Example: A building project is estimated to have a cost at completion of $$920,000.$ At the end of month $4,$ the external walls were completed & the internal walls were started, and the scheduled cost was $$523,000$ while the actual cost spent was $$540,000.$ Assuming that internal walls is a long activity $($can be reported with $20\%$ progress$),$ and based on the following Incremental Milestone schedule

Calculate at the end of month $4$: $($Please show your calculations$)$

$1)$ Earned Value.

$2)$ Schedule & Cost Variance, SPI & CPI.

$3)$ Forecasted cost at completion assuming progress rate to date will prevail in the future.
