Dallas Contracting Co. Completes Salvage Project

Dallas Contracting Co. Inc. has completed the demolition of an industrial facility in the northern part of its home state of New Jersey.

The approximate 5-acre industrial site, which was formerly used for manufacturing, was composed of five buildings and other miscellaneous structures. The buildings to be demolished were one to two stories in height and the total footprint was more than 50,000 square feet. The building construction was a mix of steel frame and wood frame, brick and block walls and wood roofing with asphalt shingles. Dallas Contracting’s scope included demolition of all buildings and structures including foundations, removal of debris and metals, asbestos abatement and onsite sizing and crushing of concrete masonry and brick for future use as backfill.

The site will eventually be redeveloped for residential use.

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

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. Lights and ballasts were collected using ladders and electric lifts, placed into shipping containers and shipped offsite for recycling. Containers of oils and grease were also collected in 55 gallon drums and disposed offsite. Asbestos abatement activities included abatement of pipe insulation, roofing transite siding and tiles.

Demolition commenced once the environmental hazards were addressed. 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 and a Komatsu PC300-5 mounted with a grapple, a Fiat wheel loader and several Cat 236 skid steers. Demolition included all above grade structures and also all slabs, foundations, footings and other miscellaneous surface and concrete structures. Approximately 250 tons of steel were sent offsite for scrap metal recycling.

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 material was then fed into the company’s concrete crushing plan, an UltraMax 100-15CV plant with stacking conveyors from Eagle Crusher Inc. Approximately 5,000 tons of concrete, block and brick was crushed, which was used onsite for backfill.
