Measurement Flashcards
What are the key RICS documents regarding measurement?
- RICS Property Measurement, 2nd Edition 2018
- RICS Code of Measuring Practise 6th Edition 2015
When was RICS Professional statement 2nd Edition 2018 effective from?
May 2018
What is GEA
Gross External Area
The area of a building measured externally at each floor level
What is GIA
Gross Internal Area
The area of the building measured to the internal face of the perimeter wall at each floor level.
What is NIA
Net Internal Area
The useable area of a building measured to the internal dominant face of the perimeter wall at each floor level
What is IPMS
International Property Measurement Standards
Published by International Property Measurement Standards Coalition 12th Jan 2023
Benefits of IPMS?
- Worldwide consistency
- Increased transparency
- Easier portfolio benchmarking
- Facilitates international trade in property
What is the component area in IMPS?
These are horizontal areas within a building which are designated according to their structure and function. The areas will equal IMPS 1 for the building or level of a building being measured.
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.
What is Dual Reporting
Reporting in terms of IMPS and another basis.
This can only be done with good reason, for example the comparable evidence is in NIA/GIA/GEA so need to compare a like with like.
Benefit of dual reporting
Facilitates comparative analysis both locally and globally
What is 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. (In many markets this is referred to as GEA)
IMPS1- All classes of building
What should dual reporting be adopted?
When there is not enough comparable evidence using the same basis, so the client requires another standard is also used.
What measurements are included but stated separately in IMPS 1?
- Internal balconies
- External balconies
- Accessible rooftop terraces
What areas are excluded in IMPS 1?
- External car parking
- External stairways
- Open light wells
- Patios
Why did the RICS change from code of measuring to Property Measurement?
Provides a globally consistent measurement practise.
What is the difference between IMPS 1 and GEA?
- Internal balconies included in GEA, stated separately in IMPS 1
- External balconies excluded in GEA, stated separately in IMPS 1
- Accessible rooftops are excluded in GEA, stated separately in IMPS 1
What is IMPS 2?
IMPS 2 is the sum of the arears of each floor level of a building, measured to the internal dominant face, which may be reported on a component by component basis for each floor of a building .
IMPS 2- Residential
What measurements are included but stated separately in IMPS 2?
- Internal balconies
- Accessible rooftop terraces
What areas are excluded in IMPS 2?
- External car parking
- External stairways
- Open light wells
- Patios
What is the difference between IMPS 2 and GIA?
- Internal balconies are included in GIA, stated separately in IMPS 2
- External balconies are excluded in GIA, stated separately in IMPS 2
- Accessible rooftop terraces are excluded GIA, stated separately IMPS 2
- Arears occupied by reveals of windows at internal dominant face are excluded in GIA but included in IPMS 2.
What is IMPS 3?
The floor area avaliable on an exclusive basis to an occupier, but excluding standard facilities, calculated on a occupier by occupier basis.
IMPS 3- Office
What are standard facilities?
Arears of a building that provide shared facilities and typically do not change over time. For example stairs, lifts, toilets, cleaner cupboards and plant rooms.
What is included in IMPS 3
- Internal walls and columns
- Half the common wall as measured to centre line when there is a 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 IMPS 3?
Standard facilities
What is the difference between IMPS 3 and NIA?
- Internal walls and columns are excluded in NIA and included in IMPS 3.
- Common walls measured to dominant face in NIA and to centre line in IMPS 3.
- Enclosed walkways/ passages excluded in NIA and included in IPMS 3.
What are limited use areas?
- Certain areas in the building that cannot be legally or effectively occupied due to legislation.
- They vary between markets
- Not specified by RICS but examples include limited light and restricted height areas.
What is the internal dominant face?
the inside finished surface of a wall.
What does GEA include?
- Perimeter wall thickness
- External projections
- Columns
- Balconies
- Plant rooms
- Areas under 1.5,
What does GEA exclude?
- External balconies
- External car parks
- External Stairs
What is GEA used for?
