SR23 First Coast Expressway

GRL Engineers was the SR23 project's Dynamic Testing Engineer (DTE) for the 26 bridges on 10.5 miles of new multi-lane limited access toll roadway to State Road 23, part of the First Coast Expressway. Prior to construction, a GRLWEAP pile driveability study was performed for initial hammer selection. Dynamic pile testing and monitoring was performed using a Pile Driving Analyzer and results were assessed with CAPWAP software to establish production pile driving criteria.
