LCCA Procedures

This section identifies the procedural steps involved in conducting a life-cycle cost analysis (LCCA). They include:

1. Establish alternative structure design or repair strategies for the analysis period or service life.

2. Determine performance periods and activity timing.

3. Estimate costs.

4. Develop expenditure stream diagrams.

5. Compute net present value (NPV).

6. Analyze results.

7. Re-evaluate design or repair strategies.

Once all pertinent costs have been established and discounted to their present value, the costs can be summed to generate the total life cycle cost of the project alternative. After this has been done for all the viable project alternatives, a summary of the results will be prepared see figure 12.13 for the Flowchart and LCCA Module implementation in STADIUM software. The summary of project alternatives should compare the total life cycle costs of initial investment, operations, maintenance and repair, replacement, and residual value of all the project alternatives.
