Here is the ZR1 Spyder being removed, photo courtesy of the NCM DSC_0304-XL.jpg
Quoting from the NCM Release today: "Last week, the construction team began the tedious process of removing dirt from the sinkhole in hopes of recovering the two missing Corvettes, and to unearth the ZR-1 Spyder which previously only had a portion of the left rear quarter visible. With the aid of a heavy duty vacuum and excavating equipment, the team struck gold - or rather fiberglass - on Friday, March 28 with the discovery of the 1.5 Millionth Corvette.
"When we started digging around the Black Spyder, we found a piece of white fiberglass underneath it and we continued to expose that until we saw that it was the 1.5 Millionth car," said Mike Murphy, CEO of Scott, Murphy and Daniel Construction. "We had no idea where it was, we just happened upon it. We hope when we move the white car we find the red car that way, because we've just not had any luck detecting where it is." Murphy indicated that they have utilized metal detectors as well as probing rods, and that they remove layers of dirt as they probe but have not had a lot of luck so far.
On Monday, the team worked to continue removing dirt from around the Spyder, then in the early evening decided to carefully pull the car out of the remaining dirt.
"It was free everywhere except underneath there was a concrete slab wedged. We felt we had it in the best position, just like pulling a gun out of a holster. Everyone felt like it was best to take it so it wouldn't bend and break if we'd had it exposed more," Murphy said.
The team resumed recovery efforts early Tuesday morning, removing a large boulder that was lodged in the cabin of the Spyder and collecting bits and pieces of the car to help with any restoration or preservation efforts. The Spyder was removed from the depths of the hole around 9am CT, and is in worse shape than even the PPG Pace Car.
"We have always feared that as we dig further into the hole, that the cars would continue to be in worse shape," said Katie Frassinelli, Marketing and Communications Manager. "Unfortunately those predictions were accurate. The 1.5 Millionth has both a large boulder and a concrete slab laying on it. We anticipate that when that car is pulled out, possibly on Wednesday, that it's going to be in even worse shape than the Spyder."
While each sinkhole Corvette has a "story," that of the Spyder is one of the most interesting. The ZR-1 was not a convertible, but GM made only a few prototypes that were. This car was a full performance ZR-1 and was originally painted Sebring Silver with a Neutrino Yellow interior. It debuted at the 1991 North American Auto Show before being repainted black and having the interior changed to red.
"They didn't build a convertible ZR-1 to sell to the public. This is actually a car that General Motors took to different shows to show the car off," said Mike Williams, a member of the Museum's Facility team who's father helped build the car. According to a May 1991 article in Vette Magazine, "The ZR-1 Spyder represents the first time a concept car has ever been assembled on a production assembly line."
The car has many one-off features including custom billett aluminum wheels, a custom tonnau cover with waterfall (an influencer of the C5 Corvette waterfall), a chopped windshield half the normal height, lowered seats mounted directly to the floorpan allowing air to flow around your head, narrowed mirrors, side coves and a louvered hood. Mechanically, the Spyder is a stock 1990 ZR-1.
The underside of the Spyder's hood features signatures of all those involved in building the car. "They have not been able to retrieve the hood. We are still hoping they find it, but that's one of the big problems. When we displayed the car we wanted everybody to be able to see the signatures so when the car went in the hood was up, and it just snapped the hood off," added Williams.
Today, the team will be working to remove the boulder and concrete slab in preparation for removal of the 1.5 Millionth Wednesday or Thursday. The Spyder is now on display in the Museum's Exhibit Hall."

NCM Finds Another Car in the Sink Hole

Looks like they've started digging out one of the missing cars, at least it looks like a car. Can't tell which one it is yet. It doesn't look good. Should be one more missing after they get this one out.

