Food-Grade Warehouse and Ag Storage Construction in Portales, NM
Food-grade floors are the first thing a Portales processor asks about, and the question is a good one. About 40 dairies and a major U.S. dairy solids plant operate here, and the area continues to be a major exporter of certified organic peanut products. Warehouses that touch that supply chain live under sanitation rules that ordinary storage buildings do not: sealed slabs, coved base joints, washable walls and doors that keep pests and dust outside. We build that class of warehouse, along with ambient storage, rack-supported distribution and cold rooms, for owners in Roosevelt County.
Portales also has the rail and road network for it. BNSF provides freight service in town, and US 70, NM 88 and NM 206 serve the city. A food or ag-products warehouse here can be planned for truck loading, for rail loading, or for both, and the decision usually comes down to the volume, the packaging and the cost of building a spur against the cost of trucking to a transload.
We spend the first meeting on what the product does to a building: moisture, temperature, dust, wash-down and pest control. The rest of the design follows from those answers.
Dairy, peanut and ag-product storage
Dairy and peanut operations stress a warehouse differently, and good design starts by separating them. Dairy solids are hygroscopic and need dry, temperature-stable storage with tight control of humidity and sealed penetrations. Peanuts are bulk, dusty and sensitive to pests, so they need clean floors, smooth interior surfaces and good ventilation. Both call for floors that wash down and drain, and both need dock seals and doors that close tightly.
Owners who need cooler room storage next to ambient space can look at our food-grade warehouse and cold storage warehouse offerings, which cover insulated panels, refrigeration loads, vapor-tight floors and the code-required fire protection. The cold-chain food page explains how we coordinate those systems with the processor's quality team.
Sanitation details that pass the audit
Our scope on a processing-adjacent building is both structural and operational. We start with the shell and the slab, then build the support systems: drains, floor slopes, wall protection, lighting levels, door types, dock seals, pest-proof thresholds and wash stations. The detail work is what an auditor checks, so we document each choice and keep a binder of specifications ready for the owner's inspection program.
Foundations deserve attention too. Concrete in food buildings works best with a low-permeability mix and a sealer chosen for the cleaning chemicals in use, and the joints are laid out to avoid trapping water. When the building is expected to run forklifts and pallet jacks seven days a week, we tune joint spacing and reinforcing so the floor holds up under the traffic.
Building beside an operating plant
A processor's warehouse is a working environment, and the safety plan has to respect that. Construction next to an operating plant means separate haul routes, strict hours for noisy work, and a clear plan for keeping dust, fumes and debris out of production and storage areas. We coordinate with the plant's quality and safety teams before mobilizing, and we agree on rules for materials, tools and workers entering controlled zones.
On the site itself, the crews we coordinate follow written plans for excavation, concrete, steel erection and lifting, with daily briefings. Refrigerant and electrical work are handled under their own lockout and permit procedures. If a plant must keep running while we tie into its existing building, we plan that tie-in in short, scheduled outages, not open-ended shutdowns.
A university and a processing economy
Portales is a university town as well as a processing center, and the two markets support each other. Eastern New Mexico University, which has grown into the third-largest university in the state, announced $11.483 million in capital outlay funding for the 2025 to 2026 fiscal year in April 2025. That included $6.5 million to complete a new Student Academic Services building, $2.5 million for HVAC repairs to the Science Building and $408,000 for agriculture equipment in a new Animal Production facility.
For a builder, that kind of public spending suggests steady demand for supply and facilities storage, and the animal production link ties back to the region's dairy economy. A processor, a supplier and a campus can all use a well-built warehouse, and each of them wants different details. Our manufacturing and distribution experience helps us design a building that can host more than one user over time.
Food-grade upgrades and storage sizing
A warehouse in Portales usually costs less per square foot than the same building in a metro area, but the price is heavily influenced by its finishes. Food-grade interiors, insulated panels, refrigeration and sealed floors raise costs, and a bare ambient shell lowers them. We give owners a clear line between the base building and the food-grade upgrades so they can decide which upgrades are required by their auditors and which are optional.
The plant history is useful context. A nut company bought the Portales Peanut Plant in 2015, a 70-acre facility with a 53,000-square-foot shelling building, several large warehouses and storage for about 28 million pounds of farmer stock peanuts. That scale shows how much storage an ag-processing site can need. A smaller owner can learn from it by planning storage for harvest peaks, not average months. We discuss that planning in our warehouse expansion work.
Nearby markets and freight modes
Nearby markets matter to a Portales warehouse owner. Clovis is another eastern New Mexico market we build in, so a Roosevelt County operator can compare sites across the region. See our Clovis page for how we approach that market, or our Hobbs work if your freight heads toward the southeastern corner of the state.
The municipal airport southwest of the city is a general aviation field, so freight here moves by truck and rail. We shape every Portales building around that fact.

Common Questions
Do food and dairy buildings need special floors?
Yes. Sealed or coated slabs, coved joints and floor drains that slope correctly help meet sanitation expectations. We choose sealers based on the cleaning chemicals you use and the temperature of the room, and we lay out joints to avoid pooling.
Can a Portales warehouse be served by rail?
BNSF provides freight service in the city, so a rail connection is worth investigating. Whether a specific parcel can have a spur depends on its distance from the track, the railroad's requirements and the volume you plan to move. We price the building with and without a spur.
How big should storage be for harvest-season peaks?
Size the building for the busiest month, not the average. Peak storage drives pallet positions, dock doors and the number of trucks in the yard. We model your peak and your off-season loads, then show you the cost of building for each.
What kind of dock doors work best in food buildings?
Insulated sectional doors with tight seals, dock shelters and pest-proof thresholds usually perform best. Where product is chilled, we add vestibules or air curtains. We choose them with your quality team so they match your audit requirements.
