When did IPMS/Property Measurement 2nd Edition take effect?
1st May 2018, issued in January 2018
What property does Property Measurement 2nd Edition cover?
Office and Residential
How would you measure a retail unit?
Using the reduced floor area principal (ITZA – In terms of Zone A) as per Code of Measuring Practice 6th Edition
For example – A shop unit measures 30m deep by 10m wide.
Zone A equates to the first 9.15m and has a weighting of 1 so (9.15 x 10) x 1 = 91.5sqm
Zone B equates to the next 9.15m and has a weighting of 0.5 so (9.15 x 10) x 0.5 = 45.75sqm
In this example the remaining 11.7m are back of shop storage and carries a weighting of 0.1 so (11.7 x 10) x 0.1 = 11.7sqm.
So although the shop has a Net Internal Area of 300sqm, the Reduced Floor Area (ITZA) is 148.95sqm (91.5+45.75+11.7)
How would you measure an office?
Using Property Measurement 2nd Edition – IPMS 2 (Broadly corresponds to GIA)
How would you measure a plot of land?
- OS Map software such as ProMap
- Measuring Wheel
How does a distometer work?
It bounces a laser of a target and measures how long it takes for the laser to return.
How would you measure odd shaped dwellings i.e. turrets, strange angles?
Circles = Pi x r2 , Triangles = Pythagoras theorem
What measurements would you take for the EPC of a property?
- Gross Internal Area
- External walls
- Unheated corridor
- Ceiling heights
- Insulation depth
- Glazing thickness
- Party walls
- Wall thickness
How did you measure the wall thickness?
A tape measure at a reveal i.e. window or door
How do you calculate the external area when measuring internally?
As a rule of thumb a multiplier can be used e.g. 1.5x for cavity construction or 1.2x for solid stone construction.
What have you measured recently?
- A flat that had a recessed balcony. I measured according to IPMS 3B – balcony area was included but stated separately.
- An end-terraced house with a garage. I measured according to IPMS 3B – Garage area was included but stated separately.