It's the ZR-1 Spyder and it is in very poor condition. Missing the hood signed by everyone and it looks like a few body panels. The cut down windshield is a bit more cut down that it was. But in the process they also said they saw some white fiberglass which would be the 1.5 millionth Corvette. Below is an email the Museum sent out today--Bob

What a gnarly picture.

My thoughts when I saw that were,"the front end is crushed beyond recognition." Then I read the article and found where it says they were "collecting bits and pieces of the car to help with any restoration or preservation efforts" as they dug it out from the hole.

So, I don't want to incite others on a potentially touchy topic, but, in the grand scheme of what is important in life, why would people go to Herculean efforts to try to restore what most would view as a total loss? I do not mean to be offensive, but I really don't understand this.

There are definitely more than a few folks who agree with you, that at least some of the eight cars, perhaps all, should be preserved exactly as they emerged from the sinkhole, not restored.

The seventh Corvette, the 1,500,000th is about to be removed from the sinkhole. It has been freed and will be removed tomorrow. That will only leave the C5 Mallett Hammer Z06 (2001); unfortunately that car has yet to be located. Optimists are hoping it is directly below the 1,500,000th and soon retrieved.

Released today from National Corvette Museum, including this severely injured 1,500,000th Corvette now removed from the sinkhole, and the following press release.


"In less than a week, the 1.5 Millionth Corvette has gone from location unknown to being dug out from the depths of the sinkhole… regaining its status as a display car in the National Corvette Museum on Thursday.

While methods of probing the mounds of dirt in the sinkhole and the use of metal detectors were unsuccessful in finding the milestone Corvette, it was the retrieval process of the Spyder that yielded signs of the first of the two missing cars. “We had no idea where it was, we just happened upon it,” Mike Murphy, CEO of Scott, Murphy and Daniel Construction said.

Upon the removal of the Spyder, the team began working to free the 1.5 Millionth. Initial attempts to pull the car free were to no avail as a large rock appeared to be wedging the rear of the car in the dirt. “Originally, we thought we had to remove the boulder itself to free the vehicle,” said Zach Massey, Project Manager with Scott, Murphy and Daniel Construction, “But we were able to free the 1.5 without addressing the boulder as it turned out it was not directly resting on the car, which was a great advantage to us.”

Wednesday afternoon the team was able to successfully free the car, with final removal from the sinkhole taking place Thursday morning. “While the car appears to be in really rough condition, most of the major components are still there and provides a great base to work off of,” said Adam Boca of the NCM Insurance Agency and a member of the Museum’s Display Committee.

The National Corvette Museum was given the opportunity to purchase the milestone car brand new to preserve its place in history. It was built in Bowling Green, KY on May 28, 2009 and is a white convertible with red interior, a small nod to the first 300 Corvettes built in 1953 in Flint, MI – all being white convertibles with red interiors. The 1.5 Millionth is fully loaded with the 3LT Preferred Equipment Group, Z51 Performance Package, Dual Mode Performance Exhaust, Navigation, 6-Speed Automatic Transmission with Paddle Shift and has a 6.2L V8 engine boasting 430 hp.

The final Corvette to be removed is the 2001 Z06 with Mallett Hammer conversion. “The rest of the day will be spent probing and excavating the area to find any signs of the Mallett Hammer,” said Murphy.

The “sinkhole Corvettes” will come together for a special display in the Museum’s Exhibit Hall through August 3, after which time they will be moved into the restored Skydome where they will remain on display, as-is, through the Museum’s 20th Anniversary Event August 27-30, 2014."

Last sinkhole car found! Good article here:

http://www.stingrayforums.com/forum/stingray-corvette-news/3774-last-corvette-finally-out-here-how-they-did.html

Hope it gets removed soon, and is in better shape than we fear. Once removed, a decision has to be made as to which method of sinkhole "filling" is used. After that is completed, of course, floor structural and perhaps other structural improvements/repairs will be made, then, lastly, the finish floor will be poured. Kudos to NCM leadership, their consultants and staff from Western Kentucky University and their contractors for getting this far in just two months!!!

