RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with Hultgren-Tillis Engineers (Hultgren-Tillis) to increase the payment limit by $15,000 to a new payment limit of $265,000, for on-call geotechnical engineering services, with no change to the term March 1, 2016 through December 31, 2019, Countywide area. (Project No. Various) (All Districts)

FISCAL IMPACT:

Work performed under this amendment is funded by 100% Local Road, Flood Control Funds and Airport Enterprise Funds.

BACKGROUND:

The Public Works Department is involved in various projects in the County which require geotechnical engineering consulting services for road, flood control, and airport projects. After a solicitation process in 2016, this firm and four other firms were selected to provide geotechnical engineering services on an “on-call” basis. On March 1, 2016, a consulting service agreement with Hultgren-Tillis was approved by the Board of Supervisors.

BACKGROUND: (CONT'D)

Since the original consulting service agreement was executed, the Consultant provided on-call geotechnical engineering services on multiple projects. While most of these projects were completed, the San Pablo and Wildcat Creeks Levee Certification and Grayson and Walnut Creeks Levee Rehabilitation at Central Contra Costa Sanitary District Treatment Plant Projects in San Pablo, Martinez and Walnut Creek were on-going and required Consultant’s engineering services beyond the original Agreement’s March 1, 2019 expiration. In order to allow these projects to continue without disruption, the contract was extended through December 31, 2019, by Amendment No. 1 solely for the completion of these projects.

Proposed Amendment No. 2 will amend the payment limits in order to provide payment for additional geotechnical engineering services that were needed to successfully complete the projects.

CONSEQUENCE OF NEGATIVE ACTION:

The Consultant would not be paid for services rendered.
