Measurement Flashcards
Explain the:
GN Code of Measuring Practice 2015
PS Property Measurement 2018
How would you describe NIA
Net Internal Area
net effective area that you would measure in a building
NIA is used for certain asset classes wrt valuation (as opposed to construction)
How would you describe GIA
GIA is used for all asset classes for construction
GEA
GEA
Explain zoning
A valuation technique which considers the front side of the retail unit to be more valuable than parts at the back
(show examples of zoning)
Office content within a warehouse building
Generally 10%
Under GIA, how do you deal with a mezzanine?
If it’s got permanent access, you include it in GIA
If it’s got a rope access or a lean to, you do not include it
What are the typical measurements to take in an industrial unit?
- Size of loading doors
- eaves height
- floor loading capacity
Explain IPMS
IPMS mandatory currently to resi and office
Benefits of IPMS: produce consistency of comparing assets around the world
Key features of measuring office unit to IPMS?
IPMS 3 is MANDATORY to record it
If client doesnt want it, you don’t have to include it in report BUT you have to
Internal dominant face (face that occupies 50% of that wall area)
Particularities of IMPS in multi let floor?
Key features of measuring office unit to IPMS?
IPMS 3 is MANDATORY to record it
If client doesn’t want it, you don’t have to include it in report BUT you have to have measured it + promote the benefits of it to client
Internal dominant face (face that occupies 50% of that wall area)
IMPS All Buildings 2023
Will lead to a new Property Measurement PS to make mandatory IMPS for all asset classes
What are the tools of measurement
- Laser
- Measuring tape
- Trundle wheels (as a check post measuring on website)
How do you ensure your laser measurer is calibrated?
You measure a known distance
What is the tolerance for measurement distance?
What is the equivalent of IPMS to UK standards, for office?
- IPMS 1, which equates closely to the former GEA. Measures the area of a building including external walls (used for planning purposes or the summary costing of development proposals).
- IPMS 2 – Office, which equates closely to the former GIA.
Measures the interior area e.g. excludes open-light wells and external car parking
Differences: balconies, rooftop terraces are included in IPMS2 but stated separately (excluded in GIA) - IPMS 3 – Office, which equates somewhat to the
former NIA (net internal area).
Measures the occupation of floor areas in exclusive use. Useful for agents and occupiers, facility managers, property managers, etc
What do you know about IPMS 3?
As stated in P/S Property Measurement 2018
IPMS 3 (Office) equates to former NIA
- It measures the occupation of floor areas in exclusive use. Useful for agents and occupiers, facility managers, property managers, etc
- All internal walls and columns within an occupant’s exclusive area are included within IPMS3. The floor area is taken to the internal dominant face and, where there is a common wall with an adjacent tenant, to the centre-line of the common wall.
- Balconies, covered galleries, and roof top terraces in exclusive use are to be measured to their inner face and their areas stated separately.
What is ITZA
ITZA = ‘area in terms of Zone A’.
‘Zoning’ is a measuring methodology for comparing shops of different sizes and layouts.
Each zone is usually 6m deep.
What basis of measurement do you use to measure Build Costs
GEA
What is different between IPMS 3 and NIA
IPMS3:
Measures to internal dominant face of the wall
Includes columns and areas under 1.5m ceiling height
Goes to glazing if window is >50% of ceiling height
Includes external areas in exclusive use such as balconies, roof terraces
Goes to middle of partition on wall between two users
NIA:
Includes areas covered by skirting board
Goes to glazing if window is in full height
