Concrete construction: Formwork and other 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. What looks somewhat like wall formwork around part of the exterior is a sheathed fall protection guard rail. Column forms are the vertical wood rectangular forms, with steel outside horizontal, spaced support brackets. These forms surround the column steel reinforcing, erected as steel cages, some of which have not yet had forms erected around them. The slab formwork is plyform sheathing to support the concrete, metal horizontal joists to support the sheathing, galvanized steel shoring trusses, with screw jacks at base, spaced to support joists. The vertical shores under the lower 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. Wilshire Blvd, Westwood, Los Angeles, CA, 2004.
