Dallas Contracting Co. completes demolition & foundation removals

South Plainfield, NJ— Dallas Contracting Co., Inc. recently completed the demolition of buildings on an active chemical site in New Jersey.

Dallas Contracting demolished a former maintenance building, demolished all associated foundations, removed the surrounding asphalt area and removal of piping on a pipe bridge. The demolition of these items was complicated by being on an active chemical site with live utility (above and below grade) and process lines in the immediate vicinity of work efforts. The plant’s very strict work practices made the endeavor more difficult.

The first task was to remove the old utility and water lines on a pipe bridge that fed to the building. This was accomplished by having laborers on a Genie boom lift cut the lines down with demolition saws. The building and foundation demolition was the next task. A PC 220 excavator mounted with a grapple demolished the structure and a skid steer was utilized to sort and remove debris. The grapple on the excavator was replaced with a bucket to perform the foundation and asphalt removal. A hydraulic hammer attachment was mounted on the skid steer to assist with breaking up the concrete. In addition, laborers utilized a walk behind concrete saw to make cuts in the asphalt and concrete. During the foundation removal, several unknown old sewer and water lines were encountered which were carefully exhumed and removed. Concrete, brick, masonry and asphalt were sent offsite for recycling. Debris was sent off for non-hazardous disposal.

The project was completed in approximately two and a half weeks.
