Timber decking was being installed onto a flat roof on a building opposite the Olympic Park in Stratford, East London.
In order to match another section of timber decking, the clearance from the roof-deck was fairly substantial. The TD Extra pedestals, with extended stem heights of up to 380mm, were selected to give the contractors the scope and flexibility they needed across the entire roof area.
A framework of treated softwood timber joists was constructed, with the timbers being fixed through the sidebars of the TD Mobile heads in order to create a sturdy base structure. The pedestals were not fixed through the membrane as this would compromise the seal.
The pedestals remained freestanding with the decking fixed to the joists to create the walking surface.
