Fabrication & Erections

Most of the work needed to produce a steel structure for a building is undertaken offsite in the steelwork contractor’s fabrication factory. There the steel sections and plates from the rolling mills are cut, drilled and welded to make the steel components that are then delivered to the project site. The fabrication process is controlled using a computer model of the structure that generates electronic data

for automatic machines and detailed fabrication drawings for assembly and welding. At the site the steelwork contractor uses cranes and access equipment to undertake the erection of these fabricated beams, columns, bracings etc. The structure has to be plumbed, lined and levelled to meet the specification before the frame is ready for handover to the general contractor
