Affholder Inc., a subsidiary of Insituform Technologies Inc., hasreceived an award for outstanding contract performance from the U.S. Army Corpsof Engineers, St. Louis District.

The company received the U.S. ArmyCorps of Engineers award in recognition of its work on a sewer rehabilitationproject for Metropolitan Sewer District of St. Louis. The Army Corps ofEngineers made federal funding available to MSD to cover approximately 75percent of the $4 million project.

The project included rehabilitation of3,168 ft of pipe extending along Vandeventer Ave. to Grand Avenue in south St.Louis. The project encompasses grouting, installation of a concrete invert andapplication of shotcrete to the existing sewer to fill voids and repairconnections. Portions of the sewer constructed more than 100 years ago are 14 ftwide by 12 ft high, up to 18 ft wide by 15 ft high.

The award recognizedAffholder’s quality control testing, which exceeded the specificationrequirements of the project. Also recognized were Affholder’s compliance withlabor standards and effective safety management. The project involved 50,000working hours, which Affholder completed with no lost-time accidents.

“Itis a significant accomplishment on any project to have 25 workers working 50,000hours with no lost-time accidents,” said Mike Badgley, area manager forAffholder. “Everyone who worked on this project deserves recognition for thesafety performance.”

The original job bid was for structural repairsonly. After work began, however, the Corps of Engineers determined that onesection of the sewer required a stand-alone structural insert to providesufficient reduction in the possibility of a future collapse. The time allowedfor the project was extended to allow for construction and placement of thestand-alone component. Affholder completed the project within the revisedschedule.
