A forklift lane, a fire lane and a construction haul route cannot share the same asphalt. On an occupied industrial site, that is the first fact the phasing plan has to respect, and the plan has to respect it for every day of the job. We build expansions, tie-ins and renovations beside running plants and distribution operations, and we start each one by drawing the live operation: shipping times, receiving doors, trailer positions, fire access, pedestrian paths, and the utilities that cannot go down.
Phasing is the discipline of cutting a project into pieces that each leave the site operable. We define each phase by its boundary, its duration, the work in it, the services it interrupts, and the condition in which it leaves the site. Where a phase needs a shutdown, we request the shutdown window months ahead, write the procedure to the minute, rehearse the pre-work, and name a go or no-go decision point the plant manager owns.
Construction crews also separate by badge and by gate. Construction personnel enter through a dedicated gate with a safety orientation specific to your site rules, and our superintendent holds a daily briefing with your operations lead. The briefing covers what is moving, what is loud, what is dusty, and where the lifts will be that day.
What an occupied-site plan has to protect
The plan protects three things in this order: people, product and uptime. People means separating pedestrian paths, forklift traffic and construction traffic, with physical barriers, not paint. Product means dust control, temperature control, and in food or pharmaceutical plants, documented containment around the work zone. Uptime means the utilities, the dock doors and the production lines, each with a stated tolerance for interruption.
Expansion beside an operating plant is common in Colorado. Molson Coors began a multi-hundred-million-dollar overhaul of its Golden brewery in October 2020, adding fermenting, aging and filtration capacity on a schedule running into 2024 at a site with more than 800 employees. In Fort Morgan, a beef plant owner announced nearly $90 million in automation and technology in June 2025. Work of that kind goes into buildings that are producing, which is the condition our phasing plans are written for.
Safety on a live site
Safety planning begins with a hazard review that joins your environmental health and safety lead and our superintendent. We identify lift paths over occupied areas, hot work near stored product, confined space entries, lockout and tagout boundaries, and excavations near live utilities. Hot work permits, lockout coordination and fire watch are written into the daily plan, not left to the foreman.
We pot-hole utilities before excavating near them, verify drawings against locates, and protect existing slabs and drains with plates and covers. Fire protection impairments are scheduled, announced and limited in duration, with a fire watch stationed whenever a system is out of service. Your insurer and your local fire district are informed before the impairment begins.
Sequencing the work in layers
We work from the outside in. Site work, new foundations, and shell go up in a closed work zone while operations continue in the existing building. The tie-in comes last, once the new building is weathertight and its utilities are tested. That order limits the number of days the existing plant is touched. For renovation inside an occupied building, we work in zones with temporary partitions, negative air where required, and daily cleaning.
Weather matters because Denver averages about 49 to 54 inches of snow a year. Snow removal must keep fire lanes and shipping routes open, and temporary construction access needs a plan so that a storm does not strand trucks. We assign snow clearing responsibility and the stockpile location in the logistics plan, in writing.
Shutdown windows and tie-ins
A shutdown window is a scarce asset. Westminster's economic profile reports 3,582,581 rentable square feet of industrial and flex space at a 2.4 percent vacancy rate (CoStar, September 2023), which illustrates how tight space can be when an owner has nowhere to move production while a building is changed. A shutdown that overruns by a day cannot be absorbed elsewhere.
For that reason we pre-build everything possible: piping spools, electrical gear on temporary supports, ductwork sections, and conduit runs. We perform a dry run of the tie-in sequence on the pre-built assembly. On the day of shutdown the crew executes a rehearsed plan with a stated duration, a rollback step if a test fails, and a restart checklist signed by operations.
Operators we plan around
Different industries tolerate different interruptions. Food and beverage plants run sanitation schedules and inspection calendars that fix when work may happen. Advanced manufacturing lines have vibration, cleanliness and calibration requirements that restrict adjacent work. Distribution operations have peak seasons when no construction near a dock is acceptable.
We ask each owner for the operating calendar at the start and place the loud, dusty and disruptive activities inside the quiet periods. A food and beverage processing plant may have a one-week annual maintenance shutdown, and the project plan is built so that its tie-in work fits that week.
Typical occupied-site scopes
Typical scopes include building additions, refrigerated dock retrofits, new dock positions, dock aprons and loading zones, mezzanines, equipment pits and pads, utility upgrades and line relocations. Each is cut into phases by the same rules: separate, protect, tie in, verify.
For wider modernization, our industrial renovations and modernization team applies the same phasing to interior work, and the two teams share one superintendent so the site has a single point of authority.

List the lines, doors and utilities that must keep running. We will return a phasing plan that protects them and shows the shutdown windows we need.
Common Questions
How do you keep our production running during construction?
By separating the work zone physically, scheduling disruptive activities for quiet periods, and prebuilding assemblies so tie-ins are short. We agree on the operating constraints with you first, then write them into the phasing plan as hard rules.
How much notice do you need for a shutdown?
As much as your operation allows, and preferably months. We prepare a shutdown plan with a minute-by-minute procedure, and we review it with your maintenance and operations leads at least two weeks before the date.
Can you work around peak seasons?
Yes. We plan the schedule around your calendar, and keep noisy or traffic-heavy activities away from peak periods. If a peak period is inflexible, we propose a different phase sequence.
What about dust, noise and vibration?
We use enclosures, negative air, temporary partitions, and scheduling to control them. Where the equipment inside is sensitive to vibration, we agree on measurement points and limits before we start and monitor them during the work.
Who is on site to coordinate with our team?
A full-time superintendent, who attends your morning briefing, and a project engineer who tracks the schedule and change control. You have a named contact for each shift.
