• Cracks greater than or equal to 1/8 inch in width or greater than or equal to 6 inches in length require a pipe analysis and a remediation plan for repair or replacement as specified in Section 601.3(p).
3.c Holes. Note all holes in the inspection report.
• Holes with a diameter less than 1/2 inch without water leakage or soil infiltration will be accepted.
• Pipes with diameters greater than 30 inches having holes with a diameter less than 1/2 inch which exhibit either water leakage or soil infiltration require an internal repair patch as shown in POM C.6.11.
• Pipes 30 inches and less in diameter having holes with a diameter less than 1/2 inch which exhibit either water leakage or soil infiltration require a remediation plan for repair as specified in Section 601.3(p).
• Pipes with diameters greater than 30 inches having holes with a diameter greater than or equal to 1/2 inch but less than 1.5 times the corrugation width require an internal repair patch as shown in POM C.6.11.
• Pipes 30 inches and less in diameter having holes with a diameter greater than or equal to 1/2 inch but less than 1.5 times the corrugation width require a remediation plan for repair or replacement as specified in Section 601.3(p).
• Holes with a diameter greater than 1.5 times the corrugation width require a pipe analysis and a remediation plan for repair or replacement as specified in Section 601.3(p).
3.d Deflection/Buckling . Note all deflections in the inspection report. Prepare and submit a pipe analysis and a plan for repair or replacement as specified in Section 601.3(p) if deflection is greater than 5% of the unloaded inside diameter of the pipe. If the pipe analysis provides a remediation method that will provide a structurally adequate pipe, then the pipe may remain at the elevated deflection, otherwise remove and replace.
in length at each location, perform final inspection as specified in Section 601.3(n). For all other 100 year design life pipe installations, perform final inspection as follows: Before final acceptance, inspect the entire length of all installed pipe types according to Table D with total backfill/embankment load applied. Perform inspection on pipes at least 30 days after backfill/embankment is completed. If the final wearing course is placed more than 30 days after the pipe backfill/embankment is completed, the inspection must be performed before placing the final wearing course. Provide the measurement equipment according to Table D to document the required items. Provide the required documentation of all inspections directly from the inspection service provider and/or data pr
