Roskilde (Denmark)
Roskilde’s demonstration actions focus on the Musicon district, a 200,000 m2 former concrete factory and gravel pit, which Roskilde Municipality (RK) bought in 2003. The ambition is to create a new neighbourhood like no place else. No grand ’master plan’ that locks the development of the area into a specific direction has ever been made. Instead, the different projects are created step-by-step in a collaboration between citizens, developers, architects, cultural institutions, local businesses and the municipality, which means that Musicon is a dynamic site in constant movement and change. In Musicon, existing buildings are being refurbished or demolished and structures, construction materials and soil are being used in new constructions.
Demonstration action 1: Preservation and selective demolition of Hall 11/12
Overview
Hall 11 is a secondary building situated in the demonstration area. It will be demolished and materials from the demolition will be incorporated into other construction projects. The function of hall 12 was and will remain a skate hall. Beams and pillars and the main steel structure of hall 12 will be preserved, with a new roof, façade and interior.
Implementation
- Following a pre-demolition screening a selective demolition will take place using the CityLoops pre-demolition guidelines.
- A virtual material bank will be created through design for disassembly using Building Information Modelling (BIM)
- Circular soil strategies will be implemented by minimising soil movement and facilitating reuse on site.
- Concrete recovered from the demolition will be crushed for recycling into new concrete in the construction of a parking house (demonstration action 2).
