This free construction project closeout checklist is for main contractors, principal contractors, project managers and commercial teams, and for client-side project managers who need to see what is still owed. One run closes one project, from the closeout plan weeks before completion to the end of the defects period. It covers the punch list, testing and commissioning, certificates, O&M manuals, as-built drawings, warranties, spares, training, and keys and access, then the project director’s confirmation that practical or substantial completion has been certified. After completion come demobilisation, the final account, lessons learned, the end of defects inspection and the archive. Choose UK or US rules and the matching steps appear: the health and safety file, the fire safety information and the building control notices, or the certificate of occupancy and lien waivers. Retention release and funder reporting steps appear only when they apply.
On a construction project, practical or substantial completion is the moment the contract says the building is finished enough for the client to take it over. Closeout is the work either side of that date: proving the building is finished, giving the client what it needs to run it, then settling the money and the defects. Most of it is paperwork owed by subcontractors who are about to leave site, which is why it slips.
This checklist is narrower than the project closeout checklist, which closes any kind of project, and it takes over where the construction and commissioning phases of the capital project checklist end. It does not replace your punch list: the walk-through and its items get their own list, and this checklist makes sure that list is closed before the completion inspection. At the other end of the job, the construction site induction checklist brings each worker onto site; this one takes the site away.
Covers: the punch list, testing and commissioning, certificates, O&M manuals, as-built drawings and warranties.
Owned by: the project manager and site manager, with every subcontractor.
Output: a building the client’s representative can certify.
Covers: training, spares and attic stock, keys and codes, the fire safety information and health and safety file in the UK, the certificate of occupancy in the US.
Owned by: the project manager, with the client’s facilities team.
Output: certified completion and a building someone can operate.
Covers: demobilisation, final accounts, retention, lien waivers in the US, lessons learned, the defects period and the archive.
Owned by: the commercial lead and the project director.
Output: an agreed final account, released retention and a closed project.
Eight phases take one project from the closeout plan to the end of the defects period. Choose UK or US rules on the first task and the matching legal steps appear. The retention, funder and lien waiver tasks appear only when they apply, and nothing after the project director’s confirmation of completion can be completed until it is given.
Start closeout weeks before the planned completion date, while the people who know where everything is are still on site. Set the completion date first, because every due date counts from it, and answer the three questions that decide which steps appear.
The punch list, or snagging list, is the work still to finish or put right. Close it before the completion inspection, so the client’s representative inspects a finished building rather than a list.
Commissioning shows each system works as designed before anyone relies on it. The certificate tasks follow the rules chosen in Phase 1: building control notices in the UK, the certificate of occupancy in the US.
This is what the client needs to run, maintain and later alter the building. Collect it from subcontractors early: it is much harder to get once they have left site.
The last task is the gate. Nothing after it can be completed until the project director confirms that completion has been certified under the contract.
The building is now the client’s. Leave the site as the contract and any agreements with neighbours require, and keep a dated record of how you left it.
Agree the money while the records are fresh. The retention, funder and lien waiver tasks appear only when Phase 1 says they apply.
The defects period runs from the certified completion date for as long as the contract says. The due dates here assume twelve months; change the offsets in your copy of the template if your contract sets a different period.
Completion is a contract event in both countries, but much of the paperwork around it is set by law. The table shows what the law asks for at closeout in England and in the US, and which regulation says so. Wales has its own version of several of the Building Regulations, and US requirements differ by state and city, so check the rules for the site before you rely on the table.
| At closeout | England (UK) | United States |
|---|---|---|
| Completion itself | Defined and certified under the building contract. Practical completion is the usual UK term. | Defined and certified under the contract. Substantial completion is the usual US term. |
| Building approval | A completion notice to building control within five days of completion, with signed statements from the client, principal contractor and principal designer. The authority has eight weeks to give a completion certificate if it is satisfied (Building Regulations 2010, regs 16(4) and 17). | Final inspections and a certificate of occupancy under state and local codes. In New York City, for example, no one may legally occupy a building before a certificate or temporary certificate is issued. |
| Tests and commissioning | Air pressure test results to building control within seven days of the final test, and a notice that the fixed building services are commissioned (regs 43 and 44). | Follow the contract, the specification and the inspections the local code official asks for. |
| Fire safety information | Given to the responsible person by completion or first occupation, acknowledged, and building control told within five days (reg 38). | Follow the contract and the fire code that applies locally. |
| Health and safety file | Prepared by the principal designer with information from the principal contractor, passed to the client at the end of a project with more than one contractor, and kept normally for the lifetime of the building (CDM 2015 reg 12; HSE L153). | No OSHA equivalent. The O&M manuals and as-built drawings the contract asks for carry much of the same information. |
| Energy | The energy performance certificate to the owner, with notice to the local authority, within five days of completing a new building (EPB Regulations 2012 reg 7A), and information on running the fixed building services efficiently (reg 40). | Follow the contract and the energy code that applies locally. |
| Final payment | A payment notice for every payment the contract provides for, within five days of the due date, so retention releases and the final payment need one too (Construction Act, s.110A). | Final payment is usually exchanged for final lien waivers or releases. Lien rights and the wording of waivers are set by state law. |
Retention, defects periods and the test for completion are contract terms. The standard forms used in the UK and the US each set them in their own way, and bespoke amendments change them again, so read your own contract rather than relying on what the last job said. Record the defects period and the retention terms in Phase 1, and the due dates for the end of defects inspection and the retention release follow from the completion date.
