Fjerdingby School is a primary school in Rælingen comprising teaching facilities, a resource department and an integrated multi-purpose hall. The project is characterised by the use of prefabricated structural systems supported by a reinforced concrete substructure.
The complex is divided into three main structural blocks. Horizontal stability is ensured through a combination of reinforced concrete cores, load-bearing concrete walls and steel bracing systems. The floor structures consist of hollow-core slabs acting as diaphragms for the transfer of horizontal loads to the stabilising elements.
The building is partially embedded into the terrain, with foundations bearing directly on rock and connected by a continuous slab on grade. Uplift forces are resisted by post-tensioned tendons anchored into the rock bed, while expansion joints allow for movements and limit seismic effects.
The reinforced concrete foundations were analysed using three-dimensional finite element models for both construction and final stages.
The project is designed as a nearly zero emission building (nZEB) and is BREEAM certified. Fjerdingby School is also the first school project in Norway to be delivered using the Best Value Procurement (BVP) model.
Degree of Freedom acted as structural engineer, contributing to the design of the load-bearing structural system throughout the project.
