Measurement Flashcards
Tell me about your understanding of RICS Property Measurement.
RICS Property Measurement is a professional statement which reflects the IPMS standards and includes the application of the IPMS in practice , technical definitions and IPMS for residential and office buildings.
When would you use NIA as a measurement basis?
Agency and valuation – a basis of measurement for valuation,
market analysis and marketing of offices for rental and capital valuation.
Property and facilities management – a basis of measurement for calculating service charges in mixed-use buildings for the apportionment of occupiers’ liability.
When would you use GIA as a measurement basis?
Costings – a method of measurement for a basis of calculating building costs and reinstatement costs.
When would you use GEA as a measurement basis?
Planning – basis of measurement for planning applications and approvals, site coverage, etc.
Tell me about what is included in NIA/GIA/GEA?
NIA includes kitchens, notional lift lobbies and fire corridors, area occupied by demountable partitioning
GIA includes columns, lift wells, mezzanines with permanent access, loading bays, ancillary office
GEA includes external walls, measures around outside of building
What measurement basis would you use for office property?
For planning purposes I would use IPMS 1 (universal)
For basis of calculating building costs and reinstatement costs I would use IPMS 2
For agency, valuation, taxation or property management I would use IPMS 3
What measurement basis would you use for retail property?
IPMS 1 – External - typically used for planning purposes
IPMS 2 – Retail (Internal) – typically used for providing data on the use of space or for benchmarking
IPMS 3A, B and C – Retail (Occupier) – typically used for transactional and cost allocation purposes
What measurement basis would you use for industrial property?
IPMS 1 – External – typically used for planning purposes
IPMS 2 – Industrial (Internal) – typically used for providing data on the use of space or for benchmarking
IPMS 3A – Industrial (External: Exclusive Occupation) and IPMS 3B – Industrial (Internal: Exclusive Occupation) – typically used for sale and leasing purposes
How does RICS Property Measurement differ from the old Code of Measuring Practice?
RICS Property Measurement incorporates IPMS measurement of office and residential buildings.
Why is accuracy important when you measure buildings?
Basis for comparison
Consistency and accuracy
Usable space - service charge
How do you calibrate a laser measurer?
LEICA guidance:
establish a constant baseline (with an accurate steel tape)
take at least 10 measurements from a fixed point
average the measured values to determine systematic deviation from the baseline
calculate standard deviation
calculate the typical accuracy by adding systematic deviation to double of standard deviation
Why do you take check measurements?
to ensure consistency with the floor plans
What is a potential source of error when measuring?
Lasers do not work well in bright sunlight, as it can be hard to see the laser beam. Using a long tape measure can overcome the issue or by shadowing the target area
When using a laser to measure to a dark surface, the measuring time can increase leading to inaccurate measurements. Taking a sheet of A4 white paper to site can be used as a measuring target
Steel tape measures may not be long enough for certain distances
Measuring software may be less accurate given that it is hard to pinpoint the exact boundaries or surfaces to measure to online
What is IPMS?
International Property Measurement Standards - coalition of over 80 professional organizations that publish standards on office, residential, industrial, retail and all building classes measurement
Why has IPMS been introduced?
to ensure that property assets are measured in a consistent way, creating a more transparent marketplace, greater public trust, stronger investor confidence, and increased market stability.
