Software certified by PACP (Pipeline Assessment Certification Program) is required to generate and import a standard database file that is fully compatible with PACP. Contractors and system owners across the country have invested in PACP-certified software for data collection. Many of those system owners have taken the additional step of acquiring NASSCO-certified Asset Management software to most effectively use the PACP data collected to project future rehabilitation needs and budgets.
For many years, visual inspection was the standard method to verify that a manhole coating application met project specifications and objectives.

Submerged assets such as outfalls, siphons, and force mains have historically been much more difficult to inspect due to the inability to remove these assets from 24/7 service, and due to the technology limitations that hinder a detailed inspection while in service.
