Title
16-Inch Paradise Valley Zone 3C Improvements - Construction Manager at Risk Services Amendment - WS85500418 (Ordinance S-50283)
Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 152069 with Hunter Contracting Co. to provide additional construction services for the 16-Inch Paradise Valley Zone 3C Improvements project. Further request to authorize execution of amendments to the agreement as necessary within the Council-approved expenditure authority as provided below, and for the City Controller to disburse all funds related to this item. The additional fee for services included in this amendment will not exceed $6.5 million.
Report
Summary
The purpose of this project is to construct 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 Station to relief Booster Station 3C-B1 and Well 235.
This amendment is necessary because the project was delayed due to high costs of pipeline construction and difficulties with obtaining easements for access to the proposed Pressure Reducing Valve Station. In addition, it will ensure that both phases of the project can be completed. This amendment will provide additional funds and time to the agreement.
Contract Term
The term of the agreement amendment is five years from the 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.
