The USACE Infrastructure Assessment (IA) Planning and Response Team (PRT) Program has 2 primary functions:

(1) Under FEMA Mission Assignment, the IA PRT augments local public works Applied Technology Council-20 (ATC-20) Post-Earthquake (or ATC-45 Post-Flood) rapid structural assessment capabilities (primarily residential).  These inspections function solely to determine the habitability of the structure - i.e. assessments apply a safety rating (red, yellow, green placards) to each structure inspected. 

(2) The IA PRT can also provide a management cell for a wide array of FEMA Technical Assistance/ad hoc missions (that do not otherwise have a PRT).  These missions can include: electrical, mechanical, geotechnical, structural engineering assessments; urban search & rescue (US&R) support; and water/wastewater infrastructure assessments and repairs.  

Note the core IA PRT does not contain inspectors per se.  For ATC-20/45 assessment applications, the PRT includes an ATC-20/45 Instructor who can provide “just-in-time” training to inspectors.  This training takes 6-8 hours.  Sources of inspectors include: USACE engineering communities of practice, Forward Engineer Support Teams (FESTs), contractors, retired annuitants, local public works, State assets, and other Federal agencies (e.g. Bureau of Reclamation).
