Q

What are the main RICS Document in relation to measurement?

A

“RICS Property Measurement - PS - V2 - Jan 2018
Adoption of the IPMS standards for office and residential, others will be added as they are published and updated.
Internal dominant face, the surface comprising more than 50% of the floor to ceiling

RICS Code of measuring practice - GN - V6 - May 2015
Measurement for all other building that does not include office and residential.”

IPMS, All Buildings Jan 2023: IPMS All Buildings supersedes all previously published IPMSC standards for individual asset classes by utilising the concepts
and objectives contained in those specific versions of IPMS into one harmonised standard. IPMS All Buildings is applicable to
all types of Buildings independent of their use or their occupation.

Q

“What is the international property measurements standards IPMS ?”

A

“The International Property Measurement Standards Coalition (IPMSC) is a group of more than 80 professional and not-for-profit organizations from around the world, working together to develop and implement international standards for measuring property.

At present, the way property assets – such as homes, offices or shopping centers – are measured varies dramatically. For example, in some parts of the world it is established practice to include common space (lift shafts; communal hallways etc.) in floor area measurements; in others off-site parking might be included or even swimming pools.”

Beyond Zone C typically would be ancillary space and storag
