EVM (Earned Value Management) is a Julia package for forecasting construction costs.
EVM consists of one function, forecast, which requires four inputs:
start date - Anticipated start date.
cost - Total projected cost.
days - Total projected project length in days.
rate - Percentage rate of construction management (income).
There are also four optional arguments that can be used to adjust the shape of the S-curve and smooth out the costs as needed for budget planning:
cost_fraction = 0.4 - The fraction of total cost expected to be spent at 50% completion. This is set to the typical spend for ground infrastructure.
peakedness_fraction = 0.8 - The maximum annual cost.
start_buffer = 90 - Time lag for project start from anticipated start date.
end_buffer = 120 - Time lag for project completion from anticipated end date.
