Construction closeout documents: what subs owe at turnover

At the end of a commercial job, the building is only half the deliverable. The other half is paper: the warranties, manuals, drawings and certificates the owner needs to run and maintain what you built. Most of it comes from your subcontractors, and the owner's acceptance of the package often stands between you and your retainage.

This guide lists the construction closeout documents a general contractor typically collects, explains where the requirements come from on your project, and covers how to get them in without spending the last month of the job writing reminder emails.

Where the list comes from

Before you build a list from memory, read the project's own requirements. On most commercial jobs they live in three places:

• Division 01 of the specifications. Projects that follow the CSI MasterFormat layout usually have a closeout procedures section (01 77 00) and a closeout submittals section (01 78 00), with subsections for operation and maintenance data, warranties and project record documents. These say what format the owner wants, how many copies, and when.
• Each technical section. The roofing section says which roof warranty is required and for how long. The mechanical sections say which equipment needs O&M data, which systems need testing and balancing, and what attic stock to leave. Look for a "closeout submittals" or "maintenance materials" article near the end of each section.
• The contract. The owner-contractor agreement and general conditions set what has to happen for final payment and the release of retainage. Your subcontracts should pass the same obligations down to each sub.

Requirements vary by owner, by project and sometimes by state. Treat the list below as a starting point to check against your spec, not a substitute for it.

The documents, by type

Warranties

Expect two kinds for many trades:

• Manufacturer warranties cover a product or system, such as a roof membrane, a storefront system, a rooftop unit or a water heater. Some, like a roofing manufacturer's no-dollar-limit warranty, require the manufacturer to inspect the installation before they issue it.
• Installer or workmanship warranties come from the sub itself, usually as a letter on its letterhead covering its labor for a stated period. Our guide to warranty letters in construction covers what one contains.

For each warranty, the owner will want the start date, the term and the end date. Many start at substantial completion rather than on the day of installation, so record which.

Operation and maintenance manuals

O&M manuals describe how to run, service and repair installed equipment: product data, maintenance schedules, parts lists, wiring diagrams and service contacts. Mechanical, electrical, plumbing, fire protection and fire alarm trades owe the bulk of them. They are often large PDF files, and they are one of the slowest items to arrive. See O&M manuals in construction for what a complete one includes.

As-built drawings

As-builts, or record drawings, show what was actually installed where it differs from the design: rerouted ductwork, moved panels, added valves, changed riser locations. Each trade marks up its own work. The spec says whether the owner wants marked-up prints, PDFs or CAD files.

Test reports and certificates

These prove that systems were tested and passed. Typical examples:

• test and balance report for HVAC;
• sprinkler hydrostatic test certificate and the contractor's material and test certificate;
• fire alarm acceptance test report;
• domestic water disinfection report and backflow preventer test report;
• insulation resistance (megger) test results and lighting controls commissioning reports;
• low-voltage cabling certification results.

Owner training records

Where the spec requires it, a sub demonstrates its systems to the owner's maintenance staff and turns in a sign-in sheet or training record.

Attic stock and spare parts

Extra materials the owner keeps for repairs: ceiling tile, flooring, paint, spare sprinkler heads and the wrench, filters and belts, lamps. The document is the receipt or transmittal showing what was delivered and where it was left.

Final lien waivers and payment paperwork

Many owners require final lien waivers from subs and suppliers before final payment. Waiver forms and their effect are set by state law in many states, so follow your contract and your attorney's guidance on which forms to collect. A closeout list should still track whether each sub's waiver is in.

A simple tracking layout

If you are building the list in a spreadsheet, one row per item per sub works better than one row per sub. Useful columns:

One row per item lets you see exactly what a sub still owes, and it gives you the index for the turnover package for free.

Getting them in

The documents are rarely hard to produce. They are hard to collect because every sub has moved on to its next job by the time you ask. A few habits help:

1. Ask early. Send each sub its list well before substantial completion, not after. Manufacturer warranties and O&M manuals can take weeks.
2. Ask each sub only for what it owes. A long generic list gets skimmed. A short list with the sub's own items gets answered.
3. Make it easy to send. Subs will not log in to a portal they use once a year. A link they can upload to, or a clear email address, works better.
4. Follow up on a schedule. Weekly before substantial completion, and more often after it. Copy the project manager so the sub knows it matters.
5. Know when to call. After several unanswered reminders, a phone call from the PM usually does what another email will not.

Where Closeout Chase fits

Closeout Chase is built for the collecting. You create the project, add its subs, and each trade starts from a standard closeout checklist that you edit to match your spec. Each sub gets one link, with no login, listing only the items it owes. Reminders go out weekly, then every 3 days after substantial completion, with you copied, until every item is in; a sub that lets 12 in a row go by without answering is flagged in your Monday digest so you can call. When you are ready, it builds a turnover ZIP with a folder per trade, an index PDF that lists every item and its status, and a warranty register CSV.

It collects, files and indexes the documents. It does not judge whether a warranty or test report meets your spec; you review the package before it goes to the owner.
