Dallas Contracting Co., Inc. Completes Demolition of Former GAF Facility

The approximate 11 acre industrial site, which was formerly used to produce roofing and siding shingles, was composed of over 10 buildings and various other structures including a water tower and several vertical above ground storage tanks. The footprint of the buildings to be demolished was over 170,000 square feet. From a redevelopment standpoint, the site is a designated brownfield site that will eventually be turned into a residential development. The front buildings were steel framed with transite siding whereas the rear older, multistory buildings consisted of concrete and wood floors, brick and block walls and wood roofing. Dallas Contracting's scope included demolition of all buildings and structures including foundations, removal of all debris and metals, asbestos abatement and onsite sizing and crushing of concrete, masonry and brick for future utilization as backfill.

The first task was to disconnect all utilities in order to isolate the facility. Dallas Contracting coordinated the disconnection of water, gas and electric utility lines. Several electric transformers also required removal and proper disposal.

The next priority was to address the environmental hazards present at the facility. The environmental hazards included lights and ballasts, miscellaneous containers of oils and greases, and the abatement of asbestos containing materials. Light and ballasts were collected utilizing ladders and electric lifts, placed into shipping containers and shipped offsite for recycling. Containers of oils and greases were also collected into 55 gallon drums and disposed offsite. Asbestos abatement activities were conducted by The Mack Group, LLC and included abatement of pipe insulation, roofing, transite siding and tiles.

Demolition then commenced once the environmental hazards were addressed. To complete the demolition of the facility, Dallas Contracting utilized numerous pieces of equipment that included a Komatsu PC-400-LC6 mounted with a Labounty rotating shear (MSD-70R), a Komatsu PC-400 mounted with a concrete pulverizer jaw attachment, a Komatsu PC300-5 mounted with a grapple (also used with a shear attachment), a Komatsu PC200-LC6 mounted with a grapple, a Fiat wheel loader and several Cat 236 skid steers. The site crew averaged 10 personnel which consisted of equipment operators and laborers. Demolition included all above grade structures and also all slabs, foundations, footings and other miscellaneous subsurface concrete structures. Approximately 1600 tons of steel were sent offsite for scrap metal recycling.

Several of the older buildings had a substantial amount of salvageable wood which was predominantly yellow pine. Dallas Contracting carefully dismantled the wooden sections of these buildings to salvage the Yellow Pine timbers, beams and posts. The salvaged wood was then stacked, banded and sent to a wood salvage company where they were remilled into wood flooring. In total, Dallas Contracting salvaged approximately 40,000 board feet of wood.

Following demolition of the buildings including the slabs and foundations, the concrete, block and brick materials needed to be crushed to 2 inch minus for use as onsite backfill. Dallas Contracting first sized the materials into 2 foot diameter or less by using a Komatsu PC-400 mounted with a concrete pulverizer and a Komatsu PC-300 mounted with a hydraulic hammer attachment. The sized materials were then fed into Dallas Contracting's concrete crushing plant. Dallas Contracting owns an Eagle Crusher Company, Inc. UltraMax 1000-15CV Plant with stacking conveyors. Approximately 30,000 tons of concrete, block and brick were crushed which was used onsite for backfill. This was a dual benefit to the client as they did not have to pay to send the materials offsite for recycling and they did not have to pay for imported backfill material.

The project began in April 2004 and was completed the first week of December 2004. The project was completed without incident or injury.
