About the Project

Casella Construction, Inc. was contracted to deconstruct the Cook Science Building for the University of Vermont. The building was located in the heart of the campus and 20 feet from their newly constructed ‘Discovery Building’.

CCI started the project by self-performing the interior demolition and removing all building components down to the cast-in-place concrete structure. Construction and demolition (C&D) materials were brought to a C&D recycling center for additional processing. Ferrous and non-ferrous metals were processed onsite and packaged for resale within the interior of the building.

Mass demolition began by preparing the exterior facade and roof. CCI removed all roof-mounted equipment, membrane roofing, stripped the brick veneer, and removed a layer of 2” rigid insulation between the brick and concrete masonry units (CMU). The brick was separated for recycling and reuse as aggregate. The preparation of the structure was critical to achieving our recycling rate of 99.5%, higher than the required rate of 90%.

CCI used a high-reach excavator with a multi-processor supported by various hydraulic excavators. Dust was managed with a water mister that could reach up to 300 feet away. The mass demolition was completed in 8 weeks, allowing the next phase of construction to begin ahead of schedule.

Highlights

  • CCI separated 400 tons of C&D from the structure
  • CCI recycled 1,10 cy of cast-in-place concrete
  • CCI processed 145 tons of ferrous and non-ferrous materials for resale
  • CCI worked with AO to preserve a 36’ x 48’ portion of the foundation

About the Project

Casella Construction, Inc. (CCI) was contracted to preserve the recreational, educational, and environmental assets of Ascutney Mountain.

The 24,000-sf building was comprised of a cast in place concrete foundation, steel frame, concrete masonry unit (CMU) curtain-walls, and wooden clapboard siding. CCI separated the building materials into appropriate waste streams for disposal and recycling. CCI separated 400 tons of construction and demolition material (C&D) from the structure, recycled 1,100 cy of cast-in-place concrete, processed 145 tons of ferrous and non-ferrous metals for resale. The recycled concrete was crushed to a 4-inch minus materials used as a portion of the backfill for the foundation.

CCI completed the project in four weeks while working with the owner to preserve and protect a 36-foot x 48-foot portion of the existing foundation. This portion of the foundation will support a new base lodge and multi-use space for the owner and the local community.
