Internal dominant face
According to the International Property Measurement Standards (IPMS): Office Buildings, published by the International Property Measurement Standards Coalition (IPMSC) in November 2014, the internal dominant face is:
|The inside finished surface comprising 50% or more of the surface area for each vertical section forming an internal perimeter.|
Where, the vertical section is ‘Each part of a window, wall or external feature of an office buildings where the inside finished surface area varies from the inside finished surface area of the adjoining window, wall or external construction feature, ignoring the existence of any columns.’
NB RICS property measurement, 2nd edition, published by the Royal Institution of Chartered Surveyors (RICS) in January 2018, defines the Internal Dominant Face (IDF) as: ‘The internal finish comprising more than 50% of the floor to ceiling height for each IDF Wall Section. If such does not occur, the Finished Surface is deemed to be the IDF.'
