Classification Systems¶
Classification is important for facilitating uniform recording and use of construction products.

Field of application¶
Field of Application currently encompasses “Civil and Utility Construction” and “Ground, Road, and Water Construction.”
Classification System¶
There are various systems available to classify construction products. Currently, the NMD employs four classification systems:
NL/SfB (for “Civil and Utility Construction” (Burgelijke en Utiliteitsbouw, B&U)),
RAW (for “Ground, Road and Water Construction” (Grond-, Weg- en Waterbouw, GWW))
Processes (for processes in both fields),
Energy
Each of these systems has its own set of Elements and Components, which can be found in the document Functional Descriptions.
Element¶
An Element is a classification of a construction function. The GWW uses a different name for Element, though, called ‘Chapter’ (Hoofdstuk). But for consistency, the database uses the term Element in both cases.
