- What professional and guidance relates to property measurement
RICS property Measurement 2nd Edition, January 2018. Effective 1st May 2018
Code of measuring practice 6th Edition, May 2015- effective 1st May 2015
- What are the different method of measurements
Office- IPMS 1, IPMS 2, IPMS 3
Residential: IPMS 1, IPMS 2, IPMS3, IPMS3A, IPMS3B, IPMS3C
- What document would you reply on to measure industrial areas ?
Code of measurement practice 2015
- What type of measurement would you use when working out a site value ?
Gross internal Area
- What is GEA
Gross External Area is the area of a building measured externally at each floor
Used for planning applications, site coverage and calculating build costs on residential property for insurance purposes
- What is GIA ?
Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor.
Can be used for build cost estimation, estate agency and valuation.
- What is NIA ?
Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor level
- What is IPMS
International Property measurement Standards
- Which sectors have an IPMS ?
Residential and Office
- How are residential buildings measured?
[IPMS, GIA and GEA]
- What’s the difference between GEA and GIA?
GEA measures the perimeter of a building
GIA measures to the Internal dominant face within a building
- Do you include measurement of communal space in your development measurements?
Yes, only for the purpose of getting the IPMS2 or GIA of building on a floor by floor basis for build cost purposes.
- How did you measure a site/piece of land?
- How did you measure a site/piece of land?
Using a trundle wheel in Meters, Hectares and Acre
- Define IPMS 1 and when will you use it ?
The sum of the areas of each floor level of a building measured to the outer perimeter of external construction features, which may be reported on a component basis for each floor of a building.’
Used for planning purposes
- When will you use IPMS 2
The sum of the areas of each floor level of a residential building measured to the internal dominant face, which may be reported on a component by- component basis for each floor of a building. In many markets, but not universally, this is similar to gross internal area [GIA].’
Can be used for build costs.
- When will you use IPMS 3
Measure the occupation of building on an exclusive basis to an occupier
Used for marketing and valuation purposes.
- What is IPMS 3A
an external measurement of the area in exclusive occupation – equates somewhat to GEA (gross external area)
- What is IPMS 3B
an internal measurement including internal walls, etc. – equates somewhat to GIA (gross internal area)
Used for marketing and valuation purposes.
- What is IPMS 3C
an internal measurement excluding internal walls, etc.
– equates somewhat to EFA.
- How would you calibrate a laser measurer
Check a known distance and if it doesn’t show the correct distance then send to manufacturer. Results are to be recorded.
- What is a scale ?
A scale allows measurements to be taken from a paper plan & converted into real time measurements of a property or site. It is the relationship between a measurement on a paper plan or map and the corresponding distance on the ground
- What is an internal dominant face
‘The internal dominant face (IDF) is the inside finished surface comprising more than 50% of the floor to ceiling height for each IDF wall section. If such does not occur, then the finished surface is deemed to be the IDF
How many acres are in a hectare?
1 hectare = 2.47105381 acres
What is the accuracy of your digital measurer
Different brands have different accuracy.
The Leica disto d110 has. 1.5mm acurracy @ 60 m
What is the accuracy of an OS Map
TBC
How accurate must your measurement be ?
Should be between+/- 1% to +-10% may be expected depending on the type of property being measured. A greater margin of error is appropriate for a plot of land vs an office or residential.
What must be included in a measurement report ?
Provide a date of the measurement
State the measurement methodology
Provide reference and scale of any plans used
Stating conversion factors used to covert imperial to metric and any rounding.
What is the difference between ipms 1 and GEA ?
IPMS 1 = GEA + External balconies + roof terraces
GEA = IPMS 1 - External balconies - rooftop terraces
What is the difference between IPMS 2 and GIA
GIA = IPMS 2 - limited use area 1 - internal balconies - roof terraces
IPMS 2 = GIA + limited use areas + internal balconies + roof terraces
What is the the difference between IPMS 3 and NIA
nIA = IPMS 3 - limited use area - limited use area 2 - half of common walls - structural Collums - external balconies - roof terraces
IPMS 3 includes limited use areas common walls collums and external balconies
What is limited use area
Limited use areas are areas where special consideration may need to be applied for valuation or other purposes, such as areas with limited height.
Quantify separately
Limited use area 1- Area difference from internal dominant face
Limited use area 2- areas with limited height. Heights below 1.5m
How big is a hectare
10,000 square metre
How big is a acre ?
4046.86 square meters
What is the update on the IPMS retail, industrial and mixed use ?
Undergoing consultation on IPMS industrial, retail and mixed
What is the difference between IPMS 1 and GEA ?
Comparable, however balconies and roof terraces will be included.
What is the diffrence between IPMS 2 and GIA ?
Areas occupied by windows are measured to the glass if the area of the window covers more than 50% of the wall (Internal Dominant Face). includes conservatories.
Balconies included but stated separately
Covered Galleries, included but stated separately
accessible rooftops included but state separately
What is the diffrence between IPMS 2 and NIA ?
Columns are included; partitions on multi tenanted floors are measured to the middle of the partitioning.
What are the general exclusions from IPMS office and residential
External parking
Patios
Sheltered areas
In IPMS 3B Residential what is included but stated Separately ?
- Attics, basements/cellars
- Balconies and verandas in exclusive use
- Garages
- Limited use areas.

How would you deal with measuring a parcel or land or site ?
