What measurement basis would you use for office property?
NIA or IPMS1-3
What measurement basis would you use for industrial property?
GIA
What measurement basis would you use for retail property?
GIA
how does RICS Property Measurement differ from the old code of measuring practice?
Introduces IPMS to avoid current inconsistencies in different countries
Improve global transparency
Replaces the measurement of offices and residential in the RICS Code of Measuring Practice
Why is accuracy important when you measure buildings?
To ensure there are no miscalculations or errors in the later prupose for which the measurement was carries out
→ e.g in rating, building cost, SC apportionment
Tell me how you use floor plans to facilitate measuring buildings?
To help understand layout and plan what should / shouldn’t be included within the measurement
To confirm measurements using scale
How do you calibrate a laser measurer (disto)?
- Establish a constand baseline → easy to access / not long in length. → measure with accurate steel rule
- Place disto on tripod or flat/secure surface and take the measurement from baseline at least 10 times
- Average the values measured and calculate the standard deviation
Why do you take check measurements?
To ensure accuracy of your measurements and equipment
Tell me about strength and weakness of a measuring technique you have used
Disto
Strength: accurate, straight, fast to use
Weakness: Delicate → precise calibration must be maintained. → dropping can cause inaccuracy
When would you use a tape measurer?
To measure small distances
Calibrate disto
Confirm disto measurements
When would you use a trundle wheel?
To measure a plot of land for valuation purpose
What is a potential source of error when measuring?
Human error:
Misreading, unsure what to include/exclude
Equipment error: check / calibrate annually
What is IPMS?
International Property Measurement Standards
Why has IPMS been introduced?
- Avoid current inconsistencies in definitions of measurement in different countries
- Improve global transparency
- Establish consistencies in global property measurement
Which IPMS standards are adopted by RICS?
IPMS for offices and residential
IPMS for industrial and retail drafted in 2018 and 2019 respectively and may be introduced in 3rd edition of RICS Property Measurement
What is dual reporting ?
Measuring to both RICS Property Measurement and RICS Code of Measuring Practice
E.g IPMS 3 and NIA
When would you use dual reporting?
When requested by a Client or if needed as comparables in valuation for properties measured to NIA only.
