DEEP Standardized Cold Storage Building at Thomaston Garage

The Connecticut Department of Energy and Environmental Protection through DAS Procurement is soliciting bids for the construction of a two-story cold storage building at Thomaston Garage to support general storage operations for the Western District and Environmental Conservation Law Enforcement divisions. The project is identified by solicitation number DEEP062526CM, posted on June 25, 2026, with responses due by July 31, 2026, under NAICS code 236220 for new construction. All materials must be delivered to the site in the manufacturer’s original, unopened packaging, clearly labeled with product name, type, stock number, manufacture date, composition by volume, thinning and application instructions, color, and handling precautions. Storage of unused materials requires tightly covered containers in a well-ventilated area maintained at a minimum temperature of 45 degrees Fahrenheit. The building will be constructed in accordance with detailed technical specifications, including requirements for site demolition, sheeting and bracing, base course, flexible paving using bituminous concrete conforming to Section 4.06 and M.04, sidewalks, turf establishment, sanitary sewer piping, and storm drainage systems. Concrete specifications require compliance with AASHTO T 23 for specimen handling and curing, and all work must adhere to the applicable building code for special inspections and structural testing. The contractor must provide qualification data for steel erectors and manufacturers, welding certificates, a letter of design certification from a licensed engineer, and test reports for cast-stone units dated within the last two years. A Quality Control Plan must be maintained detailing sampling methods, testing frequencies, and personnel responsibilities, with the contractor responsible for preparing and testing concrete cylinders on-site. For projects exceeding 500 tons of bituminous concrete, field samples must be collected per AASHTO R 97. Mockups of exterior walls are required to validate aesthetic qualities, color, texture, and workmanship standards prior to full execution. Substantial completion triggers the start of all warranties, which begin either on the date of substantial completion or upon owner acceptance of the work, whichever is later. The contractor must maintain sufficient skilled labor on-site and ensure compliance with all applicable safety codes and ASTM standards. Special inspections may be waived if the structural steel is fabricated by an IAS AC472-accredited manufacturer approved by the authorities having jurisdiction. The project is located in Connecticut and all work must meet or exceed the first class standard for materials and workmanship where
