3-333 Geotech Study Use of Onsite Materials for Slope Fill Spec 333 12-22-92.pdf

This is a Technical Specification document for a geotech study related to the use of onsite materials for slope fill, prepared by a California state or local agency for a landfill monitoring well replacement project dated December 22, 1992. The specification outlines the technical requirements for investigating and characterizing onsite soil materials that may be suitable for use as slope fill at a landfill facility. The project involves the abandonment of one existing groundwater monitoring well and the installation of two new groundwater monitoring wells at designated locations. The geotech study is intended to support the engineering design and construction of slope fill using available onsite materials, with final well depths and screened intervals to be determined in the field by the Project Hydrogeologist based on observed subsurface conditions and in accordance with applicable state and local regulations and approved work plans.

The specification establishes the technical parameters and testing requirements for evaluating onsite soil materials, including sampling protocols, laboratory testing procedures, and engineering analysis necessary to determine material suitability and engineering properties. The contractor is required to provide all necessary work plans, permits, inspections, and compliance documentation as specified. The geotech study findings will inform the contractor's ability to utilize onsite materials for slope fill construction, potentially reducing material import costs and project expenses. All work must comply with California state and local environmental and groundwater protection regulations applicable to landfill operations and monitoring well installation.
