SICC-703.2 Particular Elements.

a. Concrete formwork. The SIER shall verify that the formwork materials, cleanliness, size, and installation conform to approved formwork fabrication and erection documents, prior to placement of concrete.

b. Reinforcing steel. The SIER shall verify that reinforcing steel is in compliance with County approved construction documents and SER approved fabrication and erection documents, including welding of reinforcement of the structural seismic-force-resisting system.

c. Tendons to be post-tensioned. The SIER shall verify that tendons to be post-tensioned are in compliance with County approved construction documents and SER approved fabrication and erection documents, including full-time monitoring of grouting, consolidation and reconsolidation of bonded
