Measurement Flashcards
What are key RICS documents regarding measurement?
- RICS Property Measurement 2nd Edition 2018
- RICS Code of Measuring Practice 6th Edition 2015
When was RICS Professional Statement 2nd Edition 2018 effective from?
1 May 2018
GEA
Gross External Area
The area of a building measured externally at each floor level
GIA
Gross Internal Area
The area of a building measured to the internal face of the perimeter wall at each floor level
NIA
Net Internal Area
The useable area of a building measured to the internal dominant face of the perimeter wall at each floor level
IPMS
International Property Measurement Standards
Published by International Property Measurement Standards Coalition 15 Jan 2023
Benefits of IPMS?
- worldwide consistency
- increased transparency
- easier portfolio benchmarking
- facilitates international trade in property
Component Area in IPMS
One of the main elements into which the floor area can be divided
There’s A, B1, B2, B3, C, D, E, F, G, H
If a component area is multifunctional in use, what should it be stated as?
State according to principle use
What properties does IPMS currently apply to?
All buildings, regardless of their use or occupation
Used to be Offices and Residential as per Property Management 2018 but this needs updating
Dual Reporting
Reporting in terms of IPMS and another basis
Can only do this with good reason, EG all comparable evidence is NIA/GIA/GEA so need to compare like with like
When should dual reporting be adopted
When there is not enough comparable evidence using the same basis, so the client requests another standard is used as well
Benefit of dual reporting?
Facilitates comparative analysis both locally and globally
IPMS 1
The sum of the area of each floor level of the building measured to the outer perimeter of external construction features and reported on a floor-by-floor basis
What measurements are included but stated separately in IPMS 1?
- internal balconies
- external balconies
- accessible rooftop terraces
What areas are excluded in IPMS 1?
- external car parking
- external stairways
- open light wells
- patios
Why did RICS change from Code of Measuring to Property Measurement?
Provides a globally consistent measurement practice
Difference between IPMS 1 and GEA?
- internal balconies included in GEA, stated separately in IPMS 1
- external balconies excluded in GEA, stated separately in IPMS 1
- accessible rooftops are excluded in GEA, stated separately in IPMS 1
IPMS 2
The sum of the area of each floor level of an office building measured to the Internal Dominant Face and reported on a Component-by-Component basis
What measurements are included but stated separately in IPMS 2?
- internal balconies
- accessible rooftop terraces
What areas are excluded in IPMS 2?
- external car parking
- external stairways
- open light wells
- patios
Difference between IPMS 2 and GIA?
- internal balconies are included GIA, stated separately in IPMS 2
- external balconies are excluded GIA, stated separately in IPMS 2
- accessible rooftop terraces are excluded GIA, stated separately IPMS 2
- areas occupied by reveals of windows at internal dominant face are excluded in GIA but included in IPMS 2
IPMS 3
The Floor Area available on an exclusive basis to an occupier, but excluding Standard Facilities, and calculated on an occupier-by- occupier basis
Standard Facilities
Areas of a building that provide shared facilities and typically do not change over time
EG stairs, lifts, toilets, cleaner cupboards, plant rooms
What is included in IPMS 3?
- internal walls and columns
- half the common wall as measured to centre line when there is adjacent wall
What measurements are included but stated separately in IPMS 3?
- internal balconies
- accessible rooftop terraces
- areas under 1.5m
What areas are excluded in IPMS 3?
Standard facilities
Difference between IPMS 3 and NIA?
- internal walls and columns are excluded NIA, and included IPMS 3
- common walls measured to dominant face in NIA, and to centre line in IPMS 3
- enclosed walkways/passages excluded NIA and included IPMS 3
Limited Use Areas
- certain areas in building that cannot be legally or effectively occupied due to legislation
- vary between markets
- not specified by RICS but examples include limited light / restricted height
Internal dominant face
Inside finished surface of a wall
What does GEA include?
- perimeter wall thickness
- external projections
- columns
- balconies
- plant rooms
- areas under 1.5m
What does GEA exclude?
- external balconies
- external car parks
- external stairs
