National Corvette Museum Completes Sinkhole Repair

NCM 21st Anniversary Celebration: Skydome Reopens After Sinkhole Repair is Complete

This year marks the 21st Anniversary of the National Corvette Museum, located south of the Bowling Green Corvette Assembly Plant. Since 1994 the museum has undergone significant expansion including the new NCM Motorsports Park that was dedicated last year. The most unexpected event happened to the museum on February 12, 2014 when a large sinkhole opened inside the Skydome and swallowed eight Corvettes. Team Vette did a four-part series on each car that fell into that hole. The news gained worldwide attention, which resulted in a dramatic increase in attendance. After extensive repair work, the Skydome reopened with a ribbon cutting ceremony on September 3, 2015. The repair required extensive use of micro-pilings to ensure this area would never collapse again. Three of the eight Corvettes were repairable (1962 convertible, ZR1 and the 1992 1 millionth convertible). The 1962 will be repaired by the museum and GM agreed to repair the ZR1 and the 1 millionth convertible. The lightly damaged ZR1 was repaired and returned to the museum earlier.

The repaired 1 millionth was unveiled during the Skydome reopening ceremony. That work took place at GM’s Mechanical Assembly and Fabrication Shops in Warren, Michigan. It took 30 craftsman and technicians to complete the restoration. When the car was dismantled the team discovered hundreds of signatures from workers who signed the car during its assembly. They were able to save all but one signature from retired plant employee Angela Lamb. During the ceremony the cover was removed by GM’s John Cafaro and Dave Bolognino and the 1 millionth Corvette looked new. Now retired, Angela Lamb agreed to sign a replacement panel at the ceremony. Dave replaced the signed missing right side gill panel and the restoration was complete.

Katie Frassinelli, NCM’s Marketing/Communications Manager announced that a new “Thunderdome” exhibit will open in November. It will include a multimedia experience that allows visitors to experience the sinkhole first hand. A miniature Skydome is being constructed, where 15 guests at a time can experience a simulation of the sinkhole.

The three day event was packed with seminars that included sessions with past and present Hall of Fame inductees. The presentations included:

• What’s Under the Skydome – Dr. Jason Polk
• Skydome and Sinkhole Repair - Zach Massey
• Meet the New Plant Manager – Kia Spande
• Past and Present Hall of Fame Discussion – HOF Members
• Introduction to the 2016 Corvette – GM Team
• How to Properly Insure your Corvette – Adam Boca

This is a small sampling of the many presentations held during the weekend. In addition, a Celebrity Car Show took place on Friday. Throughout the weekend a High Performance Driving Event was held at the NCM Motorsports Park. For those not racing, shuttles were provided to visitors to observe how Corvettes perform. The GM Team also provided a walk around the 2016 Corvettes and explained its new features. The Labor Day Event is a great way to spend time with other Corvette owners and enthusiasts. It is a relaxing way to spend a Labor Day weekend surrounded by Corvettes and Corvette enthusiasts.

It has a more expansive look and the floor sits on hundreds of micro-pilings attached to the bedrock. Some reach almost 300 feet beneath the floor. The large access door behind the red ZR-1 used for construction, will serve as a maintenance entrance to the Skydome.
