Sinkhole Remediation at the National Corvette Museum

Investigation and Treatment of a Swallvette

* Loosely derived from Merriam Webster “swallet + corvette”

Corvettes in sinkhole

Hayward Baker is the largest geotechnical specialty contractor in the country providing services to all types of clients in all types of ground conditions. This one hour presentation discusses various aspects of the sinkhole collapse at the National Corvette Museum in Bowling Green, KY. However, it is not a highly technical analysis or case study. Rather, it gives due respect to the historical significance of the vehicles impacted by the collapse and includes bits of geology, history, engineering, anecdotes, photos, comedy, lore and an infatuation with America’s sports car.

At 5:38 am on the morning of February 12, 2014, security cameras recorded the collapse of the display floor and development of a sizeable sinkhole inside the museum. Eight treasured and unique corvettes were “swallowed” by the cavity. Within 24 hours, a team had been assembled to stabilize the area, assess the short term risk, evaluate procedures to safely remove the automobiles, and develop a plan for exploration and permanent repair; essentially “vetting” solutions to the complex issues.

Team members represented a wide range of professionals representing construction, engineering, surveying, geology and environmental consultants, academic experts and state geotechnical and safety officials. Data acquisition included large diameter drilled holes, laser surveys, micro gravity study, physical cave exploration, borehole cameras and literature research.

All of these aspects were executed amidst worldwide attention and media chaos. Live webcams were installed, hourly Facebook postings, YouTube videos and about every other avenue of communication known to man were employed.

Every aspect of study and repair entailed moderate to very high degrees of risk in all categories. The expertise and determination of the team conquered all of the obstacles in as timely a manner as possible attempting to maintain economical approaches whenever possible.
