This structural plan details the installation of galvanised steelwork at Chiswick Business Park, designed to support a Millboard composite decking system. The layout features a network of 127 x 76 UB and 152 x 89 UB beams, secondary support members, and edge framing installed atop existing concrete plinths. The drawing outlines joist spans, support conditions, trimming areas, and required alignment with Duospan 51mm joists at 300mm centers. This precision steelwork—fabricated and installed by Steelo—formed the backbone of the decking system, ensuring long-term durability and structural integrity in a commercial landscape setting.
