Report
Summary
The purpose of this project is to evaluate and replace aging water mains within the City of Phoenix. The primary focus of the program is to replace prioritized mains that have reached the end of their useful life and have been identified as having high break rates. Work for these projects typically includes installing or relocating fire hydrants. Coordination with City staff and plumbing contractor regarding relocation of water services may also be required.
This amendment is necessary because upon review of the scope and cost, it was agreed that estimates were too low and the pricing from J Wise is fair and in line with current market value. This amendment will provide additional funds to the agreement.
Contract Term
The term of the agreement amendment remains unchanged at 334 calendar days 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 was approved for CMAR construction services with a fee not-to-exceed $3,957,900, including all subconsultant, subcontractor, and reimbursable costs.
- Amendment 1 will increase the agreement value by an additional $1,172,512, for a new total not-to-exceed agreement value of $5,130,412, 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.
