, O&M manuals, warranty letters, test and inspection reports, owner training, attic stock, certified payroll. Three items catch subs out and are worth naming:

• Consent of surety, on a bonded job. It comes from your bond agent, not from you, and it takes days nobody budgeted. No GC releases final payment without it.
• Final waivers from your suppliers and lower-tier subs, not only from you. You are collecting signatures from companies that have already been paid and have no reason to hurry.
• Nameplate and serial data as a deliverable, in whatever schedule or spreadsheet format the building operator’s maintenance system wants — not just the photos your foreman took. This is the line item that is genuinely unrecoverable once the ceilings are closed.

Two notes decide whether it gets accepted. Every line needs a name and a date, not a checkbox — as-builts to a drafter, O&Ms to a project engineer, training to a technician, waivers to the office. An unowned line is the line that holds the job. And packages get rejected on format, not content: wrong copy count, unmerged PDFs, no cover sheet, wrong portal folder.

The final billing is three events, not one

One: bill the remaining contract to complete. Every SOV line to one hundred percent, including every approved change order. If an approved CO never made it onto the schedule of values, this is where you find out — the hardest possible moment to fix it.

Two: reconcile against the GC’s certified numbers before you submit. Your billed-to-date and theirs diverge the moment a change order lands on one side only, and at the final draw there is no next month to catch it in.

Three: bill the retainage release as its own event. It is not new revenue. It is money you already earned and billed, and treating it as fresh billing is how a job reports revenue past its own contract value.

A fourth decision hides inside the first. Anything still in an unapproved change order at the final draw is a claim, not a billing line. Decide deliberately — pursue or write off — then record which and who chose it, because in six months somebody will ask.

Then the waiting part

The waivers have an order that matters: the conditional final waiver gets you the final payment, and the unconditional one is signed after the money arrives. Lien waiver tracking in Texas covers how the four forms differ.

Your preliminary-notice and lien-filing windows run on statute, not on the GC’s schedule, and on a closed job that clock keeps running while nobody in the office is watching it. Put those dates in the same calendar as the closeout tasks. Nothing here is legal advice, and a deadline question belongs with a construction attorney in your state.

Close the job in your own records too

Run a final cost review while the job is fresh. Budget against actual, by cost type and phase. This is the only moment you learn anything from the job — what labor really ran per unit, which change orders were priced short. That number is next year’s bid.

Then archive it so a claim can be defended out of it. Warranty runs a year or more past completion and disputes arrive later still. The file needs the signed change orders, the T&M tags, the daily logs, the draws as submitted and as certified, and the waivers as executed. A workbook on a departed PM’s drive is not an archive.

The sequence, in order

1. At buyout: requirements in writing, priced as an SOV line.
2. At seventy-five percent: open the package, owner and date on every line.
3. Before demobilization: markups, concealed-work photos, nameplate data, signed test reports, attic stock receipted.
4. Walk punch with the foreman who built it, close it, get written acceptance — and log by-others work as a signed ticket.
5. Submit the package in the required format, and confirm acceptance.
6. Reconcile billed-to-date against the GC’s certified numbers, then bill to complete.
7. Decide on the record what happens to the unapproved change orders.
8. Conditional final waiver out, payment in, then the unconditional one.
9. Bill the retainage release as a release. Then final cost review, and archive.

How SubMark handles the operational parts

Most of closeout is discipline, not software. SubMark holds the parts that are records:

• One schedule of values per job, locked when the first draw is submitted, with approved change orders added automatically — so “is every CO on the SOV” is answerable at the final draw instead of arguable.
• Drawn, certified and received stay three separate numbers on every draw, which makes the final reconciliation a comparison rather than an investigation.
• Retainage recorded per draw in dollars, totaled across every job and GC including finished ones, with the final retainage billing flagged as a release.
• Lien waiver tracking with a status on every waiver you issue — drafted, signed, sent, received — and the executed copy on the record, so at the final draw you can tell a cleared waiver from one still sitting in a drafts folder. SubMark does not produce the forms, and the waivers you chase from suppliers live outside it.
• Submittals build packages from a material library with cover sheets and a merged PDF export — the same machinery a closeout package needs.
• Daily logs with photos, plus job files for the reports, so concealed-work evidence is captured on the day. Job costing holds budget against actual by cost type and phase: the final cost review, without the spreadsheet.

Honest limits: no closeout-package checklist module, so the document list is yours to keep. Daily-log uploads are images, so a full test report goes in the job’s files. No statutory notice or lien deadlines. And the punch-and-patch surface ships with the drywall pack, so an electrical job has no such tab.

There are dedicated pages for draw tracking, retainage tracking and lien waiver tracking. Office staff are what you pay for and field users are free and unlimited, which matters when the useful closeout work is done by foremen — see how pricing works.

Your closeout is not the GC’s. It starts the day your crew demobilizes, and the documents that decide whether you get paid are produced by people about to leave.
