Cold Storage and Refrigerated Facility Construction in Denver

Frost heave under a freezer slab does not care how well the building above it is insulated. A room held at minus 10 degrees will freeze the soil beneath it unless the slab sits on an engineered heating or ventilation system, and that one detail separates a cold storage building from an ordinary warehouse. We build refrigerated facilities across the Denver metro with the sub-slab, the vapor barrier and the panel envelope designed as a single thermal system rather than three separate subcontracts.

The buyers we work with run the cold chain: grocery and foodservice distributors, third-party cold logistics operators, and processors who need frozen or chilled holding next to production. Their pressures are consistent. Product has to stay in range through every dock opening and every power event, the building has to clear its energy and refrigeration reviews, and the schedule has to hit a customer commitment that often comes with a penalty.

Metro sites favor the corridors where rail, interstates and the airport meet. Commerce City describes itself as having two Class I freight rail lines, sitting where three major interstates meet and adjoining Denver International Airport, which is why so many cold chain operators look first at Adams County parcels. We know that ground, and we help owners weigh a rail-served parcel against a truck-only one before they commit.

Decisions that shape a cold building before design starts

Temperature zones come first. A single frozen room, a chilled room and an ambient dock each need different envelope assemblies, door types and refrigeration capacity, and the proportion of each decides the layout. Racking style follows: selective rack, drive-in and automated storage systems stress the slab in different ways and demand different flatness. We bring the racking supplier into the conversation early so the slab design reflects loads that will actually exist.

Refrigeration system choice is next. Ammonia, CO2 and synthetic refrigerant systems carry different first costs, operating profiles and permitting paths, and the machine room is sized, ventilated and located accordingly. At roughly 5,280 feet, equipment ratings and condenser performance require checking for altitude. We lay out these decisions as options with cost and schedule impacts, so your engineering team picks the system that suits the operation.

Building the envelope, slab and dock together

Our scope typically runs from site grading to turnover of a tested building. That includes a sub-slab heating or ventilation layer, insulation board under the structural slab, a floor finish built to withstand forklift traffic at low temperature, insulated metal panel walls and roof with continuous vapor control, and dock vestibules that limit warm air entry. Our experience with industrial concrete floors matters here, because a freezer floor is poured in layers with joints and curing planned for thermal movement.

The machine room, condensers, evaporators and controls are installed by specialty partners under our coordination. For operators who need to add cold space within an existing building, our refrigerated dock retrofits convert ambient docks to temperature-controlled loading without taking the whole facility offline.

Cold-chain building formats we deliver

The standard format is the cold storage facility: a multi-temperature distribution building with deep racking, a dock face on one or both sides and a refrigeration plant. Next to it sit smaller cross-dock buildings that move product between trucks without long-term storage, and processor-attached cold rooms that hold ingredients and finished goods.

Each format brings its own truck and trailer pattern. A cross-dock has many doors and constant movement, which pushes design toward a deep apron and a durable pavement section. Our work on truck terminals and cross-docks informs those layouts, and we apply the same attention to door spacing and trailer staging in cold facilities.

Where cold storage costs diverge from dry warehouse costs

The envelope, the floor and the refrigeration plant account for most of the premium. Insulated panels cost more than tilt panels or standard metal wall, and the freezer floor adds layers that a dry building does not need. Refrigeration equipment, controls and electrical service can equal or exceed the cost of the building shell, and the electrical service is often the line that carries the longest lead time.

Energy performance changes operating cost, which matters as much as first cost. Under HB22-1362, any jurisdiction updating its building code on or after July 1, 2023 must adopt an energy code at least as strict as the 2021 IECC, so envelope and equipment efficiency are code issues as well as operating ones. We model alternatives, such as thicker panels or heat recovery, so the extra first cost can be compared against projected savings.

Refrigerant safety and construction-phase protection

Refrigerant systems bring their own compliance work: ventilation, detection, emergency shutdown and, for larger ammonia inventories, process safety and risk management programs. We coordinate with the fire official early because the refrigerant type and quantity affect machine room construction and the conditions of occupancy. On site, we manage hot work and confined space entry around insulation and refrigerant piping, where a small spark or a trapped worker is a serious risk.

Cold construction has its own safety demands. Crews working in freezers during commissioning need cold-weather clothing, rest breaks and exit procedures, and the panel installation sequence is planned to keep people out from under unsecured loads. Our safety plan for these projects is written with the owner's environmental health and safety lead, not handed over as a form.

Where we build cold storage in the metro

Most refrigerated projects land north and east of downtown. Commerce City offers rail access and interstate connections; Commerce Yards at 96th Avenue and Heinz Way is a 466,000 square foot, three-building project with rail access, financed with $77.1 million, scheduled to build from April 2026 through May 2027. Thornton's Crossroads 25, a 76-acre, 1.1 million square foot park at I-25 and E-470, shows how much speculative industrial space is entering the same corridor.

We also build for food and beverage processors who need cold holding at their plants, and for operators in the wider logistics and distribution sector adding temperature-controlled bays. Whether the parcel is in Adams County, the airport area or the south metro, we start by checking utilities, drainage and the rail connection.

Common Questions

How long does a freezer slab take to build compared with a dry slab?

Longer, because it is built in layers. Excavation and compaction are followed by the sub-slab heat or ventilation system, insulation, a vapor barrier, reinforcement, the structural slab and its curing period, and each layer is inspected before the next goes down. Cold weather in the metro adds further planning. We schedule floor work after the building is enclosed so curing is controlled and the slab can be tested before racking arrives.

Is a rail spur worth it for a cold storage building?

It depends on volume and product. Rail suits high-volume frozen and bulk products that tolerate longer transit times, and it can reduce truck dependence near the airport and interstates. The spur adds earthwork, track, and a loading arrangement that needs its own temperature control, so we compare it against a truck-only layout using your actual inbound volumes before you choose.

Can existing warehouse space be converted to refrigerated use?

Often it can, but the answer depends on the slab, the roof and the electrical service. An ambient slab cannot simply be chilled; it generally needs a new insulated floor assembly with sub-slab protection, and the roof structure must carry added insulation and equipment. We do a conversion feasibility study first, comparing it with new construction on a cost-per-pallet-position basis.

What electrical service should we plan for?

Refrigeration, dock equipment, lighting and automation can add up to a large connected load, and the utility often needs substantial lead time for a new service. We ask for equipment data early, request the load analysis from your refrigeration designer and open the utility application before design is finished. Late discovery of a service limit can delay opening by months.

How do you keep product safe during construction at an operating site?

We separate the work zone from your cold rooms with temporary barriers, protect refrigerant lines and electrical feeders, and schedule shutdowns during agreed windows. Dust and vibration controls protect nearby product, and we do not tie into live systems without a written procedure that you approve. For projects inside an occupied building, our phased approach divides the work so the cold chain is never left unprotected.

Do you build to a specific pallet count or throughput target?

We build to the layout and equipment your operation requires, and we help translate throughput into building features: clear height, dock count, aisle width and refrigeration capacity. Starting from the pallet position and handling plan avoids paying for volume you cannot use. We review those numbers during preconstruction and revisit them whenever the racking or automation design changes.
