US: Official Warned of Tunnel Ceiling Collapse in 1999

The Associated Press
July 26th, 2006

The on-site safety officer for a Big Dig highway tunnel where a motorist was crushed by falling concrete warned his superiors in 1999 that the heavy ceiling panels might collapse because the bolts could not support them, The Boston Globe reported Wednesday.

John Keaveney wrote in a two-page memo to a senior project manager for contractor Modern Continental Construction Co. that he could not ''comprehend how this structure can withhold the test of time.''

''Should any innocent State Worker or member of the Public be seriously injured or even worse killed as a result, I feel that this would be something that would reflect Mentally and Emotionally upon me, and all who are trying to construct a quality Project,'' he wrote.

In an interview with the Globe, Keaveney said his superiors at Modern Continental and representatives from Big Dig project manager Bechtel/Parsons Brinckerhoff assured him that such a system had been tested and was proven to work.

Andrew Paven, a spokesman for Bechtel/Parsons Brinckerhoff, declined to comment on the report Wednesday.

Modern Continental had no specific comment Wednesday. A spokesman referred to an earlier statement in which the company said it was cooperating fully and was confident the work fully complied with plans and specifications.

The tunnel where the woman was killed is part of Interstate 90 that the $14.6 billion Big Dig project buried under south Boston. It leads to the Ted Williams Tunnel, which runs under Boston Harbor to Logan Airport.

Both tunnels, as well as ramps, were closed to most traffic after the ceiling panels collapsed and inspectors discovered hundreds of problem bolts in their ceilings.

Investigators have been focusing their attention on the bolt-and-epoxy system holding up the ceiling panels, which weigh about 3 tons in the portion of the tunnel where the ceiling collapsed.

Keaveney told the Globe his memo reflected collective concerns among ironworkers installing the ceiling and other Modern Continental employees.

He wrote that the weight of the suspended panels appeared to be ''excessive,'' given that the bolts were ''only inserted into concrete with epoxy.''

He also wrote that while workers were following specifications, he worried that when the state took control of the tunnel, maintenance might be neglected.

''My concerns are for that of the State when they assume control. They have a record of poor maintenance, and I just can envision that these sections will not receive the constant vigilance it would require,'' he wrote.

Keaveney, 43, was paid a salary of $70,000 as the head of on-site safety in the I-90 connector. The letter was mailed to a Globe reporter without his knowledge.

Keaveney said his worry increased a school group from his hometown toured part of the Big Dig project in 1999. He showed them some concrete ceiling panels and pointed to the bolts in the ceiling, explaining that the panels would one day hang from those bolts.

He said a third-grade girl raised her hand and asked: ''Will those things hold up the concrete?''

Keaveney said he shared his concerns with colleagues and then managers. ''It was like the (third-graders) had pointed out the emperor has no clothes,'' he said.
