Concrete construction: Temporary support for cast in place (CIP) reinforced concrete structure for multi-story building in Los Angeles. This is a post-tensioned cast in place (CIP) reinforced concrete flat plate structural system. Flat plate because it is a slab supported by columns without girders, beams, or column capitols. Post-tensioned in that high-strength steel cables within the slab are highly tensioned after the concrete has gained its strength. The vertical shores under the upper slab, from which forms have been removed, are reshores to distribute the new floor's concrete construction loads to the floor(s) below. Therefore, as slab forms are dismantled, vertical shores are placed to help support the coming floors above. Reshores have been removed from the lower floor(s), as shown here, as floors were added above. The reshoring moves upward as the concrete structure moves upward.
