Cold Storage Construction in the Denver Metro

Freezer floors heave from below, not from above, and that is the single fact that separates cold storage construction from ordinary warehouse building. A freezer held at minus 10 degrees pulls heat out of the soil under the slab year after year, and unless the section is insulated and heated, the frozen ground expands and lifts the floor and the racking on it. We build ground-up cold storage and freezer facilities in the Denver metro with that physics designed in from the foundation.

Projects range from a refrigerated expansion on a distribution center to a free-standing multi-temperature building with ambient, cooler and freezer zones, blast-freeze rooms, dock vestibules and an engine room. The envelope is usually insulated metal panel over a structural frame, with a continuous vapor barrier, and the structure must be able to carry refrigeration equipment, high racking and often an automated storage system.

Because the building is only as good as its seal, we manage vapor and air-tightness as a construction discipline, not as a late punch-list item.

Why Cold Chain Builds Along the North Metro Corridors

Cold storage wants highways, rail and an airport, and the north and northeast metro supply all three. Rockefeller Group bought 35.6 acres at East 152nd Avenue and Washington Street in Thornton in September 2023 for 25 Commerce Park, a three-building, 453,550 square foot industrial project. Crossroads 25 puts a 76-acre, 1.1 million square foot, six-building industrial park at the northeast corner of I-25 and E-470, with its first 828,000 square foot phase scheduled for delivery in the third quarter of 2027.

E-470 also has a full cloverleaf interchange with Peña Boulevard, giving the 47-mile toll road direct airport access. Sites in Commerce City and Gateway and Green Valley Ranch share that access. Perishable freight is time-sensitive, so cold-chain users weigh drive time to the interstate and the airport as heavily as they weigh building cost, and we start every site review by measuring both.

The Building, Layer by Layer

The slab section from the ground up is subgrade preparation, a drainage and ventilation layer, rigid insulation, a vapor barrier, a reinforced structural slab and, in freezers, under-slab heating by glycol, electric or air-duct systems. Above grade we frame the structure with columns and roof framing sized for racking and mechanical loads, then wrap it in insulated panels with sealed joints and thermal-break details at every penetration.

Refrigerated docks, vestibules and air-control systems are part of the same scope, and the interface with refrigerated dock retrofits matters if the owner already has an ambient building next door. Electrical service, controls, lighting rated for cold, fire protection suited to cold environments and an engine room for the refrigeration plant complete the package.

Concrete, Site Work and Structure We Manage Closely

Cold storage lives or dies on the slab, so we manage the concrete that matters closely. We schedule and inspect the trade partners who place and finish the structural slab, set the insulated section with correct joint staggering, install under-slab heating piping and pressure test it before concrete is placed, and cure the floor to the flatness that automated or narrow-aisle equipment demands. Details on our floor work appear in industrial concrete floors.

We also coordinate the drainage, truck court and utility systems around the building. Large racked freezers can put heavy point loads on soils, and where borings call for it we coordinate drilled pier foundations under columns and engine room equipment. Managing these packages as one scope keeps the sequence tight, from earthwork to enclosure, and prevents gaps between trades at the points where cold buildings are most vulnerable.

Fire Protection, Refrigerant and Building Code

Cold storage faces demanding fire protection design. Insulated panels, racked combustible commodities and freezer temperatures all affect sprinkler selection, and dry or pre-action systems may be required in sub-freezing areas. Refrigerant type and quantity drive mechanical code, ventilation, detection and emergency shutoff requirements, and large ammonia systems add process safety obligations.

Code editions differ by city. Commerce City adopts the 2021 International Building Code with 49 local amendments, while other metro cities have moved to later editions. We confirm which applies, resolve fire protection with the local fire marshal early and arrange pre-application meetings where large refrigerated buildings are new to a jurisdiction.

What Makes Cold Storage Expensive

Refrigeration equipment is the largest single line, followed by the insulated envelope and the engineered slab. Temperature range matters: a freezer costs more per square foot than a cooler, and a blast-freeze room costs more still. Racking systems, automation and the depth of the electrical service are the other big movers.

Owners can control cost with early decisions about footprint, ceiling height, number of temperature zones and phasing. A building with a shared engine room and consolidated dock zones costs less to build and run than one scattered across the site. We provide budget ranges at concept stage and update them as the refrigeration engineer and racking vendor commit to design.

Snow, Ice and Operating Reality

Metro winters add loads and moisture. Roof snow loads affect structural framing, and meltwater near docks can refreeze and damage seals. We design roof drainage, snow retention and apron slopes with those cycles in mind. For tenants and owners in the cold storage and refrigerated sector, we also plan for operating costs: tight envelopes, efficient lighting and heat recovery can pay back through the utility bill, and we help the owner weigh them against first cost.

Common Questions

Why does a freezer need a heated slab?

Without heat, the freezer pulls moisture and temperature from the soil, which can freeze and expand, lifting the floor and distorting racking. Under-slab heating keeps the subgrade above freezing. It is far cheaper to build into the slab than to repair a heaved floor later.

How long does a cold storage building take to build?

Typical timelines depend on size and refrigeration scope, with the slab, panel erection and refrigeration commissioning controlling the sequence. Equipment lead times can be long. We build a schedule from vendor delivery dates and show where decisions are needed to keep it moving.

Can we add a cold section to an existing warehouse instead?

Often. An addition or interior conversion may cost less than new construction, depending on slab, structure and roof capacity. We evaluate whether the existing building can support refrigeration loads and compare the cost of conversion with a new building.

What temperature ranges can you build?

From ambient and cooler ranges through standard freezers and blast-freeze rooms. Each zone has its own insulation, vapor control and equipment. We coordinate design with your refrigeration engineer so the building matches the process.

Who handles the refrigeration system?

The refrigeration contractor and engineer design and install the plant, and we build the engine room, structure, power and envelope around it. We coordinate schedules, pads, penetrations and testing so the refrigeration system and building come together without conflicts.
