Colony Construction delivers ag-process buildings, dairy parlors, cold-storage rooms, grain and feed structures, and controlled-environment-agriculture greenhouses across the US – California Central Valley specialty-crop processors, Idaho potato and dairy operators, Montana wheat handlers, Colorado feedlot and beef producers, and Arizona and Nevada CEA greenhouse developers. Founded in 1985 and responsible for more than 700 completed projects including large process-facility envelopes, Colony brings FDA FSMA fluency, USDA-inspected construction discipline, and cold-storage envelope experience to US agricultural owners. Every frame is engineered to AISC 360-22, welded to AWS D1.1:2020, designed to FDA FSMA 21 CFR 117 for food-processing facilities and USDA FSIS for meat and poultry, integrated with NFPA 61 (agricultural and food-processing dust) where applicable, and executed under OSHA 29 CFR 1926. Clients pick Colony because an ag-process facility has to pass federal food-safety inspection and run three shifts a day, year after year – and our envelopes are built for both.
US Agricultural Construction Capabilities
Agricultural construction is a specialty category – durable, economical steel envelopes that live inside federal food-safety regulation, USDA inspection regimes, and commodity-specific building demands. California Central Valley specialty-crop processors and dairy cold-storage plants, Idaho potato and dairy operators, Montana wheat and grain handlers, Colorado beef-industry feedlot and processing, and the growing Arizona and Nevada controlled-environment-agriculture (CEA) greenhouse market all live inside different code overlays – FDA FSMA 21 CFR 117 for processing plants, USDA FSIS for meat and poultry, NFPA 61 for combustible grain dust, and IBC Group F (food processing) and U (utility/agricultural) occupancies. Colony’s large process-facility envelope experience – sawmill buildings, biomass plants, industrial process framing – transfers directly to ag-processing, dairy, cold-storage, and CEA construction.
Our US agriculture scope spans food and specialty-crop processing plants, dairy parlors and milking facilities, cold-storage and freezer envelopes for fresh-produce and meat distribution, grain, feed, and seed-handling structures, feedlot and beef-processing infrastructure, and CEA greenhouse and indoor-ag support buildings. We fabricate to ASTM A992 wide-flange and ASTM A500 HSS sections, detail envelopes to FDA FSMA preventive-control facility requirements where applicable, integrate NFPA 61 dust-classification design where grain or feed handling is present, and coordinate with NRCS conservation standards on farm-scale work where USDA cost-share is in play. Note: Colony’s US agriculture focus follows our 12 target states, with the strongest fit in California, Idaho, Montana, Colorado, Arizona, and Nevada.
Cold Storage, Processing, Dairy, and Controlled-Environment Agriculture
FDA FSMA 21 CFR 117 Food-Processing Facilities
Food-processing plants operate under FDA Food Safety Modernization Act preventive-control rules at 21 CFR 117 – sanitary design, preventive controls on allergen and pathogen exposure, cleanable surfaces, and environmental-monitoring-compatible construction. Colony designs the envelope to accept washdown, drainable floors, cleanable wall-to-floor junctions, and positive-pressure air flow that FDA inspectors expect. Sanitary design is a shell-design decision, not a finish problem.
USDA FSIS Meat and Poultry Construction
USDA Food Safety and Inspection Service requirements govern meat and poultry processing – USDA inspector office space integrated into the plant, sanitary kill-floor-to-cooler-to-packaging flow, proper drainage and sloped floors, and coordination with the USDA jurisdictional veterinarian during construction. Colony integrates FSIS requirements into the plant layout from schematic design and coordinates with the owner’s Quality Assurance team through construction.
Cold-Storage Envelopes for Fresh-Produce and Meat Distribution
Cold-storage rooms, blast freezers, and controlled-atmosphere envelopes demand insulated-metal-panel cladding coordinated with vapor barriers, under-slab heating to prevent frost heave, thermal-break detailing at structural-to-envelope interfaces, and airtight construction that passes blower-door verification. Our cold-climate envelope experience on Arctic industrial work transfers directly to 32°F, 0°F, and -10°F ag cold-storage programs.
Dairy Parlors and Active-Operation Construction
Modern rotary and parallel dairy parlors carry specialty milking-equipment layouts, wash-down sanitary design, and schedule-critical construction on active operations where cows must be milked on schedule. Colony sequences construction around the dairy’s milking rotation, integrates with the parlor-equipment vendor, and delivers the building ready for FDA Grade A Pasteurized Milk Ordinance inspection.
