Commissioning and Closeout for Commercial Buildings in Fort Collins
A building is not finished until the air leakage test passes. Fort Collins requires commercial air leakage testing, with an alternative protocol for small commercial buildings under 5,000 square feet, and it provides a commissioning fact sheet and checklist alongside its 2024 code set. Those requirements arrive at the end of a project, when everyone is tired and schedule pressure is at its highest, so we plan for them from the first day.
Closeout is also where an owner decides whether the building they receive matches the building they paid for. We approach it as a process of proof: systems tested, documents collected, staff trained and warranties in hand. A clean closeout is the best start a building can have.
What Closeout Includes
The scope covers punch lists, final inspections, testing and balancing, functional testing of mechanical, electrical and life-safety systems, air leakage testing, commissioning reports, operation and maintenance manuals, as-built drawings, warranties, attic stock and owner training. Each item has an owner on our team and a date on the schedule.
We start the closeout list at the beginning of the project, adding items as submittals are approved and as inspections are completed. By the time the last trade finishes, most of the documents are in hand, and what remains is the testing and the walk-throughs. This avoids the common scenario where a building is physically complete and administratively stalled.
Energy Code, Envelope Testing and Documentation
Colorado law has pushed local jurisdictions toward stronger energy codes. HB22-1362 requires any county or municipality that updates a building code on or after July 1, 2023 to adopt an energy code at least as stringent as the 2021 IECC, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. Fort Collins applies the 2024 International Building Code with local amendments to permits submitted on or after April 1, 2026.
For owners, the practical meaning is that envelope and system performance are verified, not assumed. Air barrier continuity, insulation placement and window installation must be built to pass a test, and the test must be scheduled while there is still time to fix what it reveals. We coordinate with the testing agency and the design team so that a failed test results in a targeted repair, not a delay.
Complex Systems, Labs and High-Performance Buildings
Some buildings place far greater demands on commissioning than others. Colorado State University's Powerhouse Energy Campus, completed in 2014, received LEED Platinum certification in 2015 and houses 26 labs and research groups, including areas for microgrid components and engine testing. Buildings like that integrate power, ventilation and instrumentation in ways that need careful verification.
Owners who intend to certify a building to a green standard should bring the commissioning agent in during design. An early review can catch issues before they are built, and the testing plan becomes a shared document that the design team, the trades and the owner all understand. We are comfortable working with independent commissioning agents and supplying the documentation they need.
Testing in Sequence, Not in a Rush
Functional testing follows a sequence. Systems are started up, controls are programmed, balancing is completed and each system is run through its modes of operation. Fire alarm and sprinkler tests are witnessed by the authority. The envelope test comes when the building is substantially sealed and before interior finishes close up the evidence.
We keep this schedule honest. The temptation near the end is to shorten testing to meet a date, which merely moves problems into the first year of operation. We would rather tell an owner that a system needs another week than hand over a building with a problem we know about. Our occupied-site phasing experience helps when parts of a building must be commissioned and handed over while the rest is still being built.
Closeout Expectations by Owner Type
Owners care about different things at turnover. A university facilities group wants complete documentation and trained staff, since it will operate the building for decades. A hospitality group wants the building ready for guests on a fixed date, with the punch list complete. A manufacturer wants equipment foundations, utilities and controls verified.
For industrial buildings in areas like Timberline and Prospect, where small-bay suites with overhead doors are common, closeout often includes multiple tenant spaces turned over in sequence. We adapt the process to the owner, keeping the documentation consistent from suite to suite and from building to building.
Where Closeout Meets Other Services
Closeout depends on work done much earlier. Long-lead procurement determines when equipment is available to test, and permitting determines the inspections that must pass. A office building project with a shell and core scope followed by tenant fit-outs involves closeout at each stage.
We also provide a post-occupancy check, returning after a few months of operation to review performance with the owner's staff. Seasonal changes expose issues that testing in one season cannot, and a follow-up visit is a good way to catch them early. It also builds the kind of working relationship that owners value when the next project comes up.

Questions Owners Ask
When should we bring in a commissioning agent?
During design, ideally. An early review identifies conflicts and sets the testing criteria before equipment is purchased. Bringing an agent in at the end of construction limits what they can do, and it often leads to a longer startup period.
What does an air leakage test involve?
A calibrated fan pressurizes or depressurizes the building while instruments measure how much air flows through the envelope. The result is compared with the project requirement. If the building fails, the team locates the leaks and seals them, then retests.
How long does closeout take?
It depends on the size and complexity of the building. A small building may close out in a few weeks, while a complex facility may take months of overlapping testing and training. We plan closeout from the beginning of the schedule so that it is not squeezed at the end.
What documents will we receive at turnover?
You will receive as-built drawings, operation and maintenance manuals, warranties, test and balance reports, commissioning reports, certificates and attic stock. We organize them in a digital format that facilities staff can search, and we walk through them with the team.
Is training for our staff part of closeout?
Yes. Equipment suppliers and our team train your operators on the systems they will run, and we record the sessions where appropriate. Training is scheduled while the building is still quiet enough for it to be useful.
What happens if a system fails its functional test?
We identify the cause with the responsible trade and the commissioning agent, correct it and retest. The retest is scheduled quickly so the delay stays small. Test failures found before occupancy are far less costly than failures found afterward.
