Brown County Culvert Replacement

An existing concrete box culvert located in Brown County, Kansas, was in poor condition and in need of replacement or significant repair. Initially, the county considered several different options. At one point, the County was presented with an option of replacing the existing concrete box culvert with a one-piece culvert complete with prefabricated headwall manufactured by Contech Engineered Solutions LLC. Ultimately, the County determined that an Aluminized (ALT2) HEL-COR® 5x1 CMP solution with a prefabricated headwall would be an ideal solution.

There were several factors that ultimately lead to this decision and the selection of an ALT2 HEL-COR® culvert. First, Contech's 5x1 HEL-COR and attached headwall offered a solution that would resolve known scour issues at the site while meeting the county's stringent budget requirements. Secondly, the headwall design allowed the county to create and directly attach wingwalls made of Contech Metric Sheeting to the headwall providing additional benefits and ease of installation. Contech's custom manufacturing and flexible headwall design assistance offered the county precisely what it needed for a specific site condition. Lastly, manufacturing the pipe and headwall as a unified structure facilitated quick installation by county forces. 

At the conclusion of the replacement, Brown County was extremely pleased with the results. A total of only 120 man hours were required for the complete installation, saving the County a significant amount of time and money to complete the total replacement of the original, failing concrete box culvert.