Amazing, the size of this "sinkhole" equipment. Three "megas" currently at work!




Think they are about to pull the last car out of the hole.

Sad, Sad Ending: Last Sinkhole Car Removed!. Also, upcoming game plan for next steps... The following information was just released by the National Corvette Museum.


"Final Corvette Recovered from Sinkhole: 2001 Mallett Hammer Z06 Ends Quest to Save Museum Corvettes

The last of the "Great 8" Corvettes has been pulled from the depths of the 40 foot wide by 60 foot deep sinkhole that collapsed within the Skydome building of the National Corvette Museum exactly eight weeks ago, marking the end of the first phase of rebuilding.

"We're happy to have the completion of our major goal to recover all eight of the Corvettes," said Wendell Strode, Executive Director of the Museum. "Next week we have a meeting with all the major players, including the construction team, geo-technical firm, cave and karst specialists, engineers, our insurance company and others to review all the findings and have discussions on the next steps and a mutual understanding about rebuilding."

The 2001 Mallett Hammer Z06 was one of two Corvettes that's whereabouts were initially unknown after the sinkhole happened. The car was finally discover this Monday, upside down with the nose pointing towards the red Spire in the center of the room. It is, by far, the most heavily damaged of all eight Corvettes.

"It looks like the worst one... a lot of parts and pieces," said Mike Murphy, CEO of Scott, Murphy and Daniel Construction. "It took a lot of punishment from a lot of big rocks."

The Mallett Hammer was donated to the Museum this past December by Kevin and Linda Helmintoller of Land O' Lakes, Florida, Lifetime Members of the Museum and previous R8C Museum Delivery participants. Upon hearing the car had been located, Kevin traveled to Kentucky to witness the rescue operation. "I expected bad, but it's 100 times worse," he said. "It looks like a piece of tin foil... and it had a roll cage in it! It makes all the other cars look like they're brand new."

Strode had forewarned Helmintoller that the car would be in bad shape and he might not want to watch the recovery process. "Honestly though, I'm still glad I'm here because I would have never believed it was this bad. I'm not positive I would have recognized it - there are just a few little pieces that give it away."

Helmintoller added that he sent pictures of the damaged car to his engine builder, who (jokingly) was quick to point out that the motor was not covered under warranty.

Kevin and Linda spent 13 years modifying the Corvette, a car they purchased new in 2001. The Mallett Hammer conversion was completed in June 2002 and since then has had many AntiVenom LSX Performance modifications with the car boasting 700hp with 575 torque at the flywheel. The car's speed achievements helped it score a cover of GM High Tech Performance magazine.

"We donated this car to the Museum to help with the continued growth, but also because it could be a good vehicle for training other drivers at the new NCM Motorsports Park," Helmintoller said in December upon donating the car.

A “Great 8” display will officially open next week in the Museum’s Exhibit Hall and the sinkhole Corvettes will be available for viewing, as-is, through the Museum’s 20th Anniversary Event August 27-30, 2014."

Here's the latest sinkhole update, facts and...

Here's the reason why the 2001 Mallett was so compacted, as it was directly on top of the car; now park of the NCM landscape.


Interesting Sinkhole Facts (Released today by NCM)

Every sinkhole (in Kentucky) is part of a cave system;
There are 209 documented caves in Warren County;
64 caves in the city limits of Bowling Green;
Traces of gypsum were found which means our cave is thousands of years old;
The current size ent size of the space inside of the sinkhole is 2500 cubic yards."

To give the size of the sinkhole some perspective, 2500 cubic yards would take a convoy of approximately 200 dump trucks to fill it. The team is deciding whether to fill it with "low mobility grout," compacted fill or ? There will be a presentation at the Bash as to "what's next," and even a possible timeline. We have seen a previous release from the Museum that the hole will be filled, the floor re-paved, SkyDome cars returned, and the entire SkyDome open to the public either by or before the National Corvette Caravans arrive (August 27th).

