Report
Summary
This project is part of the Water Main Replacement Program to evaluate and replace aging water mains within the City of Phoenix. This amendment is for additional CMAR Construction Phase Services in Areas 1 and 2. For Area 1, work will include replacement of 6-inch and 8-inch water mains, fire hydrants, and service connections, and related work. For Area 2, work will include replacement of 4-inch, 6-inch, 8-inch, and 12-inch water mains, fire hydrants, fire lines, and service connections, and related work.
J. Wise Corporation will assume the risk of delivering both projects through a Guaranteed Maximum Price (GMP) contract. J. Wise Corporation will be responsible for construction means and methods related to the project, participating with the City in a process to set a local and Small Business Enterprise (SBE) goal for the project, and implementing the SBE process. A Small Business Enterprise goal of 7 percent has been established for the contract. J. Wise Corporation will also be required to solicit bids from prequalified subcontractors and to perform the work using the City’s subcontractor selection process. J. Wise Corporation may also compete to self-perform limited amounts of work.
Procurement Information
J. Wise Corporation was selected to perform CMAR Construction Phase Services for the two projects based on a single procurement according to section 34-603 of the Arizona Revised Statutes. Scoring and selection were made in conjunction with the CMAR Design Phase Services procurement process.
Contract Term
The term of the contract amendment to include CMAR Construction Phase Services is expected to be 11 months from issuance of Notice to Proceed. Contract work scope identified and incorporated into the contract prior to the end of the contract may be agreed to by the parties, and work may extend past the termination of the contract for work in progress. No additional contract work scope changes may be executed after the end of the contract term.
Financial Impact
The initial contract for GMP Preparation Services under the CMAR Construction Phase Services contract for projects in Areas 1 and 2 was executed for a fee not-to-exceed $10,000, including all subcontractor, supplier, and reimbursable costs. This amendment would increase the contract value by an additional $2,667,947 and $2,801,623, for Areas 1 and 2 respectively, for a total increase in contract value of $5,469,570. This increase would result in a new total contract value of $5,479,570, including all subcontractor, supplier, and reimbursable costs.
Funding for this amendment is available in the Water Services Department's Capital Improvement Program budget. Contract payments may be made up to contract limits for all rendered contract services, which may extend past the contract termination.
