SUBJECT:
Title
CONSIDER AGREEMENT FOR CONTRACT SERVICES BETWEEN THE CARSON RECLAMATION AUTHORITY AND LEIGHTON CONSULTING, INC. FOR GEOTECHNICAL SERVICES ON THE FORMER CAL-COMPACT LANDFILL
Body
I. SUMMARY
This contract with geotechnical consultant Leighton Consulting, Inc., will allow them to perform document review, subsurface explorations, laboratory testing, and engineering analyses to develop geotechnical design recommendations for a proposed warehouse project on Cells 3, 4, and 5. Because the project site is a former landfill, they will prepare a project-specific work plan and update their health and safety plan (WP/HASP) for the site for submittal to DTSC and receive approval prior to commencing their exploration program.
This work is necessary for the design of the subsurface and foundation systems, particularly the structural piles. The CRA has been requested to provide the geotechnical information for Cells 3, 4, and 5 by the proposed developer for the site. Because this work benefits the developer, they are obligated to cover the cost through the current Reimbursement Agreement.
While this is a contract between Leighton and the CRA there is no net cost to the CRA. The cost of this contract would be covered by the existing Reimbursement Agreement with Carson Goose Owner, LLC, the proposed developer of Cells 3, 4, and 5 since the work would be performed on those cells. This contract is for $362,612.00, but the contractor has requested because they may encounter impenetrable materials or materials that will bind around the auger that may require abandonment and relocation of borings, an optional contingency of approximately 15 percent of the total fee estimate to attempt to address these extra costs that may be incurred.
