Project information

  • Location: Dewey Beach, Delaware

  • Client: Delaware Department of Transportation

  • Services: Underwater Engineering; Design Services

Boswell Engineering’s team of engineers and divers Installed a Scour Monitoring System which was designed and fabricated by the University of Delaware with Boswell’s professional collaboration during the design phase. The primary component of this system utilizes a sonar device to gauge the progression of developing scour holes that could potentially de-stabilize the bridge piers located in the water. Boswell was designated by the Delaware Department of Transportation (DelDOT) to provide professional underwater engineering services necessary to precisely install the system sensing devices on the seaward side of the two in-water piers below mean low water in an environment normally hostile to divers. Also included in Boswell’s scope of work was the installation of fendering frames above the sensor brackets to protect the sensors from boats abutting the pier stems.

With the implementation of such a system, DelDOT now has an added measure of safety for motorists using the bridge. BOSWELL ENGINEERING was the recipient of a Distinguished Project Award from the American Council of Engineering Companies of New Jersey for this assignment.
