Abstract: A forecasting system is disclosed that allows a user to create a project or body of work, define attributes for that project, select relevant historical data from a repository of historical data, and create a project forecast by scaling the historical data appropriately. The project forecast may include costs and workforce utilization forecasts. The workforce utilization and supply-demand forecast data may be broken down by trade, and the system may provide demographic and geographic information relevant to the workforce. In order to provide a rich corpus of historical data, certified payroll reports, or other sources that provide data down to the level of the individual worker, may be used to generate the cost and workforce forecasts.
