What should a Denver building owner line up before construction starts?
Flux Facility is a commercial contractor for Denver buildings. We handle construction, remodels, and facility repairs for owners and tenants. We work from the stamped drawing set and the code edition in force on the day the drawings go in.
Institutional owners in Denver add rules on top of city code. The University of Colorado Denver and Anschutz campuses publish design and construction standards for their consultants and contractors. The guideline sections there are a starting point for the design team, not the project specification itself. On or near those campuses, we read the owner standards first and build to the specification the design team writes.
Denver code set
Which building code do Denver commercial projects use now?
The 2025 Denver Building and Fire Codes
Code edition
Denver adopted these codes on June 13, 2025, and adopted second-printing updates on November 24, 2025. They took effect December 31, 2025, and construction drawings for new projects submitted after that date must use them. There are no exceptions. We check your submittal date against the edition shown on the drawings.
Denver amendments to the international codes
Plan review
Denver adopted the International Code Council codes, and a project complies with those codes plus Denver's own amendments to them. We read the Denver amendments next to the matching sections and send conflicts back to the design team.
Wind load criteria on Denver drawings
Structural
The American Society of Civil Engineers publishes a tool that covers seismic load criteria for Denver. Wind load criteria are amended in the Denver Building Code, so that tool does not cover wind. We ask the structural engineer which source the wind numbers came from.
Energy sheets follow a different edition
Energy sheets
The 2025 Denver codes bring in the 2024 international codes, with one exception: the Energy Code brings in the 2021 International Energy Conservation Code. We confirm which edition the mechanical and lighting sheets were drawn to before the trades bid them.
Jobsite access control
How do Denver commercial jobsites control subcontractor access?
- Some prime contractors on large Colorado commercial projects are beginning to require documented access control as a project condition. Ask the prime whether that condition applies before you price the site setup.
- Commercial construction liability carriers are asking for documented site security controls as a condition of coverage or favorable premium. A timestamped, exportable access log is the strongest documentation available, and we keep one for the job.
- Padlocks, key cards, and paper sign-in sheets stop working once a contractor runs several Denver metro projects at once. We plan credentials a manager can revoke from one screen instead of tracking who holds keys to which trailer.
- Subcontractor credentials can be set to expire on their own. We match the expiration date to the end of that trade's scope.
- Workers carry credentials on a phone or a card. Tell us which method your building already uses so the crew is not carrying two systems.
POWER & AUTOMATION
Battery storage, EV charging, and robots that work.
Commercial buildings are adding batteries, chargers, and floor robots faster than most contractors can keep up. We design and install battery energy storage systems, handle utility interconnection, and build EV charging from a pair of stalls to a full fleet depot.
On the automation side, we deploy cleaning and security robots that pay for themselves in labor, then keep every piece of it running. Planning any of this? Get in touch and get a real number for your building.

THE CORE TRADES
The trades that keep a building running.
HVAC, plumbing, electrical, roofing. The unglamorous work is most of the job, and slow contractors are where it costs you. Our mechanical crews handle installs and replacements, from rooftop units to boilers, chillers, and process piping.
Maintenance covers the rest: service calls, electricians, roofing, fire and life safety, landscaping, and snow. Not sure where to start? An energy audit finds the waste and funds the fix.

POPULAR PROJECTS
What we get asked for most.
QUESTIONS
Straight answers.
Who are some commercial general contractors in Denver?
Flux Facility takes commercial construction and facility work across Denver. We work from the stamped drawings, the Denver amendments to the building code, and the owner's standards for the building, and we hold the trades to that scope. Ask for our scope in writing and compare it line by line against anything else you are holding.
Can Flux do tenant finish work in an occupied Denver building?
Yes. Tell us which elevator the crew can use, the hours the landlord allows loud work, and who issues badges to trades. We build the schedule and the site setup around those three answers.
When do equipment picks get locked on a Denver commercial project?
Early, if you want a rebate through Xcel Energy's Energy Efficient Buildings program. In Xcel Energy's Colorado service territory, that application goes in as early as possible in the design process, and a building must be enrolled before equipment bidding. The program also looks for savings from at least two building systems. Tell us during design and we hold the bid package until the selections are set.
Who reports an accessibility or storm drain problem found during a Denver campus project?
On University of Colorado Denver and Anschutz property, facilities management runs its own online forms: one to report an accessibility issue, one to report an illicit discharge, meaning something entering the storm drains that does not belong there, and a service request system for building work. We use the owner's forms and send the report as soon as our crew finds the problem.
