RFP/RFQ Description: The Ross Valley Sanitary District (District) has determined that all specialty contractors intending to work on the Pilot Tube Guided Boring (PTGB) portions of the FY 2016/17 Gravity Sewer Improvement Project must be prequalified at the time of bid. It is mandatory that all subcontractors who plan to perform the PTGB work fully complete the Prequalification Questionnaire and provide all materials requested in the Notice to Contractos, and be approved by the District to be on the final prequalified bidders list.

No bid will be accepted from a general contractor that has failed to utilize one of the Contractors on the Prequalified Bidders List for the PTGB portions of the project.

Pilot Tube Guided Boring (PTGB) Method of trenchless pipe installation employing a pilot tube, temporary auger casing, and jacking system for direct installation of a product pipe.

The FY 2016/17 Gravity Sewer Improvement Project includes the upsize of approximately 2,000 linear feet of existing sewer pipe and 5,300 linear feet of new diversion pipe at two locations in San Anselmo, California. Proposed pipes range in size from 8 to 24 in nominal pipe diameter. The project also includes reconnection and re-routing of existing laterals to the new pipes.

Approximately 520 feet of the proposed 18-inch sewer line at the intersection of Butterfield Road and Meadowcroft Drive will be installed using PTGB. This work is anticipated to encounter weathered bedrock and non-displaceable soils with blow counts as high as 75. See Attachment A for boring logs in the vicinity of the proposed PTGB work.

The project will be constructed under some constraints due to the locations being within existing utility corridors, adjacent to a busy traffic corridor, and narrow residential streets.
