NOTESPIPE RAILING & POSTS:Structural Tube, Pipe and Bar shall be in accordance with ASTM B221 or ASTM B429, Alloy 6061-T6.End Rail 90 bends and corner bends with maximum 4’-0" post spacing, may be Alloy 6063-T6. Postsand End Rails shall be fabricated and installed plumb, – 1" tolerance when measured at 3’-6" abovethe foundation. Corners and changes in tangential longitudinal alignment, may be made continuous witha 9" bend radius or terminated at adjoining sections with a standard end hoop when handrails are notrequired. For changes in tangential longitudinal alignment greater than 45, posts shall be positioned ata 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 matchthe alignment radius.RAILING MEMBER DIMENSIONS TABLEOUTSIDEWALLDIMENSIONTHICKNESS2" NPS (Sch. 40)2.375"0.154"2" NPS (Sch. 40)2.375"0.154"Rail Joint/Splice Sleeves1b" NPS (Sch. 40)1.900"0.145"Handrails Joint/Splice Sleeves1" NPS (Sch. 40)1.315"0.133"Handrails1b" NPS (Sch. sHandrail Support Bar1" Round BarBASE PLATES:Base Plates shall be in accordance with ASTM B209, Alloy 6061-T6.SHIM PLATES:Shim Plates shall be aluminum in accordance with ASTM B209, Alloy 6061 or 6063. Shim plates shall beused for foundation height adjustments greater than14"and localized irregularities greater than18".Field trim shim plates when necessary to match the contours of the foundation. Bevelled shimplates may be used in lieu of trimmed flat shim plates shown. Stacked shim plates must be bondedtogether with adhesive bonding material and limited to a maximum total thickness of12",unlesslonger 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 0-01.dgnAnchor bolts shall be in accordance with ASTM F1554 Grade 36. Headless anchor bolts for AdhesiveAnchors 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 maybe used in lieu of self-locking nuts. All nuts shall be in accordance with ASTM A563 or ASTM A194. FlatWashers shall be in accordance with ASTM F436 and Plate Washers (for long slotted holes only), shall bein accordance with ASTM A36 or ASTM A709 Grade 36. After the nuts have been snug tightened, theanchor bolt threads shall be distorted to prevent removal of the nuts. Distorted threads and tack weldsshall 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 932, except that testingof 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 ata maximum of 30’-0". Field splices similar to the expansion joint detail may be approved by theEngineer to facilitate shipping and handling, but rails must be continuous across a minimum of twoposts. Only use the Continuity Field Splice (Detail "E") to make the railing continuous for unforeseenfield adjustments.WELDING:All welding shall be in accordance with the American Welding Society Structural Welding Code (Aluminum)ANSI/AWS D1.2 (current edition). Filler metal shall be either ER5183, ER5356 or ER5556. Nondestructivetesting of welds is not required.SHOP DRAWINGS:Complete details addressing project specific geometry (line & grade) showing post and expansion jointlocations must be submitted by the Contractor for the Engineer’s approval prior to fabrication of therd960rhrailing. 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.515-1-2). Payment for the Guiderail will be plan quantity measured as the length along the centerline of the top rail, and includes rails, posts, rail splice assembly, base plates, anchor bolts, nuts,11:46:45 AMwashers, resilient or neoprene pads and all incidental materials and labor required to completeLASTREVISION01/01/11REVISIO N12/30/2011installation of the Guiderail.DESCRIPTION:INDEXFDOT DESIGN STANDARDSFY 2012/2013ALUMINUM PIPE GUIDERAILNO.870SHEETNO.1
