Wetland project receives national award

By March 4, 2015

TRWD has received a “2014 Best of the Best Award” by Engineering News-Record for its work on the recently expanded George W. Shannon Wetlands Project in Navarro County. The project was selected by a panel of national industry experts in the “Water and Environmental” category, which cited the wetland project’s construction and design excellence.

“We are thrilled Engineering News-Record chose our project over so many other qualified candidates from around the country,” said David Marshall, TRWD’s director of engineering and operational support. “The innovate approach used to build this complex project is another example of the district’s willingness to think outside the box when building important water supply projects.”

TRWD used the “Construction Manager-At-Risk” model for the wetlands project, which included having the construction manager participate in the original engineering design process. Because the project was being built in the Trinity River floodplain near Richland-Chambers Reservoir, this allowed the contractor to better understand the potential flooding risks and schedule work during times when flooding was less likely. This construction model kept the work on schedule and helped avoid excessive costs caused by potential delays.

Alan Plummer and Associates was the lead design firm on the project, and was assisted by CH2M Hill. Construction of the wetlands project was completed by McCarthy Building Companies.

The district will be honored by Engineering News Record during a ceremony April 17 in New York City.

*Conservation Level: The permitted level of water an entity is allowed to hold in a lake. Any amount above the conservation level is used for the temporary storage of flood waters and must be released downstream.
**Difference: Amount above or below conservation level.
