pohjatyö
Pohjatyö, literally "base work," is a term used in Finnish construction and civil engineering to describe the preparatory works that prepare a site for the main construction. The aim is to create a stable, well-draining, and accessible foundation platform for the structure, and to address any geotechnical or environmental constraints before building begins.
Typical pohjatyö activities include clearing and stripping topsoil, grading and levelling, and excavation to the depths
Project design and local conditions determine the exact scope of pohjatyö. It is typically carried out early
Climate and ground conditions influence pohjatyön approach. In cold climates, frost action is a key consideration,
