Description
Cost items' CostQuantities are able to link to the quantities referenced by quantity sets of a product, process, or resource. This basically allows for parametric costing - when you update a quantity of a product, process, or resource, the costs are also updated automatically.
Quantity sets for products and resource exists... but not process. It seems this has been left out.
I propose a new Qto_TaskBaseQuantities. There needs to be some IfcQuantityTime in there. Potential quantities I can think of include:
- WorkingDays
- CalendarDays
- WorkingHours (calculating using working days multiplied by Pset_WorkControlCommon.WorkDayDuration, or use 8 as default)
- ManHours (calculated using IfcConstructionLabourResource)
