Phased Construction on Occupied Sites in Cheyenne

A hospital cannot close for ten years to be renovated, and Cheyenne Regional Medical Center did not plan to. The Wyoming Tribune Eagle reported in May 2021 that the center planned a roughly $115 million renovation spread over about 10 years, starting with a roughly $10 million first phase to remodel the fourth floor into a mother-baby unit and a NICU. Work like that depends on patients, staff and contractors sharing the same building without harming one another.

Phased construction is the discipline of building in pieces while the owner keeps operating. The owner might be a hospital, a school, an airport, a manufacturer, a retail center or an office tenant, and each has different things it cannot stop doing. We map those things first, then divide the project into phases that protect them, with defined boundaries, defined access and defined turnover points.

Everything in the plan serves one idea: an occupant should always know what is happening, where, and when it ends. Phasing drawings, daily coordination, written notice for utility shutdowns and a named person to call are not extras. They are how an occupied building survives its own construction.

We start by interviewing the people who use the space. Facility managers, department heads, security staff and safety officers describe what must stay open, what noises are tolerable, which hours are quiet and which utilities cannot go down. From those conversations we draw the phase boundaries and list the shutdowns, relocations and temporary conditions each phase requires.

Each phase gets its own scope, schedule, access route, protection plan and turnover checklist. The checklist includes cleaning, testing, inspections and sign-off from the owner, so a finished area returns to service without lingering punch items. In medical settings, this approach supports healthcare construction, where infection control and life safety shape every barrier.

Barriers do the quiet work of phased construction. We build rigid, sealed partitions with negative air where dust or fumes could reach occupied space, install tacky mats at exits, and keep construction traffic out of occupied corridors. Noise-producing tasks such as coring, demolition and bolt drilling in concrete are scheduled for periods the owner approves, often nights and weekends.

Life safety stays intact. Exit routes, fire alarm zones, sprinkler coverage and fire lanes are maintained in every phase, and any impairment is announced, documented and limited to the shortest possible period. Where more isolation and negative-pressure rooms were added after COVID-19 in the medical center's later phases, the same discipline of airflow control applies to our barriers.

People matter as much as air. Workers on an occupied site wear badges, sign in, attend a short orientation on the owner's rules and stay inside their work zones. Hot work, such as welding or torch-applied roofing, requires a permit and a fire watch in an occupied building, and we do not compromise on either. A quiet, well-behaved crew is the best advertisement for the next phase.

Utility interruptions are the moments of greatest risk. Electrical panel changes, water shutoffs, fire alarm tie-ins and network cutovers must be planned in detail, with rollback options if something fails. We prepare a written cutover plan for each, agree it with the owner's staff, and carry it out in the window they approve.

Seasonal calendars matter too. Schools want the heavy work in summer, retailers want to avoid the holiday season, and manufacturers schedule around production runs. Laramie County Community College and similar campuses organize their year around terms, and the Cheyenne main campus alone covers 271 acres with residence halls and athletic facilities, so we align the critical phases with breaks and work on exterior and shell items while classes are in session.

Hospitals, clinics, schools, colleges, offices, retail centers, airports and plants all need phasing. For education institutions, the key concerns are student safety, noise during instruction and access for buses and families. For campuses and schools, we separate construction traffic from student routes completely.

Airports provide a good example of phasing at scale. Cheyenne Regional Airport's runway reconstruction suspended airline service from April 4 to August 31, 2023, with service resuming September 10, 2023. That kind of full closure is rare, and where an owner can avoid it by working in sections, the savings in disruption can justify extra cost.

Phasing costs more than working in an empty building. Temporary partitions, off-hours labor, extra protection, longer durations and repeated mobilizations all add up. Owners should decide how much disruption they can accept in exchange for lower cost, and they should say so before the budget is set.

They should also decide who communicates with occupants. We provide notices, signs and a weekly look-ahead, but the owner knows the audience best. Our tenant improvements work shows how a single suite can still be a delicate project when the neighbors are in business next door.

Many phased projects are really renovations, and our renovation and adaptive reuse page explains the survey, hazardous material and structural issues that older buildings bring. Phase boundaries often follow the age and condition of the building as well as the owner's operations.

At the end of each phase, commissioning and punch-list work matter more than in a vacant project, because the area goes straight back into use. Our approach to commissioning and closeout treats every phase as its own small turnover.

Describe the building, the hours you operate and the areas that cannot be disturbed. We will propose phases, barriers and a schedule you can live with.

Can my business stay open during the work?

Usually yes, if the project is phased carefully. We identify what must stay open, build barriers and separate access, and schedule disruptive work for agreed periods. Some tasks, such as major utility shutoffs, require brief closures, and we plan them in advance.

How do you keep dust out of occupied areas?

We use sealed partitions, negative air machines with filtration, tacky mats and cleaning routines, and we keep the construction route separate from occupied corridors. In sensitive areas we monitor and adjust the controls as work changes.

What does phasing add to the cost?

It adds protection, off-hours labor, longer durations and repeated mobilizations. The amount depends on how restrictive the owner's operations are. We show the phasing cost separately so you can compare options.

How are utility shutdowns handled?

Each shutdown has a written plan with a start time, duration, responsible people and a rollback option. The owner approves it in advance and we confirm with all affected occupants. We do the work in the agreed window and test before restoring service.

Who is our point of contact during construction?

A named superintendent is on site daily and reachable by phone. We hold a weekly coordination meeting with the owner's team and send a short look-ahead so there are no surprises.
