Trends in the Ironworker (Reinforcing) trade
Technology
The use of electronic devices such as tablets and laptops are now commonly used on-site for reviewing and marking up site documentation (e.g., prints, change orders).
Ironworkers (reinforcing) use digital technologies and software in structural design and fabrication. These enable ironworkers to access 3D models, simulations, and animations of ironwork structures and components created by detailers and designers. Digital technologies and software can help ironworkers (reinforcing) to visualize, plan, and optimize their work. They can also facilitate the communication and collaboration among ironworkers, engineers, architects and clients. Ironworkers (reinforcing) also use virtual and augmented reality tools for training purposes such as mobile equipment training.
Ironworkers (reinforcing) may use drones and cameras to inspect and monitor ironwork projects. Drones and cameras can provide aerial views and high-resolution images of ironwork structures and components. Ironworkers may use wearable technology, RFID, and QR codes for tracing materials and monitoring the health and safety of workers. Digital technologies and software can help ironworkers (reinforcing) to identify defects, damages, or misalignments that may not be visible from the ground. They can also improve the safety and efficiency of ironwork operations by reducing the need for manual inspections and scaffolding.
Health and Safety
Ironworkers (reinforcing) and their employers are increasingly being supported in addressing and promoting mental health and well-being. Substance abuse programs are becoming more accepted and available in the trade.
There are improvements in personal protective equipment (PPE) and clothing for ironworkers (reinforcing) that can protect them from lacerations, respiratory hazards such as toxic fumes and respiratory particulates, noise, heat, cold, radiation and burns.
There is a greater emphasis on process and documentation of work to prevent and monitor workplace injuries and overexertion, as well as to support recovery. Safety performance is extremely important for a contractor’s ability to bid on projects.
Tools and Equipment
There are more advanced hoisting and rigging tools and equipment such as self-propelled modular transporters (SPMTs). These tools and equipment are used by ironworkers to move materials and equipment.
There is a greater variety of mobile equipment used by ironworkers such as rough terrain forklifts and mobile elevating work platforms.
There are more computerized and automated machines used in fabrication and installation of components such as robotic tying machines and tying guns.
Improvements in rope access equipment is emerging to replace the use of scaffolding. This is used to access challenging locations for tasks such as inspection and installation.
Products/Materials
New materials and products are being developed and improved. Products such as insulated concrete form (ICF), helical screw piles and composite materials such as timber-concrete-hybrid panels and glass-fiber reinforced polymers (GFRP) have become more prevalent. Also, it is a trend to use larger mass timber structural components such as cross-laminated timber (CLT) and glulam (GLT) in addition to steel or concrete.
Ironworkers (reinforcing) may also need to work with specialty rebar, as well as precast and pretensioned concrete.
Some specialized construction materials for the small modular reactor nuclear sector includes steel-brick modular wall systems, which are installed by ironworkers.
The design of structures exposed to seismic and cyclic loading is constantly evolving and ironworkers (reinforcing) are continuously adapting to new construction methodology. These new designs have introduced changes for bolted and welded connections as well as reinforced concrete in structures.
Environmental
Ironworkers (reinforcing) are involved in various environmental advances in their trade. They work with recycled steel and other products that can save resources and reduce emissions compared to new materials.
They participate in green building projects that can improve the energy efficiency and sustainability of buildings and structures. Green building practices can include using renewable energy sources, minimizing waste, enhancing indoor environmental quality, and reducing the environmental footprint of construction.
Ironworkers (reinforcing) can work on renewable energy generation and green building projects such as hydroelectric facilities, battery and electric vehicle assembly plants, solar arrays, wind turbines, green roofs, hydrogen plants and other eco-friendly features.
Legislative and Regulatory
Ironworkers (reinforcing) need to stay up-to-date on building code changes. The introduction and emphasis of energy efficiency code requirements has impacted trade practices including more traceability and accountability for materials and processes for building construction.
Safety regulations and legislation in each jurisdiction are also subject to frequent updates and changes.
Other
Depending on jurisdictional regulations, standards and limitations, welding is an important skill for many ironworkers (reinforcing), as they need to form structures and components from metal pieces. Ironworkers (reinforcing) use new welding techniques and equipment to join metal pieces together. New welding techniques and equipment can improve the quality and durability of structural products.
As new rigging technology emerges, ironworkers (reinforcing) will be required to stay abreast of current and future trends to facilitate the hoisting and maneuvering of construction materials, components, and machinery safely and efficiently while following local and national safety standards and regulations.
