Cold Storage, Blast Freezer & Food Processing Engineering
Precision Temperature Controls & Sanitizable Structural Frameworks
Cold storage and food processing facilities push engineering to extremes that ordinary commercial buildings never see. Sustained temperatures from cooler ranges down to blast-freezer lows create continuous vapor drive, condensation, and frost-heave risk that the envelope, slab, and mechanical systems must be engineered to control. Every discipline is affected: insulated panels, vapor barriers, underslab heating, refrigeration, and sanitary drainage all have to work together, or the building will sweat, ice up, or heave.
An integrated firm is essential here because a mistake in one discipline shows up as a failure in another. A vapor barrier detail is a structural, envelope, and mechanical concern at once; an underfloor heating system is both a slab and a mechanical scope; washdown and hygienic finishes drive plumbing, drainage, and structural detailing. We coordinate refrigeration, structure, plumbing, and civil design from the outset and produce permit-ready documents that also anticipate food-safety inspection and refrigeration commissioning.

Low-Temperature Thermal Envelope & Vapor Barrier Engineering
In freezer and cooler spaces the dominant physics is vapor drive from warm, humid outside air toward cold interiors. We engineer the thermal envelope with insulated metal panels sized by thermal calculation to hold interior setpoints while limiting energy use and preventing surface condensation. A continuous, warm-side vapor barrier is detailed at every penetration, joint, and transition because a single breach lets moisture migrate, freeze, and degrade insulation. We coordinate panel R-values, dew-point analysis, and door and dock-seal details, and address the structural attachment of heavy panels. Envelope decisions are made alongside the refrigeration load to keep the building tight, dry, and thermally stable across seasonal swings.
Underfloor Heated Slab Design to Prevent Frost Heave
A freezer slab held below freezing will draw heat from the soil until the subgrade freezes, expands, and heaves the floor, cracking it over time. We design underslab frost-protection systems, glycol loops or electric heating cables embedded beneath the insulation, with control zones and monitoring to keep subgrade temperatures safely above freezing. The slab itself is engineered for heavy forklift, pallet-rack, and mobile-racking loads while accommodating thermal contraction. Insulation, heating layout, vapor retarder, and reinforcement are detailed as one integrated assembly. We coordinate the heating loop with the mechanical scope and the reinforcement and jointing with the structural scope so the finished floor stays flat, crack-controlled, and heave-free.
Food-Safety Compliant Washdown & Process Piping Infrastructure
Food processing areas are washed down frequently and must drain, sanitize, and resist corrosion. We design plumbing and process piping for hot and cold sanitation water, clean-in-place systems, and process utilities using materials and joints suited to sanitary service. Trench and slot drains are sloped and located to clear water quickly, and floors are detailed for hygienic finishes and coving that meet FDA and USDA sanitary construction expectations. We size grease and solids interceptors where processing generates them, and coordinate hose stations, floor drains, and equipment connections. Structural and plumbing details are developed together so embedded drains and depressions integrate cleanly with slab reinforcement.
Integrated Discipline Scope for Cold Storage & Food Processing Projects
One coordinated engineering team across structural, MEP, civil, and geotechnical — one point of accountability from concept through permit.
Structural Engineering
We design structure that supports heavy refrigerated loads and the demanding envelope. Scope includes framing for insulated panel walls and roofs, rooftop or penthouse refrigeration equipment support, freezer slabs with frost protection, and mezzanines. Special attention goes to thermal movement, corrosion-resistant detailing in wet areas, and seismic bracing of tall storage racks per ASCE 7.
- Framing and attachment for insulated metal panel envelopes
- Freezer slab-on-grade with underslab insulation and heating integration
- Refrigeration equipment and penthouse support structures
- Seismic bracing of high-density and mobile racking
- Corrosion-resistant detailing for washdown environments
MEP Engineering
MEP scope centers on industrial refrigeration and the systems that support it. We design or coordinate ammonia or CO2 refrigeration and DX systems, evaporators, condensers, and controls, along with dock heating, dehumidification, sanitary plumbing, and process utilities. Electrical distribution supports compressors, defrost, and heavy motor loads, and we address machinery-room ventilation and detection required by refrigeration safety codes.
- Industrial refrigeration and DX system design and coordination
- Refrigeration load calculations and evaporator/condenser sizing
- Machinery-room ventilation and gas detection per ASHRAE 15/IIAR 2
- Sanitary and process plumbing with CIP support
- Power distribution for compressors, defrost, and dock equipment
Civil Engineering
Site design supports refrigerated truck traffic and the utilities the plant demands. We design dock aprons, grading, stormwater management, process and sanitary sewer connections, and high-volume water service for washdown and refrigeration. Wastewater pretreatment coordination is addressed where processing loads the sanitary system.
- Refrigerated dock apron and truck court pavement
- High-capacity water service for washdown and process
- Sanitary sewer and pretreatment coordination
- Grading and stormwater detention design
Geotechnical Engineering
Freezer subgrades and heavy racking loads require careful geotechnical evaluation. We assess soils for slab support, settlement, and frost susceptibility, and provide foundation recommendations that account for underslab heating and heavy point loads.
- Subsurface exploration and frost-susceptibility evaluation
- Slab support and settlement analysis for freezer floors

- Groundwater and drainage assessment beneath slabs
