The gushing and fawning by Boston columnists over how quickly Governor Mitt Romney mastered the nuts and bolts of Big Dig information is frightening. I think his new found leadership is a diversion. In a slick show of “control” over the Central Artery Tunnel fiasco, Mitt commands respect with a flick of his magic pointer. The media swoon. It looks like a Boston rendition of Chicago; Bechtel as Roxie Hart kept safe and comfy in the lap of master puppeteer Mitt Romney, playing Billy Flynn. Nice guy, cute guy, downright lovable when he is home pretending he cares, great song and dance man, but there is more going on here than screwing in anchor bolts. Much harder questions need to be asked and investigated by the local media and by independent safety engineers to assure that no more 3-ton ceiling slabs land on commuters or travelers. But, as with any good magic show, Mitt has all eyes trained on the anchor bolts while he tries to convince the public jury that the real fault lies with Matt Amarillo and that Bechtel should be free to just walk out the door.
Just when we thought it was going to be safe to go back in the Central Artery Tunnels in Boston, the Governor let us know that more anchor bolts were faulty in several lanes of I-90 and perhaps in more tunnels. One of the problems with listening to Governor Romney, Turnpike Chair Matt Amarillo or most CA/T predecessors is that they are lawyers and businessmen, not engineers. So take a minute during the Magic Mitt Show to visit the Excavation Company Massachusetts with my tunnel vision because something does not smell right. Even though the laser light is dazzling and the hard hat adds such charm. I’m not ready to clear the deck of the Super Scoop barge for
a decisive victory photo-op.
First, take a really close look at the failed epoxy holding the anchor bolts that suspend the 3-ton concrete ceiling panels. Here are some of the easy to follow instructions for construction workers regarding epoxy-
“Prior to application, all areas must be free of contamination such as waxes, oils, loose concrete, dirt, curing compounds, etc. Acid etching, followed by proper neutralization and rinsing, is usually acceptable if the concrete is in excellent condition, not contaminated.” (Excavation Company Massachusetts ).
Drum Roll-Mitt’s shines a laser light into the dark tunnel and we hear the “ooows” and “ahhhs” over the new, shiny anchor bolts, and a slight of hand trick begins. Will the rabbit now stay in the hole or pop out of the hard hat?
Wake up. Remove your gaze from the anchor bolts and focus on the other end of the suspension rods within the ceiling panels themselves. We see a concrete ceiling with newly tightened anchor bolts on the top and steel cable rods embedded in 3-ton concrete slabs suspended beneath on the other end of the cable. No steel beams exist in the I-90 connector to create the desirable steel-bolted-to-steel infrastructure. So any suspended cable will only behave as well as the concrete on either end allows it to behave. If I put an anchor bolt in a wad of silly putty and hang a rod embedded in 5 lbs. of modeling clay from it…well it’s hanging there with a limited lifespan, I don’t care how new the anchor bolt might be.
