Purpose and Recommended Action
Recommendation
This is a request for City Council to authorize the City Manager to enter a Construction Agreement with Achen-Gardner Construction, L.L.C. (Achen-Gardner) for construction services for waterline replacement at three locations and approve the expenditure of funds in an amount not to exceed $299,959.body
Background
The city’s water distribution system is a vast network of water mains, service lines, valves and fire hydrants which foster the conveyance of potable water for domestic and fire protection purposes. There are over 994 miles of water lines, including 24,000 valves, 62,000 service lines and 8,400 fire hydrants.
Moving water through the city’s distribution system is a key component in ensuring uninterrupted service and reliability. Proactive rehabilitation and replacement efforts minimize maintenance issues, emergency disruptions and assist with maintaining the integrity of the water distribution system. The project is part of an on-going proactive preventive maintenance effort to maintain the operational reliability of the city’s water distribution and fire suppression systems.
The project is needed to install three (3) water mains and one (1) water service line at unique locations city-wide. Currently the existing water lines are undersized and do not meet the current design guidelines and fire flow requirements. The locations include; 53rd Avenue to 54th Avenue on Wescott Road, 79th Avenue to 79th Drive on Carol and the Chase bank service line at 67th Avenue and Peoria. Additionally, the project includes the installation of a new waterline at 67th Avenue and Corrine for SRP Well Site (22) which was relocated by SRP. This will allow the City to pump water from the groundwater Well into the City water distribution system.
Analysis
A Notice to Contractors was issued on February 2, 2017 by the Engineering Department to provide construction services for waterline replacement and new waterline installation at three locations throughout the City. Seven (7) firms submitted bids and Achen-Gardner was determined to be the lowest bid.
Previous Related Council Action
On November 22, 2016, Council approved a professional services agreement with Wilson Engineers, LLC, for design and construction administration services at SRP Well 22.
On April 12, 2016, Council approved a professional services agreement with Strand Associates, Inc. for design and engineering services for fire hydrant and waterline valve replacements and three sections of undersized water lines.
Community Benefit/Public Involvement
The project will enhance the integrity of the water distribution infrastructure, minimize pipeline breakage, service interruptions, and improve water quality.
Budget and Financial Impacts
Funding is available in the adopted FY2016-17 and the proposed FY2017-18 capital budgets. Future year budget appropriation is contingent upon Council approval.
