The Boston Globe reports that manslaughter charges have been dropped against the company that supplied the epoxy with poor creep resistance implicated in Boston’s Big Dig roof panel collapse that killed one person in 2006, in exchange for a $16M payment to the state and an agreement to stop selling the product. Whoa, it’s still on the market?
The money is slated to fund future Big Dig maintenance costs, but I think a chunk of it should have been earmarked to fund further research and some intense education about the use of epoxy in construction projects and its creep characteristics.
Certainly the National Transportation Safety Board had some scathing things to say about the industry’s working familiarity with epoxy creep: From a report it published in 2007 on the subject, “There is a general lack of understanding and knowledge in the construction community about creep in adhesive anchoring systems.”
More damningly, Bruce Magladry, Director of the NTSB’s Office of Highway Safety, said this in an NPR interview, last year “I don’t think they understood creep at all.”