What's Next for the Corvette Museum

Operation Corvette Plus Team Meets to Review Sinkhole Findings, Discuss Skydome Plans
Last Tuesday, team members involved with the National Corvette Museum’s sinkhole recovery and remediation met to discuss the future of the Skydome and construction plan moving forward. Presentations were made of all of the findings, from drillings, to microgravity readings, and the WKU cave and karst team’s exploration into the hole.
Dr. Jason Polk with WKU shared that the void discovered beneath the Skydome extended in two directions– one leading from the Skydome towards the Museum’s truck parking lot, and the other leading from the Skydome towards the pond. Both cave areas start approximately 50 feet underground. According to Dr. Polk, “You don’t typically have sinkholes without caves or voids of some type below them, so this finding was not surprising.” He also indicated that in our area of Kentucky we drive through and around sinkholes and caves every day, with some types of sinkholes even being miles wide. There are dozens of known, mapped caves in the Bowling Green city limits, and over 200 documented caves in Warren County.
Dr. Polk stated that they found mineral deposits which are indicative of dry conditions in the northern extension of the cave. This information means that this portion of our cave is likely thousands of years old and has been there since long before the Museum was constructed. The cave also probably hasn’t had flowing water in a very long time.
The team reviewed the construction documentation from the original building and Skydome. Prior to construction of the building a geo-technical test was completed in accordance with normal standards. They found nothing to indicate any problems. “Normally if there is enough rock, it doesn’t matter what is below it,” said Danny Daniel of Scott, Murphy & Daniel Construction. Daniel also indicated that rebar was not required in the concrete flooring of the Skydome. “It’s no different than the floor of your garage at home. Rebar was not needed to support the weight of the cars in the Skydome,” he added. [EDITORS NOTE: SMD Construction did not build the original portion of the Museum]
The team thinks that our sinkhole was caused by the collapse of a portion of a cave roof, although they are still compiling data. Several things could have caused this, including the extra weight from clay soils above the roof becoming saturated from heavy rain. The team stressed that there is no reason for anyone to be any more concerned for safety here than any other area prone to significant karst development and sinkhole collapse, and it is important to note that much of Bowling Green/Warren County is located in just such an area.
Dr. Polk and Dr. Leslie North, also with WKU Center for Cave and Karst Studies, will be conducting a presentation on Saturday, April 26 at 3:15pm CT on the sinkhole collapse and how it happened. The presentation will be in the Museum's Conference Center.
Moving forward the team is exploring ways to rebuild the Skydome floor. One such plan includes drilling with micro piles then adding beams to ensure the Skydome floor is fully secure. The Museum is also exploring various ideas, which would in some way preserve a portion of the sinkhole, helping to tell the story of what is now Museum and Corvette history. “We will continue to explore these ideas as the process has not moved along far enough to know if keeping a portion of the hole is feasible or not,” said Wendell Strode, Executive Director of the Museum. “The interest in our sinkhole and the rescued Corvettes has been more than expected, and our attendance for March was up 56% over March of last year,” Strode added. “Our special display focusing on this event is now open in our Exhibit Hall. Current plans are to keep the cars on display as they are so that guests through the summer and especially the thousands attending our 20th Anniversary Celebration will have a chance to see the cars and witness the sinkhole for themselves.”
On Thursday the Museum received a donation of a 40th Anniversary “Ruby Red” Corvette. Lynda Patterson of Louisville, Kentucky donated her car in response to the news of the sinkhole swallowing another “Ruby.” The complete release on Ms. Patterson’s car donation is available online here.
Representatives from GM will be meeting with the NCM next month to inspect each of the Great 8 and determine which ones are appropriate to be restored. The Corvettes that are not restored will be kept on permanent display as part of preserving and telling the story of the February 12th Sinkhole Collapse.
