Following the ship’s impact, collapse, and subsequent repair of the main span of the Eggner Ferry Bridge, the Kentucky Transportation Cabinet initiated plans for its eventual replacement. Part of the design phase included an extremely comprehensive load test program, of which AFT served as the primary load testing firm.

AFT served as the specialty engineer performing extensive pre-test planning and design before load testing. This work included numerous wave equation studies, vibration studies, pre and post-test program crack surveys on the existing adjacent bridge.

AFT performed remote vibration monitoring, PDA, CAPWAP, static load test monitoring, both lateral and axial STATNAMIC™ load testing throughout this expansive project. The test piles included H-piles and various diameter steel pipe piles with lengths of over 200 feet. Static load testing was performed to 3000 tons, and STATNAMIC™ load testing was performed to 5000 tons.

The sheer scope and diversity of this load test program resulted in many academic studies, including the use of steel piles in the US and numerous published journal papers.
