The four walls of a detached house in Porvoo are being demolished using different methods – How can demolition be cost-effective while remaining intact?

(For clients.) A special demolition site will start in Porvoo in a week. The white-painted, timber-framed detached house is no longer suitable as a home. There is a meter of water in its basement, and the apartment is no longer functioning for its original purpose. However, the Porvoo house will still get to play the main role in a unique demolition pilot. Each wall of the house will be demolished using a different method. Faster than manual work The first wall will be demolished traditionally, i.e. quickly and with large machines. The wall materials will be crushed into pieces for waste pallets. The second wall will not be crushed into pieces right away, but the wall boards and frame structures will be removed more manually than the first wall. The proportion of manual work and the range of methods will increase in the demolition stages of the third and fourth walls. Each stage will be timed. As the demolition progresses, the quickest and most functional, and at the same time most cost-effective, ways of working will be tried and found. After the last wall, it would be known which method is the fastest but potentially the most destructive. There would also be an understanding of how the material can be recovered intact, and whether it will take too long from an economic perspective. In the future, a combination of these methods may be the most effective. A rare demolition site The demolition pilot is being implemented by a large group of partners.
