STATEMENT OF WORK

From: Code 2370 To: Code 400 Acquisition Date: 3/9/2021 Location: DD#1 Complex, Portsmouth Naval Shipyard, Kittery, ME Subject: DRE-7 ISO Series 1 Freight Container Retractable Weather Assembly

1. Scope of Work:

1.1. Provide and install a retractable assembly on the exterior of Dry-dock #1 (DD#1) Dockside Refueling Enclosure #7 (DRE-7) to provide a weather-tight interface between an ISO series 1 freight container and the enclosure.

2. Basis of Bid:

2.1. The contractor shall provide a firm fixed price and reflect the value of the material, labor and equipment with a contract line item total.

3. General Requirements:

3.1. Contractor shall provide a retractable assembly tailored to seal around an ISO series 1 freight container of dimensions: 8’ wide x 8-6” tall x 20’ long. The container is centered and placed 6” into the opening of the enclosure using a crane or the side shift function of a fork truck. The container sits directly on a concrete pad. The assembly must include vertical and head curtains that provide a watertight seal around the freight container and enclosure opening, such that no additional external rain diversion device when sealed around the container.

3.2. Operation. Assembly must be permanently affixed to the building and extend forward a minimum of 24” when needed to seal around the container by a mechanism that is operable by hand force from the ground level. When extended, the assembly shall provide constant pressure and seal against the container on three sides. When needed, the assembly must be capable of being retracted and secured up against the building by a mechanism that is operable by hand force from the ground level. Container doors must be able to be fully opened into the enclosure. Test fit up will be required prior to completion of the contract to ensure a complete and usable product.

3.3. Water Infiltration. Entire assembly must be water-tight. Any infiltration of water will not be acceptable when the assembly is positioned and sealed around the container.

3.4. Wind Loading. Product must be designed and fabricated to withstand a wind loading pressure of at least 45 MPH pounds per square foot. Provide test data showing compliance with ASTM E330/E330M. Sound engineering principles may be used to interpolate or extrapolate test results to component sizes not physically tested. Ensure complete assembly meets or exceeds the requirements of ASCE 7.

3.5. Operation Cycle Life. Design all portions of the assembly, hardware and operating mechanisms that are subject to movement, wear, or stress fatigue to operate through a minimum of one (1) cycle per month. One complete cycle is defined as when the assembly is in the retracted position, extends fully to seal around the container, and returns to the retracted position.

3.6. Corrosion. All steel components shall be corrosion resistant (i.e., galvanized steel, stainless steel, or aluminum). All exposed carbon steel surfaces (e.g., from drilled holes) must be cleaned/prepared to bare white metal and coated with primer prior to being covered.

3.7. Combustible Materials. Assembly must be constructed from noncombustible materials. No wood is permitted.

3.8. Lift Lugs. When crane lifted, the container is lifted with Caldwell Lifting Solutions Inc. Model LL Container Lift Lugs. Container lift lugs will remain installed in the lower pockets when it is placed in the building opening. The assembly must accommodate these lift lugs.

3.9. The assembly will be attached to an existing building extension – see Figure 1 through 4 for general enclosure construction/layout. No welding is permitted. Cutting/drilling is permitted on a case basis with Code 2370.4 written approval.

3.10. All dimensions shall be field verified by the contractor prior to final installation of the assembly.

3.11. Overall external dimensions of the assembly shall be minimized to maximum extent achievable.

4. Deliverables:

4.1. The assembly design shall be submitted to Code 2370.4 for approval to ensure compliance with contract prior to product installation.

4.2. Submit the following no later than 30 calendar days after contract award steps to be taken to accomplish required testing.

a) Memorandum of test procedure.

1) Proposed dates and schedule for conducting water testing.

2) Submit detailed water test procedure prior to test.

b) Water Spray Test. A hose nozzle water spray test to be conducted to prove weather tightness. 100% of penetrations must be tested. Plan for spray test to be submitted prior to performance for conformance of locations. Code 2370.4 to be present at water spray test. Test must be scheduled with a minimum 72 hours of notice and report/results must be submitted within 48 hours of test conductance. Leakage determined in rain/weather events at test areas negate passing on tests and must be sealed.

c) Rain. For safety reasons, avoid testing during rain or if rain is anticipated during testing.

d) Locating Leaks by Diagnostic Testing. Use diagnostic test methods to discover leaks through the assembly. Perform diagnostic tests on the assembly regardless of the assembly meeting or failing to meet water infiltration requirements. Apply sealing measures after diagnostic testing is complete. To verify that the applied sealing measure are effective, re-test for leaks using the same diagnostic method that discovered the leak. Reseal and retest until the envelope meets the complete weather tightness goal and all leaks thought he envelope are sealed. Any and all leaks must be addressed. Any leaks that pass the test but allow leakage during weather events (rain, snow, etc.) are considered failed areas and must be remedied within 48 hours of the leak occurrence.

e) Repair and Protection. Make final adjustment of the assembly at no additional cost to the Government. If adjustments are required to address leaks the water spray test must be repeated to prove weather tightness.

4.3. Warranty. Provide a 1 year installation warranty and 3 year manufacturer’s warranty.

4.4. Submit two (2) copies of the Operation and Maintenance Manuals. Provide operation and maintenance manuals which are consistent with manufacturer’s standard brochures, schematics, printed instructions, operating procedures, and safety precautions. Provide test data that is legible and of good quality.

4.5. Portsmouth Naval Shipyard shall retain ownership of all deliverables produced by the contractor.

4.6. All deliverables are required within 30 days of completion of on-site work.

5. Performance Period:

5.1. On-site work must be coordinated with Contracting Officer Representative and Code 2370.4 prior to scheduling. The work shall not impact Portsmouth Naval Shipyard operations. The dates may be changed based on the needs of Portsmouth Naval Shipyard.

6. Winter Construction Conditions:

6.1. The contractor shall furnish all materials, labor, equipment, and supervision required to perform project in cold weather and winter conditions.

7. Security:

7.1. The project is located in the Controlled Industrial Area (CIA), within an active construction zone. No person not known to be an American citizen of good standing and repute shall be eligible for access to Portsmouth Naval Shipyard and adjacent areas. Proof of citizenship will be required. Every person shall be required to submit information to be able to acquire a contractor’s badge for the duration of work.

7.2. DRE-7 has special security requirements. Exterior roll-top doors must be closed and locked at all times the contractor is performing work. The contractor will not be permitted to enter any portion of DRE7 other than the building extension for the container.

8. Site Supervision:

8.1. All work shall be fully coordinated with and overseen by Shipyard personnel.

8.2. Contractor shall provide all supervision, labor, materials, tools, equipment and transportation necessary to perform tasks within this project.
