tt"10N pAC1�IC The above are hereinafter referred to as "pipe culverts ". Pipe culverts shall be assembled and installed in accordance with these Specifications and Chapter 1, Part 4 of the current American Railway Engineering and Maintenance of Way Association (AREMA) Specifications for culvert installation and UP Bridge Standard Plan No. 680000, Sheets 1 and 2, Plan No. 680020, Sheets 1 and 2 and Plan No. 680030, Sheets 1 of 1. The most restrictive provisions shall govern when there are differences in the requirements. 8.22.01 PIPE CULVERT MATERIAL - All pipe culverts will be furnished with annular corrugations and the exposed ends of all corrugated pipes shall be square, 3" x 1" annular corrugations shall be used for all CSP pipes with 36" diameters and larger; 2 -2/3" x 1/2" or 3" x 1" annular corrugations shall be used for 30" diameter CSP pipes. 3" x I" annular corrugations shall be used for all CAA? pipes. CSP and CAPP material furnished by the Industry, must meet the standards for pipe culverts set forth in Chapter 1, Part 4 of the current AREMA Manual for Railway Engineering, and UP Company Bridge Standard Plan No. 680000, Sheets 1 and 2 and Plan No. 680020, Sheets 1 and 2, or as required and approved by the Engineer. 6" x 2" annular corrugations and a Minimum of 4 bolts per foot shall be used for all SPP pipes. SSP material and connecting material shall be per the current AREMA Manual of Railway Engineering, chapter 1, part 4, Section 6 and UP Company Bridge Standard Plan No. 680030, Sheets 1 of 1. Any deviations of these Specifications are to be submitted to the Engineer for approval prior to starting construction. 8.21.02 HANDLING OF PIPE CULVERT MATERIAL - The Industry shall handle pipe culverts and the pipe culvert material carefully in order to prevent damage, including, but not limited to, distortion of the pipes, iniury to bituminous and other pipe culvert coatings. Pipe culverts shall never be dragged over the ground, but shall be handled with skids, rolling slings, or cranes. The Industry shall promptly repair, to the satisfaction of the Engineer; any damage to the pipe culvert or pipe culvert material. in the event such damaged pipe culverts or pipe culvert material cannot be repaired to the satisfaction of the Engineer, replacement pipe culverts or pipe culvert material must be provided by the Industry. 8.21.03 EXCAVATION AND LOCATION - Pipe culverts shall be placed in excavations at the location, elevation and alignment shown on the Drawings and as staked. The Industry shall preserve all stakes until pipe culvert installation is complete. Prior to pipe culvert excavation, embankment must be constructed to a height no less than two feet (2') above the top of the proposed pipe culvert. When embankment is placed, alternate methods may be used if approved by the Engineer. Pipe culvert excavations shall be wide enough to permit thorough compaction of the backfill under and around the pipe culvert as required by Section 8.21.10. The BASE WIDTH of the pipe culvert excavation shall not exceed the external width of the pipe culvert plus: a) 12 inches on each side for pipes less than 48 inches in diameter b) 18 inches on each side for pipes 54 -78 inches in diameter c) 24 inches on each side for pipes 84 inches in diameter or larger Pipe culvert excavation shall be deep enough to permit compliance with Section 8.21.05. Care shall be taken to insure drainage is diverted away from the pipe bed during preparaiion. The
