文摘

A national programme of research was carried out in Finland to explore a concept for renovation of apartment blocks. The aim of the project was to develop an industrial-scale, economical and efficient concept for renovating, expanding and adding floors to apartment blocks. The technical solutions forming part of the concept make effective use of the opportunity provided by new Finnish fire regulations to use wooden structures when renovating. The apartment blocks built between the 1960s and 1980s now need to be renovated. One alternative that has come to light for the covering costs of renovations is additional construction. Buildings often have flat roofs, which makes the addition of a floor both architecturally and technically easier.

Prefabricated modular units were developed in the project in cooperation with the industry. The size of the units chosen has implications for structural planning as well as for the planning and implementation of the construction site and installation. Prefabricated wood-framed units can be installed on existing concrete slab. The direction and placement of the units are usually determined by the location of the load-bearing structures below. Installation of an array of beams upon the roof of the original building is often the best solution. The beams distribute the load from the new units over the old structures.
