The Infrastructure Sustainability (IS) rating tool continues to evolve after its release date. Updates to the IS rating tool are listed on the 'IS Rulings' spreadsheet and are an essential component of the rating tool. The spreadsheet lists 5 types of updates: corrections; Technical Clarifications (TCs); Credit Interpretation Requests (CIRs); documentation and withdrawn rulings. It is vital to understand the relevance of these changes as they may impact the assessment of your project/asset.
