Gresham, Smith and Partners announces that Dale Mosley, senior vice president in the firm’s Water + Environment market, presented a case study on the Cumberland City Low Transmission Water Main improvements completed by GS&P at the 2018 Kentucky/Tennessee Water Professionals Conference on July 9 in Nashville. Alongside Garney Construction’s Jeff Seal, Mosley discussed how the project, which was completed in just 24 months, provides resiliency and efficiency for Nashville’s water system.

“The Cumberland City Low project provided significant challenges in relation to routing and construction, but we developed creative solutions that kept the project on its expedited delivery schedule,” commented Mosley. “I enjoyed sharing the lessons we learned with attendees at this year’s Kentucky/Tennessee Water Professionals Conference.”

A summary of the presentation follows.

Nashville’s Largest Water Line Project: From Concept to Service in 24 Months
Presentation by Dale Mosley and Jeff Seal

America’s aging infrastructure has been pushed into the spotlight, with much of the emphasis placed on the condition and performance of the country’s roads, bridges and transportation systems. Less visible but equally important, America’s drinking water infrastructure is also approaching the end of its predicted life cycle.

In the case of water main transmission improvement projects, one of the best ways to increase resiliency is through reliability achieved through redundancy. A prime example of this best practice in action is the Cumberland City Low (CCL) Transmission Water Main project in Nashville, Tennessee, a project that comprised more than 26,000 linear feet of ductile iron water main, including more than 24,000 linear feet of 60- and 36-inch diameter and 2,000 linear feet of 12-inch diameter. The outcome of the project was a dual-feed water transmission main for an essential portion of Nashville’s water distribution system with quantifiable social, environmental and economic benefits.

In this presentation, GS&P’s Dale Mosley and Garney Construction’s Jeff Seal discussed the collaborative process between Metro Water Services, Metro Nashville Public Works, the Tennessee Department of Transportation, Gresham, Smith and Partners, and Garney Construction that led to the completion of a successful project on an expedited schedule. Additionally, the duo shared how the team navigated the project’s challenges and complexities to create system resiliency and redundancy while taking a triple bottom line approach.
