(Project No.: Various) (All Districts)
FISCAL IMPACT:
Work performed under this on-call Consulting Services Agreement is funded by local, state and federal funds. (100% Various Funds)
BACKGROUND:
The Public Works Department is involved in various projects in the County that require geotechnical engineering services for road, flood control, capital facilities and airport projects. After a solicitation process, eight firms were selected to provide geotechnical engineering consulting services on an “on-call” basis. These Consultants will be used to provide geotechnical engineering services as in-house expertise is not available. Seven of these on-call contracts were approved by the Board on June 10, 2025. This on-call Consulting Services Agreement will be in effect for thirty-five months.
In accordance with Government Code section 4526, the Design/Construction Division solicited Statements of Qualifications from geotechnical engineering consulting firms. Haley & Aldrich, Inc. was determined to be qualified to provide on-call geotechnical engineering consulting services for a three-year contract to assist in complying with federal, state, and local regulations.
Government Code Section 31000 and 4525 authorizes the County to contract for services including the type of geotechnical engineering consulting services that Haley & Aldrich, Inc. provides.
CONSEQUENCE OF NEGATIVE ACTION:
Without approval from the Board of Supervisors, the Consulting Services Agreement will not be in effect. A possible delay in completing projects requiring geotechnical engineering services will occur. Executing the Consulting Services Agreement will facilitate the process of design and construction for various Public Works projects requiring geotechnical engineering expertise.
