Attorney general’s office settles with two firms in fatal Big Dig collapse

Settlements with two more companies involved in building the Big Dig tunnel that collapsed in July 2006 have been reached, the Massachusetts attorney general’s office announced on March 26.

Attorney General Martha Coakley announced the settlements with Gannett Fleming Inc. in Camp Hill, Pa., and Sika Corp. in Lyndhurst, N.J.

In a statement, Coakley said she wanted to resolve all matters relating to the collapse “in a manner that was fair and just for the Commonwealth, and for the loved of [tunnel collapse victim] Milena Del Valle who so tragically lost her life almost three years ago. We believe that we have achieved that goal."

Gannett Fleming, designer of the section of the I-90 tunnel ceiling that collapsed, will pay a total of $1.575 million to the state and city of Boston. It will also forgo $150,000 in payments from the Massachusetts Turnpike Authority.

Sika made the glue used in the ceiling and will pay $200,000 to the state.

The attorney general's office dismissed claims against Sigma Engineering International Inc. and Conam Inc., saying the companies were not liable in the collapse.
