Measurement Flashcards
What are the main differences between IPMS3 and NIA?
I’m IPMS:
Measured to the internal dominant face
No exclusion of restricted height
Columns are included
Covered galleries/balconies/roof terraces included (stated separately)
Floors with multiple occupiers – measure to midpoint of partition wall
What might you use IPMS1 for?
This is the equivalent to GEA, so perhaps planning or to measure a size of a whole site.
What might you use IPMS 2 for?
This is the equivalent of GIA, so perhaps for calculating build costs.
What would you use IPMS 3 for?
This is the equivalent of NIA, so for agency or valuation purposes.
When measuring an industrial unit, on what basis do you measure?
What do you exclude from the measurement?
On a GIA basis.
I would exclude:
- Canopies
- Fire escapes
- Covered ways
How much do you measure it fitted shop unit?
On an NIA basis.
I would attempt to estimate the actual build with by:
– getting behind the partitioning
– removing a ceiling tile
– inspecting the basement or first floor
– using a scale plan
When might you use GEA?
For planning
For residential building cost estimates
For what reason might you use GIA?
Agency
Commercial build cost estimates
Valuation
For what purpose might you use NIA as a basis for measurement?
Agency
Valuation
Rating
