Report
Summary
The purpose of this project is to construct new water and wastewater infrastructure for potential growth in the area of Phoenix north of the Central Arizona Project canal, south of Carefree Highway, west of I-17 to the City of Phoenix city limits. The City anticipates the work may be done in multiple phases depending on development progress. Phase One includes four packages advertised and awarded separately. Phase One water and wastewater infrastructure includes a Pressure Reducing Valve (PRV) station, water transmission mains, booster pump station, lift station, force mains, and large diameter gravity sewer mains. Phase One work was divided into four packages as follows:
- Package One: PRV Station at 51st Avenue and Carefree Highway; 51st Avenue Corridor (gravity sewer and 54-inch water transmission main); 16-inch water main along Carefree Highway from 51st Avenue to North Valley Parkway; 6B-B1 upgrade from 15 Million Gallons per Day (MGD) to 25 MGD.
- Package Two: 12 MGD Lift Station Northeast of Loop 303 and 51st Avenue.
- Package Three: Water and Wastewater mains north of Loop 303 Corridor and Sonoran Desert Drive to North Valley Parkway, including a 36-inch water transmission main, three 24- to 36-inch sewer force mains, and one gravity sewer main west of I-17.
- Package Four: 60-inch Gravity Main in North Valley Parkway or alternative route to Lift Station 66.
Garney Companies, Inc. (Garney), Felix Construction Company (Felix), Sundt Construction, Inc. (Sundt), and McCarthy Building Companies, Inc. (McCarthy) will all begin in agency support roles for CMAR Preconstruction Services. The contractors will assume the risk of delivering the projects through Guaranteed Maximum Price (GMP) agreements. A Small Business Enterprise goal will be established for this project during preconstruction services and reviewed prior to the start of construction.
Garney, Felix, Sundt, and McCarthy will then transition to preparation of GMP proposals for the Construction Services provided under the agreements, and participate with the City's Small Business Enterprise (SBE) program. The contractors will be responsible for construction means and methods related to the project and fulfilling the SBE program requirements. The contractors will be required to solicit bids from prequalified subcontractors and to perform the work using the City's subcontractor selection process. The contractors may also compete to self-perform limited amounts of work.
The Contractors' services for both preconstruction and construction services include but are not limited to: design and constructability reviews; providing cost estimates and developing cost models; procuring long-lead items; preparing a GMP proposal; and constructing the first phase water and wastewater infrastructures.
These agreements are essential to the health, safety and welfare of the public and critical operations for the City.
