Investigators fault epoxy 'creep' in Big Dig collapse
Article Abstract:
Investigators from the National Transportation Safety Board (NTSB) concluded that the use of an epoxy anchor adhesive was the cause of the collapse of 10 ceiling panels in the D portal connecting Interstate 90 in Boston to the Ted Williams Tunnel, which is part of the Big Dig project. The NTSB raised issues on how the epoxy came to be used and why inspections were not carried out even after signs of displacement or "creep".
