The scope of a cost schedule risk assessment (CSRA) typically includes identification of risks, prioritization of risks, determining planned risk responses, and quantitatively calculating cost and schedule contingencies based on a targeted confidence levels. IGE CSRA processes for public projects follow U.S. Army Corps of Engineers (USACE) Engineer Regulation (ER) 1110-2-1150, Engineering and Design for Civil Works, ER 1110-2-1302, Civil Works Cost Engineering, and Engineer Technical Letter 1110-2-573, Construction Cost Estimating Guide for Civil Works. In addition, IGE completes CSRA efforts on private projects based on enterprise thresholds and tolerances.
