Case Studies - DC Water (District of Columbia Water and Sewer Authority) Project

A Seton key account manager, located at the company's Branford, Connecticut office, played a key role in getting the right pipe markers for the job. He received details of the project from the superintendent at MEB General Contractors Inc., and began immediately to coordinate efforts to get these pipe markers produced and delivered to the jobsite. An operations manager on the Seton team in Buffalo, New York helped construct special jigs to create two different sizes of especially large pipe markers that measured 32™ wide and 39™ tall and 24™ wide and 26™ tall.
