Extension of commercial building in Vilnius,  Saltoniskiu str. 29. Client needs to build extra 2 floors on the top of existing 3 floor building, but the facade of it should not be covered with scaffolding and the structure must be assembled in 10 hours.

Prorentus engineers chose to use the new Layher Lightweight FW bridge system in this project. This new system allows designing scaffolds for service with large spans. This is the first construction site in the Baltic states to use this system. The 6 m. span was used here, because of the limited bearing capacity of custom made supports for the scaffolds.
