Dr. Lifrieri was retained by a consultant hired by a contractor working for the USACE along the Sprain Brook River Embankment installing stream bank retaining structures. The USACE was concerned about the construction procedures utilized to install drilled shafts and potentially related settlement of adjacent structures. Dr. Lifrieri assisted in the conducting of a Forensic Analysis and Investigations; performed a construction defect analysis; and, helped prepare an expert report concluding that revised drilled shaft techniques would be successful.
