Receiving a certificate of occupancy does not mean a plant is ready to run. The roof drains have to be proven, the fire pump has to hit its flow, the dock levelers have to cycle, the rooftop units have to hold setpoint on a 100 degree afternoon and the electrical system has to carry its load without a trip. Commissioning is the stage where we show that all of it works, not just that it is installed.
We plan commissioning at the start of a job, not at the end. Test requirements go into the schedule, the people who will operate the building are named, and the documentation you will need to run it is defined. By the time we call substantial completion, you should already have seen the systems work at least once and know who to call if one does not.
Turnover is the handoff from the construction team to your maintenance team. Closeout is the paper that supports it: as-built drawings, operation and maintenance manuals, warranties, test reports, attic stock and training records. We treat them as part of the product, not as an administrative chore.
We sequence testing by system. Electrical first: insulation tests, ground checks, breaker settings, panel schedules and protective-device coordination where required. Then fire protection: hydrostatic tests on the underground fire main, hydrant flow, sprinkler acceptance and alarm testing with the local fire authority. Mechanical follows with air and water balance, controls point-to-point checks, and refrigeration or process cooling where applicable.
Building envelope and civil items are included. Roofs get flood or leak checks. Dock doors, levelers and seals are cycled and adjusted. Site drainage is observed under water flow, and pavement joints and striping are verified. The related fire water loop and hydrant systems carry their own acceptance tests, which we put on the same calendar.
On a border logistics building, such as a cross-dock near Santa Teresa, we add checks that matter to a shipper: dock lighting levels, door and leveler cycles under a loaded trailer, trailer restraint function, and the gate and yard lighting that make a night shift workable. We would rather find a leveler that sticks during our test than on the first day of a customer's peak.
Final approval depends on the code editions that governed the permit. New Mexico's 2020 Electrical Code, effective March 28, 2023, drives the electrical inspection, and the 2021 Commercial Energy Conservation Code, effective January 30, 2024, puts requirements on lighting, envelope and controls that inspectors will check. Plumbing and mechanical permits may fall under the 2021 or 2024 editions until January 1, 2027.
We assemble the closeout set the building official expects: inspection sign-offs, special inspection reports, test records, and the energy documentation that shows the as-built building meets the energy code. Missing pieces delay the certificate of occupancy more often than failed tests do, so we track them as items on the schedule. Early work with permitting and entitlements coordination reduces surprises at the end.
Startup is run by checklists tied to each piece of equipment. A vendor representative attends where the manufacturer requires it, our superintendent leads, and your operator observes and signs. For a cooling plant or a refrigeration system, we run the equipment under load rather than just proving it starts.
Training is scheduled as its own task, not squeezed in at the last minute. Your maintenance team gets walk-throughs of the electrical room, fire riser, mechanical equipment, controls interface and roof. We record the sessions when you want them and leave a binder or digital file that explains shutoffs, filters, lubrication and spare parts. Where the project is part of a multi-site program, we carry the checklists forward to the next site.
Testing in a desert climate has its own wrinkles. Summer highs average more than 96 degrees F in June, so a cooling system that passes in April may be marginal in July. Where the schedule allows, we plan performance checks on a hot day, or we agree on a seasonal follow-up visit so you can see the system at design load.
Dust is another factor. Blowing dust can clog filters and coat equipment during startup, and rain is rare but intense when it arrives. We protect new equipment until commissioning, change filters before turnover, and inspect roof drainage after the first real storm. Arroyo runoff after heavy thunderstorms can test site drainage in a way a hose test cannot, so we ask you to tell us what you see in the first months.
Energizing and pressurizing are the riskiest moments in a build. We use lockout procedures, written energization plans and clear communication to everyone on site. Areas around new switchgear, fire pumps and refrigeration equipment are controlled until testing is done.
We separate construction crews, vendors and your operators so no one is surprised when something starts. For a plant moving staff in during the final weeks, we also coordinate orientation: exits, assembly points, forklift routes and emergency contacts. The same discipline applies on phased occupied-site work, where startup and operations overlap.
Ask us for a commissioning outline during design and we will list the tests, the people and the documents your project needs. The earlier it exists, the less likely your opening is held by paperwork. For a trailer-heavy site, ask how we turn over a distribution center.
Planning starts at design, testing starts when systems are complete enough to test, and the final functional tests happen just before substantial completion. Rushing the middle is how problems reach the opening day.
As-built drawings, operation and maintenance manuals, warranties, test and balance reports, fire protection acceptance records, electrical test results, inspection sign-offs, training records and a list of spare parts and attic stock. We organize them by system so your staff can find them.
Yes. We schedule a review near the end of the first year with your maintenance team to catch issues that appear only after a full cycle of weather and operations. Warranty items are tracked until they are closed.
We coordinate with the refrigeration contractor and verify performance, controls and safeties. For cold-storage owners, our guide for cold storage and refrigerated owners describes the added testing.
We start walking the building well before substantial completion, both internally and with you. Items are listed by area and trade with a responsible party and a date. We close them in order of importance to operations, not in order of convenience.
