Resolution - Engineering: Consider a resolution authorizing the Mayor to execute Change Order No. 1 to Contract 15477, with Garney Construction, for construction of the Low Head C Supply Pipeline along 26th Street.
Item Summary
The purpose of this project is to construct a supply pipeline to transport treated water from the South Water Treatment Plant to existing Pump Station 16. The Low Head C Supply Line will connect the Low Head C Pump Station to the existing Bailey County Well Field Supply Pipeline and to existing Pump Station 16. This project is part of the Strategic Water Supply Plan adopted by City Council on February 28, 2013.
Change Order No. 1 to Contract 15477 includes Proposed Contract Modifications (PCM) 001 through 003 as well as Work Change Directive (WCD) 001. These changes include adjusting the pipe alignment in order to provide installation cost savings to the City, replacing a 24-inch waterline near abandoned Pump Station 7 that will ensure the new Low Head C Pipeline will be able to fully function as designed, and adding traffic-rated valve vaults along 26th Street in order to protect the new Low Head C infrastructure now and in the future.
Fiscal Impact
Change Order No. 1 in the amount of $450,102.12, is funded in Capital Improvements Project 92450, Low Head C Supply Line and Pump Station.
