Terracon's Des Moines office is a leading provider of geotechnical and construction materials testing services on transportation projects in the state of Iowa. An example project is the new 5-mile, multi-lane arterial that will connect downtown with US 65 at Pleasant Hill.

Bridge drilling was performed from Terracon's barge-mounted rig. Terracon's scope also includes construction testing of soils and concrete (plant inspections and laboratory testing) and vibration monitoring during pile installation.
