Report Title: Amendment to Consulting Services Agreement with Mark Thomas & Company, Inc., Countywide.
☒Recommendation of the County Administrator ☐ Recommendation of Board Committee
RECOMMENDATIONS:
APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a Consulting Services Agreement (contract) amendment with Mark Thomas & Company, Inc., effective June 24, 2025, to extend the term from August 16, 2025, to December 31, 2026, for on-call structural services, with no change to the payment limit of $800,000, Countywide. (County Project No.: Various)(All Districts)
FISCAL IMPACT:
Work performed under this amendment is funded by developer fees, local, state and federal funds for local road, flood control, and airport projects. (100% Various Funds)
BACKGROUND:
The Public Works Department is involved in various projects in the County that require structural engineering services for roads, flood control, and airport projects. Mark Thomas & Company, Inc. is one of eight firms contracted to provide structural engineering services on an “on-call” basis. The consultant may augment Public Works staff on an as-needed basis. They may be used as an extension of Public Works staff during busy times when extra help is needed or when in-house expertise is not available.
On August 16, 2022, the Board of Supervisors approved an initial contract with Mark Thomas & Company, Inc. in the amount of $800,000 for structural engineering services for the Public Works Department. The term of the agreement expires on August 16, 2025.
Amendment #1 added subconsultants to the contract while Amendment #2 revised the rate sheets.
This Amendment will extend the contract term from August 16, 2025, to December 31, 2026, which is necessary for the continuation of on-call structural engineering services through the completion of San Pablo Dam Road Storm Drain and Pavement Repair (1.2 Miles West of Wildcat Canyon Road) project, which Mark Thomas & Company, Inc. is currently providing structural engineering services under a task order. Mark Thomas & Company, Inc. was selected for structural engineering services of these projects through a qualification-based selection in accordance with Caltrans Local Assistance Procedures Manual (LAPM). Structural engineering services for these projects are anticipated to be completed by December 31, 2026.
Government Code Section 31000 and 4525 authorizes the County to contract for services, including the type of structural engineering services that Mark Thomas & Company, Inc. provides.
CONSEQUENCE OF NEGATIVE ACTION:
Without approval from the Board of Supervisors, the on-going project that Mark Thomas & Company, Inc. provides structural engineering services for will experience delays and added costs as the County solicits for new professional services.
