RECOMMENDATION(S):

APPROVE and AUTHORIZE the Chief Engineer, or designee, to execute a contract change order with Four M Contracting, Inc., effective November 2, 2021, in an amount not to exceed $485,887, to be funded out of the approved project contingency for the Lower Walnut Creek Channel Restoration Project, Martinez area. Project No. 7520-6B8285 (District V)

FISCAL IMPACT:

There is no additional financial impact to the construction contract. Funds to cover Contract Change Order No. 14 are available in the approved project contingency. The Project is funded by 45% San Francisco Bay Restoration Authority Grant, 30% Flood Control Zone 3B Funds, 9% Environmental Protection Agency Water Quality Improvement Grant, 9% Bay Area Integrated Regional Water Management Grant, and 7% California Water Conservation Board Grant.

BACKGROUND:

Contract Change Order No. 14 is necessary to pay the contractor, Four M Contracting, Inc., for additional costs incurred as a result of additional excavation of clay soil in the north reach of the project. All contract change orders in excess of $150,000 are required to be approved by the Board of Supervisors.

CONSEQUENCE OF NEGATIVE ACTION:

The lack of approval would prevent successful completion of this contract and prevent payment for the additional work performed by the contractor.
