Appropriateness of Processes Followed

This part of the review checks the quality of the processes followed to reach capital expenditure decisions.

The key elements are:

• Renewal strategy for the continuation of the existing asset stock
• Maintenance plan or blend to support this asset stock and the performance of the portfolio
• Improvement programs where savings can be made by better investment in capital
• Augmentation enlargement programs to accommodate growth in the demand for the service.

In short, the review process needs to ensure that we have chosen:

• The right project solution - lowest sustainable life cycle cost option
• At the right time
• For the right reasons.

In all cases, the availability of high quality, accurate data is vital to the success of this process. The increase in sophistication of analysis is a reflection of the increased level of detail and integration of data systems.
