Turnover day is when your maintenance lead opens a panel and either finds a labeled, tested system or a puzzle. We treat commissioning and closeout as the last real deliverable of the job, not a paperwork exercise that happens after the crews leave. By the time your people take the keys, every system should have been started, tested against its design intent, documented and explained to the people who will run it.
On small industrial buildings the stakes are practical. A single compressor, a make-up air unit that will not hold temperature or a fire alarm panel that is not tied to the right zones can stop a production line on the first day. We run function tests before the final inspection so that surprises show up when we can still fix them quickly and quietly.
This page describes how we organize start-up, inspections, training and records for owners who want a building that works the week they move in.
What turnover includes
We start with a commissioning plan written during construction. It lists every system to be tested, the test method, who witnesses it and what the acceptable result is. Typical systems include electrical distribution, lighting controls, fire alarm and sprinklers, mechanical equipment, compressed air, overhead doors and dock equipment, and any process utilities.
At the end of testing we deliver a turnover binder, digital and printed: as-built drawings, equipment submittals, operation and maintenance manuals, warranties, test and balance reports, inspection records, and a list of spare parts with suppliers. We also hand over keys, access cards, keying schedules and a contact sheet for every trade, so a service call is a phone call rather than a search.
Warranty tracking is part of closeout. We log each warranty start date, the responsible trade and the manufacturer contact, and we schedule a walk with your team before the warranty period ends so that small defects are claimed while they are still covered. Owners who keep that log find it saves far more than it costs.
Inspections and the certificate
A certificate of occupancy depends on a chain of approvals. The building must satisfy the 2021 New Mexico Commercial Building Code, which uses the 2021 International Building Code as amended, and the energy code, which follows the 2021 International Energy Conservation Code as amended and took effect January 30, 2024. Electrical work is inspected to the 2020 National Electrical Code as adopted by the state.
Inside the City of Santa Fe, fire review uses the 2021 International Fire Code with city amendments. We book the fire marshal's acceptance tests for the alarm and sprinkler systems early, because the fire inspection often has the longest waiting time. Our team assembles the special inspection reports, energy compliance documents and test certificates ahead of the final walk, so inspectors see a complete package.
Owner readiness matters as much as the building. Utility accounts, insurance, signage approvals, racking permits, forklift charging layouts and process equipment all need to be ready to receive the building. We keep a short list of owner tasks beside our own, because the certificate does not help if the distribution center cannot receive its first pallet or the food and beverage processing plant has no sanitation sign-off.
Testing before the punch walk, not after
We run pre-functional checks as each system is completed and full functional tests when the building is closed in and conditioned. Problems found at that stage are fixed by trades who are still on site. If we waited until after the final inspection, the same fix would require a call-back and a schedule that no one has planned for.
We also run a joint walk with your operations and maintenance staff. They point out things drawings do not show, such as where a forklift tends to clip a corner, how a door gets used in January or which valve they reach most often. We record those items and resolve them before turnover, which is much cheaper than discovering them in daily use.
Seasonal commissioning is a real issue at altitude. Heating systems cannot be fully tested in July and cooling systems cannot be fully tested in January, so we plan for a seasonal check. We return in the opposite season to verify performance, adjust controls and correct anything that only shows up under that load.
Training and safe start-up
Start-up of energized and pressurized systems follows written procedures. We confirm lockout points, label panels and valves, and verify that emergency stops, fire alarm initiation and exit lighting work as designed. Where the building will store chemicals, fuels or compressed gases, we review segregation and ventilation with your safety lead before the first delivery.
Training happens on site with the actual equipment. Manufacturers' representatives or our own team walk your staff through routine tasks and shutdown procedures, and we record the session so new hires can watch it later. Training is part of the schedule, not an afterthought crammed into the last Friday.
Where closeout meets the rest of the work
Commissioning is easiest when it is planned from the first design meeting. See how we set that up under industrial design-build and ground-up industrial construction. If your project is an addition to an operating plant, our phased construction on occupied sites practice stages commissioning area by area.
For owners in food and beverage and data center support work, commissioning requirements are stricter and documentation is heavier, and we plan the extra time from the start. Closeout for those users often includes sanitation checks or redundancy tests that must pass before the first product or load arrives.
Ask for the commissioning plan early
Tell us what your building has to do on day one, and we will draft a commissioning plan that shows each test, each witness and each date, so there are no surprises at turnover.
Common Questions
When does commissioning actually start?
In design. Systems are specified with testing in mind, and a plan is written before equipment arrives. Active testing begins as each system is complete, with full functional tests once the building is enclosed and conditioned.
How long between substantial completion and certificate of occupancy?
It depends on inspection scheduling and the readiness of life safety systems. Fire alarm and sprinkler acceptance are often the gating items. We schedule those tests early and give you a date range rather than a promise, then update it as inspections are booked.
What documents do we receive at closeout?
As-built drawings, equipment submittals, manuals, warranties, test reports, inspection records, certificates, spare parts lists and contact sheets. We deliver them digitally and in printed binders, organized by system so your maintenance lead can find them quickly.
What happens if something fails after turnover?
Warranty items are reported through a single contact on our team, who coordinates the responsible trade. We respond promptly and keep you updated until it is fixed. Callbacks are logged so patterns show up.
Do you handle owner-furnished equipment?
Yes. We include owner equipment in the commissioning plan, coordinate its start-up with the vendor and record the results. If your supplier is late, we flag the effect on turnover right away.
