Commissioning, Turnover and Closeout for Industrial Buildings

Substantial completion is a date on a contract; turnover is the day your night shift can run the building without calling us. We plan the gap between those two events from the beginning, because it is where industrial projects most often lose weeks. A dock leveler that has not been tested, a fire pump that has not been flowed or a switchboard whose settings have not been verified can hold up a certificate of occupancy long after the last wall is painted.

Our commissioning and closeout process begins during design. We write a commissioning plan listing every system, the test that proves it, who witnesses it, what documents result and when it is scheduled. The plan is attached to the master schedule so that testing windows are planned the way pours and inspections are.

By the time your operations team arrives, they have already been through the building with us, and they know where every valve, panel and shutoff lives.

Systems we test and prove

The commissioning scope covers electrical distribution, lighting and controls, mechanical and refrigeration systems, fire alarm and sprinklers, the fire pump and hydrant flow, dock equipment, overhead doors, compressed air or process utilities, and building automation. Each gets a pre-functional check, a functional test and a performance test, with results recorded. Where a system serves both the new building and an existing one, we also test the interface between them, since that seam is where a problem usually hides. Test sheets carry the date, the witness, the instrument used and the pass or fail result, and they are signed on the spot rather than reconstructed later.

For dock-heavy buildings we test every door, leveler, seal and restraint, not a sample, and log the result by position number. A 60-door warehouse has 60 chances for a single mismatch to cost a loading day. We tie this directly to fire-water loop and hydrant acceptance, since the fire marshal's witness test is often the last gate before occupancy.

Editions, listings and sign-offs

Closeout documentation reflects the codes the building was permitted under. Aurora lists the 2023 National Electrical Code with its 2021 I-codes, so electrical gear, labeling and arc-flash documentation should follow it. Brighton plans to move to the 2024 I-codes when the state adopts the 2026 NEC, which shows how editions shift across neighboring jurisdictions even within a few years.

Colorado sets electrical and plumbing editions at the state level while building codes are set locally, and the 2026 National Electrical Code takes effect statewide on January 1, 2027. A building permitted just before that date and a building permitted just after may therefore close out under different electrical requirements. We note the governing edition in the closeout binder so your maintenance staff and future inspectors know which one applies. For a building in the city, our Aurora notes explain how that edition is applied locally.

Testing as a schedule, not a surprise

We test in layers. Components get factory and field checks first, then subsystems, then integrated systems. Integrated tests, such as a simulated power failure with generator pickup, fire alarm interface with door releases and dock lighting, are scheduled when everything below them has passed. That order lets us find problems while the cause is still easy to reach.

Punch lists run in parallel with commissioning rather than after it. We walk each area with your representatives when it is about 90 percent complete, record deficiencies in a shared log and close them as the area finishes. A single walk at the end of a project is slow and tends to become a negotiation; a rolling punch list is faster and calmer. Each item has a photo, a location, a responsible trade and a due date, and it stays open until your representative signs it off, not until we declare it done. For multi-building programs, our rollout approach carries the same checklist from site to site.

Safe startup and training

Energizing a building safely requires a lockout and tagout plan, verified ratings, labeled equipment and trained people. We coordinate energization with the utility, confirm that protective device settings match the coordination study, and keep a log of each live-system step. Your staff receives a briefing before energization, not after.

Training is delivered by the people who installed or commissioned each system. Facilities staff learn the sequence of operation, alarms, shutoffs and routine maintenance. For cold buildings and pharmaceutical sites, where validation records carry regulatory weight, we format the documentation to your quality system. Owners in pharmaceutical and life sciences often ask for this level of traceability.

What you receive at turnover

The turnover package includes as-built drawings, operations and maintenance manuals, warranties with start dates, spare parts lists, test and balance reports, commissioning reports, inspection approvals and certificates. We organize them digitally and in print, indexed to the systems, so that a maintenance technician can find a pump curve in a minute.

We stay through the first season. A warranty walk at about eleven months catches seasonal issues, such as drainage after a hard storm or a refrigeration setpoint that drifts. Owners of cold storage facilities often use that walk to adjust controls before peak load, and we welcome it.

Open the building ready to run

Share your building type and target opening date, and we will draft a commissioning plan with test windows and responsibilities. For buildings in the northern part of the metro, our Brighton page describes the local code situation.

Questions Owners Ask

When does commissioning start on a project?

During design. We write the plan with the engineers so that systems are designed to be testable and test windows are on the master schedule. Starting at the end of construction almost always costs time.

What is the difference between substantial completion and turnover?

Substantial completion is the contract milestone when the building can be used for its purpose. Turnover is when documents, training, spare parts and warranties are delivered and your staff is ready to operate. We aim to deliver both together.

Can we occupy before the punch list is done?

Often, yes, provided the certificate of occupancy has been issued and safety systems are accepted. Remaining items are listed with dates and owners. We agree on an access plan for crews so that punch work does not disrupt operations.

Who witnesses the fire protection tests?

The fire authority having jurisdiction, usually the fire marshal or a designated inspector, witnesses acceptance tests for alarms, sprinklers, pumps and hydrants. We schedule them, run the tests and supply the paperwork. The result is a signed approval that supports occupancy.

How are warranties handled?

Each warranty starts at a defined date and is recorded in the closeout package with the manufacturer contact. We perform a warranty walk near the end of the first year and resolve covered items through the responsible subcontractor.
