Cost Item (Measaured)

Information below is provided by the role Cost Modelling through the functional part fp_model_cost_item

A cost item should be defined for the area quantity. This cost item brings together the area, the unit cost for the area and all the relevant cost factors and provides a result that is the overall cost value for the building. Note that it is possible to deal with multiple areas in which case each area considered should be dealt with as a separate, named cost item.
Cost item information includes:

Each cost item should have the unit cost basis identified by the unit type 'AREAUNIT' and have units named according to the measurement system used. e.g. METRE for SI units or FEET for imperial units. A dimensional exponent for length of 2 should be set to identify area measurement; other dimensional exponents should be set to 0.
The value of the cost item should be asserted. For 'preliminary appraisal' costing, the value of the cost item will be the relevant area of the building multiplied by the unit cost value of the area and the cost factors that are to be applied. A resulting cost value giving the total cost is applied to the cost item.
Each cost item should be named as appropriate Refer to locally extended exchange requirements for further details of agreed cost types and cost item names.
Each cost item used may have a further description associated to further define the meaning of the item
Each cost value captured within the cost item must also have a type assigned. For 'preliminary appraisal' costing, the types will include unit area cost and total area cost.
The date on which the cost value is applicable should be asserted.
If there is a limit to the time for which a cost is applicable, it should also be asserted.
