Under a Construction Manager at Risk (CMAR) partnership with the North Texas Municipal Water District and Freese and Nichols, Garney quickly became an integral team member in the delivery of the Lake Texoma Outfall to Wylie WTP Raw Water Pipeline. In an effort to complete the majority of work on this 46-mile stretch of pipeline in less than 24-months, Garney was responsible for managing 20 contractors and overseeing the installation of 206,000 LF of 96” steel pipe, 47,500 LF of 84” steel pipe, 240 MG balancing reservoir, a 200 MGD blending facility, and a multitude of ground storage tanks, metering, and chemical feed systems to allow the treatment plant to accept and blend the water directly from the source.
Construction on the project, set to be complete in mid-summer, was prompted upon growing population, coupled with periodic severe drought conditions, and required the North Texas Municipal Water District to have full access to its surface water stored in reservoirs on a permanent reliable basis. When one of the District’s key storage reservoirs was infested with zebra mussels, the District’s ability to access the water stored in the reservoir and transmit to the reservoir local to their treatment facilities was limited by the federal government. This meant a new transmission and storage method was required for the District to access 28% of its total capacity.
Constructing this $309 million project under the CMAR process was pivotal to the project success and expedited schedule. A project of this magnitude was the first of its kind for Garney.
