WORK ORDER NUMBER: 67567

DATED: 7 March 2019

1. GENERAL INFORMATION:

This project is intended to insulate crawl space skirting and concrete piers along the inside perimeter of the building in accordance with all applicable National, Air Force, State and local building codes and regulations. This work will consist of supplying/furnishing all labor, materials, tools, equipment, shop drawings, and expenses necessary to accomplish the work described below in compliance with the Commonwealth of Massachusetts Building Code and Massachusetts General Law requirements, Unified Facilities Criteria (UFC) state and federal codes, base standards and manufacturer’s instructions.

An alternative means is authorized (i.e. appropriate portable ladder/personnel lowering device).

2. SCOPE: Insulate crawl space skirting and concrete piers along the inside perimeter of the building.

Work is being performed in a confined space.

Products to be used as an approved equal for the listed products below must be approved by Base Civil Engineering.

Work will include:

o Installing 3.5” rigid board insulation, foil-faced on both sides (approximately 1000 square feet) on to the inside of the crawl space skirting, up against the plywood sheathing and up against the concrete piers along the inside perimeter of the building. It shall be installed on top of the 2x4 pressure treated sill and up to the galvanized steel decking (approximately 24” in height) and around the concrete piers along the inside perimeter of the building, on top of the concrete slab and up to the galvanized decking (approximately 24” in height). Horizontal edges of the rigid board insulation shall be square at the top and bottom and vertical edges shall be square on inside and outside corners and edges shall be shiplap on vertical edges where one sheet ends and another sheet begins. Shiplap joints shall be sealed with DAP Alex Plus (White) or approved equal and taped using 4” THERMAX Aluminum Foil Tape or an approved equal. Inside corners and outside corners shall be taped using 4” THERMAX Aluminum Foil Tape. Rigid board insulation shall be DOW THERMAX Sheathing or approved equal and shall be installed according to manufacturer’s instructions. All rigid board panels shall be precisely cut and installed to fit tightly. RODENHOUSE Fastening Systems or an approved equal shall be used which include Thermal-Grip ci Prong Washers and Grip-Deck ci Screws or approved equals. Fasteners shall be installed according to manufacturer’s instructions.

o Sealing edges of 3.5” rigid board insulation at the bottom of all sheets and at the top of all sheets. All gaps in the THERMAX Sheathing shall be sealed. Sealant shall be DAP Alex Plus (White) or an approved equal.

o Fabricating fastening system to install a section of 3.5” rigid board insulation to the inside of access doors to the crawl space (one on each end of the building) for the customer to install and remove the sections as needed.

3. GENERAL REQUIREMENTS:

Work includes, but is not limited to the following:

a. Provide resolutions of any technical problems that arise during the construction.

b. Should any change in scope be required, it must be coordinated with the Project POC and approved as a change order prior to performing the change in work.

c. Provide updates to Project POC. Any construction issues, changes to schedule, or schedule slippages with justification must be reported at the periodic updates.

d. The Contractor is solely responsible for compliance with the Occupational Safety and

Health Act of 1974 (OSHA) and the protection of their employees and all sub-contractor employees. In performing work under this contract on a Government installation, the contractor shall report any accidents involving Air Force property/equipment damage, or contractor personnel injuries occurring on the job or an accident resulting in death, injury, occupational disease, or adverse environmental impact to the contracting officer within five days.

e. Any modifications and addition on a facility that contains Lightning Protections System (LPS) This includes paint projects, roofing projects, projects requiring roof penetrations, installation of new HVAC or other metallic equipment, antenna installation, or other work.

Additions and modifications to the facility envelope require re-evaluation of the LPS for the completed facility as a whole. The LPS required by the addition or modification shall not be a simple addition to the LPS. The LPS must be considered a single entity and must comply with requirements of a single LPS upon completion. The LPS shall be inspected by a commercial, third-party inspector whose sole work is lightning protection, and shall be certified by this third-party inspector as compliant with AFI 32-1065 and NFPA 780, in that priority order. Projects calling for an LPS addition to an existing LPS project shall consider the configuration of the final LPS in the initial design. Projects of this type shall ensure the final LPS as a whole is compliant with AFI 32-1065 and NFPA 780, in that priority order. The same third-party inspector requirements shall apply.

f. Complete the “builder data inventory and assessment sheet” for newly installed assets, ensuring the bar code number is attached to the new equipment. Transfer bar codes from any removed equipment to the builder assessment ½ sheet form

g. Provide three (3) copies of O & M manuals and warranty letter
