28.B.04 Written notifications. Before authorizing the commencement of steel erection, the Controlling contractor must ensure that the steel erector is provided with the following written notifications:

  1. The concrete in the footings, piers, and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75% of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.
  2. Any repairs, replacements, and modifications to the anchor bolts were conducted in accordance with contract specifications and/or project structural engineer of record.
  3. A steel erection contractor must not erect steel unless it has received written notification that the concrete in the footings, piers and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75% of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.
  4. Both steel and concrete contractors will keep a copy of this written notification on-site.

  2. An adequately compacted, properly graded, drained area readily accessible to the work with adequate space for the safe storage of materials and the safe operation of the erector's equipment.
  3. Pre-planning of overhead hoisting operations. All hoisting operations in steel erection must be pre-planned.

28.B.06 Load Handling Equipment (LHE) and rigging. All applicable requirements of Sections 15 and 16 apply to this Section.

28.B.07 Inspection of LHE (cranes, hoists, etc). A CP must visually inspect LHE being used in steel erection activities prior to each shift as per Section 16.D.
