DRAFT - STATEMENT OF WORK

Dietary Walk-in Coolers and Freezers Replacement

Introduction and Overview

This Statement of Work describes general and specifics for fully renovate the existing dietary walk-in coolers and freezers at the Houston VAMC. This includes to remove and replace the cooler and freezer and all associated accessory systems to unit. The Houston VAMC requires a contractor to perform the work necessary to accomplish the goal.

1. The contractor shall provide all labor, materials, tools, equipment, expertise, administration, supervision and transportation as necessary to perform all work in accordance with provided construction specifications, drawings, all documents attached to this contract, all terms and conditions of this contract, and this statement of work. A brief overview of the scope of work is included below:

a. Provide and install temporary coolers and freezers

b. Remove and replace (5) Coolers / (3) Freezers completely. Installation will include all new associated sub systems associated with the function of the units. Contractor is responsible to ensure all measurements, power requirements, etc. are compatible with the infrastructure.

i. 5 Coolers / 3 Freezers floor panels; shall be manufactured in accordance with NSF

#7. Overall size of the walk-in to be 53’9” wide x 54’8½” long x 9’2” high with offset. The box shall be (8) compartments per drawing.

ii. 4” foam core panels shall be Underwriters Laboratories-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 a

Class 1 building type. They shall be manufactured with foamed in place CFC free

Enovate 3000 or Solstice foam system in accordance with the 2009 Federal Energy

Standards (EISA).

iii. Factory trained installation is required. All work and materials shall fall in full accordance with local and or state ordinances, and with any other prevailing rules and regulations.

iv. Panels shall consist of interior and exterior metal skins precisely foamed with steel dies and roll-form 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 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 unless required and approved by said consultant as structural support for external accessories. To insure tight joints, panel edges must have foamed-in-place tongue and groove 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 be NSF-approved. Gaskets shall not be stapled or glued to metal skins.

v. 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 as per

Section 312 of the EISA code. For calculating the R-value of the freezer, the K-factor of the foam at 20° F. (average foam temperature) shall be used. For calculating the R-value of the cooler, the K-factor of the foam at 55° F. (average foam temperature) shall be used. Factory trained installation is required. All work and materials shall fall in full accordance with local and or state ordinances, and with any other prevailing rules and regulations.

vi. Panels shall consist of interior and exterior metal skins precisely foamed with steel dies and roll-form 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.

Gaskets shall be resistant to damage from oil, fats, water and detergents and must be NSF-approved. Gaskets shall not be stapled or glued to metal skins.

vii. 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 as per

Section 312 of the EISA code. For calculating the R-value of the freezer, the K-factor of the foam at 20° F. (average foam temperature) shall be used. For calculating the R-value of the cooler, the K-factor of the foam at 55° F. (average foam temperature) shall be used.

viii. 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.

ix. Panels shall be equipped with a Speed-Lok (cam-lock) 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 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.
