Resolution - Engineering:
Consider a resolution authorizing the Mayor to execute Professional Services Agreement Contract 15977, with Freese and Nichols, Inc., for professional engineering services associated with the Elevated Storage Tank (EST) Design and Pressure Zone Delineation.
Item Summary
A Water Distribution System Master Plan for the City of Lubbock was completed in June 2017. The Master Plan identifies a need for ten million gallons of elevated storage by the year 2034. In order to meet this projected demand, it is recommended that 5 two million gallon elevated storage tanks be installed over the next several years. The City currently owns 3 elevated storage tanks with a total capacity of four million gallons, with three million gallons in the west pressure zone, and one million gallons in the east pressure zone. The existing elevated storage tanks are below the City’s current and future hydraulic grade line (HGL) and therefore cannot be relied upon as functional storage capacity.
The Texas Commission of Environmental Quality (TCEQ) requires 100 gallons of elevated storage per connection, resulting in a future need for four million gallons of elevated storage capacity on the east pressure zone, and six million gallons on the west pressure zone, for a total of ten million gallons across the City. These storage tanks will also provide an opportunity to optimize pump station efficiencies within the City of Lubbock, reducing electric, operations, and maintenance costs as well as providing pressure during power outages. In order for these elevated storage tanks to function properly, the City must establish and delineate the pressure plane between the east/west pressure zones. The initial review of the pressure plane that runs along Indiana Avenue has revealed that there are inoperable valves and valves that cannot be located along the boundary. This project will include the replacement or rehabilitation of broken valves and installation of additional piping where a proper pressure zone cannot be established within the current system.
Staff recommends award of the professional service agreement to Freese and Nichols, Inc. of Fort Worth, Texas, for $955,522.62. Time for substantial completion is 365 calendar days from the Notice to Proceed.

This contract is in the amount of $955,522.62 and is funded in Capital Improvement Projects 92452, Elevated Storage Tanks and 8622, Pressure Zone Delineation.
