4.1.5.4 Element Covering 
Covering elements are assigned to their hosting elements using the Element Covering  concept.
EXAMPLE   A cladding is assigned to a wall, a flooring is assigned to a slab, a wrapping is assigned to a duct using the IfcRelCoversBldgElements   relationship. 
    The following diagram shows the generic classes and relationships used when applying this concept.
    
    In addition, concepts may have particular importance to common or standardised industry practices and scenarios. For these specific usage scenarios, the table below shows a recommended list of general usage patterns that users may adopt.
