This architectural drawing is an Elevator Slab Formwork design with detail AutoCAD 2D drawing, dwg file, and CAD file. Elevator-slab construction, is the process of pouring concrete floor slabs on the ground, one on top of the other, and then lifting them into place on top of columns with hydraulic jacks. This approach, which is used for very tall multistory structures, gives significant formwork savings. For more details and information download the drawing file.
