An access and protection deck was designed at Victoria Coach Station to facilitate maintenance work on the deluge system within the roof structure. The deck was suspended from the existing steel roof trusses. A structural assessment revealed that the bottom chord of the trusses required reinforcement for the duration of the project. To minimise the impact on the structure, standard scaffold components were used. Scaffold tubes were connected between existing node points on the trusses to increase the tension capacity of the bottom chord.
Spine beams were positioned perpendicular to the roof trusses, secured by box ties. Additional beams were placed parallel to the trusses at 2.1m C/C, forming the lower working platform. This platform supported a stepped birdcage scaffold, which provided access to the apex of the roof. To reduce the dead load, aluminium tubes were used throughout the scaffold design. Notably, the coach station remained fully operational throughout the project.
