Crane & rigging operations are highly regulated by OSHA, and safety begins long before any equipment arrives on-site. Contracts have been negotiated and signed. Equipment has been certified prior to transport. Certified operators and signal persons have been hired. Safety is a tremendous responsibility, and has been delegated to the General Contractor or Superintendent. Safety Programs are reviewed, and Safety Plans are coordinated among subcontractors. Site Specific Safety Plans are developed and approved, and Crane Safety Plans (including specific Lift Plans) are developed to address crane safety at each step of the job. Our crane and rigging customers have the most detailed safety plans we encounter. Safety is a critical concern at every level, and requires the involvement of architects and engineers.
As with any construction project, site safety defines access and security of a site and equipment security. Due to their size, crane and rigging operations pose special considerations for protecting adjacent properties. Site terrain, securement of equipment, weather assessment, weight and load parameters, arrangement and inspection of rigging equipment all impact a safe lift.
Transportation, erection, and dismantling of cranes present their own concerns. High axle loads and positioning of equipment can create high ground pressures impacting stability. Professional engineers are required to assess the impact of numerous factors on equipment to assure safety during each stage of crane erection, dismantling, and transport.
Safety is an obvious priority in this highly regulated and high risk industry, and requires detailed documentation compliance. Safety programs and plans should be readily accessible on-site. A safety coordinator should be designated to maintain all documentation. A safety trailer should be established and should contain first aid and extra PPE. Communication between the GC, contractors, managers, supervisors, workers, and vendors is critical. Clear lines of responsibility must be drawn, and coordination of all parties is essential to project safety. Safe, professional management of the job site substantially reduces the risk of catastrophic incident.
