SECTION 509 -STRUCTURAL PLATE PIPES, PIPE ARCHES, ARCHES, AND M ETAL BOX CULVERTS 5-106
509.01 Description This work shall consist of furnishing and i nstalling structural plate
pipes, pipe arches, arches, and metal box culverts in accordanc e with these specifications and in reasonably close conformity with the lines and grades sh own in the Contract Documents.
509.02 Materials Material shall meet the requirements of the f ollowing Sections of
Division 700 — Materials:
Asphalt Filler for Structural Plate Arches 702.09 Steel Structural Plate Pipe, Pipe Arches, Arches, Box Culverts and Fasteners 707.09 Aluminum Alloy Structural Plate Pipe, Pipe Arches, Arches, Box Culverts and Fasteners 707.14
509.03 Fabrication Structural plate pipes shall be circular wi th a vertical elongation of
approximately 5 percent, unless otherwise specified on the Plan s. Plates shall be formed to provide lap joints for bolted assembl y. Joints shall be staggered so that no more than three plates come together at on e point. Bolt holes shall be made so that all plates having like dimensi on, curvature and the same number of bolts per foot of seam shall be interchangeable. Eac h plate shall be curved, before assembly, to the radius necessary to produce the final c ross section called for. End plates shall be neatly cut to the skew and slope shown on t he Plans. Burnt edges shall be free of oxide and burrs, and shall be completely galva nized. Special plates and part plates shall be legibly marked to correspond to markings on an erection/assembly diagram, which shall be furnished by the C ontractor. The Contractor sha ll prepare and submit Shop Drawings, erection/assembly diag rams, or other necessary Workin g Drawings in accordance with Section 105.7. These drawings will be reviewed and approv ed in accordance Section 105.7. Bolt holes along those edges of the plates that will form longi tudinal seams in the finished structure shall be staggered in 2 rows, 2 inches apart for steel structural plates and shall be in 2 rows, 1¾ inch apart for aluminum structural plate s. Holes shall be in the valley and crest of the corrugations. Bolt holes along those edges of the plates that will form circumferential seams in the finished structure shall be no mor e than 12 inches apart. The distance from the center of a hol e to the edge of the plate sha ll not be less than 2 times the diameter of the bolt. The nominal diameter of the bolt holes, not including corner holes in the longitudinal seam, shall be ⅛ inch greater that the diamete r of the bolts.
509.04 General Excavation for the structure and for the beddin g material shall be in
conformance with Section 206 - Structural Excavation. Structures shall be assembled in the sequence and manner recomm ended by the manufacturer and in such a way t hat no distortion of plates wou ld occur. Bolts of the
