Work to repair the sinkhole damage at the National Corvette Museum remains on track as construction entered its third week in Bowling Green Monday.
The Skydome is still expected to open again in July.
First, though, workers on Monday were using two pieces of equipment to remove rocks from the sinkhole, one of which was a limestone boulder the size of a small car. They drilled metal clips into the rock to help their effort.
Katie Frassinelli, marketing and communications manager at the NCM, said officials have recently made a last-minute decision to install a 36-inch manhole to leave access into the cave even after the sinkhole is filled.
“We did have some ideas of future exhibits where you could see out into the cave and have a camera with some lights in there, maybe some car parts,” Frassinelli said. “Then guests will be able to control the camera and look inside the cave.”
A one-foot-thick layer of concrete will be poured first on the floor of the sinkhole so workers can then lay horizontal piling in an attempt to seal off all of the voids and seal the outside of the cave itself, according to Joe Schultz, project superintendent for Scott, Murphy & Daniel.
“On the top side looking down, it’s a whole lot simpler,” Schultz admitted. “You don’t realize the immensity of it.”
Interestingly enough, workers say it’s warmer now in the sinkhole than it is on the ground.
“When you get down in there you can feel the moisture and the heat. Not really the per se heat. It’s really around 55 degrees. It’s about the same in here, but you can feel the moisture coming up in there,” Schultz said.
