Common Problems and Remedies Typical issues include inadequate cover due to crushed or displaced chairs, congested reinforcement hindering concrete consolidation, mislocated bars from poor layout, and damaged bar coatings. Remedies involve using larger or more frequent supports, prefabricating cages, revising bar layouts in collaboration with designers, and instituting stricter inspection controls.
Before a single yard of concrete is poured, the "iron" must stay put. This is the job of . The CRSI Placing Reinforcing Bars manual categorizes these extensively. Crsi Placing Reinforcing Bars.pdf
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. CRSI emphasizes clear communication among designers, fabricators, and placing crews to address congested areas, embedment of accessories (dowels, anchors, inserts), and sequence of pours. 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. This is the job of
