CCL provides voided slab system for £10m Higgs Centre

The Higgs Centre for Innovation is being constructed adjacent to Edinburgh's Royal Observatory

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.

Designed by JM architects and funded by the UK Government, the Higgs Centre is being constructed adjacent to Edinburgh’s Royal Observatory. It will be operated by the Science and Technology Facilities Council (STFC) in partnership with the University of Edinburgh

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.”
