Report
Summary
The purpose of this project is to replace the existing finished water pump station (FWPS) at the Deer Valley Water Treatment Plant (DVWTP) to provide resiliency for the water system and increase the plant's pumping capacity to supplement water in the northern portions of Phoenix's water service area. The City of Phoenix Water Services Department completed a study that identified infrastructure improvements to move water in the distribution system, as needed, in the event there are restrictions placed on Colorado River water delivered through the Central Arizona Project (CAP). The City of Phoenix treats CAP water at the Union Hills and Lake Pleasant WTPs, which supply water to north Phoenix. Following completion of the project, the new pump station at the DVWTP will be able to augment water supply in areas that have typically received water from the City's CAP plants. In order to replace the FWPS, it will be necessary to move the existing chemical storage and feed facilities at the FWPS. The first phase of the project includes the relocation and demolition of the chemical facilities which has been completed. The second phase includes construction of the new FWPS which is approximately 50 percent completed.
This amendment is necessary because of miscellaneous unforeseen onsite and changing market conditions during construction.This amendment will provide additional funds to the agreement.
Contract Term
The term of the agreement will remain unchanged. 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 Construction Manager at Risk (CMAR) Services was approved for an amount not to exceed $85 million, including all subcontractor and reimbursable costs. This amendment will increase the agreement by an additional $3.5 million, for a new total amount not to exceed $88.5 million, including all subcontractor and reimbursable costs.
Funding 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 execution of any amendments. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
