RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute Amendment No. 1 to the Consulting Services Agreement (CSA) with CH2M Hill, Inc., effective September 11, 2018, to increase the payment limit by $97,935 to a new payment limit of $962,712, for professional engineering services for the Marsh Creek Road Bridges (#28C-0143 and 28C-0145) Replacement project and extend the term date “acceptance of the completed bridges by the Contra Costa County Board of Supervisors” to June 30, 2022, Clayton area. (County Project No. 0662-6R4083, Federal Project No. BRLS 5928 (125)) (District III)

FISCAL IMPACT:

This project, including work performed under this amendment, is funded by 88.53% Federal Highway Bridge Program Funds and 11.47% Local Road Funds.

FISCAL IMPACT: (CONT'D)

BACKGROUND:

The Public Works Director, or designee, executed a Consulting Services Agreement, dated October 6, 2015, with CH2M Hill, Inc., for professional engineering services for the Marsh Creek Road Bridges (#28C-0143 and 28C-0145) Replacement project.

This Project consists of preparing plans, specifications, and estimates, including geotechnical and hydraulic studies, construction support, project management and coordination, and environmental and right of way support for the replacement of the Marsh Creek Road Bridges (#28C-0143 and 28C-0145) over Marsh Creek in eastern Contra Costa County.

The original scope of the contract assumed that the duration of the preliminary engineering phase would be 24 months, but rather it has exceeded 24 months and the current schedule reveals it will extend to approximately 36 months. As a result of the extended preliminary engineering phase, additional project management, coordination, and design efforts are necessary. This, in conjunction with changes to the labor rates and scope incurred by a geotechnical engineer subconsultant, contributed to exceeding the contract scope and budget for the project.

Additionally, the original CSA did not state a specific termination date for the CSA, which is no longer in conformance with the current Caltrans Local Assistance Procedures Manual contract requirements.

Amendment No. 1 will amend the payment limits in order to compensate for this additional effort and set a specific termination date.

CONSEQUENCE OF NEGATIVE ACTION:

The consultant would not be compensated for services needed to complete the project.
