CCL, the specialist in engineered solutions for structures, has provided a voided slab system for the £10million space technology Higgs Centre for Innovation in Edinburgh following a value engineering exercise to reduce concrete volumes on the scheme.
The original design for the level two slab was for a conventional 400mm reinforced solid concrete slab. A value engineering exercise to reduce concrete consumption and the building’s environmental impact along with the structural loading of the slab led to the change of specification to a voided slab, using a voiding system supplied by CCL.
Toby Hemsley from the project’s reinforced concrete frame contractor, Stephenson Group says: “By changing the specification, we were able to reduce the volume of concrete used by 30%, which also reduced the slab’s weight by 30% but retained 90% of its original stiffness. The result is a slab of the same profile and structural integrity delivered more cost-effectively and with reduced amounts of concrete.”
CCL supplied 1,844 re-cycled synthetic modules, which were laid between the steel rebar reinforcement prior to the concrete pour, thereby creating the voids.
Matt Gilliver, technical director of CCL GB adds: “Our voided slab system has been used successfully throughout the world to reduce concrete consumption, costs and structural loading, while providing a robust solution.”
