Pre-Construction Planning Successful placement begins before bars arrive on site. Review of contract drawings, bar-bending schedules, and shop drawings is essential to coordinate bar sizes, shapes, and counts.

Fabricated cages and mats are often used to expedite placement and reduce errors. Ordering and staging of rebar, placing equipment, and temporary bracing should be planned to minimize handling and repositioning.
