Spray Booth, Oven and Process Equipment
Strip Out & Demolition
Strip Out and Demolition of Paint Shops and Process Equipment, including
Warren, MI and Moraine, OH
Owner: General Motors
Process Equipment Demolition: Warren Transmission
Plant, Warren, MI - This project consisted of final clearing
of approximately 440,000 square feet of process area located in
General Motors Corporation’s Warren Transmission Plant.
Over the years the plant went through many changes without any
prior removals. The United States Navy and the Hudson Motor Car
Company constructed the facility in 1941 for the manufacturing of
various types of artillery and shells. The facility was subsequently
owned by Westinghouse and Ford Motor Company, before it was purchased
by the Chevrolet Motor Division of General Motors in 1961. From
1961 to 1974, the facility was used to manufacture automotive parts
and artillery shells. From 1974 to July 1980, Chevrolet continued
automotive manufacturing operations. The Hydra-Matic division of
General Motors began operations in 1980 and continues to produce
transmissions and various other automotive parts to this day.
It was the task of North American Dismantling to finally clear
out all the old and redundant systems that had been collected over
the years, including electrical, mechanical, fire protection, heating
and ventilating, and security systems. There were absolutely no
as built drawings available to assist North American Dismantling
in this endeavor. Several of hundreds of hours were spent identifying
and labeling the systems that were to remain and those that were
to be removed.
All abandoned pipes, conduits, wires were removed from the inside
and below the roof truss of the buildings. Conveyors, mezzanines,
catwalks, and their supports that were no longer in use were removed
completely. All equipment support brackets were removed. Steel
brackets and clamps for pipes and conduits were removed from roof
trusses and building columns in the identified dismantling area.
American Dismantling removed all old equipment structural members,
u-bolts, and hangers connected to roof trusses in all areas.
Additionally, North American Dismantling removed 45,000 square
feet of wood block flooring, 56,000 sf of concrete pavers, and 244,750
sf of non-monolithic concrete (including topcoat, concrete pads,
concrete curbs, and equipment foundations). The wood block flooring
and brick pavers were removed and disposed of as regulated materials
and the areas below scarified to received new concrete topping.
North American Dismantling also removed several hundred feet of
48” round ductwork, which covered an area of approximately
200,000 sf from the existing roof.
North American Dismantling completed the asbestos abatement of
pipes, heater units and HVAC units located in the truss of the buildings.
North American Dismantling also completed the environmental cleaning
of all pits, sumps, flooring and trenches in all areas.
In addition to our original contract work, North American Dismantling
was awarded the removal of approximately 12,000 sf of existing oven
from the roof area. The ovens were contaminated with non-friable
ACM. In Addition, North American Dismantling received the proper
40 hr training that was needed to remove the ovens. The roof, roof
panels, and side panels of the Elpo Oven were double wrapped with
6-mil poly and disposed of as ACM. The remainder of the oven was
removed as non-hazardous metal and debris. Because of the high flammability
of the roof, North American Dismantling, in conjunction with the
Plant Fire Marshall, purchased four plasma cutters and trained its
employees to complete these operations.
Process Equipment Demolition Paint Shop Spray
Booth and Ovens: Moraine, OH - This project consisted of
the removal of approximately 50,000 sf of paint ovens and 10,000
sf of paint spray booths located on the second floor and grating
level of the plant directly adjacent to the operating paint shop.
There were several factors that made this a very complex and unique
Aside from being located directly adjacent to the
paint shop, the second floor and the grating level were built over
the old roof (R-1 Level) of the existing assembly plant with an
active assembly line located directly below the roof area. The use
of water for fire protection had to be minimized and all openings
in the R-1 level had to be protected to prevent any foreign mater
from entering the assembly area. Also, active paint conveyors were
located on the R-1 level directly below the demolition area which
had to protected from the demolition operations. Absolutely no dust
or foreign matter could come in contact with these systems.
Another hurdle to overcome involved having no major
access and egress to the demolition area until NADC designed and
installed a series of structural steel bridges consisting of 60
tons of material connecting the demolition areas to a drop zone
at the edge of the existing building. This operation required opening
the existing building in five separate areas and installing a weather
protection system to eliminate any elements from entering the plant.
The construction of these bridges included airlifting structural
members utilizing helicopters, which was completed on plant down
time (Sundays and Holidays).
North American Dismantling was also responsible for
the design/build of $1,200,000.00 of the structural steel/grating
and concrete utilized in filling all openings where the booths and
ovens were removed, along with utility disconnects, rerouting and
re-supporting and the relocation of existing process equipment.
Additionally, during the course of its contract GM
requested North American Dismantling remove an existing 240-foot
long, 80-foot wide and 80-foot tall Automatic Retrieval System (Stacker
Building). This structure was connected on two sides and was 30
foot taller then an existing building, which was to remain.
This project was completed on schedule, with limited
change orders and without interference to the plant’s existing
