The project

The smaller building, on the other hand, was constructed using precast framing that supported a precast roofing system. A railway spur line, located immediately to the north of the buildings, had to be protected from any damage during the project.

Prior to the commencement of demolition operations, Delsan-A.I.M. undertook the abatement of asbestos-containing materials, which consisted of drywall joint compound, sprayed on fireproofing insulation, vinyl floor tiles, ceiling panels, and transite pipes, as well as the removal of other hazardous materials, such as mercury-containing fluorescent light tubes and polychlorinated biphenyls (PCBs) that were found to be present in exterior wall caulking.

The project involved the decommissioning and demolition of a large, single storey warehouse with an area of 432,000 ft2 and an overall height of 24.5 ft., along with a single storey ancillary building with a footprint of 2,300 ft2 and a height of 15 ft. The main building, which also included some mezzanine floor structures, consisted of steel framing with a metal deck roof supported by open-web steel joists and exterior walls made of precast panels.

Delsan-A.I.M. then proceeded with the interior selective demolition of architectural, mechanical, and electrical building components in order to better source-separate the different waste materials prior to commencing bulk demolition operations.

Delsan-A.I.M. completed the demolition of the buildings using large excavators equipped with specialized attachments in accordance with engineered guidelines. The final stage of the project involved the demolition and removal of the footings and foundations, which were subsequently crushed using an in-house mobile crusher.

All the demolition materials were shipped off-site to licensed recycling or disposal facilities in accordance with the applicable regulations including 1,900 tons of scrap materials, while the crushed concrete, which totaled approximately 32,000 tons, was stockpiled on the project site for future reuse by the owner.
