The package consisted of three main elements, being the Lateral Walkways each approx 197 linear metres to each side of the building, the Radial Access Walkways following the roof line at each gable end of the building, and Parapet Handrails at the main roof eaves, again running the length of the building and resin fixed through existing stone copers - all polyester powder coated finish. All details closely copied the original ‘Barlow’ design, the lateral walkways being mounted on cast aluminium brackets incorporating various tolerance to combat roof movement from its’ initial build. All walkways were fitted with a proprietary tested & commissioned ‘Mansafe’ system. The walkway infills and stair treads were galvanised open steel flooring and the balustrades designed to suit a horizontal loading of 0.36kN/lin.m. The walkway posts were spaced to suit the main roof trusses and incorporated clamped handrail and fabricated balustrade panels housing ornamental feature castings replicated from the original design, this requiring further weld testing and certification for dissimilar metals. At the north end and to each side are the main access towers to the roof where walkway platforms were built around the towers and included a retractable extending walkway with lockable gates extending over the end of the building to access the maintenance gantry over the new transition roof.
