Specifications include, but are not limited to: STEEL REINFORCEMENT: A. General: Comply with CRSI's "Manual of Standard Practice" for placing reinforcement.; 1. Do not cut or puncture vapor retarder. Repair damage and reseal vapor retarder before placing concrete.; B. Clean reinforcement of loose rust and mill scale, earth, ice, and other foreign materials that would reduce bond to concrete.; C. Accurately position, support, and secure reinforcement against displacement. Locate and support reinforcement with bar supports to maintain minimum concrete cover. Do not tack weld crossing reinforcing bars.; D. Set wire ties with ends directed into concrete, not toward exposed concrete surfaces.; E. Install welded wire reinforcement in longest practicable lengths on bar supports spaced to minimize sagging. Lap edges and ends of adjoining sheets at least one mesh spacing. Offset laps of adjoining sheet widths to prevent continuous laps in either direction. Lace overlaps with wire.; JOINTS: A. General: Construct joints true to line with faces perpendicular to surface plane of concrete.; B. Construction Joints: Install so strength and appearance of concrete are not impaired, at locations indicated or as approved by Architect. 1. Place joints perpendicular to main reinforcement. Continue reinforcement across construction joints unless otherwise indicated. Do not continue reinforcement through sides of strip placements of floors and slabs.; 2. Form keyed joints as indicated. Embed keys at least 1-1/2 inches into concrete.; 3. Locate horizontal joints in walls and columns at underside of floors, slabs, beams, and girders and at the top of footings or floor slabs.; 4. Space vertical joints in walls as indicated. Locate joints beside piers integral with walls, near corners, and in concealed locations where possible.; 5. Use a bonding agent at locations where fresh concrete is placed against hardened or partially hardened concrete surfaces.; LAYING MASONRY WALLS: A. Lay out walls in advance for accurate spacing of surface bond patterns with uniform joint thicknesses and for accurate location of openings, movement-type joints, returns, and offsets. Avoid using less-than-half-size units, particularly at corners, jambs, and, where possible, at other locations.; B. Bond Pattern for Exposed Masonry: Unless otherwise indicated, lay exposed masonry in running bond; do not use units with less than nominal 4-inch horizontal face dimensions at corners or jambs.; C. Lay concealed masonry with all units in a wythe in running bond or bonded by lapping not less than 4-inches. Bond and interlock each course of each wythe at corners. Do not use units with less than nominal 4-inch horizontal face dimensions at corners or jambs.; D. Stopping and Resuming Work: Stop work by racking back units in each course from those in course below; do not tooth. When resuming work, clean masonry surfaces that are to receive mortar before laying fresh masonry.; E. Built-in Work: As construction progresses, build in items specified in this and other Sections. Fill in solidly with masonry around built-in items.; COMPOSITE FLOOR DECK: Composite Floor Deck: Fabricate panels, with integrally embossed or raised pattern ribs and interlocking side laps, to comply with "SDI Specifications and Commentary for Composite Steel Floor Deck," in SDI Publication No. 31, with the minimum section properties indicated, and with the following: 1. Galvanized-Steel Sheet: ASTM A 653, Structural Steel (SS), Grade 33, G60 zinc coating.; 2. Profile Depth: 1-1/2 inches.; 3. Design Uncoated-Steel Thickness: as indicated.; 4. Span Condition: Double Span or more.
