PART II: PREPARING THE OCTORAD
implosion of The Vet was a true NADC team effort. Chicago-based
Brandenburg Industrial Service Co.'s Bethlehem, PA office bid
the project. They teamed with Franklin, TN-based Demolition
Dynamics, a division of Cincinnati's O'Rourke Wrecking Co.,
to bring the structure down. Rancocas, NJ-based Protec Documentation
Services handled all the vibration monitoring, property inspections,
video, photography and project documentation. All three firms
also participated in an extensive community outreach effort.
General Contractor and new Association member L.F. Driscoll
along with joint venture partner Hunt Construction were responsible
for the construction of both the Phillies' new Citizens Bank
Park and the demolition of Veterans Stadium.
discussion and numerous meetings with local community leaders,
the decision was made to implode the Vet. Brandenburg began
preparing the stadium by performing the necessary preliminary
work several months prior to the implosion date. The utilities
were disconnected, capped, and rerouted throughout the site.
Asbestos contaminating material was removed throughout the stadium
including the galbestos sheeting that existed on the sunshade.
the Vet's famous blue seats were removed and the stadium's hated
Astroturf playing surface was taken up. The Vet's elaborate
underfield drainage system was excavated and the center of the
stadium's playing field would be where Demolition Dynamics would
"place" the Vet's exterior wall.
brought in a fleet of Liebherr excavators with LaBounty processors
to remove the field seating areas. This allowed the remaining
structures to be dropped inward towards the center of the stadium
while allowing room in the center to place a concrete recycling
crusher. Cranes, track loaders, wheel loaders, skid steers,
and manlifts were other types of equipment used on this project.
Exterior ramps leading up to the stadium's gates were removed
prior to the implosion.
project was very high profile and drew many concerns from the
stadium's residential neighbors and adjacent existing sporting
complex. It was imperative for the work to be performed with
little or no disruption to the immediate surroundings. There
were innumerable meetings with the local neighbors to address
all of their questions and concerns.
measures were taken to ensure that the neighborhood would be
protected from noise, vibration, and dust. Brandenburg representatives
devoted considerable time and effort to make sure that the neighbors
were kept well informed of the project's status and all the
necessary precautions were being taken.
teams of inspectors and engineers with Protec Documentation
Services worked in the neighborhood around the Vet for weeks,
documenting existing site conditions, recording project progress
and preparing to monitor the implosion's vibration levels. They
interfaced with local residents on a daily basis, answering
questions and allaying concerns.
member Demolition Dynamics, Inc. planned the implosion for Sunday,
March 21st. The implosion was engineered to take a full 62 seconds
for the structure to completely fall. Using smaller amounts
of explosives in more locations and extending the time delay
significantly reduced the vibration the felling of the Vet would
cause. This in turn reduced the potential for any structural
damage to adjacent homes and sports complexes.
Demolition Dynamics systematically placed 2,518 pounds of 60%
NG product (dynamite) to bring down Veterans Stadium. Five miles
of 25-grain detonator cord and 3,697 detonators were installed.
The detonators covered 382 delays ranging from 17 to 525 milliseconds
each, over the 62-second period - the longest blast ever performed
of a single structure. The
maximum explosive detonated per delay was a mere 12 pounds.
loading the Stadium, one bay was removed conventionally by Brandenburg
to provide space to perform the one-way rotation of the structure.
The Stadium structure would rotate clockwise with the three
elevator towers rotating independently. These elevators were
added during a stadium renovation to provide access to the Vet's
Superboxes located at the top of the facility.
