An interesting project involving the renovation of a small three-storey hotel. During the renovation, the attic floor was completely rebuilt, giving the building a modern appearance and a more functional layout.
As the initial reference data, we received a scanned point cloud model of the existing building in E57 format. Based on this data, the geometry was analyzed, and a precise model of the new superstructure was created — ensuring exceptional accuracy, which significantly improved both the speed and quality of installation.
Main Part Design OÜ was responsible for:
Development of the structural BIM model, including electrical sockets and conduits
Structural calculations, including overall building stiffness and structural connection analysis
Production drawings, including part and assembly drawings
Production specifications and shipping lists
General arrangement drawings
Structural Overview
Load-bearing exterior and interior timber-frame walls
Roof structure: gang-nailed plate rafters with roof truss overhangs
The building’s stiffness was ensured by transferring the roof diaphragm loads to the walls, which acted as shear walls, and further to the underlying concrete structure through the action of the structural sheathing.
Glulam stiffening frames with concealed steel plates, joined with dowels and bolts, were installed in the panoramic window area
Wall diaphragms are anchored using the Rothoblaas system hold-downs and chemical anchors
