Key provisions of the revised steel erection standard include:

Site Layout and Construction Sequence

• Requires certification of proper curing of concrete in footings, piers, etc. for steel columns.
  
  
• Requires controlling contractor to provide erector with a safe site layout including pre-planning routes for hoisting loads.

• Requires pre-planning of key erection elements, including coordination with controlling contractor before erection begins, in certain circumstances.

• Provides additional crane safety for steel erection.
  
  
• Minimizes employee exposure to overhead loads through pre-planning and work practice requirements.
  
  
• Prescribes proper procedure for multiple lifts (christmas-treeing).

• Provides safer walking/working surfaces by eliminating tripping hazards and minimizes slips through new slip resistance requirements.
  
  
• Provides specific work practices regarding safely landing deck bundles and promoting the prompt protection from fall hazards in interior openings.

• Requires 4 anchor bolts per column along with other column stability requirements.
  
  
• Requires procedures for adequacy of anchor bolts that have been modified in the field.

• Eliminates extremely dangerous collapse hazards associated with making double connections at columns.

• Requirements minimizing collapse of lightweight steel joists by addressing need for erection bridging and method of attachment.
  
  
• Requirements for bridging terminus anchors with illustrations and drawings in a non-mandatory appendix (provided by SJI).
  
  
• New requirements to minimize collapse in placing loads on steel joists.

• Requirements to minimize collapse in the erection of these specialized structures which account for a major portion of steel erection in this country.

• Performance provisions that address hazards of falling objects in steel erection.

• Controlled decking zone (CDZ) provisions to prevent decking fatalities.
  
  
• Deckers in a CDZ and connectors must be protected at heights greater than two stories or 30 feet. Connectors between 15 and 30 feet must wear fall arrest or restraint equipment and be able to be tied off or be provided another means of fall protection.
  
  
• Requires fall protection for all others engaged in steel erection at heights greater than 15 feet.

• Requires qualified person to train exposed workers in fall protection.
  
  
• Requires qualified person to train exposed workers engaged in special, high risk activities
