Commissioning, Turnover and Closeout for Denver Industrial Buildings

Lakewood lists the 2021 IBC, IFC and IEBC with the 2023 NEC as adopted codes, and Denver adopted a new 2024-based building and fire code on June 13, 2025. Whichever edition governs your building, each one leaves a trail of tests, inspections and signed forms that must be complete before a certificate of occupancy is issued and the plant can run product.

We treat closeout as a project phase with its own schedule, starting well before the last wall is painted. The goal is that your operations team receives a building that works, with documents that are accurate, equipment that has been proven under load and staff who have been trained on it. A punch list is expected; a surprise is not.

The people receiving the building are usually plant managers, facility engineers and maintenance leads who will live with the result for years. We plan the handoff for them, not for a lender's checklist.

What Closeout Contains

Our closeout package includes the certificate of occupancy and final inspection sign-offs, a fire alarm and sprinkler acceptance record, backflow and hydrant test reports, electrical test and arc-flash documentation, controls point-to-point and sequence verification, balancing reports for air systems, refrigeration and process test data, roof and slab warranties, equipment operation and maintenance manuals, a spare parts and attic stock list and a set of as-built drawings reflecting every field change.

Documents are organized by system and delivered electronically in a format your maintenance software can read. We include nameplate data, serial numbers, vendor contacts and warranty start dates for each major piece of equipment, so that your team can open a work order on day one without searching for a manual.

Commissioning Before Occupancy, Not After

Commissioning starts at the design stage with a written owner project requirements document. As equipment is installed, we conduct pre-functional checks, verify installation against submittals, and then run functional tests under realistic loads. For a refrigerated building, that means pull-down tests and temperature recovery after door cycles. For a process plant, it means running utilities and interlocks before product is introduced.

We bring in the engineer of record and the equipment vendors to witness the tests and sign the results. Deficiencies are logged with an owner, a due date and a retest date, and they stay on the list until they are closed. Seasonal commissioning follows in the first summer and winter, when systems are tested against real outdoor conditions rather than shoulder-season weather.

Inspections and Energy Verification

Final inspections touch building, fire, electrical, mechanical, plumbing and, in many cases, civil and landscape. Each jurisdiction has its own approach. Colorado law ties code updates to the energy performance of the 2021 IECC and to state electric and solar ready provisions, so closeout can include energy compliance forms, lighting control testing and documentation of conduit or panel provisions for future solar.

We confirm each jurisdiction's requirements for special inspection reports, fire department acceptance tests and utility final inspections, and we schedule them in the right order. A final fire alarm test that fails the day before the city inspector arrives can delay occupancy by weeks, so we test early and test twice.

Training and Operational Safety Handoff

We run hands-on training sessions for operators and maintenance staff on dock equipment, fire systems, refrigeration controls, backup power and building automation. Sessions are recorded, attendance is documented and printed quick-reference cards are posted at equipment rooms.

Lockout and tagout points, arc-flash labels, confined space entries and roof access protocols are verified before turnover. If your operation requires a specific safety review, such as a process hazard walk-through or a food safety audit, we align the closeout schedule so your reviewers can inspect a finished building.

Sequencing the Last Ninety Days

The final quarter of a project is where schedules slip. We build a back-schedule from the occupancy date, listing every test, inspection, training session and delivery in order, with owners on each. Punch walks begin on the first completed area, not the last, and a dedicated closeout manager keeps the list from growing.

When the owner needs to move racking, equipment or inventory early, we issue partial turnovers by area, with temporary certificates where the jurisdiction allows them, so you can begin operations while remaining work is finished in a controlled way.

Connected Work

Commissioning ties together every system we build, from the fire water loop and hydrant systems to the dock equipment that connects to cold chain operations. It is also standard on our cold storage construction work and on projects for pharmaceutical and life sciences owners, where documentation expectations are higher.

For owners with existing buildings, we offer commissioning as a standalone service and prepare a baseline report that supports warranty claims and future upgrades. The same approach applies to a cold storage facility that has changed operators, and to dock upgrades such as our refrigerated dock retrofits.

Closeout Looks Different From City to City

Westminster's municipal code adopts the 2021 International Building Code, Chapters 2 through 35, as its building code, while Golden has been enforcing the 2024 IBC, IRC and IFC since August 2025. The inspector who walks your Golden building will therefore be looking for different provisions than the one in an Adams County city on the 2021 edition, even when the building type is identical.

We keep a closeout checklist for each jurisdiction that records which inspections are required, who schedules them, what documents must be on site and how the final sign-off is issued. Most of it is routine, but the details, such as whether the fire department wants to witness a flow test or whether the utility needs a separate final, are the difference between a smooth handoff and a week of lost time. Our permitting coordination carries straight through into closeout for that reason.

Plan the Handoff Early

Tell us the building, the systems and your target occupancy date. We will outline a commissioning plan and the inspections that need to be booked first.

Common Questions

How long between substantial completion and occupancy?

For a clean building, two to four weeks is common, depending on how quickly the city and fire department schedule final inspections. Buildings with complex fire protection, high-piled storage or refrigeration can take longer. We book inspections as early as the jurisdiction allows.

Can we move equipment in before the certificate of occupancy?

Sometimes. Many jurisdictions allow limited access for racking or equipment installation under a temporary arrangement, but not for storing product or running operations. We confirm with the building official before promising a date.

What should be in our as-built drawings?

Every field change to utilities, slab penetrations, equipment locations, structural modifications and electrical routing should be recorded. We keep redlines throughout the project and deliver a final electronic set along with sealed survey data for underground lines.

Do you provide seasonal commissioning?

Yes. Systems like refrigeration, heating and roof drainage behave differently in July than in January, so we return for follow-up testing and adjust setpoints. Findings feed into a warranty walk before the first year ends.

Can you commission a building someone else built?

We can. We review drawings and submittals, inspect installed systems, test performance and produce a deficiency list with recommended corrective actions.
