Key Responsibilities and Required Skills for Ironworker (Structural & Reinforcing)

🎯 Role Definition

An Ironworker installs, fabricates, erects, and secures structural steel, metal components, and reinforcing bar (rebar) for buildings, bridges, industrial plants, and other heavy construction projects. This role blends hands-on fabrication and welding with rigging and lifting, blueprint interpretation, and strict adherence to safety and quality standards. Ironworkers work in shop and field environments, often at heights, and coordinate closely with crane operators, foremen, engineers, and other trades to deliver safe, on-time installations that meet structural and code requirements.

Core Responsibilities

Primary Functions

Read, interpret, and apply structural drawings, blueprints, fabrication shop drawings, and project specifications to plan and execute the installation, alignment, and anchoring of steel columns, beams, joists, trusses, and stairs while ensuring dimensional accuracy and code compliance.
Erect and align structural steel components using cranes, hoists, winches, slings, and tag lines, coordinating closely with crane operators and rigging teams to perform safe, complex lifts and manage load dynamics during placement.
Perform precise field layout, mark-off, and fit-up of steel components; measure and transfer dimensions, set elevations, and verify alignment using levels, laser tools, plumb bobs, and tape measures before bolting or welding.
Install and tie reinforcing steel (rebar) to specified spacing and configurations for concrete slabs, walls, beams, and footings; set chairs, spacers, embed plates, and dowels per engineered drawings.
Bolt, torque, and tension structural connections to specified torque values using impact wrenches, hydraulic torque tools, and calibrated hand tools; perform quality checks on bolted assemblies.
Execute high-quality welding (SMAW, FCAW/MIG, GMAW, GTAW/TIG as required) and thermal cutting (oxy-fuel, plasma) to join or modify steel members, ensuring welds meet AWS codes and project-specific welding procedures.
Fit, grind, bevel, and prepare metal surfaces for welding and connection; perform tack welding, final welds, and post-weld inspections to meet quality and dimensional tolerances.
Install metal decking, stair systems, handrails, grating, and miscellaneous metalwork; fasten decking and accessories and prepare for concrete placement or final finishes.
Participate in pre-job planning, review lift plans, and conduct job hazard analyses (JHAs); implement fall protection systems, anchor points, and perimeter protection to meet OSHA and site safety requirements.
Apply rigging knowledge to select appropriate slings, shackles, and hardware; inspect rigging equipment daily, tag out defective gear, and maintain rigging logs to ensure safe lifting operations.
Erect temporary bracing, shoring, and falsework in coordination with structural engineers to stabilize members during erection and until permanent connections are secure.
Perform demolition and dismantling of existing steel structures safely using cutting and rigging techniques while protecting site personnel and surrounding property.
Use hand and power tools, grinders, impact drivers, beams clamps, and precision tools safely and maintain them in good working order; report and assist with repairs or replacements when required.
Conduct visual inspections and assist with non-destructive testing (NDT) coordination (e.g., magnetic particle, ultrasonic) as required by project QA/QC plans; document and report defects or non-conforming work.
Maintain accurate daily logs, timecards, material consumption reports, and as-built records; communicate progress and issues to foremen and project managers promptly.
Coordinate with fabricators, detailers, and shop personnel to resolve fit-up and dimensional discrepancies between shop-fabricated members and field conditions; perform field modifications as necessary.
Install anchor bolts, sleeves, and embeds for connection to concrete foundations and set anchor templates to tolerance during concrete pours and formwork removal.
Ensure proper handling, storage, and inventory control of structural steel, rebar, and materials on site; protect steel from damage and corrosion prior to installation (covering, painting, or priming as required).
Mentor, train, and supervise apprentices and new crew members in safe work practices, proper rigging, welding techniques, and blueprint reading to develop a competent field team.
Participate in daily toolbox talks, safety meetings, and project-specific training; demonstrate a continuous safety-first mindset and enforce site rules among crew members.
Collaborate with other trades (concrete, carpentry, mechanical, electrical) and the general contractor to coordinate sequencing, access, and interfaces to avoid rework and schedule delays.
Perform site cleanup, debris removal, and housekeeping duties to maintain safe walkways, access points, and a professional work environment.
Comply with environmental and waste disposal requirements for cutting fluids, solvents, and metal waste; report spills and assist with corrective measures.

Secondary Functions

Assist project management with material takeoffs and provide field feedback on material usage and waste reduction opportunities.
Support procurement teams by verifying delivered materials against purchase orders and reporting shortages or damage.
Participate in mock-ups, pre-installation inspections, and client walkthroughs to confirm quality and finish expectations.
Contribute to continuous improvement by suggesting safer, faster erection methods and more efficient rigging plans based on field experience.
Help maintain and inspect powered access equipment (scissor lifts, boom lifts, forklifts) and report maintenance needs.
Document day-to-day field variations and communicate as-built changes to the drafting/detailing team for redlines.
Assist in pre-fabrication and shop tasks when required to accelerate schedules or remediate fit issues.
Support commissioning and turnover activities by verifying installed components match design intent and record locations of embedded items.
Provide input to schedule updates and labor forecasts based on crew productivity and site conditions.
Participate in client and subcontractor coordination meetings to align on milestones, deliveries, and safety expectations.
