Report
Summary
The purpose of this project is to construct new wastewater infrastructure for potential growth in the area north of the Central Arizona project canal, south of Carefree Highway, west of Interstate-17 all the way to the City of Phoenix limits.
This amendment is necessary because additional work was required by the Contractor to complete lift station construction and commissioning including addressing revisions between the 90 percent drawings, conformed construction documents, addition of a discharge header, and underground piping, which added the option and flexibility to pump to the south.
Felix Construction Company's additional services include, but are not limited to: asphalt paving, subgrade preparation, concrete flatwork, site finish grading, structural excavation, site signage, shade canopy installation, programming, influent manhole revisions, additional wire and conduit, and the addition of a discharge header and underground piping.
Contract Term
The term of the agreement remains unchanged. 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 Construction Services was approved for an amount not to exceed $22 million, including all subcontractor and reimbursable costs.
- This Amendment will increase the agreement by an additional $4,947,779, for a new total amount not to exceed $26,947,779, 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.
