General Contractor in Centennial, Colorado
Office interiors, corporate renovations and aviation-adjacent building in Centennial, planned around the I-25 corridor and the airport's mixed jurisdiction.
Corporate tenants and aviation users in Centennial rarely want the same building, and we build for both. One needs a quiet, flexible floor plate with new mechanical zoning and a lease date it cannot miss. The other needs clear floor area, high doors, fire protection suited to aircraft storage and a site that works with airfield rules. Knowing which kind of owner we are talking to changes how we staff, who we call at the city, and how we write the schedule.
Centennial's economy is a mix of corporate offices, health services, aerospace and airport business, and the building stock reflects that. A February 2025 economic impact study credits Centennial Airport with 9,236 jobs, $2.4 billion in total business revenue for 2023 and $769.5 million in payroll. The airport also recorded 360,725 aircraft operations in 2023. Those numbers translate into steady demand for hangars, shop space and offices close to the field.
We take projects here as a general contractor with a project manager's habits: a clear scope letter, a priced list of risks and a standing weekly meeting with the owner and the design team. If your building is in Centennial, or next to it, we can tell you early which review office will own your permit.
Corporate employers and a busy airport
The city's 2023 financial report names Comcast, UnitedHealth Group, Arrow Electronics, United Launch Alliance and CommonSpirit Health among Centennial's top employers. Employers of that profile generate a particular kind of construction: floor-by-floor office renovation, data and communications rooms, lab and light assembly space, and amenity upgrades that help a landlord keep a tenant through a lease cycle.
Centennial Airport hosts more than 125 businesses, spans Arapahoe and Douglas counties, and sits in unincorporated Arapahoe County next to the city. That last detail matters to a builder. A parcel on or near the field may answer to the county and the airport authority rather than to the city, and we confirm that on day one so the owner does not file with the wrong office.
Scope we take on in Centennial
Most of our Centennial work falls into three groups. The first is interior work: tenant improvements for corporate and professional users, including phased moves where part of a floor stays occupied. The second is shell renovation for older buildings that need new envelope, roofs, mechanical plants or accessibility upgrades. The third is new aviation and light industrial space, such as aircraft hangars and shop buildings with offices attached.
We price each group as its own package so an owner can see where the money goes. A tenant improvement priced by the square foot for a floor of open workstations and one for a trading floor with raised power and cooling do not belong on the same line, and we do not average them.
Work we keep under close management
On interior jobs, we keep the work that sets quality and schedule under close management: layout, framing and drywall coordination, ceiling grid, finish carpentry and punch. When one superintendent answers for both the wall layout and the finish, fewer details get lost between trades.
For renovation shells, we keep the demolition sequence and temporary protection under our superintendent. That includes dust control, protected paths for occupied floors, and the shutdown plans for fire alarm and sprinkler zones. We bring in specialty trades for mechanical, electrical and roofing and manage them on one integrated schedule.
Questions to settle before drawings go out
Three questions come up on nearly every Centennial job. Who reviews the permit: the city or the county? What code edition applies? And what does the landlord require of a contractor, from insurance to work hours to freight elevator use? The tracker dated January 20, 2026 lists Centennial on the 2021 IBC, IRC and IFC with the 2018 IEC and no plan to adopt the 2024 I-codes, so design teams can work from that edition set.
For multi-tenant buildings, we also confirm early who controls base building systems. A change to a sprinkler head or a fire alarm device is simple on paper and slow in practice if the landlord's vendor has to be involved. We list those dependencies in the preconstruction schedule, and we bring in the owner's property management team before demolition begins.
Working safely in occupied buildings
A renovation on an occupied floor carries risks that a new building does not. Noise, dust, welding, core drilling and deliveries all affect people who are still working next door. We write a site-specific safety plan, hold a pre-task meeting before each phase of risky work, and post a contact so tenants know whom to call.
Near the airfield, we also account for height and crane limits, material staging and foreign object debris. We coordinate lift plans and lay-down areas with the airport tenant or owner, and we do not set a crane until the owner confirms any airport requirements that apply.
Owners we work for here
The owners we meet in Centennial include commercial real estate developers repositioning suburban office, corporate occupiers consolidating space, aviation businesses expanding hangar capacity and health providers adding clinic suites. Each reads a bid differently, so we tailor the format. A developer wants a line-item comparison against a pro forma, and an operator wants a move-in date.
Neighboring submarkets share many of these owner types. If you are comparing sites, we can price the same program in Greenwood Village, the Denver Tech Center or Lone Tree and show the differences in review path and cost.

Tell us the address, the intended use and the date you need the space. We will walk the building or the site, name the review office, and send back a scope and a first budget range you can use for approvals.
Questions Owners Ask
Does the city or the county issue the permit near Centennial Airport?
It depends on the parcel. The airport sits in unincorporated Arapahoe County adjacent to the city and spans Arapahoe and Douglas counties, so a site on the field may follow a different path than a site across the street in the city. We check the parcel's jurisdiction with the relevant office before any design money is spent. We also ask the airport side about any height or access requirements.
What code edition should my design team use?
The tracker dated January 20, 2026 lists Centennial on the 2021 IBC, IRC and IFC with the 2018 IEC, and it reports no plan to adopt the 2024 I-codes. State energy law has its own timetable, so the energy portion of a submittal can follow a different edition than the building code. We confirm the current list with the building office at kickoff and again before submittal.
Can you renovate a floor while the rest of the building stays open?
Yes. We build a phasing plan with protected corridors, separate construction access where possible, and scheduled shutdowns for fire and life safety systems. Noisy work goes to evenings or weekends when the lease requires it. The cost of that premium time is shown in the bid so you can choose between speed and disruption.
How early should we bring in a contractor on an office conversion?
As soon as you have a test fit. Existing mechanical capacity, ceiling heights, structural limits and egress determine whether a layout is practical, and a contractor can answer those from a walkthrough in days. Learning the same facts after drawings are done usually means redesign. We offer a walkthrough and a rough order of magnitude range before you commit to a design team.
