398 Geotech Study Conejo Valley Res. Spec 398 May 1998.pdf

This is a Geotechnical Study specification document prepared for the Calleguas Municipal Water District in Ventura County, California, dated May 1998. The document outlines geotechnical investigation requirements for the Conejo Valley Reservoir project. The study encompasses soil boring, laboratory testing, and engineering analysis to characterize subsurface conditions at the proposed reservoir site. The scope includes drilling multiple boreholes to specified depths, collecting soil and rock samples, performing standard penetration tests, and conducting laboratory analyses including moisture content, grain size distribution, and shear strength testing. The geotechnical report must provide recommendations for foundation design, embankment construction, and site preparation. Specific deliverables include detailed boring logs, laboratory test results, cross-sections, and professional engineering conclusions regarding site suitability for reservoir construction.

The specification establishes technical requirements for subsurface investigation and laboratory testing methodologies to support engineering design for water infrastructure development. Testing protocols must comply with ASTM standards and industry best practices for geotechnical engineering. The work is fundamental to the larger Campus Staff Housing Replacement Project (Project No. 633) at the Calleguas Municipal Water District's 2100 E. Olsen Road facility in Thousand Oaks, California, as it provides critical subsurface data necessary for design development and construction planning. The geotechnical investigation serves as a prerequisite engineering study to inform structural and site development decisions for the housing replacement project.
