Working on top of ARUP?s structural steel frame, AR-MA worked with ARC Roofing to design, fabricate, assemble, and install, the roof modules, finished with flat-lock zinc panel, within exceptionally tight tolerances. To ensure the required accuracy, AR-MA developed and maintained a full, virtual-design-and-construction, parametric model throughout the project. Following confirmation of the design, this model was then employed within a file-to-factory pipeline to produce all required zinc and sub-structural steel components. These were then assembled in ARC Roofing?s factory and sent to site for installation.
On site, the modules were crane-lowered into custom frames formed with mitred steel angles, fitted to the roof?s guttering (also designed by AR-MA) prior to module installation. Less than a millimetre accuracy was maintained throughout ...
