Reinforcement, Embeds, and Inserts
The panel is a lifting and connection system
Reinforcement follows the placing drawings: bar size, spacing, cover, lap lengths, and the added steel around openings, corners, and lift inserts. Chairs and bar supports hold the steel at the correct depth - the cover on the face that becomes the exterior is a durability requirement, not a preference.
Embeds and inserts are the parts that fail loudly. Lift inserts must match the rigging, must sit at the location shown, and must be plugged or capped so concrete cannot enter threads or voids. Brace inserts, weld plates, bearing angles, column anchors, electrical boxes, and conduit all need to be located, leveled, and tied off so they cannot move during placement. Verify every embed against the panel elevation before the pour and again after vibration.
Traps
- Letting a vibrator strike inserts or rebar and displace them.
- Using an insert at an embedment depth or orientation that does not match the manufacturer's published capacity.
- Forgetting to remove temporary plugs, or leaving tape and foam inside coil inserts.
- Accepting an insert because it "looks straight" without checking plan location and elevation.
Rule of thumb
Position lift inserts so the lifting axis stays within the middle third of the panel width, and keep any insert at least 1½ times its embedment depth from a free edge unless the engineer directs otherwise.
