Report
Summary
The purpose of this project is to design approximately 21,500 linear feet of 16-inch Ductile Iron Pipe transmission main within Pressure Zone 3C in the Town of Paradise Valley, and a new Pressure Reducing Valve Station (PRV) proposed to be located within Pressure Zone 4A on an existing City of Phoenix retention basin property on the southwest corner of Shea Boulevard and 45th Place. This will relieve Booster Station 3C-B1 and Well 235, which are located southwest of Invergordon and Doubletree Ranch roads. The new 16-inch transmission main will connect to the existing 16-inch transmission main within Shea Boulevard.
This amendment is necessary to include funding for CA&I services for the project. This amendment will provide additional funds and time to the agreement. This agreement 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 248 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 for Engineering Services was authorized for a fee not-to-exceed $1.3 million, including all subconsultant and reimbursable costs.
- Amendment 1 will increase the agreement by an additional $472,531, for a new total not-to-exceed agreement value of $1,772,531, including all subconsultant and reimbursable costs.
Funding for this amendment is available in the Water Services Department's Capital Improvement Program budget.
