The system is often referred to as profiled steel floor decking. The permanent formwork remains in situ for the life of the building and supports the poured concrete. Considerable efficiencies may be achieved on large multi-storey buildings. The construction process enables ‘follow-on trades' to work on lower floor levels beneath the live construction decks as it creates unimpeded access because the need for temporary propping and retro-shores is eliminated. Contributing to the construction speed, the profiled floor deck creates a working platform (eliminating scaffolding) and also reduces concrete volumes which minimises the overall building dead weight and consequently lowers costs of columns and foundations. Other benefits include high fire resistance, good sound insulation and the ability to incorporate the formwork into composite (concrete) beams.
