Washdown drains and sloped floors decide whether a food plant stays clean or fights water every shift. A processing room is hosed, foamed and sanitized daily, so the slab has to shed water to drains without ponding, the walls have to take the spray and the joints have to be sealed in ways that resist harborage. We build food and beverage processing plants from the sanitation plan outward: how the room is cleaned comes first, and the finishes, the slopes and the drains follow from it.
Colorado's food and beverage footprint ranges from brewing to dairy to pet food. A major brewery in Golden broke ground in October 2020 on a multi-hundred-million-dollar overhaul that added fermenting, aging and filtration capacity on a schedule running into 2024, and the brewery has more than 800 employees. A cheese plant in Greeley was built as an over $250 million, 883,000 square foot facility designed to use more than 7 million pounds of milk per day at full build-out. In Elyria-Swansea in Denver, a pet food plant sits beside a major railroad crossing running southwest to northeast.
Those three cases involve different processes but share the same construction demands: heavy utilities, wet conditions, tight inspection windows and little tolerance for downtime. Our food and beverage work follows one rule, which is that production areas are built to the hygiene standard the owner sets and then verified, room by room, before product enters.
Rooms, floors and finishes in a hygienic plant
A processing plant has distinct zones: raw receiving, processing, cooking or fermenting, packaging, finished goods storage and shipping. Each zone has its own floor finish, wall panel type, drain layout, air handling and pressure relationship. We lay these out with the quality team so that traffic patterns separate raw from finished product and personnel and equipment flow in a logical direction. Cold zones are designed with the principles in cold storage facility construction.
The slab is the heart of the room. We build sloped slabs to drain channels with a consistent fall, dowelled and sealed joints, curbs at wall bases and a seamless resinous topping where the owner requires one. Our industrial concrete floors practice includes moisture testing before a topping goes down, since a floor coating over a damp slab will fail within months. Drains are set before the pour, with traps, cleanouts and process wastewater routing coordinated with the plumbing and pretreatment design.
Soils, wastewater and approvals
Site history matters for food plants. In Globeville and Elyria-Swansea, neighborhood activism won a 1994 settlement with ASARCO that funded soil cleanup, a sign of legacy smelter contamination to check in due diligence near these industrial areas. We recommend an environmental review for any older industrial parcel before purchase, and we coordinate soil handling and disposal in the earthwork plan if contaminated material is found. A food plant is not a good place to discover a soil problem after the slab is poured.
Wastewater is the other permitting driver. Food and beverage processes produce high-strength wastewater, and the utility will want to see the loads, the pretreatment and the discharge limits before it agrees to serve. We start that conversation early and include equalization tanks, screening, and any dissolved air flotation or other pretreatment in the site plan. Building permits, fire review, and any food safety plan review proceed on separate tracks, and we line them up in the schedule.
Construction practices that protect the food supply
When we work in or next to an operating food plant, contamination control is a construction requirement. We use dust barriers, negative air in work zones, covered materials, clean-in-clean-out procedures for tools and equipment, and a pest-control plan agreed with the quality manager. Workers follow the plant's good manufacturing practices for hair, jewelry, footwear and personal items.
Chemical and hot-work permits are coordinated with the plant's safety lead and, where needed, with its insurer. Ammonia refrigeration lines, boiler rooms and CO2 systems each have their own tie-in procedures, and we plan those shutdowns with the plant's maintenance team. Documentation is part of the work: we keep daily logs, material certifications and test records that the quality team can show to an auditor.
Process types we plan around
Beverage plants need glycol, clean-in-place systems, filtration areas and packaging halls with high-speed lines. Dairy and meat plants need extensive cold areas, strict sanitary zoning and high water use. Bakery and dry-goods plants need dust control, allergen separation and fire protection tuned to combustible dust. Each of these is a different building, and we carry no single template. When a project includes assembly and packaging with limited processing, a manufacturing plant approach to equipment foundations and utility interconnects is often the right frame.
We also recognize that some processors share a site with other industries. The Great Western Industrial Park in Windsor lists a mix of tenants from energy to food, with dual rail interchanges to Union Pacific and BNSF, which means a processor locating there will have industrial neighbors and a rail operation to manage. We plan site access and fencing to match.
Validation is part of the schedule
A food plant is not finished when the building is. Equipment has to be installed, cleaned, commissioned and validated, and the quality team must review sanitation procedures before the first batch. We schedule the building to turn over room by room, so that the first rooms can begin equipment setting and sanitation trials while the last rooms are still being finished, and we hold a short, defined period for punch work between the two.
Our commissioning, turnover and closeout process documents each system with test records, calibration certificates and as-built drawings in a format the quality department can file. If the plant sits in a mixed industrial district such as north Denver's industrial neighborhoods, we also review the rail crossings, truck routes and shift traffic that affect deliveries of heavy equipment, so that large vessels reach the site without waiting on a closure.
Tell us what is made, washed down and shipped
Send the product, the sanitation method, the room list and the shutdown calendar. We will return a floor, drain and wall plan, with a schedule that respects your inspection and production dates.
Common Questions
How do you build a floor that stays dry and clean?
By designing the fall, the drains and the joints together. We slope to channels, seal the joints, curb the walls and apply a resinous topping where the process requires it. We also test the slab for moisture before the topping is installed to prevent debonding.
Can you expand a plant without stopping production?
In most cases, yes. We separate the new construction from the production area with barriers and a dedicated entrance, plan utility tie-ins in short shutdown windows and control dust and traffic. The quality manager approves the plan before work starts.
Who handles wastewater pretreatment?
A design engineer sizes it, and we build it alongside the plant. Because the utility needs to approve the discharge, we start conversations early and include the pretreatment in the site plan and schedule.
What is the biggest schedule risk for a new food plant?
Equipment lead times and the commissioning of the process systems, usually. The building can be ready well before the process lines are installed and validated, so we coordinate the equipment delivery sequence and leave openings for large vessels and conveyors.
Do old industrial sites create special risks?
They can. Legacy contamination, such as the smelter-related issues noted in parts of north Denver, should be assessed before purchase. We recommend environmental due diligence and we plan for soil management in the earthwork budget.
