Washdown, not weather, wears out a food plant floor first. Hot water, caustic cleaners, acids from product, steam and thermal shock cycle on the same surface every night, and a floor that was a good warehouse slab becomes a liability in a year. We design food and beverage buildings backward from the sanitation program: what the crew sprays, how long the surface stays wet, where the water goes, and how it dries before the next shift.
Food and beverage owners include meat and dairy processors, breweries and beverage plants, ingredient and sugar processors, packaged food companies and the co-packers who serve them. Their risks are regulatory, microbiological and seasonal. A line down on a harvest week or a recall due to a harborage point costs more than the building did, so procurement teams evaluate a builder on sanitary detailing, schedule discipline during a running operation, and the quality of the turnover documentation.
We work as a design-build or construction-manager-at-risk partner and carry the owner's food safety team into the design from the first meeting. The sections below describe the codes, the scope and the cost drivers, and they link out to the cold storage and renovation work that most food plants eventually need as well.
Building code, wastewater and the inspectors
A food plant answers to more than the building department. Federal and state food safety programs set sanitary design expectations and, for meat and poultry plants, require inspection facilities for the resident inspectors. The municipal utility sets the rules for process wastewater, including strength limits and pretreatment, and the fire authority reviews ammonia refrigeration, combustible dust and grain or sugar handling. We map all these approvals at the start and carry them in a matrix with a reviewer and a date for each.
Local code editions apply to the building itself. The Home Builders Association of Metro Denver tracker dated January 20, 2026 lists Golden as enforcing the 2024 IBC, 2024 IRC and 2024 IFC since August 2025, and neighboring jurisdictions are on other editions. We confirm the edition with the building department before design is frozen, and we ask early about plan review timelines, because a pretreatment system or a refrigeration machinery room can add a separate review.
Sanitary design shapes the building
Hygienic design is a set of detailing rules that touch every trade. Walls and ceilings are smooth and cleanable. Floors slope to drains at a rate that keeps water from ponding, and drains are sized for cleaning flow and located outside traffic paths. Joints are sealed or avoided, penetrations are sleeved and sealed, and hollow sections that can harbor residue are closed. Equipment bases are raised and sealed so that crews can clean underneath. We build mockups of typical wall, floor and drain details for the food safety team to approve before they are repeated across the plant.
Zoning matters as well. Raw and ready-to-eat areas are separated by walls, air pressure and personnel flow. Employees move through gowning rooms, and materials move through designated doors. Product flow, waste flow and people flow must not cross, and we draw them on a single diagram that the owner signs. The same discipline helps pharmaceutical clients, whose approach is described under pharmaceutical and life sciences.
Floors, drains, envelope and utilities
Food plant floors are often built as a structural slab with a thermal and chemical topping, such as a urethane cement system, over a vapor barrier. Reinforcing and joints are laid out to avoid cracks that harbor bacteria, and drains, trenches and sumps are formed before the slab. The topping is applied by a specialist in controlled temperature and humidity, and we sequence it so that it is protected from other trades. Wall panels, insulated envelopes and washdown-rated doors follow.
Utilities are heavy: process water, hot water, steam, compressed air, refrigeration, wastewater and electrical service. Site drainage and detention are handled in the same package, using the practices in stormwater detention and drainage, with attention to trucks that carry product and waste across the yard. Beverage plants add fermentation and storage tanks with concrete pads, secondary containment and glycol or CO2 systems, and the pads are designed from the tank supplier's loads.
Meat, dairy, grain, sugar and beer along the plains
Colorado's food and beverage sector is concentrated near the farms and the feedlots. Cargill's beef plant at 1505 E. Burlington Ave. in Fort Morgan has a workforce of around 2,100 employees, and in June 2025 Cargill announced nearly $90 million in automation and technology for it, followed in December 2025 by an 81-unit employee apartment complex that completed a $40 million housing project. The scale of that investment shows how an operator thinks about capacity, labor and housing together. Owners in Fort Morgan and the surrounding plains are making the same trade-offs.
Agriculture and ranching, including the annual sugar beet crop, make up a large part of the economy of Brush, and Great Western Industrial Park in Windsor offers dual rail interchanges to Union Pacific and BNSF. In metro Denver, Elyria-Swansea contains a Nestle Purina PetCare plant, and Molson Coors broke ground in October 2020 on a multi-hundred-million-dollar overhaul of its Golden brewery, adding fermenting, aging and filtration capacity. Processors and brewers in Golden need the same blend of sanitary detailing and heavy utilities.
Renovation, phasing and cold space
Few food owners build entirely new. Most grow by adding to a plant that never stops, which makes phased construction on occupied sites a core skill. We separate construction from production with sealed barriers, protect product and packaging, control dust and noise, and schedule tie-ins for sanitation windows and low-volume periods. Every shift has a briefing, and every door has a rule.
Upgrades to older plants often involve new floors, new drains, new refrigeration and new envelope pieces, covered in our industrial renovations and modernization work. Food owners also need cold and frozen holding, and the details for that are on our page for cold storage and refrigerated facilities.
What raises the cost of a sanitary building
Finishes and utilities drive cost. A high-performance floor system, stainless drainage, washdown-rated doors and wall panels, and a large wastewater pretreatment system can each cost many times a conventional equivalent. Refrigeration, steam and process water add to the mechanical package. Labor is a factor on plains sites such as Brush and Fort Morgan, where housing and travel affect crew costs.
We help owners make the trade-offs by pricing options side by side. A cheaper floor topping that needs replacement in five years may cost more over a decade. A larger pretreatment system may save wastewater surcharges. A modest increase in clear height may allow a future line. The goal is a clear lifecycle cost picture that procurement and operations teams can both defend.
Send the process flow, the sanitation program and the harvest calendar
Share the product flow, zoning needs, wet-process details, wastewater strength and the seasonal dates you cannot miss. We will return a sanitary design basis, a phasing plan that protects production and a cost model with the floor, drain and utility options priced side by side.
Common Questions
Which floor system should a washdown area use?
It depends on temperature, chemicals and mechanical abuse. Urethane cement systems tolerate hot water and thermal shock, while epoxy systems suit lighter, drier duty. We ask for the sanitation chemicals and the temperature cycle, then recommend a system with a warranty that matches the duty.
How do you keep construction from contaminating a running plant?
With barriers, pressure control, traffic routes and cleaning protocols agreed with the food safety team. Crews change into clean gear, tools are cleaned before they enter production, and dust-producing work happens during sanitation windows or behind sealed enclosures. We document each step.
Can a plant expand without shutting down?
Usually yes. New space is built outside the production area, and tie-ins to utilities, floors and walls happen in short outages that fit the plant's schedule. We plan around harvest weeks and holiday volumes, and we state any date that would require a longer outage.
What approvals does a new processing line need besides a building permit?
Typically a fire review for refrigeration or dust hazards, municipal wastewater approval, and any food safety agency review that applies to the product. Some product categories require inspection facilities. We list the approvals in the first week and chase them in parallel.
How do we compare floor options on lifecycle cost?
Ask for installed cost, expected life under the actual cleaning program, repair cost and downtime for patching. We build a ten-year comparison, which usually shows that a better floor pays back by avoiding mid-life shutdowns.
