DIVISION 01 PROJECT SPECIFICATIONS

GENERAL REQUIREMENTS

PART 1 – SUMMARY OF WORK (SECTION 01 11 00)

1.1 WORK COVERED BY CONTRACT DOCUMENTS

A. General: All work outlined below will be performed under a single contract.

B. Project Location: This project is located at 585-573 Kober Street, Sausalito, California 94965 at Fort Baker in the Golden Gate Natural Recreation Area, California. (Coordinates: 37.83861, -122.48111)

C. Project Background: Increased sewer flow and velocity from the Baker/Barry tunnel project has resulted in the Cavallo Lodge area being vulnerable to sewer system overflows. The manhole identified in this project fills when the Capehart lift station pumps. The manhole is not draining fast enough for the incoming flow to exit, and the temporary handicaps placed on the pumps is not a permanent solution. This section of the sewage collection system captures all flow from Rodeo Beach to Fort Baker approximately 20,000 gallons daily in a normal summer condition and winter flows can reach over 80,000 gallons daily. The project location is near public water ways and a spill would affect natural resources immediately.

D. Project Scope of Work: The Fort Baker Sewer Line & Manhole Upgrade will upsize the existing approximately 120 linear feet of 6-inch sewer main with a 10-inch section of c-900 sewer pipe between manholes EFB-DO1 to EFB-DO2. The new sewer main shall be at the same elevation and grade as the existing sewer main. This project will also replace the two manholes that will be connecting this section of pipe. The replacement manholes shall be of no less capacity than the existing manholes and at the same invert elevations. The contractor is responsible for determining elevations and setting controls at the job site. The existing manhole covers shall be used to cap the new manholes. Work will consist of demolition of existing manhole bench and reshape. Bypass pumping will be required as this is the main sewer line that captures all sewage west of its location including Fort Cronkhite, Fort Barry, and Capehart housing and offices. Trenching through asphalt in the roadway east of Building 533 Fort Baker will be necessary to install the underground sewer pipe. Excavation and patching of asphalt and base will be completed after a sand base and compaction of subgrade. Trench will taper from about 4 feet deep on upslope to about 8 feet deep at second tie in manhole.

Shoring will be needed throughout the length of the trench.

E. Measurement and Payment: Payment will be by lump sum. No measurement will be made of quantities for payment. Payment shall include all labor, materials, and incidentals necessary to complete the work. Payment will be made when all work is complete and in place, work site is clean, and all required submittals have been made.
