Lift Station 66 Refurbishment - Engineering Services Amendment - WS90400084 (Ordinance S-50367)
Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 151303 with Garver, LLC, to provide additional engineering services for the Lift Station (LS) 66 Refurbishment 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.
Report
Summary
The purpose of this project is to refurbish LS 66. The lift station was initially constructed and operated to provide direct flows to Cave Creek Water Reclamation Plant (CCWRP). When the CCWRP was shut down in 2009, LS 66 flows were bypassed to the gravity sewer in North Valley Parkway with the exception of flows from the adjacent City of Phoenix Solid Waste Transfer Facility.
In order to make LS 66 operational, upgrades and improvements are recommended for the mechanical, structural, electrical, instrumentation and control system equipment. The proposed refurbishment project includes replacement or upgrades of pumps, motors, slide gates, piping, valves, bio filter, variable frequency drive, programmable logic control, control panel, instrumentation, and coating refurbishment.
This amendment is necessary as the construction portion of this project will not be started until late January 2024 and additional time is needed for Garver, LLC's services to continue.
Garver, LLC was the firm selected to do the design and construction administration inspection for this project. Garver, LLC's additional services include, but are not limited to: assisting the City during the procurement phase by providing responses to questions from bidders, oversight of the project construction activities, inspecting the site through various stages of construction, reviewing contractor work submittals, performing field inspections where required for completed repairs, finalizing contract documents including electronic submittals, as-builts, and a water asset management engineering packet.
Contract Term
The term of this agreement amendment is three years 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
There is no financial impact to this project.
