Final answer:
The best place to document the actual costs and the reasons for cost overruns, such as the unexpected increases in material prices in a project closeout report, would be in the cost management or financial summary section. Here you would detail the financial discrepancies between the planned and actual budget and draw conclusions about the estimated versus actual costs.
Step-by-step explanation:
When writing the closeout report for a project where the actual costs exceeded the planned budget, it is essential to document why these overages occurred. You specified that the actual costs totaled $87,500 compared to the estimated $80,000 budget, with the rise primarily due to unexpected increases in the price of materials. The best place to document this information would be in the section of the closeout report dedicated to cost management or the financial summary. This section discusses the initial financial assumptions, the final costing statement, and explanations for variance.
It is important to draw a conclusion regarding whether the results supported the estimated times and to discuss any unexpected outcomes. Specific events that led to the increase in material costs should be detailed, as they are crucial for understanding the project's financial variances. This information is valuable not only for this project's records but also for planning future projects more accurately.
