6.1.4 Future Conditions Analysis

The purpose of safety analysis for future conditions is to consider safety implications of design decisions in the project development process. Future conditions analysis is conducted in a variety of different forms and analysis methods. Future conditions safety analysis methods may include:
  • Relative Comparison of CMFs for future conditions analysis; and
  • HSM Part C Predictive Method for future conditions analysis (various approaches)
