Forensic engineering has come a long way since Wiss Janney Elstner Associates was featured on the cover of ENR in 1972. For its 150th anniversary, ENR looks back at how problem-solving and investigations by that forensics firm and others have better informed the engineering knowledge base.
A 1972 ENR cover story said of Wiss Janney Elstner Associates in Northbrook, Ill., “It exists largely by looking for trouble, both before and after the fact of structural distress and failure.”
Former Wiss, Janney Elstner principal tackled structural challenges from material deterioration to brittle fractures and collapses of steel buildings and bridges.
