About this award
The U.S. Army Corps of Engineers, Pittsburgh District awarded a $7.24M firm fixed-price contract to Marion Hill Associates, Inc., a small business contractor based in New Brighton, Pennsylvania, for the Upper Guidewall Stabilization project at Dashields Locks and Dam in Coraopolis, Pennsylvania. This 100% small business set-aside contract has an ultimate completion date of May 11, 2026, and addresses critical infrastructure maintenance along the Ohio River. Marion Hill Associates will execute a comprehensive stabilization effort that includes constructing stone buttresses on both sides of the Upper Guidewall, performing test borings to assess subsurface conditions, and installing geotechnical instrumentation including piezometers and inclinometers for ongoing monitoring.
The project scope encompasses riverine construction operations from a floating plant platform, with work focused on the waterward side of the existing Upper Guidewall structure. Marion Hill's responsibilities include erosion and sediment control management, completion of specified river and hillside boring operations, buttress construction both instream and on landward areas, and installation of automated monitoring instrumentation that will be maintained by the contractor during the project timeline but transferred to the Corps of Engineers upon completion. The contractor must also manage proper disposal of construction spoils at commercially permitted facilities. This award reflects the Corps of Engineers' ongoing commitment to maintaining critical waterway infrastructure and locks and dams throughout the Ohio River Basin through targeted stabilization and monitoring initiatives.
