This crap just keeps getting better and better…
A Big Dig technician says he witnessed critical bolt failures in the mid-1990s during installation of Ted Williams Tunnel ceilings and started photographing construction because of concerns about a possible disaster.
The technician, whose job was to test the strength of ceiling fixtures, revealed shocking photographs to the Herald yesterday that show workers in the Ted Williams Tunnel using methods to install epoxy bolts that were flagged as problematic by inspectors.
One of the technician’s photographs shows laborers installing bolts in a way that drew two stern warnings from the oversight firm Bechtel/Parsons Brinckerhoff in 1995. (emphasis added) The picture shows workers applying epoxy to a screen that is then inserted into a bolt hole, a method typically used for a different type of construction, records show.
We’ve covered this already in the past here and here.
This points to deeper problems in the way we do things beyond simple party politics and sloppy work.
