How often should your laser measure be calibrated ?
- Check prior to use
- Every 12 months
- If gaining incorrect measurements
What are the tolerances of your equipment ?
This would depend on the equipment and the range.
What is the international property measurements standards IPMS ?
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.
Can you give me some example of inclusion and exclusion for GEA ?
Inclusion • Wall thickness • Column’s piers and lift spaces • Internal balcony’s • Garages • Loading bays
Exclusions
• Greenhouses
• Canopies
• Fire escapes
Can you give me some example of inclusion and exclusion for GIA ?
Inclusions • Garages • Conservatories • Entrance halls • Internal walls • Service accommodation such as toilets Exclusions • Perimeter wall thicknesses • Fire escapes
• Can you give me some example of inclusion and exclusion for NIA – net internal area the useable internal area
Inclusions
• Entrance halls
• kitchens
Exclusions • Common areas • Toilets • Shared access • Circulation spaces • Fire escapes • Vehicle parking
Why did you use GIA for the reinstatement valuation ?
As part of the BCIS (building cost information service) the input methods per floor relating to the GIA to calculate a price per m2 along with other information regarding materials and any additional items that would be incorporated into the costs.
Under GIA what is usable area ?
An area is useable if it can be used for any sociable purpose in connection with the premises are used for .
When should GEA be used ?
Town planning, rating and council tax and in some building cost estimation
What is excused from GEA ?
Exclusions
• Greenhouses
• Canopies
• Fire escapes
How do you measure wall thickness ?
A mixture of opening and reveals
What are the advantages of using laser scanners in old buildings ?
Provides a point cloud data that can be reviewed and higher accuracy
What’s IPMS 1 2 and 3?
- IPMS 1, which equates closely to the former GEA (gross external area).
- IPMS 2 – Office, which equates closely to the former GIA (gross internal area).
- IPMS 3 – Office, which equates somewhat to the former NIA (net internal area).
What is an internal dominate face ?
The internal finish comprising more than 50% of the floor to ceiling height for each IDF Wall Section. If such does not occur, the Finished Surface is deemed to be the IDF.
When using a theodolite what checks should you carry out prior to use ? the
- Calibration in date
- Bubble / level check
- Battery and storage
- Security checks suitable for the area
What is the difference between IPMS and Standard Measurement Practice
The biggest difference is the replacement of terminology. IPMS will include all measurements but will categories certain items so that they can be valued at a different rate.
Where would you use IPMS1 ? How does this differ from GEA ?
Usually for planning reasons or building cost estimates. IPMS brings in standards to measure the wall up to the internal dominant face.
Where would you use IPMS2 ? How does this differ from GIA ?
Intended to be the same as GIA but categorises different areas if they have lower heights, smaller floor areas, open atriums, balconies, lifts etc.
Where would you use IPMS3 ? How does this differ from NIA ?
Internal columns are now included whereas before they were not.
How do you mitigate measuring errors ?
I will take the measurements of the walls but I also use triangulation to confirm measurements when I am back on site. I will also take measurements multiple times and average them particularly on larger distances where small changes can make a big difference in the total length.
What do you refer to when inspecting an office?
What measurements do you record for completing an RCA?
Can you tell me the differences between, GIA, NIA, and GEA?
It is the International Property Measurement Standards which are being adopted by RICS. They have been adopted for residential and office measurement by RICS
Reference to your standard template, generally GIA. Check RICS GN
- Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level
- Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor
- level.
- Gross External Area is the area of a building measured externally at each floor level.
