Cold Storage Facility Construction in Texas
A freezer floor can lift itself out of level if nobody plans for the cold going down into the ground. That is the first thing we explain to anyone building cold storage in Texas, and it is why we treat a cold storage building as a different animal from a dry warehouse that happens to have insulation. The envelope, the slab, the doors and the power service all have to be designed around temperature.
In the Rio Grande Valley, the Texas Department of Licensing and Regulation lists a 64,039 square foot, $10 million cold storage project in Pharr, with construction starting in October 2025 and completion planned for the end of 2026. That is a good picture of the scale and calendar a mid-size cold building runs on: a bit over a year from registration to finish, with refrigeration equipment, slab and panels all scheduled in a tight sequence. We build cold storage with a metal frame and insulated panel envelope because it gives a firm schedule and a tight building.
Here is what it takes to do it well.
The envelope: panels, vapor seal and the details that matter
The walls and roof of a cold building are usually insulated metal panels, with an insulating foam core between two metal faces. The panels are only as good as their joints. Every seam, penetration, door frame and corner is a place where warm, moist air can find cold surfaces, condense and form ice. We seal panel joints, flash the base and detail every opening with that in mind. Our insulated metal panel work is the backbone of these buildings.
The structure behind the panels is a rigid frame, with columns set to match the racking and the evaporator locations. Roof loads are heavier than a dry warehouse because evaporators, piping and sometimes condensers hang from or sit on the frame. Interior surfaces and trim, such as the washdown-friendly liners and base details, come from our liner panel and trim scope.
The floor, the energy code and the paperwork
A freezer slab sits on insulation, with heating or ventilation under it so the soil does not freeze and push the floor up. The slab design combines insulation, vapor retarder, reinforcement and the under-floor system, and it has to match the refrigeration design. We coordinate with the refrigeration engineer before the slab is detailed. Our foundation work covers the footings and columns, and the slab is poured only after the under-floor system is installed and tested.
On codes, Texas has no single statewide commercial building code. State law sets the International Building Code as the municipal floor, cities can amend it, and the State Energy Conservation Office continues to apply the International Energy Conservation Code. A refrigerated building has special treatment under energy rules, so we confirm with the city how the envelope and refrigeration systems will be reviewed. Accessibility registration with the state applies to projects of $50,000 or more.
Power, refrigeration and who is responsible for what
Refrigeration is the largest utility load in the building, and the grid is a real constraint. The Electric Reliability Council of Texas serves about 90 percent of the state's electric load, and a cold building needs reliable service, often with backup generation for the product. We ask for the electrical load calculation at the start and send it to the utility. The refrigeration contractor is normally a specialist, and we coordinate their schedule with the slab, the panels and the roof, since evaporators and piping cannot be installed until the envelope is closed in.
We prefer a design-build arrangement for this reason. When the building and refrigeration engineers talk to each other from the first week, the penetrations, supports and slab details are agreed on paper, not argued about in the field.
Where cold storage is being built in Texas
Cold storage follows trade. In the Valley, goods valued at almost $42 billion crossed the Pharr-Reynosa International Bridge in 2021, and 720,294 commercial trucks crossed that year. McAllen's foreign-trade zone, commissioned in 1973 as the first inland zone in the country, adds a customs advantage for stored goods. Further west, about 14,000 commercial trucks a day cross between two bridges at Laredo. Perishables that cross the border often need to be staged, inspected and reloaded in a cold building within a few miles.
Inland, cold buildings serve grocery distribution, food processors and pharmaceutical distributors. Their needs are close to those of a food and beverage processing plant and of a distribution center, and we draw on both. See how we approach the border markets in Pharr and Laredo.
Doors, docks and the details owners overlook
Cold buildings need insulated dock doors, vestibules, air curtains, strip doors and sealed levelers. Each warm air leak adds refrigeration load, so we choose dock equipment with the operator. Roof drainage matters too. Texas led the nation with 878 hail events in 2024, and a membrane or panel system that gets damaged lets water into the insulation. We specify hail-appropriate roof finishes and ask about your insurer's requirements.
Product receiving also affects layout. Staging rooms, chilled corridors and docks at different temperatures should be set out in the first sketch. It is much cheaper to move a wall on paper than on a slab.
What a cold building costs more than a dry one
Expect the building to cost significantly more per square foot than a dry warehouse, before refrigeration equipment. The extra comes from insulated panels, the slab system, specialty doors, vapor control and heavier electrical. Where an owner wants to save, the right places are usually clear height, the amount of freezer versus cooler space, and the finish level of the office. The wrong places are the vapor barrier, the panel joints and the slab insulation, because failures there are expensive and visible. We price those items separately in the proposal.
Growers and packers, covered in our agriculture and agribusiness work, are often the end users of these buildings.

Common Questions
Why does a freezer need heat under the slab?
Cold passing down through the slab can freeze the moisture in the soil. Frozen soil expands and lifts the floor, cracking it and displacing racking. A heated or ventilated sub-slab, together with insulation, keeps the ground above freezing. It is a small cost compared with replacing a floor.
Can a metal building be a cold storage building?
Yes. A rigid frame with insulated metal panels is a common and cost-effective way to build cold storage. The frame holds the loads. The panels and details make the envelope airtight. The refrigeration system is designed around the building and installed after it is closed in.
How long does a mid-size cold building take?
A project like the 64,039 square foot Pharr facility registered with the state ran from an autumn 2025 start to a planned finish at the end of 2026. Foundations, envelope and refrigeration are done in sequence, and commissioning takes time. We plan around that and start long-lead equipment first.
Do I need backup power?
Most operators install it. The product in a freezer is worth far more than the generator, and the grid in Texas carries a lot of load. We size the pad, fuel and transfer gear into the electrical design from the start.
What affects the price the most?
The temperature zones, the amount of freezer space, the clear height and the dock count. Panel thickness is set by the temperature. We show each of these as a line so you can see which choice moves the total.