Grain, Feed, and Seed Handling (NFPA 61 Dust Classification)
Grain elevators, feed mills, and seed-processing plants fall under NFPA 61 combustible-dust rules – explosion venting, dust-collection integrated into structure, and ignition-source separation. Colony integrates NFPA 61 design into envelope and roof framing, coordinating with the owner’s DHA (dust-hazard analysis) and insurance-carrier recommendations from schematic design rather than as a late-phase retrofit.
Controlled-Environment Agriculture (CEA) in Arizona and Nevada
CEA greenhouse and indoor-ag facilities are a growing ag-construction segment in Arizona and Nevada where water-efficient vertical farming and climate-controlled production displace traditional open-field operation. Colony designs CEA envelopes for thermal management, integrated HVAC and LED-grow-light structural loads, and the specialty ventilation requirements indoor agriculture imposes.
Featured Projects
Interfor Adams Lake Sawmill
A large process-facility envelope with long clear-spans, integrated equipment coordination, and durable cladding – analogous to the ag-processing plants Colony delivers in California, Idaho, and Montana where a processing facility runs three shifts a day and needs to survive decades of service.
West Fraser Quesnel Sawmill
Dust- and moisture-sensitive envelope construction with integrated dust collection and mill-equipment coordination. Analogous to grain, feed, and seed-handling facilities where NFPA 61 combustible-dust rules drive envelope design and dust-collection integration.
Dockside Green Biomass Energy Facility
Bio-process facility framing with integrated mechanical equipment, tight schedule, and design-build delivery model. Analogous to dairy parlors, CEA greenhouses, and other process-intensive agricultural construction where equipment vendor integration and envelope design interlock.
Frequently Asked Questions
Which US ag segments does Colony build for – processing, dairy, cold storage, controlled-environment agriculture (CEA)?
All four, with the strongest fit across our 12 target states in California (Central Valley processing, specialty-crop cold storage, dairy), Idaho (potato processing, dairy), Montana (wheat and grain handling), Colorado (beef-industry feedlot and processing), and Arizona and Nevada (CEA greenhouse and indoor-ag). Our large process-facility envelope experience transfers across all four segments, with cold-climate and cold-storage expertise particularly applicable to California dairy and Pacific Northwest produce.
How do you handle FDA FSMA (Food Safety Modernization Act) and USDA-inspected construction requirements?
FDA FSMA 21 CFR 117 drives sanitary design of the envelope – cleanable wall-to-floor junctions, drainable floors, positive-pressure air flow, and environmental-monitoring-compatible construction. USDA FSIS meat and poultry requirements add inspector office space, kill-floor-to-cooler-to-packaging flow, and coordination with the USDA veterinarian during construction. Colony integrates both frameworks from schematic design rather than retrofitting them at permit submission.
What experience does Colony have with cold-storage insulated envelopes and vapor-sealed rooms?
Significant. Our cold-climate envelope experience on Alberta oil-sands warehouses and Arctic industrial work transfers directly to ag cold-storage programs. We deliver insulated-metal-panel (IMP) envelopes coordinated with vapor barriers, under-slab heating to prevent frost heave in freezer rooms, thermal-break structural-to-envelope detailing, and airtight construction that passes blower-door verification at commissioning.
Can you build dairy parlors and feed-lot infrastructure on active operations?
Yes. Dairy parlors and feedlot construction on active operations require scheduling construction around milking rotation, feedlot animal movement, and the owner’s production schedule. Colony sequences erection around those constraints, pre-fabricates sub-modules in our shops so field time is minimized, and coordinates with the milking or feedlot-equipment vendor end to end. The building is ready for FDA Grade A Pasteurized Milk Ordinance inspection (dairy) or routine USDA review (feedlot) at turnover.
How does Colony coordinate with NRCS conservation standards on farm-scale projects where USDA cost-share funding applies?
Natural Resources Conservation Service (NRCS) conservation practice standards apply to many farm-scale improvements where USDA EQIP or other cost-share programs fund the construction – waste-handling structures, conservation barns, tailwater-recovery infrastructure, and water-quality facilities. Our engineers design to the applicable NRCS standard (e.g., 313 Waste Storage Facility, 367 Roofs and Covers) and integrate documentation required for NRCS sign-off. The NRCS review is a shell-design input, not a post-construction compliance check.
