The Wormsley Island Pavilion has been designed and constructed with refined precision and attention to detail, through close collaboration between the architect, fabricator and structural engineer. The bespoke stainless steel sections are legible throughout, as an honest expression of the structural framing of the building. Exposed connections were meticulously detailed to balance the structural and aesthetic requirements with those of constructibility. The architect demanded the highest quality finish to the steelwork, which was met by the fabricators who provided an almost sculptural level of finish to the structure.
The unusual challenge of delivering materials over a lake onto an island required thought to be given to the logistics of construction, and an early decision was made to prefabricate many elements of the structure. Driven steel piles were used as a cost-effective and practical foundation solution, linked by ground beams to form a stable base for the pavilion.
The footbridge consists of three spans, a total of 42m. The structure of each section consists of a single torsional tubular spine, from which cantilevers tapered I-beams supporting the 2.1m wide aluminium decking. To avoid penetrating the puddle clay lining of the lake, the footings sit on the bed with the bases sized to produce low bearing pressures. In order to minimise any long term settlement, the bases were pre-loaded with kentiledge in advance and the movements monitored.
