Construction closeout without the last-month scramble

The two milestones

• Substantial completion: the owner can use the work for its intended purpose, with a punch list of small items still open. On many contracts, warranties start and liquidated damages stop here.
• Final completion: the punch list is done, every closeout document is delivered, and final payment is due.

Contracts define both in their own words. Substantial completion and punch lists covers what changes on the first date.

Start at the halfway point

Most closeout documents can be gathered while the work is going on. Put a closeout log in place when the job is about half built, with a line for each item, the sub responsible and the date due:

• Record drawings, marked up as work is installed, not reconstructed at the end.
• Operation and maintenance manuals for each piece of equipment, collected with the reviewed submittals.
• Warranties, in the form and length the specifications call for, from each sub and manufacturer.
• Attic stock and spare parts the specifications require.
• Testing and commissioning reports, such as balancing reports and system tests.
• Owner training, scheduled and signed off.
• Inspection sign-offs and the certificate of occupancy, where the building department requires them.

Run the punch list fast

• Walk each area with your own list before asking for the architect's inspection.
• Give each item to one sub, with a date.
• Back-check items as they are closed, with a photo.
• Keep new owner requests off the punch list. New scope is a change order.

Follow the money

A worked example with invented numbers. Contract sum $3,200,000, retainage 5%, all work billed.

• Retainage held: 3,200,000 x 0.05 = $160,000
• At substantial completion, the contract lets the owner keep 1.5 times the value of the open punch list and release the rest. The punch list is valued at $40,000.
• Kept back: 40,000 x 1.5 = $60,000
• Released at substantial completion: 160,000 - 60,000 = $100,000

Check: 100,000 + 60,000 = 160,000, and 60,000 / 40,000 = 1.5.

The last $60,000 comes with final payment, once the punch list and closeout documents are done. The 1.5 multiple is invented for this example. Contracts and, on some public work, state laws set their own terms; see retainage.

What a slow finish costs. The job's profit is $160,000, 5% of the contract. If the remaining $60,000 arrives four months late and the contractor's credit line costs 9% a year, the interest is 60,000 x 0.09 x 4 / 12 = $1,800. Check: 60,000 x 0.09 = 5,400 a year, and 5,400 / 3 = 1,800 for a third of a year. Add the superintendent's and project manager's time on return visits, and a slow closeout eats real profit.

If substantial completion itself was late, liquidated damages may be deducted from this same retainage.

The final payment package

Owners usually want, with the final application:

• the final pay application, with the schedule of values at 100% and every change order included
• final lien waivers from the contractor and, as the contract requires, from subs and suppliers. Unconditional final waivers are usually given only once payment is received; see lien waivers.
• the surety's consent to final payment, on bonded jobs
• every closeout document on the log
• an affidavit that bills for labor and materials have been paid, where the contract asks for one

After final payment

Warranty work continues for the warranty period. Keep the job file, including daily reports, the SWPPP records if there was a stormwater permit, and safety records, for as long as your contracts, the law and your insurer require. A claim can arrive years later.

FAQ

What is the difference between substantial and final completion?

At substantial completion the owner can use the work, with a punch list still open. At final completion everything, including the paperwork, is done.

When should closeout start?

As early as possible. Record drawings, manuals and warranties can be collected while the work is going on.

What usually holds up final payment?

Open punch items, missing closeout documents, missing lien waivers and, on bonded jobs, the surety's consent.
