Forecast/BIM rules are exceptions that affect the expected job run times. You can manually revise the expected run time for a job by creating exceptions using the Forecast/BIM Rules in the Forecast domain. This method enables you to compensate for new or seasonal conditions that can affect the run time of a job, making its expected run time irrelevant. It also enables you to enter statistics for jobs that have not yet run and therefore do not have existing statistics. You can modify these statistics at any time.
You can do the following:
Create a Forecast/BIM rule: You can create and enable/disable the following types of Forecast/BIM rules:
Quantitative Resource: Enables you to update the maximum value of quantitative resources.
Job Run Time: Enables you to update the run time by changing the percentage or the run time, or by setting the time.
Condition: Enables you to define a specific time for adding a condition or a group of conditions to the Condition table. A Manual Condition Event occurs when a job depends on a condition that does not apply to other jobs and has not been added to the Condition table previously.
Confirmation: Enables you to define a time for the job's confirmation, increasing the accuracy of the calculation. Confirmation rules affect the entire calculation. If a job awaiting confirmation is connected to more than one service, any defined exception affects all services depending on it.
Edit Forecast/BIM Rule: You can edit the Forecast/BIM rules to manually revise the expected run time for a job. A Service Assumption is a Forecast/BIM rule for a specific service.
