This document discusses the importance of inspecting storm pipes after installation. It notes that many municipalities and agencies now require post-installation inspections. The document outlines different inspection methods like video, profilers, and mandrels. It questions whether private systems should be inspected less than public systems. The benefits of inspection include identifying issues before failure occurs. Costs of inspections are around $1-1.50 per linear foot, much less than potential costs of repairs if issues are found later. Inspecting ensures pipes were installed properly according to specifications.

24. Do all contractors install all the pipe
properly and per the specification?

29. Is the soil embedment specified
always right for the pipe type used?

31. If it looks like a concern today,
how will it look tomorrow?

32. Storm Pipe
Post-Installation Inspection
• Imminent failure / structurally significant
issues less common
• Many issues not significant
• Most issues repairable
• FDOT / AASHTO guidelines
• Wouldn’t you rather know upfront?

34. Contractor Perspectives
• Quality contractors in favor of final
inspection
• Want reasonable, timely resolutions
• Define functional vs. cosmetic concerns
• Expected to execute based on EORs’
specifications
• Expect justified designs, not material
substitutions

35. Where it’s heading
• Video inspection reviews
– CEIs and / or Engineer of Record
– Even city and private projects
• Verify performance with engineer’s design
• Contractors challenging design
• Defining functional vs. cosmetic issues
• Material-specific designs and specifications
– Geotechnical
• Pre-Construction Meetings
– Better communication

of Pipe Inspection.

37. Post Installation Inspection Prices
• $1.00 to $1.50 per linear foot
• Dewatering and Some Cleaning/Jetting
• Contractor has trench dewatered already
• ~ 1 to 2% of total cost

38. Costs of Real Settlements /
Replacements
• $3,300,000 (11,000 ft. pipe, 36 – 60 inch)
• $325,000 (400 ft. 60-inch pipe)
• $47,500 (120 ft. 48-inch pipe)
