RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute an amendment with Dewberry Engineers Inc. (dba Dewberry | Drake Haglan), acknowledging the Assignment and Assumption Agreement between Drake, Haglan & Associates, Inc. and Dewberry Engineers Inc. (dba Dewberry | Drake Haglan) effective September 28, 2019, and increasing the payment limit by 45,627.84 to a new payment limit of 999,309.96, effective June 8, 2021, for professional engineering services for the Marsh Drive Bridge Replacement Project, Concord area. (89% Federal Highway Bridge Program Funds, 11% Local Road Funds) County Project No.: 0662-6R4119, Federal Project No.: BRLS 5928(128) (District IV and V)

FISCAL IMPACT:

Work performed under the Marsh Drive Bridge Replacement Project contract is funded by 88.53% Federal Highway Bridge Program Funds and 11.47% Local Road Funds.

BACKGROUND:

The Marsh Drive Bridge Replacement Project (Project) consists of removing the existing bridge on Marsh Drive over Walnut Creek (State Bridge No. 28C-0442), which is seismically, structurally, and hydraulically deficient, and constructing a new concrete bridge in stages to current standard, reconstructing the roadway approaches from both ends of the bridge, constructing a new separated walking path on the south side of the bridge that will connect to the existing Iron Horse Trail, and incorporating drainage improvements, utility work, erosion control work, and roadway signing and striping.

On October 10, 2017, County contracted with Drake, Haglan & Associates, Inc., to provide professional engineering services for the Project after completing a request for proposal solicitation and technical proposal process. Professional Engineering services for the Project include preparing plans, specifications, estimates, structural design and calculations, and technical studies for the replacement of the Marsh Drive Bridge over the Walnut Creek Channel. The professional engineering services also include design support and contractor submittal review during the construction phase of the project.

On September 28, 2019, Dewberry Engineers Inc. (dba Dewberry | Drake Haglan) was assigned the Project’s agreement from Drake, Haglan & Associates, Inc., through an Assignment and Assumption Agreement. This amendment provides for the acknowledgement of the assignment of the County agreement from Drake, Haglan & Associates, Inc., to Dewberry Engineers Inc. (dba Dewberry | Drake Haglan), as well as increases funding to the agreement to $999,309.96, which is necessary for the continuation of design support and contractor submittal review during the construction phase of the contract.

Government Code Section 31000 authorizes the County to contract for services including the Project services that Dewberry Engineers Inc. (dba Dewberry | Drake Haglan) provides.

CONSEQUENCE OF NEGATIVE ACTION:

Without approval from the Board of Supervisors, a delay in construction of the Project will occur, which will ultimately delay the completion of the Project, result in substantial additional project costs and jeopardize the funding.
