More efficient demolishing with digital solutions
We developed digital solutions to promote more efficient demolition of buildings and reuse of demolished parts together with Green Net Finland, Metropolia University of Applied Sciences and the Finnish Environmental College SYKLI.
Carbon emissions from construction can be reduced, and resource consumption moderated by reusing materials and components from demolished buildings. The new Construction Act, which has entered into force at the beginning of 2025, takes into account the carbon emissions of construction and introduces new practices in the sector, making greater use of digitalisation. We participated in Digipurku – Digital solutions for building demolition project, led by Green Net Finland, where we developed digital solutions for collecting, organising and sharing information on demolition sites to promote more efficient demolition for the reuse of demolished parts.
Digitalisation can be used to enhance and streamline the processes of reusing building components. HAMK was especially responsible for developing the advanced procurement methods for building demolition, as well as investigating the potential for robotising the scanning of demolition sites. The sustainability criteria were considered in the advanced procurement method and an excel tool was developed for industrial use. Robotic scanning was found to improve scanning efficiency and speed up an otherwise time-consuming process by up to 30%.
Robotic scanning systems automate route planning and optimise the selection of scan points for building scanning. The robot can then autonomously traverse the site and generate data for further work. The robots can also work at night, for example, making the scanning process much more efficient.
The system we developed during the project could have the potential to become a fully automated scanning system. By promoting technological integration in construction and design, we are paving the way for a smarter and more sustainable future.
Digipurku was a joint project of Green Net Finland, Häme University of Applied Sciences, Metropolia University of Applied Sciences and the Finnish Environmental College SYKLI. The project was co-funded by the European Regional Development Fund’s Renewable and Competent Finland 2021-2027 programme.
