RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with CDM Smith Inc., (CDM) effective June 26, 2018, to increase the payment limit by $200,000 to a new payment limit of $400,000, and extend the termination date from July 6, 2018, to December 31, 2019, for continued on-call water treatment consulting services, as recommended by the Public Works Director, Countywide.

FISCAL IMPACT:

100% County Service Area M-28 funds

FISCAL IMPACT: (CONT'D)

BACKGROUND:

The Public Works Department is involved in various projects in the County which require water treatment engineering services. After a solicitation process, CDM was selected to provide water treatment engineering services on an “on-call” basis. The consultant will augment Public Works Staff on an as-needed basis. The consultant will be used when in-house expertise is not available.

The contract was originally solicited and awarded July 7, 2015. Currently, CDM is working on the design memorandum for County Service Area (CSA) M-28, Willow Mobile Home Park Water District, Bethel Island. The design memorandum will address the abandonment of the existing reverse osmosis treatment system and an existing well. The design memo will also discuss proposed improvements to the water treatment system so as to continue meeting primary drinking water standards and to maintain system operability. Once the design memorandum is completed, CDM will prepare the bid package for the upgrade of the CSA M-28 treatment plant.

CONSEQUENCE OF NEGATIVE ACTION:

If the contract amendment is not approved, there is a possible delay in completing projects requiring water treatment services, such as the upgrade of the CSA M-28 treatment plant.
