Dallas Contracting Co. Completes Demo Job

Dallas Contracting Co. Inc., South Plainfield, N.J., recently completed the demolition of the former Paul O. Abbe facility in Little Falls, N.J.

Dallas Contracting was contracted by TRC Environmental Corp. to demolish the entire facility, including slabs, foundations and footings. The facility consisted of six multi-story buildings with a footprint of nearly 100,000 square feet. From a redevelopment standpoint, the site will eventually be turned into a residential development.

The first task was to disconnect all utilities in order to isolate the facility. Dallas Contracting coordinated the disconnection of water, gas, electric, sewer, phone and cable utility lines.

The next priority was to address the environmental hazards present at the facility, which included lights and ballasts, miscellaneous containers of oils and greases, and the abatement of asbestos containing materials.

Lights and ballasts were collected using 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 recycled offsite. Asbestos abatement was also conducted and included abatement of pipe insulation, roofing, flashing and tiles.

Once the environmental hazards were addressed, building demolition commenced. To complete the demolition of the facility, Dallas Contracting used numerous pieces of equipment that included a Komatsu PC-400-LC6 mounted with a Labounty rotating shear, a Komatsu PC-400 mounted with a concrete pulverizer jaw attachment, a Komatsu PC300-5 mounted with a grapple, a Komatsu PC200-LC6 mounted with a grapple, a Fiat wheel loader and several Cat 236 skid steers. Demolition included all above grade structures, slabs, foundations, footings and other miscellaneous subsurface concrete systems. Approximately 500 tons of steel were sent offsite for scrap metal recycling.

Following demolition of the buildings, the concrete, block and brick material needed to be crushed to a 2-inch minus for use as onsite backfill. Dallas Contracting first sized the material into 2-foot diameter or less using a Komatsu PC-400 mounted with a concrete pulverizer and a Komatsu PC-300 with a hydraulic hammer attachment. The sized material was then feed into the company’s crushing plant, an UltraMax 1000-15CV Plant with stacking conveyors from Eagle Crusher. Approximately 8,000 tons of concrete, block and brick were crushed and used as backfill onsite.
