Construction tab in model data
Additional cost data can be defined for each zone and surface using the controls under the Cost header on the Constructions model data tab.
Tip: The Cost data help topic provides an overview of the places in DesignBuilder where costs are entered.
In general the sub-structure cost is the cost of all works below ground level. The sub-structure cost data entered here is used at zone level and is multiplied by the zone sub-structure surface area, which is calculated as the sum of all ground floor areas in the zone, i.e. the sum of all floors with a ground adjacency.
Note: Additional substructure cost is included in below grade surfaces and their constructions.
Select the structure type to define the cost of the building structural elements per floor area. This data is used zone by zone when calculating total building structural costs. Structure costs appear in the report, depending on the cost model used, as follows:
Enter the cost of internal finishes for all walls (external and internal partitions) in cost per surface area. This should cover the cost of paint, wallpaper or any other material or process not already covered in the wall construction costs.
Enter the cost of internal finishes for all floors (external, ground and internal) in cost per surface area. This should cover the cost of paint, polish or any other material or process not already covered in the floor construction costs.
Enter the cost of internal finishes for all ceilings (internal and underside of external roof surfaces) in cost per surface area. This should cover the cost of paint, polish or any other material or process not already covered in the ceiling/roof construction costs.
