time for the reinforcing cages. BauGrid reinforcement grids, manu- factured from engineer-approved shop drawings, remove the need for fabrication and site supervision of the tie assembly by arriving on site or in the yard as a custom-fabricated, dimensionally accurate, single- piece grid. By eliminating the lengthy end hooks, these grids weigh less than their conventional tie assembly counterparts and provide a uniform product that can be quickly assembled with the longitudinal steel to form rigid and stable cages. The improved rigidity and reduced weight of the grids allow for easier handling, thereby reducing crane and labor time for installation, further reducing costs by speeding up the construction. The consistency and accuracy of the rigid cages pro - vide a perfect facade for rapid formwork installation. The reduced cage congestion increases the speed of concrete placement, facilitates the vibration process, and improves concrete consolidation. "There is no better way to build reinforced rebar cages for high rise structures than with BauGrid Reinforcement. The system helped us reduce rebar congestion significantly and made the construction of our largest columns possible. The system facilitated accurate and efficient application of self-climbing forms for the most congested area at the bottom 6 floors. The consistency and precision of longitudinal rebar placement using BauGrid significantly improved form climbing and concrete placement." -Mr. Kamal Kang, Senior Construction Manager, Samsung C& T Construction, South Korea.
