S7
Location: Mýrdal, Iceland
Project Name: S7
A shopping Center and Café — a unique public project in which all load-bearing structures were made entirely of glued laminated timber and timber-frame wall panels. The building was designed using Prefab technology, which allowed the main structural elements to be prefabricated in the factory, transported by sea, and quickly assembled on-site.
A distinctive feature is its remarkable architecture, including an original wave-shaped main roof. The project successfully used Trimble Connect for coordination and was completed in the shortest possible time. Enhanced fire safety and sound insulation requirements were met using concealed connections for glulam elements and sealing all holes with wooden plugs and strips.
Main Part Design OÜ was responsible for:
- Structural calculations and reports
- Project coordination
- Development of the structural BIM model – LOD400 and GA drawings
- Production of detailed construction and manufacturing documentation
- Including CNC files in BVN/BVX format for Hundegger cutting machines
Structural Overview
The upper part of the building features a frame–braced system with glued laminated timber frames along axes 2–5. Rigid joints are used between columns, foundations, and roof beams. Vertical bracings are provided along the external axes G–H–6, G–1–2, and F–3–4, complemented by wall panels with OSB and plywood sheathing acting as vertical diaphragms. Roof stability is ensured by diagonal glulam braces and horizontal steel tube bracings.
The lower part of the building is composed of framed wall panels. Its roof structure consists of a load-bearing steel beam grid with profiled steel sheeting acting as a horizontal diaphragm.
