Report
Summary
The purpose of this project is to replace approximately 1.6 miles of 48-inch pre-stressed concrete cylinder pipe with new 48-inch diameter steel pipe constructed in a new alignment. The new alignment extends north from the 24th Street Water Treatment Plant along 20th Street to Orangewood Avenue.
Kiewit's initial services will include preparation of a Guaranteed Maximum Price (GMP) proposal for the Construction Services provided under the agreement and participating with the City in a process to establish a Small Business Enterprise (SBE) goal for the project. Kiewit will be responsible for construction means and methods related to the project and fulfilling the SBE program requirements. Kiewit will be required to solicit bids from prequalified subcontractors and to perform the work using the City’s subcontractor selection process. Kiewit may also compete to self-perform limited amounts of work.
Kiewit’s services include, but are not limited to: construction of the selected alignment design per final plans and specifications; bond and insure the construction; address all federal, state and local permitting requirements; arrange for procurement of materials and equipment; schedule and manage site operations; address owner issues; maintain a safe work site for all project participants; and provide quality controls.
Procurement Information
The selection was made using a qualifications-based selection process set forth in section 34-603 of the Arizona Revised Statutes. Scoring and selection were made in conjunction with the CMAR Preconstruction Services selection process.
Contract Term
The term of the agreement is 675 calendar days 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.
