can be slightly higher.
Several factors contribute to the cost-effectiveness:
- ideal conditions for digital planning thanks to high prefabrication
- short construction time
- earlier commissioning/renting/sale
- lower heating costs
- lower maintenance costs
- lower deconstruction costs
Correlation of life cycle costs and construction method
Those who want to consistently implement the requirements of BöB and SIA 101 will in future rely on high quality and the sustainable use of resources. sustainable use of resources. The use of wood is the logical consequence.
Use of Swiss wood in public tenders
