Hardy Services were asked to provide a fully enclosed and weather proof, access scaffold to the full external façade of the 15th-century mill. This structure was also to incorporate full boarded access and a modular temporary roof system, providing full weather protection to safeguard the delicate restoration works being carried out on the building within.
The scaffold was erected to facilitate a working platform at eaves level to enable the roof works to be completed. The mill roof is of such a size and pitch that saddled access platforms where to be erected at both removal and re-instatement stages of the roof works, providing a safe point of access for the roofers. Further to the roof repairs localised pointing and general masonry repairs were also to be considered.
The age and nature of the mill was to provide its own unique problems with a view to tying the scaffold structure, as no physical fixings could be utilised with in the building fabric, an essential component when erecting such a structure. To alleviate this problem, ground anchors and additional bracing were introduced in a way as to minimise the disruption to the trades using the scaffold, but still provide the structural rigidity and ballast needed to prevent the large roof structure from failing.
Internal to the mill, a full boarded protective platform was to be constructed to provide a fall protection, during the progression of the roof works. This was also to be utilised by following trades completing mill right works, joinery and timber repairs etc. This was completed via the use of various beams and cantilevered sections to successfully navigate the awkward internal space of the mill.
The entire structure was encased at the base by means of a 5m high galvanised steel sheet hoarding for security and to meet the insurance criteria.
