NOTES PIPE RAILING & POSTS: Structural Tube, Pipe and Bar shall be in accordance with ASTM B22 or ASTM B429, Alloy 606-T6. End Rail 90 bends and corner bends with maximum 4-0" post spacing, may be Alloy 606-T6. s and End Rails shall be fabricated and installed plumb, " tolerance when measured at above the foundation. Corners and changes in tangential longitudinal alignment, may be made continuous with a bend radius or terminated at adjoining sections with a standard end hoop when handrails are not required. For changes in tangential longitudinal alignment greater than 45, posts shall be positioned at a maximum distance of 2-0" each side of the corner and shall not be located at the corner apex. For curved longitudinal alignments the top and bottom rails and handrails shall be shop bent to match the alignment radius.

SHIM PLATES: Shim Plates shall be aluminum in accordance with ASTM B209, Alloy 606 or 606. Shim plates shall be used for foundation height adjustments greater than 4" and localized irregularities greater than 8". Field trim shim plates when necessary to match the contours of the foundation. Bevelled shim plates may be used in lieu of trimmed flat shim plates shown. Stacked shim plates must be bonded together with adhesive bonding material and limited to a maximum total thickness of longer anchor bolts are provided for the exposed thread length. COATINGS: The aluminum railing shall be mill finish unless otherwise noted in the Contract Documents. All nuts, bolts and washers shall be hot-dip galvanized in accordance with Section 962 of the Specifications. ANCHOR BOLTS: Anchor bolts shall be in accordance with ASTM F554 Grade 6. Headless anchor bolts for Adhesive shall be threaded full length. Cutting of reinforcing steel is permitted for drilled hole installation. All anchor bolts shall have single self-locking hex nuts. Tack welding of the nut to the anchor bolt may be used in lieu of self-locking nuts. All nuts shall be in accordance with ASTM A56 or ASTM A94. Flat Washers shall be in accordance with ASTM F46 and Plate Washers (for long slotted holes only), shall be in accordance with ASTM A6 or ASTM A709 Grade 6. After the nuts have been snug tightened, the anchor bolt threads shall be distorted to prevent removal of the nuts. Distorted threads and tack welds shall be coated with a galvanizing compound in accordance with the Specifications. RESILIENT AND NEOPRENE PADS: Resilient and Neoprene pads shall be in accordance with Specification Section 92, except that testing of the finished pads shall not be required. Neoprene pads shall be durometer hardness 60 or 70. JOINTS: All fixed joints are to be welded all around and ground smooth. Expansion Joints shall be spaced at a maximum of 0-0". Field splices similar to the expansion joint detail may be approved by the Engineer to facilitate shipping and handling, but rails must be continuous across a minimum of two posts. Only use the Continuity Field Splice (Detail "E") to make the railing continuous for unforeseen field adjustments. WELDING: All welding shall be in accordance with the American Welding Society Structural Welding Code (Aluminum) ANSI/AWS D.2 (current edition). Filler metal shall be either ER58, ER556 or ER5556. Nondestructive testing of welds is not required. SHOP DRAWINGS: Complete details addressing project specific geometry (line & grade) showing post and expansion joint locations must be submitted by the Contractor for the Engineer s approval prior to fabrication of the railing. Shop drawings shall be in accordance with the Specifications. PAYMENT: Guiderail shall be paid for under the contract unit price for Pipe Guiderail (Aluminum), LF (Item No. 55--2). Payment for the Guiderail will be plan quantity measured as the length along the center line of the top rail, and includes rails, posts, rail splice assembly, base plates, anchor bolts, nuts, washers, resilient or neoprene pads and all incidental materials and labor required to complete installation of the Guiderail., unless 0/0/ 20 870
