When either corrugated steel pipe or pipe arches with 5 inch × 1 inch corrugations are shown on the Plans, the Contractor may substitute pipe or pipe arches of the same thickness with 3 inch × 1 inch corrugations at no additional compensation. 601.0 3 GENERAL REQUIREMENTS . Care shall be exercised when unloading pipe s from delivery trucks and moving pipe s to their final position . If the Engineer rejects damaged pipe, new pipe shall be furnished by the Contractor at no additional cost to the Agency. Unless otherwise directed by the Engineer, the Contractor shall provide for the temporary diversion of water to permit the installation of the pipe in a reasonably dry trench. The location of all pipe installation s shall be approved by the Engineer.

6-2 Where existing pipe is to b e retained or re -laid and it becomes damaged due to the fault of the Contractor,

it shall be replaced with new pipe at the Contractor’s expense. Aluminum, aluminized, or aluminum -zinc alloy coated pipe that is to be in contact with concrete or mortar shall have the contact surfaces thoroughly coated with an approved barrier coating recommended by the pipe manufacturer or approved by the Agency’s Materials Testing and Certification Section . This coating shall be dry before installation. Where the protective coating has been removed from the metal, either by cutting, burning, welding, placing, or any other means, it shall be repaired by thoroughly cleaning with a wire brush and treating the damaged areas in accordance with AASHTO M 36 or in accordance with AASHTO M 245 for damaged polymeric coating s. 601.0 4 EXCAVATION . Where pipe is to be laid below the existing ground line, a trench shall be excavated to the required depth and to a width sufficient to allow for joining of the pipe and compaction of the bedding and backfill material under and around the pipe. The complet ed trench bottom shall be firm for its full length and width. If shown on the Plans or directed by the Engineer, unsuitable foundation material encountered below the normal grade of the culvert bed shall be removed and replaced with granular backfill for s tructures , or other specified or approved material . Bedrock, rocky or gravelly soil, hard pan, or other unyielding foundation material encountered at the normal grade of the culvert bed shall be removed and replaced with granular backfill for structures to a width equal to the inside diameter of the pipe plus 24 inches and to a minimum depth of 12 inches below the pipe grade, unless otherwise shown on the Plans or directed by the Engineer. 601.0 5 PLACEMENT . No pi pe shall be placed until the trench and the prepared foundation have been approved by the Engineer. Placement shall begin at the outlet end . The bottom of the pipe shall be in contact with the bedding throughout its full length . Bell or grooved ends of rig id pipes and the outside circumferential laps of flexible pipe shall be placed facing upstream . The longitudinal laps or seams of riveted pipe shall be at the sides. The handling holes in concrete pipes shall be filled with a precast plug, sealed, and cove red with mastic or mortar.

6-3 601.0 6 Joinin G Pipe.

6-4 (b) Metal Pipe . Metal pipes shall be firmly joined by coupling bands.

Pipes with an eff ective diameter greater than 36 inches shall be joined by coupling bands that fully engage the second full corrugation from the end of each pipe. Pipes on steep grades (greater than 14%) will be joined either by 24 inch wide coupling bands or by bands addi tionally equipped with silo rods or cables for positive attachment. In all cases, ends of pipes joined by coupling bands shall be as close together as the corrugations will allow.

6-5 All pipes shall be protected by a cover of fill 4 feet thick before heavy equipment or traffic is permitted to

cross during construction. Whenever this cover extends above the subgrade, the Contractor shall temporarily place earth which shall be removed when necess ary to complete the work in accordance with the details shown on the Plans or as directed by the Engineer. Any deviation from this practice shall have prior approval by the Engineer. However, compliance with the 4 -foot protective cover requirement shall not relieve the Contractor of any responsibility concerning damage to the pipe. 601.0 8 CLEANIN G CULVERTS . Pipe culverts at the locations shown on the Plans, or as directed by the Engineer, shall have the silt, debris, and other material removed and disposed of by methods that do not damage the pipe. With the approval of the Engine er, all or part of a pipe designated to be cleaned in place may be removed, cleaned, and re -laid in accordance with these specification s. In these cases, the Contractor shall furnish all material required to replace damaged pipes and joints, perform all ex cavation and backfill, and re -lay the pipe, all at the Contract unit price for Cleaning Culvert Pipe, In -Place. However, if the Engineer determines that the pipe must be replaced, through no fault of the Contractor, replacement will be paid for under the a ppropriate Contract item s. 601.0 9 METHO D OF MEASUREMENT . The quantities of culverts and storm drains to be measured for payment will be the number of linear feet used in the complete and accepted work , as shown on the Plans or as ordered by the Engineer . No allowance will be made for growth in length at joints when this increase exceeds the ordered length. When it is necessary to cut pipe in the field, the quantity of pipe to be measured for payment will be the length necessary, rounded up to the next whol e foot increment. The quantity of Re -Laying Pipe Culverts of the size specified to be measured for payment will be the number of linear feet of pipe re-laid in the complete and accepted work . The quantities of pipe elbows and end sections to be measured for payment will be the number of each size and type of unit installed in the complete and accepted work . The quantity of Cleaning Culvert Pipe, In -Place to be measured for payment will be the t otal length of pipe for each pipe acceptably cleaned, as determined along the flow line of the pipe . The cost to clean material from pipes as the result of on -project construction activities shall be at the Contractor’s expense.