Records outlive the project. In the UK, the client keeps the health and safety file for as long as it is relevant and passes it on if they dispose of their interest in the building. In the US, OSHA’s recordkeeping rule asks for a separate injury and illness log for a site expected to operate for a year or longer, kept for five years after the end of the calendar year it covers (29 CFR 1904.30 and 1904.33). Set a retention period for the rest of the project file when you archive it.
The project director’s confirmation is assigned to them alone, and the checklist halts there. Demobilisation, the final account and the defects period cannot be completed until completion has been certified and recorded, with the certificate attached. See how approvals that halt a checklist work.
Due dates count back from the planned completion date and forward from it, so moving the date moves the whole closeout. Registers for subcontractor documents, commissioning, warranties, training and spares sit on the tasks they belong to, and the Reports Grid shows every project in closeout as tasks are completed.
The end of defects inspection, the making good and the retention release fall due a year after completion and are assigned from the first task, so nobody has to remember them. Choose UK or US rules and the matching notices and certificates appear. Change the offsets to suit your contract in the template designer.
CheckFlow does not certify completion and it is not a document management system. It runs the closeout steps in the same order on every project, with a record of who did what and when, and keeps the certificates and registers on the tasks they belong to.
This template closes one construction project. Close other kinds of project with the Project Closeout Checklist, run an investment from feasibility to handover with the Capital Project Checklist and induct every worker with the Construction Site Induction Checklist. After handover, the facilities team can run the plant from the O&M manuals with the Preventive Maintenance Checklist and use the fire safety information in the Fire Risk Assessment Checklist, and a building that will be let can have its condition recorded with the Move-In / Move-Out Inspection Checklist.

The closeout plan and who owns each deliverable, the punch list closed, testing and commissioning records, the certificates and approvals the site needs, O&M manuals, as-built drawings, warranties, spare parts and attic stock, training for the client’s facilities team, and keys and access codes. In the UK add the health and safety file and the fire safety information; in the US, the certificate of occupancy and lien waivers. After completion come demobilisation, the final account, retention, lessons learned, the defects period and its end inspection, and archiving the records.
They are the UK and US names for much the same contract event: the point at which the building is finished enough for the client to take it over and use it, even if minor items remain. Each contract sets its own test and says who certifies it, often the architect, contract administrator or owner’s representative. The certified date matters, because it usually starts the defects or correction period and can trigger a retention release, so record it exactly and keep the certificate.
Under the UK’s CDM 2015, it is the information needed to work safely on the building in future: maintenance, cleaning, refurbishment or demolition. It is needed on a project with more than one contractor. The principal designer prepares and updates it, the principal contractor supplies information for it, and at the end of the project the principal designer, or the principal contractor where there is none, passes it to the client. HSE’s guidance says the client keeps it for as long as it is relevant, normally the lifetime of the building.
Operation and maintenance manuals, as-built drawings, test and commissioning certificates, warranties and guarantees, a register of keys and access codes, a list of spares and attic stock, training records and the completion certificate or written confirmation under the contract. In England the responsible person also receives the fire safety information and the owner an energy performance certificate, and the health and safety file goes to the client under CDM 2015. In the US the certificate of occupancy and the final lien waivers are usually part of the set.
When the contract says. Where retention is split, part is released at practical or substantial completion and the rest once the defects or correction period has ended and the defects are made good. The percentages and triggers are contract terms, so read them at the start of closeout and put both dates in the diary. In England, Wales and Scotland, the Construction Act requires a payment notice for every payment a construction contract provides for, so each release needs one.
In the US, a lien waiver or release is a document in which a contractor, subcontractor or supplier gives up its right to claim a lien on the property for the amount it has been paid. Owners and general contractors usually ask for one with each payment, and a final waiver with the final payment, so the property is clear of lien claims when the project closes. Lien rights and the wording of waivers are set by state law, so use the form the state and the contract require.
Weeks before the planned completion date, not after it. Subcontractors owe most of the closeout documents, and they are hardest to reach once they have left site. Start the checklist when the end of the programme is in sight: set the planned completion date, send every subcontractor its list of documents, walk the works for the punch list and book the commissioning and training. The tasks after completion, from demobilisation to the end of the defects period, then fall due from the same date.
