Built were contracted to complete the transformation project of 25 Martin Place, in Sydney's CBD - previously known as MLC Centre. As part of the sequence of works, they required access to waterproof a large cylindrical substation vent, attached to the side of the building.
The challenge was that these works were required to be done after the building hoarding and scaffold was removed. The only access was off the roof. Although complex, this would typically be done utilising steel scaffolding. However after review, it became evident that a much more lightweight system was required, than what is achievable with any steel system. Enter Proscaf aluminium.
Express Scaffolding, in conjunction with EA Associates Engineering, was able to propose an extremely efficient design that was approximately 60% lighter in weight than any other solution proposed. This was achieved through application of the Proscaf Aluminium technical data in design, with the high bearing capacities of key components such as ledgers, standard, braces and specialist Proscaf system fittings vital to the integrity of the scaffold.
The result was drop scaffold, that cantilevered out over 5m and then dropped down 4m, to wrap and provide access around the full diameter of the vent. Push ties back into the building helped maintain stability of the scaffold.
The client was extremely happy with the access provided, and the fact that Express was able to produce an efficient, safe, and practical solution at short notice.
