Mentioned cost data is gross cost data.
The data is including contractor's surcharges and excluding design and engineering costs and value added taxes.
Contractors surcharges are:
- General costs on site;
- General costs;
- Profit and risk.
Cost data can be used only for budget estimating of large projects.
In the various tables, the following abbreviations are used:
- GFA: Gross Floor Area;
- RA: Roof surface area;
- BSA: Building surface area;
- BC: Building Content (volume).
The civil and civil-technical cost data are grouped according to the Dutch civil industryNL/SfB classification system.
The list below shows a review of the codes according to the classification system.For more information about the NL/SfB classification system see the report 'NL/SfB classification system of the Dutch SfB commission' published by the 'Bond van Nederlandse Architecten BNA' in Amsterdam.
