Key Responsibilities Framework Assembly Erect steel components (columns, beams, braces) using bolts, rivets, or welds. Align structures to precise tolerances (e.g., 3mm deviation). Blueprint Interpretation Read and implement engineering drawings (GA, detail, and connection drawings). Verify dimensions and positions via laser levels, plumb bobs, and total stations. Crane Operations Signal crane operators (CPCS A40) during lifts using BS 7121 hand signals. Secure loads with slings/chains and ensure weight limits are respected. Welding/Bolting Perform on-site welding (if coded) to BS EN ISO 3834 standards. Torque bolts to specified tensions (e.g., HRC bolts to 300 Nm). Safety and Compliance Follow Work at Height Regulations 2005 (harnesses, scaffolding, MEWPs). Conduct toolbox talks and risk assessments for tasks like connector decking. Adhere to CDM 2015 and site-specific rules (e.g., exclusion zones).
