School Building in Sutz-Lattrigen, Switzerland

The school building addition in Sutz-Lattrigen was built on the existing foundation floor. This foundation was not designed to withstand a second story. Therefore, the loads from the first floor and the additional second story had to be designed as concentrated loads.

Indermühle Bauingenieure from the Swiss town of Thun was responsible for the timber engineering during the project phase, from the preliminary project to the supervision of the final design. The firm also completed the 3D project planning on behalf of the timber construction company. RFEM was utilized for the structural analysis.

Structure

The additional floor consists of floor-to-ceiling trusses in the longitudinal and transverse directions. The truss diagonals are glued-laminated timber, while the chords are steel. The chords are integrated in the timber-concrete composite floors.

The diagonals are connected with dowels and internal steel plates. The second floor cantilevers are 10 ft in the longitudinal direction and 13 ft in the transverse direction over the first floor.

The visible timber structure, as well as the glazed exterior and interior walls, create an intimate, open atmosphere.
