RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a Consulting Services Agreement (CSA) with Dynamic Dzyne Associates, Inc., (dba Substrate, Inc.) (Substrate), in an amount not to exceed $600,000, for construction management services for the Marsh Creek Road Bridge Replacement Project (Project), for the period of May 1, 2018, through June 30, 2019, Clayton area. (District III) County Project No. 0662-6R4079 / Federal Project No.: BRLS 5928 (107)

FISCAL IMPACT:

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

BACKGROUND:

BACKGROUND: (CONT'D)

The Marsh Creek Road Bridge Replacement project consists of removing an existing bridge and construction of a new bridge, pavement reconstruction, temporary and permanent waterlines, drainage improvements, erosion control, signing and striping.

Substrate was selected to provide construction management services for the Project because they were determined to be the best fit of available interested construction management consultants to provide these services as determined by County staff in charge of the Project through an open consultant selection process. Public Works has successfully negotiated with Substrate to provide the construction management services.

CONSEQUENCE OF NEGATIVE ACTION:

Without Board of Supervisors’ approval, this CSA will not be in effect. A delay in the construction of the Marsh Creek Road Bridge Replacement will occur, ultimately delaying the completion of the Project. The Project delay may also result in substantial additional Project costs and jeopardize the funding.
