Phased Construction on Occupied Industrial Sites

Some of the metro's biggest industrial neighbors never stop. The Suncor refinery in Commerce City processes 98,000 barrels per day, and a brewery in Golden with more than 800 employees took on a multi-hundred-million-dollar overhaul to add fermenting, aging and filtration capacity. Operating plants do not shut down for a contractor, which is why additions, retrofits and line changes have to be built around live production.

We build phased projects on occupied sites where forklifts, trucks, shifts and sanitation schedules are part of the project. The work is planned around the operation: temporary access, dust and noise control, utility shutdown windows, fire watch and inspection hours are all written into the plan with your plant manager before the first barricade is set.

The guiding principle is that every phase leaves the facility in a safe, working state. Nothing is left half-finished at the end of a shift.

Separating Construction From Production

We begin with a site logistics plan that separates construction traffic from truck and forklift routes, defines laydown space and sets out hard barriers where the work meets operating areas. Contractor workers receive an orientation specific to your plant, covering lockout and tagout, hot work permits, chemical or food safety rules and emergency routes.

Dust, vibration and noise are controlled at the boundary. In food and beverage environments, we treat dust as a contamination risk and use negative air, sealed temporary walls and cleaning protocols agreed with your quality team.

Phases Built Around Shutdown Windows

We map every utility tie-in, switchgear change, fire sprinkler modification and slab opening and sort them into low-risk work that can run during production and high-risk work that needs a planned outage. Shutdown windows are scheduled with the plant, and each one gets a written step-by-step plan, a rehearsal and a contingency for restoring service if something fails.

Tie-ins are prepared in advance, so the actual outage is a matter of hours instead of days. Prefabricated piping spools, pre-wired panels and pre-cast pits all shorten what has to happen on the day.

Sequencing Within Shifts and Seasons

Concrete cutting, crane lifts and noisy demolition are scheduled for second or third shift, weekends or planned shutdowns. Deliveries are timed to avoid the plant's own peak shipping periods. Westminster's employer base includes manufacturing and headquarters operations such as Ball Corporation, with 1,335 employees, and Commerce City processors run on their own cycles, so we build the calendar from your own production data rather than a template.

Winter adds its own restrictions. Denver averages about 49 to 54 inches of snow a year, so we keep temporary access routes plowed, protect fresh concrete and plan roofing work with enclosure in mind to avoid exposing live operations to weather.

Crews That Work in Tight Spaces

The concrete, site and demolition crews we manage are used to working beside operating equipment. Saw-cutting, trenching for new utilities, setting equipment pads and pouring slab patches are carried out with reduced footprints, vibration monitoring where equipment is sensitive and daily cleanup. Managing these tasks as one sequence allows us to adjust to a plant's day-to-day needs.

We pair that with industrial renovations and modernization and demolition and slab replacement capability for owners who need old floors or process areas replaced in stages.

What Phasing Adds to a Budget

Phased work costs more per square foot than the same work on an empty site, because of overtime, temporary protection, extra mobilizations and slower productivity. We quantify this up front and compare options such as additional shutdowns, a longer duration or a second-shift crew.

The offsetting benefit is revenue protection. A few days of lost production at a food or beverage plant can exceed the premium for the phasing plan, and we help owners put both numbers side by side.

Facilities We Phase Most Often

Typical occupied-site projects include additions to food and beverage processing buildings, new bays on distribution centers and expanded refrigeration at cold storage facilities. For each one, we talk with operations about which areas must stay live, which can be turned over for a stretch and which can be closed outright.

New process lines inside manufacturing plants raise the same questions. Related food and beverage experience lets us anticipate sanitation, inspection and traceability requirements.

Why Metro Plants Expand Where They Stand

Relocating a plant is a larger risk than building on it. Land near rail and interstate access is scarce, and Commerce City is served by I-76, I-270, E-470 and U.S. Routes 6, 36 and 85 and two Class I freight rail lines running through the city. Existing buildings there often hold permits, tracks and utility capacity that a new site would take years to replace.

So owners choose to add bays, replace refrigeration, extend lines and expand docks on the property they already have. Our modernization work and this phasing discipline let those expansions move forward without losing the continuous operation that justifies staying put. We treat the existing plant as a client in its own right, with its own schedule and its own constraints, and we ask your operations lead to sign off on every phase boundary before it is built. That sign-off is how a three-year program stays predictable for the people who have to run the plant every day.

Common Questions

Can you build an addition without stopping production?

In most cases, yes. The key is planning the interface between old and new, which is where tie-ins, shared walls and utilities live. We build the addition as an independent structure first and then open the connection during a planned window.

How do you keep dust out of a food plant?

We use sealed temporary partitions, negative air machines, dedicated entries and cleaning protocols reviewed by your quality or sanitation lead. Dust monitoring and inspection hold points are written into the plan.

What is a realistic length for a plant shutdown tie-in?

That depends on the system. A panel changeover or sprinkler tie-in can often be done in a day with prefabrication, while main electrical service changes or refrigeration cutovers may need a long weekend. We rehearse each one and price the window you can actually give us.

Who coordinates with the plant's insurer and fire marshal?

We do, together with your risk and EHS teams. Impairments to fire protection, hot work and temporary partitions all need documentation, and we maintain that record as part of the daily log.

Can this approach work for a multi-year expansion?

Yes. Long programs are broken into phases with their own occupancy and inspection milestones, so each completed area can be commissioned and put into service while the next one is being built.
