They were the Big Dig's largest contractor and are in Chapter 11 bankruptcy because federal prosecutors brought 49 charges against them including allegations that it knew about bolts coming loose in the ceiling of the Big Dig tunnel years before a ceiling collapse killed a motorist.
Shouldn't there be some kind of lifetime ban on them doing engineering work?
I doubt they're getting any new contracts, anyway, ban or no, especially now that they're in bankruptcy. The problem is there's a whole backlog of stuff they did years ago before anything major happened to suggest their work was problematic. As you note, this water supply tunnel was finished in 2003, while the Big Dig ceiling collapse fiasco didn't happen until 2006.
Something similar happened in Atlanta, where two structures built by Hardin Construction collapsed within a year, a pedestrian bridge in 2008 and a parking garage in 2009. I doubt they were getting much new business after that first collapse in 2008, but that still left a bunch of existing work, like the GT parking garage, already out there.
