FABRICATION AESS 1 Use special care in handling and shipping of AESS both before and after shop minimize damage to any shop finish. Use Nylon type slings or softeners when using chains or wire rope slings. The permissible tolerances for member depth, width, out of square, and camber and sweep shall be as specified in ASTM A6/A6M-2014 Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling (ASTM A6/A6M), ASTM A500/A500M-2013 Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes (ASTM A500/A500M), and Standard Specification for Cold-Formed Welded Carbon Steel Structural Sections (HSS) (ASTM A1085/A1085M). Fabricate and assemble AESS in the shop to the greatest extent possible. Locate field joints in AESS assemblies at concealed locations or as approved by the Architect. Detail AESS assemblies to minimize field handling and expedite erection. Remove blemishes or unsightly surfaces resulting from temporary braces or fixtures. Remove all backing and run out tabs. Grind all sharp edges smooth, including all sheared, punched or flame cut edges Provide a continuous appearance to all welded joints including tack welds. Provide joint filler at intermittent welds. Bolted Connections: Make in accordance with Section 05 12 00. Provide bolt type and finish as noted herein. Weld Connections: Comply with AWS D1.1 and Section 05 12 00. Appearance and quality of welds shall be consistent. Assemble and weld built-up sections by methods that will maintain alignment of members without warp exceeding the tolerance of this section. Install all bolts on the same side of the connection. Oriented uniformly in the direction indicated Consistent from one connection to another. Remove all weld spatter, slivers and similar surface discontinuities.
