PCI MNL-116, ACI 318, ACI 546R, ICRI 310.2R, ASTM C881, ASTM E488 (anchor pull-out)

• Visual inspection; systematic sounding; spall and crack mapping on elevation drawings.
• Anchor probe: expose representative anchors at minimum 3 per elevation; assess corrosion and capacity.
• GPR scan option: locate anchors without destructive probing; map cavity and panel thickness.

• Remove unsound concrete to ICRI CSP 6; clean rebar to SSPC-SP 6; apply corrosion inhibitor.
• Apply bonding agent; place cementitious repair mortar; match color and texture of adjacent precast.
• Apply elastomeric coating over repaired areas for uniform appearance and protection.

• Remove failed or corroded anchors; install new Type 316 SS anchor (epoxy-grouted).
• Anchor design by EOR; minimum 1" solid embedment in backup structure.
• Pull-out test per ASTM E488 on minimum 5% of new anchors; report to EOR.

Remove all existing sealants; install new backer rod; apply structural silicone or polyurethane sealant. Movement analysis required for large precast panels: confirm sealant movement capacity matches joint demand.

Source match from original precaster or approved substitute; submit mock-up for Owner approval. Erection per EOR-approved connection design; match panel finish and color to adjacent units.
