Concrete building construction: Formwork for next floor of concrete structure. Upper half of photo shows slab formwork for next concrete placement. Horizontal steel beams support wood joists, which support plywood sheathing, which will support new concrete floor slab. Vertical pipe and frame shores support beams. The pipe and frame shores will carry new concrete load to the slab whose underside is in lower half of photo. Steel cross bracing provides support against lateral/horizontal loads. The pipe frame shores in lower portion will help distribute some of the new concrete slab weight to the slab(s) below what is shown. Epoxy coated (green) reinforcing steel will tie new concrete structure to the concrete structure shown. Science Instruction Center Building, University of Michigan, Ann Arbor, 2002.
