Report
Summary
The large valve repair and replacement project consists of repair or replacement of 16-inch to 108-inch valves throughout the City's water transmission system. Brown and Caldwell, Inc.'s services will include but are not limited to: project administration; construction inspections; special valve inspections; resident engineering services during construction; repair recommendations; interpretation and clarification of construction documents; and serving as the City's representative during work performed under the job order contract.
This increase in contract value is necessary to continue the inspection and replacement of large valves, because a new valve inspection and maintenance program was implemented in FY 2016-17; small valves are now assessed every three years and large valves every five years. As a result, about four times as many valves than usual were repaired, removed or replaced last year over previous years, in an effort to prevent pipeline leaks and breaks in the long term.
Procurement Information
Brown and Caldwell, Inc., was selected for this project using a qualifications-based selection process according to section 34-603 of the Arizona Revised Statutes (A.R.S.). The City entered into Contract 137454 with Brown and Caldwell, Inc., on March 7, 2014.
Contract Term
The contract had an initial three-year term with one, two-year option to extend. The contract is in year four with an expiration date of March 6, 2019. Contract work scope identified and incorporated into the contract prior to the end of the contract term may be agreed to by the parties, and work may extend past the termination of the contract. No additional contract work scope changes 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 $404,000; and Amendment 1 was approved for a not-to-exceed amount of $290,000, increasing the contract value to $694,000. If approved, Amendment 2 would increase the contract amount by $350,000, for a new total contract value of $1,044,000, including all subconsultant and reimbursable costs. Funds are 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.
