Subject

Resolution 2017-33 - Approval of Agreement with Cunningham Construction for Granny White Water Line Connector Project.

Background

The Water Services Department's FY 2017-2023 Capital Improvements Plan includes funding for planned water system improvements throughout the distribution system in order to maintain the highest level of distribution service, reduce maintenance costs and avoid significant future capital costs. Projects are identified using the Department’s distribution system model, along with the asset management program and GIS system, which aid staff in making decisions based on asset age, maintenance cost and historical performance.

For fiscal year 2017-2018, staff has identified for replacement an older section of approximately 1,000 feet of 8-inch plastic pipe along Granny White Pike between Belle Rive Drive and Johnson Chapel Road. This section of pipe was originally installed in 1976. This section also is a connection point between the north and south pressure zones which aids in the transfer of water between the two zones during peak periods of use. Operators control the flow at this connection remotely via the Department’s SCADA/Telemetry system. The section proposed for replacement currently crosses the Harpeth River via suspension from the Granny White Pike bridge, which is the plan for the replacement pipe as well. A site map has been attached for reference.

On April 20 of this year, the City publicly opened construction bids for the aforementioned work. The City received three competitive bids ranging from a low bid of $247,337.75 to a high bid of $385,688.00, not including a contingency allowance. Cunningham Construction and Development, LLC of Nashville, TN submitted the lowest and best bid. Cunningham Construction has successfully completed numerous similar size projects in Brentwood and elsewhere in middle Tennessee over the years and therefore is considered competent to complete this project.

Accordingly, it is the recommendation of SSR Engineers, the project engineer, and the Water Services Department staff that the project be awarded to the low bidder, Cunningham Construction, in an amount not to exceed $272,087.75, which includes the base bid amount plus a 10% contingency allowance. The contract amount is in excess of the project budgeted amount of $175,000. However, the contract amount can be funded through funds available under the Department’s overall capital improvements program (CIP) for water system improvement projects. Project construction is slated for this summer in hopes of completing the work while school is not in session. Staff has attached the project engineer’s letter of recommendation, bid tab and contractor’s bid for your consideration.

Please direct any questions to the Water Services Director.
