Measurement Flashcards
What is the Code of Measuring Practice?
A RICS best practice documentation on how to measure properties for different purposes and on different bases of measurement, including GEA, GIA and NIA.
What is Property Measurement 2018?
This professional standard introduced IPMS for office and residential buildings. It should be adopted if applicable and only deviated from if the client specifically requests or if all comparable evidence is in accordance with COMP.
What is IPMS?
International Property Measuring Standards
What is the difference between IPMS 3 and NIA?
IPMS 3 measures to the IDF rather the internal face of the perimeter walls. Columns, areas less than 1.5m of height and occupant’s share of party walls are included but stated separately.
What are some IPMS definitions?
IDF
IDF wall section
Component Area
Common Facilities
Finished surface
What is GEA?
Gross external area - Used for planning and build cost estimations. Excludes open vehicle parking areas, roof terraces, external covered ways, fire escapes, greenhouse.
Would you always use IPMS?
Yes - Unless the client requests otherwise or all comparables are in COMP.
What is dual reporting?
Reporting on both IPMS and COMP - best practice when asked not to adopt IPMS.
What is GIA?
Area of a building measured to the internal face of the perimeter walls at each floor level. Exclusions - Perimeter wall thickness, canopies, external covered ways, greenhouses.
What is NIA?
Usable area within a building measured to the internal face of the perimeter walls at each floor level. Exclusions - Entrance halls, toilets, lift/plant rooms, circulation areas, internal structural walls, areas with headroom less than 1.5m.
What is a standard site coverage?
40%
What electricity should be used in industrial units?
3 Phase

What are some types of AC?
- VAV (Variable air volume) high cost but most flexible

What is zoning?
Method of calculating the market rent for a shop by dividing a retail unit into separate zones of 6.1m. Zone A at the front is reflected as the most valuable.
Why would you measure a retail unit in NIA?
In accordance with COMP and for consistency with comparable evidence.
How would you measure an office building?
Depending on the purpose but typically NIA.
Why did you measure the Church in GIA?
Whilst it’s not specifically mentioned in the COMP it is industry standard when carrying out a valuation therefore the comparable evidence will only be accurate when applying this basis.
What tools would you use to measure?
Distometer
Tape measure
Trundle wheel
Drawbacks of a disto?
Can be distorted in bright light
Requires recalibration
Does have a 1.5mm margin for error
What is IPMS All Buildings?
It is a published document that is aiming to increase transparency in all RICS members when measuring so it can be implemented globally. Not yet adopted but when/if it will supercede the current IPMS standards.
What is your opinion on IPMS?
I believe it is a good thing to promote consistency in global measurement, however there has been resistance with RICS members and I do not see this changing in the short term.
