A maximum of 10 minutes before new concrete is placed, all construction joints shall be wetted and standing water removed. Construction joints shall be located as shown on the drawings or shall be approved by the Contractor. Construction joints in floors shall be located within the middle third of spans of slabs, beams, and girders. Construction joints in girders shall be offset a minimum distance of two times the width of intersecting beams. Beams, girders, or slabs supported by columns or walls shall not be cast or erected until concrete in the vertical support members is no longer plastic. Beams, girders, haunches, drop panels, and capitals shall be placed monolithically as part of a slab system, unless otherwise shown in design drawings or specifications. Contraction Joints While the concrete is still plastic (i.e., within several hours after placement), provide joints in slabs at no more than 10 feet on center in each direction or as shown on the drawings. The depth of each joint will be at least one-quarter of the slab thickness, but not less than one inch. DETAILS OF REINFORCEMENT Standard hooks The term “standard hook,” as used in this document, shall mean one of the following: A 180-degree bend plus 4db extension, but not less than 2-1/2 in. at free end of bar. A 90-degree bend plus 12db extension at free end of bar. For stirrup and tie hooks No. 5 bar and smaller, 90-degree bend plus 6db extension at free end of bar; or No. 6, No. 7, and No. 8 bar, 90-degree bend plus 12db extension at free end of bar; or No. 8 bar and smaller, 135-degree bend plus 6db extension at free end of bar. Seismic hooks defined as follows: a hook on a stirrup, hoop, or crosstie having a bend not less than 135 degrees, except that circular hoops shall have a bend not less than 90 degrees. Hooks shall have a six-diameter (but not less than 3 in.) extension that
