Hospital and Healthcare Facility Construction in the Denver Metro

On August 3, 2024, patients moved from the old 38th Avenue site into the new 226 bed Intermountain Health Lutheran Hospital at 12911 W 40th Ave in Wheat Ridge. A move like that is the end of a long chain: site selection, utility capacity, code review, a structure sized for equipment and redundancy, and a commissioning period in which every life safety system is proven before the first patient arrives. That chain is what a hospital contractor manages.

Hospitals are the most regulated buildings we price. Operating rooms, imaging, central plant, emergency power, medical gas, negative pressure isolation and pharmacy compounding each carry their own standards, and they must all work together on the day of inspection. Hospital owners value a builder whose preconstruction describes the risks honestly: where the central utility plant will fit, which shutdowns the existing campus can tolerate, which equipment is long-lead.

Our heavy site and utility background matters here, since the infrastructure of a hospital campus resembles that of an industrial plant: medium-voltage service, generators and fuel storage, chilled and hot water plants, and underground that cannot fail. We approach those systems with the same rigor we bring to a process facility.

Hospital Districts in the Metro

Hospital work in this metro tends to cluster. In Englewood, Swedish Medical Center and Craig Hospital were two of the top three employers in 2023, and the hospital district is described as the backbone of the city's economy. In Lakewood, St. Anthony Hospital built a campus on 50 acres sold from the Denver Federal Center, which opened in 2011 with about 1,500 employees. In Westminster, St. Anthony's North Hospital is listed at 1,153 employees.

The common thread is campus growth. Existing hospitals add towers, parking, central plant capacity and ambulatory buildings in stages while the hospital keeps operating. For Englewood and similar districts, this means construction squeezed into tight campuses with live ambulance routes. Anticipating those constraints is the heart of our approach.

Codes, Loads and Review

Hospitals are reviewed by the local building department and by state health agencies that license the facility, so owners face two parallel approval tracks. Denver adopted new building and fire codes on June 13, 2025 on the 2024 International Building Code, while Lakewood's published handout lists the 2021 IBC and IFC with local amendments, 36 inch frost depth, a 30 psf ground snow load and wind Exposure C.

Energy compliance adds another layer. Colorado 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 equal to the 2021 IECC and the state model electric and solar ready code, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. We coordinate with the owner's engineers so that central plant design, envelope and renewable readiness are documented consistently across permit sets.

Infection Control and Life Safety

Construction on or beside a live hospital is governed by infection control risk assessments. We build to the owner's plan: sealed barriers, negative air machines, dedicated construction elevators, sticky mats, daily cleaning and air sampling where required. Dust or water intrusion into an operating area can force a closure, so supervisors check barriers each shift.

Life safety systems have their own protocol. Fire alarm and sprinkler work is typically phased, with impairment notices to the fire marshal and fire watches when systems are down. We coordinate temporary egress changes with the hospital's safety officer and keep construction traffic separate from emergency vehicle routes. Our phased construction on occupied sites method lays out each of those protections.

How We Run the Work

We run hospital projects from a master schedule that shows every shutdown as a milestone, every barrier relocation and every inspection hold point. The central plant is usually first on the critical path, because chillers, boilers, switchgear and emergency generators have lead times longer than the rest of the building. We bring in the commissioning agent early, with commissioning and turnover planning starting in design, not at substantial completion.

Underground work is where we add most value. Medium-voltage duct banks, fire water loops, domestic water, sanitary and storm lines are installed first, tested and recorded. When a hospital depends on the utilities and power sector's infrastructure for redundant feeds, we coordinate those connections early with the utility, because their schedules are not under the owner's control.

Sequencing a Campus Project

The sequence for a typical addition is site work and utilities, foundations and structure, envelope, then interiors with commissioning overlapping the last months. We design the order so noisy and dusty work happens early and the hospital's most sensitive departments are the last to be connected to new systems.

Weather planning matters. Denver averages about 49 to 54 inches of snow a year and ranks 10th among U.S. areas of at least 50,000 people for hailstorm risk, so we plan for winter concrete protection, snow removal on ambulance routes and roof selections that handle hail. We keep the owner's team involved in a weekly look-ahead that shows every planned utility interruption three to four weeks ahead.

What Drives Hospital Cost

Mechanical, electrical, plumbing and medical systems typically represent the majority of a hospital's cost, while the structure and enclosure are a smaller share. Equipment decisions made during design, particularly imaging, surgical lighting and booms, and sterile processing, have an outsized impact on the budget. We recommend a medical equipment planner on the owner's team early.

Site conditions and phasing add cost that is not obvious in a conceptual estimate. Rerouting utilities around an operating campus, building temporary parking or access roads, and maintaining existing systems during construction all add to the price. For outpatient buildings adjacent to a hospital we recommend reviewing medical office options, which are typically cheaper per square foot, and for public hospital districts see our government and municipal work.

Plan the Shutdowns First

Bring us the campus plan and we will map utility shutdowns, barriers and long-lead equipment before design is final. Early coordination protects both the schedule and the patients.

Common Questions

How do you keep a hospital operating while building next to it?

We separate the work with sealed barriers, negative air, dedicated construction routes and pre-approved shutdown windows. The hospital's infection prevention and safety teams approve the plan, and our supervisors inspect barriers each shift. Utility interruptions are planned weeks ahead and rehearsed.

What is the longest lead item on a hospital project?

Usually the central plant equipment: switchgear, generators, chillers and boilers. Some of it takes longer to arrive than the structure takes to build. We put the procurement plan in the preconstruction scope and place orders as early as the design and the owner's approvals allow.

Who reviews a hospital permit set in the metro?

The local building department reviews the building and fire codes, and state health agencies review licensing and certain health-related requirements. The jurisdiction's adopted edition matters: Denver moved to a 2024 IBC-based code in June 2025, while others remain on 2021 or earlier editions. We confirm the review path with the owner's code consultant.

Can you build the central utility plant separately from the tower?

Yes, and it is often the right call. The plant can be bid and built ahead of or alongside the clinical building so that heating and cooling capacity is ready for commissioning. The civil and utility partners we coordinate handle the yard piping and electrical duct banks that connect it.

How do you handle contaminated or fill soils on a hospital campus?

We review environmental reports during preconstruction. Campuses on former federal or industrial land may carry cleanup oversight, such as the Colorado Department of Public Health and Environment's role at the former ordnance plant site on the Denver Federal Center. We plan soil handling and disposal before excavation starts.
