Property description:
The building to be demolished is a school building with a gymnasium. This demolition will be carried out in two stages. The demolition of the existing building complex was a logistical and scheduling challenge. Thanks to the support of the municipality of Zermatt, the logistical problems of the first stage have been solved. The building was separated vertically. Using a large excavator and an extended demolition arm, the first part of the complex with a building around 20 m high was demolished within a short space of time.
The spray mist system mounted on the demolition arm of the large excavator reduced excessive dust formation to a minimum right at the source, which was greatly appreciated due to the density of settlements in the demolition zone.
Some of the demolished material is reused as recycled material, e.g. recycled lean concrete, in the new building. The remaining non-recyclable materials are disposed of in accordance with the applicable regulations.
Requirements:
- Extremely tight space conditions
- Existing wing in full operation
