It doesn’t impact on the rental value of the space it impacts the way the area of the space is
reported. Only impact if comps are different metric

What is the main difference between IPMS 2 and GIA?
IPMS 2 includes reveals of windows, covered galleries, balconies and accessible rooftop terraces (but stated separately) whereas GIA excludes covered galleries, balconies and accessible rooftop terraces.
What are limited use areas and how do you report these?
An example of limited use areas is an area below
1.5m in height.
The reason IPMS brought about this term is because in certain markets there may be areas of a building that are incapable of legal or effective occupation, one market may classify an area as limited use where another may not. In any case, these are to be measured
and included but stated separately.
Previously excluded in Code of Measuring Practice.
Why has IPMS been introduced?
To bring uniformity to the way that property is measured and reported globally.
- CONSISTENCY
- TRANSPARENCY
Be able to compare like for like in different countries.
Lots of comparables are measured to NIA how do you allow for the difference with IPMS?
I check with the agent whether the property was measured on an IPMS3 or NIA basis and
then I always compare on a like for like basis.
Because IPMS has not been fully introduced into the region I am still measuring on both basis’s IPMS and NIA and dual reporting.

How do you calibrate a laser?
I have a distance in my office that I always check with the laser measurer before going out on
inspection, we also have a log book to log the measurements
Send it off for a yearly check to Bosch
What are the different types of instruments and the pros and cons of each?
Trundle Wheel – used for measuring land (not sand!)
Every circle = 1 metre
Advantages: do not require two people, can be a fast and practical
Disadvantages: design can prohibit from moving in a straight line if not used at the right angle
which adds more distance, it has a short handle so it is difficult for tall people
Laser distance meter - (Bosch)
Advantages: Fast and effective, don’t have to walk there and back, can be used on your own
Disadvantages: cannot be used in sunlight, can only measure so far
Tape measurer – can be used for small distances such as the door or window width in an
office
Advantages: easily manoeuvrable can measure corners or curves, no power/batteries needed
Disadvantages: cannot measure large distances, sagging can cause inaccuracy and need
two people
