333 Geotech Study Use of Onsite Materials for Slope Fill Spec 333 12-22-92.pdf

This is a Geotechnical Study Specification document prepared by Calleguas Municipal Water District for the Campus Staff Housing Replacement Project (Project No. 633) located at 2100 E. Olsen Road, Thousand Oaks, Ventura County, California. The specification outlines requirements for geotechnical investigation and analysis related to the use of onsite materials for slope fill construction. The document establishes technical standards and procedures for soil testing, material characterization, and engineering analysis necessary to determine the suitability of onsite soils for slope fill applications. The specification was dated December 22, 1992, and defines the scope of geotechnical services required to support the housing replacement project's construction planning and design phases.

The specification details testing protocols, soil classification requirements, compaction standards, and quality assurance procedures that contractors and geotechnical engineers must follow when evaluating onsite materials. The document serves as the technical basis for determining which excavated soils can be reused as fill material on slopes, thereby optimizing construction costs and material management. By establishing clear geotechnical requirements upfront, the specification enables the project to proceed with informed decisions regarding material sourcing, slope stability, and construction feasibility while ensuring compliance with engineering standards and safety requirements applicable to the water district's facilities in California.
