Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 149652 with RFI Consultants, LLC to provide additional Engineering Services for the Sub-Regional Operating 91st Avenue Wastewater Treatment Plant Pipe/Equipment Coating 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 for rehabilitation and replacement of existing protective coatings on wastewater infrastructure at the 91st Avenue Wastewater Treatment Plant. Equipment, pipes, manholes, and various other process structures at the plant require coatings to help protect infrastructure from the harsh wastewater environment. In order for these coatings to be effective they require routine maintenance. The continual upkeep of protective coatings enhances and extends the life of the infrastructure.
This amendment is necessary due to a re-prioritization of construction funding that delayed the project. This amendment will provide additional time to the agreement.
The 91st Avenue Wastewater Treatment Plant is owned by the Sub-Regional Operating Group (SROG) and operated by the City of Phoenix.
Contract Term
The term of the agreement amendment is two 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.
Financial Impact
The initial agreement for Engineering Services was approved for an amount not to exceed $500,000, including all subconsultant and reimbursable costs. There is no Financial Impact associated with this amendment.
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.
