RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Contract Amendment No. 3 to the Consulting Services Agreement (CSA) with Mark Thomas & Company, Inc., effective January 2, 2018, to increase the payment limit by $15,000 to a new payment limit of $425,000, for professional engineering services for the Marsh Creek Road Bridge (Br. No. 28C-0141) Replacement Project, Clayton area. Project No. 0662-6R4079/Federal Project No. BRLS-5928(107) (District III)

FISCAL IMPACT:

This project, including the CSA, is funded by 88.53% Federal Highway Bridge Program Funds and 11.47% Local Road Funds.

BACKGROUND:

The consulting services consist of preparing plans, specifications, and estimates, including geological and hydraulic studies for the replacement of the Marsh Creek Road Bridge (Br. No. 28C-0141) over Marsh Creek in eastern Contra Costa County.

Mark Thomas & Company, Inc. was selected to provide these services. Proposed Amendment No. 3 will amend the payment limit of the agreement in order for the consultant to provide additional professional engineering services that are required to complete plans, specifications, and permits.

CONSEQUENCE OF NEGATIVE ACTION:

The project would be delayed and Federal funds would be in jeopardy.
