412 2002 Geotech Study Lake Bard Water Filtration Spec 412 1-23-02.pdf

This is a Geotechnical Study specification document prepared for the Calleguas Municipal Water District in California, detailing technical requirements for subsurface investigation and analysis related to the Lake Bard Water Filtration project. The specification outlines comprehensive geotechnical engineering services including soil borings, laboratory testing, and geological assessment necessary to support the design and construction of water filtration infrastructure. The document establishes detailed protocols for drilling operations, sample collection, laboratory procedures for soil classification and engineering properties testing, and the preparation of a final geotechnical report with recommendations for foundation design and site preparation. The specification was dated January 23, 2002, and defines the scope of work required to characterize subsurface conditions at the project site to ensure structural integrity and proper functionality of the filtration system.

The specification incorporates industry-standard testing methods and ASTM procedures for geotechnical investigations, requiring the consultant to perform in-situ testing, obtain representative soil samples at specified depths, and conduct laboratory analysis to determine bearing capacity, settlement characteristics, and soil composition. The document emphasizes quality assurance requirements, documentation standards, and the preparation of comprehensive technical reports with geological cross-sections and engineering recommendations. The geotechnical study serves as a prerequisite investigation phase supporting the larger Calleguas Water Campus Staff Housing Replacement Project located at the district's 2100 E. Olsen Road facility in Thousand Oaks, Ventura County, California, ensuring that all subsurface conditions are properly evaluated prior to construction activities.
