Providing timely updates on the Corvette sinkhole incident has always been a priority for the Museum. In an effort to provide everyone with as much information as possible, Mike Murphy with Scott, Murphy and Daniel, our Construction Management company, has written an update as to the work that has been completed and the plan for work moving forward.
We’ve named the project this because for something to raise from a base level
‘up’ equals moving in a ‘+’ direction. Our ultimate goal is to keep the
existing building ‘up’ in its original position, raise the Corvettes in the
hole ‘up’, then bring the fill in the hole ‘up’ and lastly, bring the concrete
floor back ‘up’ to its original level.
We are very
appreciative of the National Corvette Museum, Chubb Insurance and VanMeter
Insurance Group to allow us to assemble the best group of professionals to
effectively and accurately ‘heal this horrendous hole’ in the Skydome.
Our reputation both in business and personally, obligates us to hold the best
interest of our community partner in mind 24/7 until the project is completed.
PLUS” ESTIMATED SCHEDULE
Since the beginning of the project, the number one goal is to ‘proceed
cautiously ‘ with the recovery and reconstruction in such a manner to keep
safety of the facility and the workers the main priority and number two,
plan and perform in a positive (+) direction daily. Because there
are so many unknowns within the boundaries of this project, having an exact
schedule ‘in stone’ is not practical or possible. Every day’s planning
and action determines the next step in executing a successful operation.
We began the week finishing shallow test borings in the remainder of the
Skydome floor to insure there was no immediate danger of another sink hole
collapse happening in the remaining floor space. These tests proved
equipment such as manlifts, excavators and cranes (which are on site and ready
to approach the sink hole area) could be brought into the Skydome area, deeper
test drilling was performed to insure a sufficient thickness of earth and rock
was present to support this equipment’s entry and operation. The last test hole
was completed Wednesday morning and the ‘positive data’ recorded has now been
turned over to the engineers and geologists for their analysis and
verification. Additionally on Wednesday, drillers moved their operation to
the outside foundation of the Skydome and have begun the drilling,
high-strength grouting and installation of steel cased micro piling connected
to the dome’s perimeter foundation. This operation, securing and reinforcing
the building’s foundation, will continue for approximately 1 ½ to 2
we received ‘the go ahead’ by the professionals to give the ‘green light’ to
bring equipment into the area and begin the set-up and preparation for the
cranes to suspend engineers and contractors safely into the middle of the sink
area and examine closer the condition of the hole and finalize the recovery
plan, determine exact measurements for lifting and verify techniques for
beginning the removal of the ‘three’ most assessable vehicles (those not
embedded into the embankment). The mobilizing of equipment and accessories,
along with the final planning and hole condition examination should finish this
week’s work schedule through Saturday, as the outside piling installation continues.
There is a suspended steel ring around the spire in which the lighting and
sprinkler system is located. A quick test run on Wednesday is indicating the
possibility to disconnect the system and raise it above the needed working area
of the crane booms. This could possibly cause a day’s delay in the recovery
operation should this be determined once cranes are in their designated
keep in mind that a special operation such as this cannot be on an ‘exact
planned schedule’ like a new building under construction is often
orchestrated. Concerns and calculations which insure the safety of the
building and workforce will remain our #1 priority, even if it impedes our
schedule to insure that each task is performed exact and successful.
We anticipate if all
plans and factors work successfully, the removal of the first three vehicles
will begin during the day on Monday, in hopes to have all three cars extracted
by Wednesday. The first car to be removed is the 2009 ZR1 "Blue
Devil." There may be some complications when removing the 1962 Black
Corvette because the 5 ton concrete slab resting against the front of the car
must be lifted simultaneously and in conjunction with the lifting of the
vehicle. We will be allowing approved media to film INSIDE of the Skydome
during the first car's removal.
