Final Validation & Rating of CIP Programs

All of this information helps the decision on the relative accuracy of CIP programs. In some cases reporting on the programs is all that is required. In other cases, adjustments to the capital works program will show the changes considered likely to occur if improvements were made where weaknesses have been identified. The review team should develop a spreadsheet broken down into the key elements of the capital works expenditure program. They should model the variations or scenarios for the improvements and then model the revised capital expenditures. The level of confidence in the CIP program should be high (95%) for the period of the current tariff - three to five years, with a lower confidence (say 80%) being achieved for proposals for the next 25 years. A much lower level of confidence (70%) is more realistic for project proposals beyond this period.
