Commissioning and Closeout in Cheyenne

By March 2026, the Missile Handling Complex at F.E. Warren Air Force Base was reported 75 percent complete with a projected finish in July 2026, and the Wing Command Center was 59 percent complete with a projected finish in June 2027. Percent complete is a useful number, but the last quarter of any project is where owners learn whether the building actually works. Closeout is the work that proves it.

We treat commissioning and closeout as a project phase with its own schedule, owner and deliverables, not as a stack of paperwork at the end. That means a startup sequence for each system, functional tests witnessed by the owner and engineer, a punch list that is worked daily, training for the people who will run the building, and a closeout package that is complete when the keys change hands.

Our aim is simple. When you take occupancy, the building should work as designed, the staff should know how to operate it, and the documents should answer the questions that will come in the first year.

The work divides into four tracks. Systems startup brings mechanical, electrical, plumbing, fire protection and controls to life, one system at a time and in the right order. Testing and balancing measures airflow and water flow against the design. Functional performance testing runs each system through its sequences to prove the controls. Finally, the punch list captures every cosmetic and functional defect for correction.

Parallel to those, we assemble the documents: operation and maintenance manuals, warranties, spare parts and attic stock, test reports, inspection records, product data and record drawings that show what was actually built. Each item is tracked on a closeout log that the owner can see, so nothing surprises anyone at the last meeting.

Training is part of the scope, not a favor. The people who will run the building need to know how to shut down a zone, read an alarm panel, reset a pump and find a shutoff valve at two in the morning. We schedule sessions with the manufacturers' representatives, keep sign-in sheets and give the owner video or written guides. Warranty periods start on documented dates, and we record them so the owner can call the right company in the right year.

Final inspections confirm that the building meets the adopted codes. In the metro, Laramie County adopted the 2024 International Building Code with amendments effective January 1, 2025 and the 2024 International Fire Code effective April 15, 2025, so fire alarm, sprinkler and egress systems are tested against those editions where they govern. We confirm with the local department which edition applies to your parcel.

A certificate of occupancy is not automatic. It requires passed final inspections, resolved comments and often submitted documents such as special inspection reports and fire system certificates. We pre-inspect, close open items and request the final inspection only when the building is ready, because a failed final is slow to recover from.

Record drawings are part of the approval trail. Underground utilities, concealed conduit and sleeves are surveyed or photographed before they are covered, so the owner's maintenance staff can find them in ten years. In Cheyenne, where frost depth and wind loads were set by local criteria, the as-built record also shows the footing depths and anchorage that were actually installed.

The best commissioning starts in design. We review the sequence of operations early, ask how each system will be tested and make sure the schedule has time and access for it. Owners who bring a commissioning agent onto the team early get cleaner startups, because the agent has already read the controls drawings and noticed conflicts that would otherwise appear at the end.

Our approach connects with long-lead procurement, because equipment arriving late compresses commissioning. We also think about phased handovers, using the practices on our phased construction on occupied sites page, so each area gets its own tested, documented turnover.

Startup is a hazardous time. Energizing equipment, pressure testing piping, testing fire alarms and running generators involve stored energy and people who are not used to the site. We hold a safety briefing before each major test, control access to the area, use lockout and tagout procedures and have a named person responsible for each system.

Some buildings have strict air and water controls. Cheyenne Regional Medical Center's renovation plan includes more isolation and negative-pressure rooms added after COVID-19, and those rooms must be verified with airflow measurements, not just visual inspection. We coordinate with the owner's infection control and facilities staff for medical office buildings and hospitals so test results match the intended performance.

Public owners follow additional rules. On municipal and government construction projects, closeout includes certified payroll records, lien waivers, bonding release and formal acceptance by the governing body. We prepare the package to meet those requirements, and we flag the steps early so they do not hold the final payment.

Large technical facilities have their own sequences. At F.E. Warren Air Force Base, the Sentinel program involves a Missile Handling Complex and a Wing Command Center on different timelines, and we respect the lesson that each complex building closes out on its own schedule. For owners who manage portfolios, property management firms often want a standard closeout binder and a digital archive, which we deliver in a consistent format.

Tell us the systems in your building and your target occupancy date. We will build a commissioning and closeout schedule that protects it.

What is the difference between testing and commissioning?

Testing proves that a single device or system operates. Commissioning verifies that the whole group of systems works together as the owner intended, and it includes documentation and training. We do both and prepare the documents for either one.

When do you hand over the building?

At substantial completion, when the building can be used for its intended purpose, with a punch list of remaining items. Final completion follows when the list is cleared and all documents are delivered. We set both dates in the schedule.

How long does a punch list take?

It depends on the building and the quality of the work. We walk the building early and often so the list stays short, then we work it daily. A long list at the end usually means the trades were not inspected during construction.

Do we get training on our systems?

Yes. We schedule training sessions with the manufacturers' representatives, record them when the owner wants and provide manuals. The training is timed to when your staff is available, not just when the equipment is ready.

What goes in the closeout binder?

Warranties, operation and maintenance manuals, record drawings, test and balance reports, inspection certificates, product data, spare parts lists and contact information for every subcontractor. We provide it in paper or digital form, depending on your preference.
