Report
Summary
The purpose of this project is to augment the City's potable water resources during times of long-term water shortages, emergency outages, and to meet potable system demands. The Water Services Department plans to install three production wells and seven ASR wells; Felix was awarded a contract to drill, install and test five of these wells.
This amendment is necessary due to a scope adjustment request for the water project. After drilling and testing was performed by the contractor, it was determined the pumping capacities were greater than initially estimated by the designer for four of the five wells within their scope. In order to maximize the potential of these wells to augment the City’s water resources, the decision was made to modify them to increase their capacities. This amendment will provide additional time and funds to the agreement in order to complete the modifications to the scope of work.
This amendment is essential to the health, safety, and welfare of the public and critical operations for the City.
Contract Term
The term of the agreement amendment is 30 months from issuance of the Notice to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
- The initial agreement for CMAR Construction Services was executed for a fee not-to-exceed $24 million, including all subconsultant and reimbursable costs.
- This amendment will increase the agreement value by an additional $13 million, for a new total not-to-exceed agreement value of $37 million, which will cover this request and future GMP amendments including all subcontractor and reimbursable costs.
Funding for this amendment is available in the Water Services Department's Capital Improvement Program budget. The Budget and Research Department will separately review and approve funding availability prior to the execution of any amendments. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
