This is a service / maintenance or supply contract in Chesterfield, Virginia. Contact the soliciting agency for additional information.

Equipment: 1) Walk in - Freezer Provide prefabricated cold storage room assembly of size and shape to fit on existing concrete pad, but no smaller than overall Dimensions 9'8" x 9'8" x 8'6" or the largest size that will fit on the existing concrete pad. Exact overall size to be field verified prior to fabrication. Foam core panels shall be 4" think and be Underwriter Laboratories (UL)- listed as having flame spread of 25 or lower and smoke generation of 450 or lower when tested in accordance with ASTME-84-76. Panels shall be approved by Factory Mutual as Class 1 building type. They shall be manufactured with foamed in place CFC free Enovate 3000 foam system in accordance with the 2009 Federal Energy Standards (EISA). Panels shall consist of interior and exterior metal skins precisely foamed with the steel dies and rollform equipment and thoroughly checked with gauges for accuracy. Metal skins shall be treated on the inside surface with a bonding agent to ensure a stable adhesion with the chemical bonding agents of the urethane. The metal skins shall be placed into heated molds and liquid urethane injected between them. Urethane shall be Enovate 3000 foamed in place (poured, not frothed) and, when completely cured, shall bind tenaciously to metal skins to form an insulated panel. Panels shall contain 100% urethane insulation and have no internal wood or structural members between skins. To ensure tight joints, panel edges must have foamed-in-place tongues and grooves with a flexible vinyl gasket foamed-in-place on the interior and exterior of all tongue edges. Gaskets shall be resistant to damage from oil, fats, water, and detergents and must e NSF-approved. Gaskets shall not be stapled or glued to metal skins. Insulation shall be rigid urethane "Foamed-in-Place." Insulation shall have a minimum R-Value of R32 for freezers. These R-values shall be determined a per Section 312 of the EISA code. For calculating the R-value of the freezer, the K-factor of the foam at 20degrees F (average foam temperature) shall be used. For calculating the R-value of the cooler, the K-factor of the foam at 55 degrees F (average foam temperature) shall be used. All panels except corner panels shall be made in 23" and 46" widths, fully interchangeable for fast, easy assembly. Panels 11-1/2", 17-1/4", or 34-1/2" wide are to be furnished only if required to fit allocated space. To assure perfect alignment and maximum strength, corner panels shall employ a right-angle configuration with exterior horizontal dimensions of 12" on each side. Panels shall be equipped with diaphragmatic joining devices. The distance between locks shall not exceed 46". Each device shall consist of a cam action, hooked locking arm placed in one panel, and a steel rod positioned in the adjoining panel, so that when the arm is rotated, the hook engages the rod and draws the panels tightly together with the cam action. Arms and rods shall be housed in individual steel pockets. Pockets on one side of the panel shall be connected to pockets on the other side in width, by use of 2" wide metal straps set into and completely surrounded by insulation. When panels are joined together, these straps shall form lock-to-lock connections for superior strength. Locking device shall be accessible from the inside to facilitate installations in confined areas and shall be provided with flush press-fit caps. Surface mounted plastic plugs will not be accepted. Obtain the necessary mechanical permit and schedule required inspections. Remove the existing walk-in, including all components and associated materials, in accordance with safety and environmental regulations. Complete the installation of the rubber membrane roof. Install the evaporator and securely position the condensing unit on top of the walk-in. Complete the refrigerant and condensate line piping. Pressurize, evacuate, and accurately weigh in the refrigerant charge. Cut and seal all penetrations for electrical and refrigeration lines in the field by the installing contractor. Perform system startup, verify operations, and adjust controls as necessary. Refrigeration system shall be warranted for 12 months with an optional 5 (1 plus 4) year compressor warranty available.
