Description
Request to authorize the City Manager, or his designee, to execute Amendment No.1 to Contract 143212 with Felix Construction Company (Coolidge, Ariz.) to provide Construction Manager at Risk (CMAR) Construction Phase Services in support of the Deer Valley Water Treatment Plant (WTP) Aquifer Storage and Recovery (ASR) Well Program. Further request authorization for the City Controller to disburse all funds related to this item.
Report
Summary
The project consists of construction of an Aquifer Storage and Recovery Well. This type of well can pump water up from the aquifer when water is needed for supply. It also can pump water down into the aquifer during low-demand periods to store water, which can then later be pumped back up during high-demand periods. The well has been drilled and the project is moving forward into the phase of constructing the well head and installing equipment necessary to operate the well.
The CMAR will assume the risk of delivering the project through a Guaranteed Maximum Price (GMP) contract. The CMAR will be responsible for constructing the infrastructure for the Deer Valley WTP ASR Well, procuring materials and equipment, scheduling and managing site operations, providing quality controls, and managing all construction-related contracts while meeting City bid requirements, including local and Small Business Enterprise (SBE) participation goals. An SBE goal of eight percent has been established for this contract.
Procurement Information
Felix Construction Company was chosen to provide CMAR services for this project using a qualifications-based selection process 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 143212 was executed in July 2016 for Felix Construction to provide initial construction phase services to solicit pricing information from its subcontractors and suppliers, including self-performed work, and to submit its GMP proposal for the project. The incorporation of the GMP construction pricing through a contract amendment was anticipated as part of the project development process.
Contract Term
Services for this project are expected to be completed within 329 days from issuance of the 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. No additional contract work scope may be executed after the end of the contract term.
Financial Impact
The initial contract value was established at a not-to-exceed amount of $21,232 to provide GMP Preparation Services. The contract capacity will be increased by $2,580,826.61, for a new contract value of $2,602,058.61, including all subcontractors and reimburseable costs. Funding for these services is available in the Water Services Department's Capital Improvement Program budget. Contract payments may be made up to the contract limits for all rendered contract services, which may extend past the contract termination.
