Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 155550 with Garney Companies, Inc. to provide Construction Manager at Risk Construction Services for the Cave Creek and Lone Mountain Waterline Connection project. Further request to authorize execution of amendments to the agreement as necessary within the Council-approved expenditure authority as provided below, and for the City Controller to disburse all funds related to this item. The fee for services will not exceed $4,850,000.
Report
Summary
The purpose of this project is to construct approximately one mile of new waterline to connect between existing infrastructure south of Carefree Highway and the new 10A-B1 Booster Pump Station (BPS). Approximately one mile of new waterline will also be constructed along Lone Mountain Road for system resiliency when the BPS is operational.
This amendment is necessary because of the change in cost due to market escalation and additional time due to unanticipated construction issues. This amendment will provide additional funds and time to the agreement.
Contract Term
The term of the agreement amendment is for an additional two years 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. No additional changes may be executed after the end of the term.
Financial Impact
The initial agreement for Construction Manager at Risk Construction Services was approved for an amount not to exceed $14,050,000, including all subcontractor and reimbursable costs. This amendment will increase the agreement by an additional $4,850,000, for a new total amount not to exceed $18.9 million, 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 execution of any amendments. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
