Due to subcontractor availability and programme Lyons O’Neill were asked by Willmott Dixon to progress this scheme as a Steel alternative despite it being conceived by the Client as an RC Structure. We developed alternatives which benefited from the flat slab approach of the concrete solution but benefited from the speed of the steel frames. By using a Westok Ultra Shallow Floor Beam system we were able to present a flat soffit whilst creating bespoke beams to work within the concept zoning. The fact that the beams are formed from individual Tee sections meant pre-cambering could easily be achieved allowing us to span the 8.5m spans with economic beam weights.
Due to the high level of fenestration within the elevations we opted for a portalised solution which gave a bracing free space.
