Commissioning and Closeout for Tilt Wall Projects

Roof on is not done. A tilt wall building can look finished from the road weeks before it can legally be occupied, and the last stretch of the job decides whether the owner opens on time. Fire pumps must flow, dock levelers must cycle, the roof must hold water out, the slab must be measured against its flatness spec and the state's accessibility review must be signed off. Every one of those has a person who has to witness it and a document that proves it.

We plan closeout from the beginning. The test list is written at the same time as the schedule, the inspectors are booked as the work reaches them and the records are collected as we go. Waiting until the end to find the paperwork is how an owner ends up paying carrying costs on a finished building.

This page lays out what we test, what we deliver and how we hand a tilt wall building to the owner.

We commission by system, in the order the building comes online. Power first, then fire water, then life safety, then dock equipment, then mechanical, then the building envelope checks. Each system gets a test sheet with the date, the witness and the result. If a system fails, we fix and retest it before the next system depends on it. A sprinkler test that waits for the last day is a day that cannot be recovered.

The envelope gets its own check. Panel joints and sealants are inspected, roof drains are tested, and a water test on openings and canopies is done where the architect calls for it. For insulated and cold buildings, the envelope check includes a pressure or thermal test. We invite the owner's facilities team to walk the building with us before turnover so they see how it is meant to operate.

The slab gets measured, not eyeballed. Where the specification sets a flatness and levelness number, a technician runs the profile readings within the window the spec allows and we give the results to the owner and the racking vendor. If an area falls short, we discuss grinding or topping options with the engineer before the tenant's equipment is ordered. The dock equipment is cycled at every position with a loaded and unloaded check, and we log the leveler range, the door operation and the seal fit so the first trailer backs into a dock that works.

The package contains as-built drawings, panel and embed records, the special inspection reports, concrete test results, slab flatness and levelness readings, roofing and wall warranties, operations manuals for dock equipment, doors and mechanical gear, the fire alarm and sprinkler acceptance records and the certificate of occupancy. We organize them in a digital binder with a table of contents. Warranty start dates are listed so the owner can track them.

We also deliver the small items that become big at the first tenant meeting: keys and keying schedules, attic stock of paint and sealant, spare parts, door hardware schedules and a list of the manufacturers' contacts. Training sessions are scheduled for the owner's team for anything that needs it. A short orientation walk for the first tenant's operations manager covers the panic hardware, the roof access, the fire riser room and the location of the main electrical disconnects, which saves a surprising number of service calls in the first month. Our super-flat warehouse floors records, for example, include the readings that a racking supplier or an automated storage vendor will ask to see.

A distribution warehouse closes out with the dock equipment, fire protection and slab records at the center. A cold storage facility adds refrigeration commissioning and the temperature pull-down. An office or medical building adds accessibility and mechanical balancing. A data center shell adds power and cooling commissioning led by the owner's team, and we coordinate our work to theirs.

Large logistics facilities show how much is at stake. El Paso's airport air cargo complex totals 288,000 square feet in two 144,000-square-foot buildings, with over 34 acres of aircraft parking, on a $60 million investment. DFW handled 858,952.3 tons of cargo in 2025. In Corpus Christi, the ship channel was deepened from 47 to 54 feet and marked complete in 2025. Facilities in those flows are valuable every day they are open, so a late certificate of occupancy has a real cost.

The final inspection sequence usually includes the building, fire, health when relevant and accessibility. Projects of $50,000 or more in Texas are registered with the state accessibility program, and a registered inspector checks the finished work. The city issues its certificate of occupancy only after the required inspections pass and the fire marshal signs off.

We keep a punch list from the start and close it out weekly instead of in the last week. The architect and owner walk the building with us twice before the final inspections, once at substantial completion and once for the final punch. Our permitting and inspections team coordinates the inspectors and the paperwork.

Closeout is not the end of the relationship. We stay available for warranty items, and we walk the building again before the first year ends to look for slab cracks, sealant failures and roof problems. Early repairs are cheap, and owners tell us they appreciate the second look. Industrial developers and REITs often ask for a condition report to give to the first tenant.

If the building will be expanded or finished for tenants, the records help: the panel layout, the embed locations and the slab thickness save time when a future tilt wall renovation and tenant finish project begins.

Share the building type and the target occupancy date. We will provide a test list, an inspection calendar and a records plan you can attach to your lease or loan documents.

What is in a closeout binder?

As-built drawings, inspection and test reports, warranties, manuals, certificates and contact lists. It is organized by system so the owner's team can find what they need.

When do warranties start?

Usually at substantial completion, though some start at equipment startup. We list each start date and each term so the owner can track them.

How do you test the fire system?

The fire protection contractor flushes the lines, pressure tests the piping and flows the pump. The fire marshal witnesses the acceptance test. We schedule it early because a failure can take days to correct.

Can the owner occupy before everything is done?

Sometimes, with a temporary certificate of occupancy. It depends on the city and on whether life-safety items are complete.

What happens if a defect appears later?

Report it, and we respond under the warranty. We also schedule a walk before the first anniversary to find issues early.
