Perform qualification test at the worksite and notify the Contracting Officer 24 hours prior to conducting tests. Special welding procedures and welders qualified by others may be accepted as permitted by AWS D1.4/D1.4M. Submit a list of qualified welders names. 1.4 DELIVERY, STORAGE, AND HANDLING Store reinforcement and accessories off the ground on platforms, skids, or other supports. PART 2 PRODUCTS 2.1 DOWELS Provide dowels conforming to ASTM A675/A675M, Grade 80 or ASTM A1035/A1035M. Steel pipe conforming to ASTM A53/A53M, Schedule 80, may be used as dowels provided the ends are closed with metal or plastic inserts or with mortar.[ Provide plate dowels conforming to ASTM A36/A36M, of size and spacing indicated. Plate dowel system must minimize shrinkage restraint by [using a tapered shape] [or] [formed void] [or] [by having compressible material on the vertical faces with a thin bond breaker on the top and bottom dowel surfaces.]] 2.2 FABRICATED BAR MATS Fabricated bar mats conforming to ASTM A184/A184M. 2.3 REINFORCING STEEL Reinforcing steel of deformed bars conforming to ASTM A615/A615M, ASTM A706/A706M, or ASTM A1035/A1035M grades and sizes as indicated. Cold drawn wire used for spiral reinforcement must conform to ASTM A1064/A1064M. Submit certified copies of mill reports attesting that the reinforcing steel furnished contains no less than 25 percent recycled scrap steel and meets the requirements specified herein, prior to the installation of reinforcing steel. 2.4 WELDED WIRE REINFORCING Welded wire reinforcing conforming to ASTM A1064/A1064M. When directed by the Contracting Officer for special applications, use welded wire reinforcing conforming to ASTM A884/A884M. For wire with a specified yield strength (fy) exceeding 400 MPa 60,000 psi, fy must be the stress corresponding to a strain of 0.35 percent. 2.5 WIRE TIES Use wire ties that are 16 gauge or heavier black annealed steel wire.[ Ties for epoxy-coated bars mustl be vinyl-coated or epoxy-coated.][ Use zinc-coated ties for zinc-coated bars.] -- 3 of 90 -- Jefferson Barracks - Covered Parking 1218003 Section 03 20 00.00 Page 4 PART 3 EXECUTION 3.1 REINFORCEMENT Fabricate and place reinforcement steel and accessories as specified, as indicated, and as shown on approved shop drawings. Fabrication and placement details of steel and accessories not specified or shown mustl be in accordance with ACI SP-66 and ACI 318M ACI 318. Cold bend reinforcement unless otherwise authorized. Bending may be accomplished in the field or at the mill.[ Mill bend zinc-coated and epoxy-coated bars prior to coating. Bend all steel cold unless authorized.] Do not bend bars after embedment in concrete. Place safety caps on all exposed ends of vertical concrete reinforcement bars that…
