U.S. General Services Administration

Pacific Highway CBP - Remodel LPOE Lobby

Statement of Work

50 Tyee Dr

Point Roberts, WA 98281

Building WA0119PR

1. SCOPE

1.1 SUMMARY

Design and build replacement standing seam metal roof and TPO roofing system. Locate source of existing leaks and ensure detailed drawings address the cause.

1.2 BACKGROUND

Land Port of Entry (LPOE) operates 24 hours a day and processes travelers entering the U.S. from Canada. Water has been leaking into the occupied space and the roof is close to the end of its service life. The roofs to the south and west are sloped towards the building. Gutters were constructed to collect the water, but we suspect that the standard flashing details were not designed to account for the reverse slope of the roof. The west roof has wide flashing caps which may direct water towards the interior of the building.

1.3 PROJECT DESCRIPTION

Redesign, remove and replace the existing standing seam metal and membrane roofing over the main building. Work may include removing the existing skylights, gutters and flashing. Pay special attention to the locations where beams, slabs, columns, gutters and roofs overlap in the middle of the building. The roof over the inspection lanes to the south does not require replacement at this time.

Drawings:

Reference attached PDF drawing “A6 Design Intent Drawing.” AutoCad files will be provided at time of solicitation. The designer is responsible for verifying the accuracy of the drawings prior to using them.

Design:

· Locate all existing roof leaks and verify with testing to confirm.

· Design new metal roofing and all flashing details for the main building. Retrofit structure to support roofing where existing skylights are.

· New TPO roofing in the two mechanical areas.

· Re-design ceiling and lighting for the interior spaces that will be affected by removing the skylights.

Preconstruction and Inspections:

· Preconstruction meeting. After design drawings have been accepted by GSA, coordinate and schedule a preconstruction meeting between GSA, Contractor and CBP to review installation procedures and coordinate the demolition and installation of the new roof.

· Initial inspection. Schedule inspection with GSA PM/COR when a representative sample of roofing, flashing etc. is scheduled to be installed to ensure that the installation is constructed per the design and manufacturers documents.

· Follow up Inspection. Periodic inspections may be conducted by GSA during construction

· Punch List Inspection. Performed punch list inspection with GSA, CBP and contractor when construction is substantially complete.

Construction:

· Install roofing, ceiling and lighting per the accepted design documents.

· Minor mold remediation on the 2x6 studs directly below the parapet wall.

· Minimize impact on 24/7 CBP operations.
