RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with Dynamic Dzyne Associates, Inc. d/b/a Substrate, Inc., effective February 12, 2019, to increase the payment limit by $55,000 to a new payment limit of $655,000, with no change to the original term May 1, 2018 to June 30, 2019, for construction management services for the Marsh Creek Road Bridge Replacement Project, Clayton area. (Federal Project No. BRLS-5928-(107), County Project No. 0662-6R4079) (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 Project consists of removal of existing bridge, construction of new bridge, roadway section approaching to bridge, retaining walls, reconstruct driveway, and installation of new waterline in Clayton, California. Substrate, Inc. was selected to provide construction management services for the project.

Proposed Amendment No. 1 will amend the payment limits in order to provide additional construction management services that are needed to successfully complete the project.

CONSEQUENCE OF NEGATIVE ACTION:

The project completion would be delayed and federal funds would be in jeopardy.
