Measurement - Level 1 Flashcards
Tell me about your understanding of RICS Property Measurement.
RICS Professional Statement - Mandatory requirements for RICS Member and Firms.
1 Professional statement: property measurement (applies to all properties and includes IPMS measurements for office and residential buildings only).
2 RICS IPMS Data Standard.
When would you use NIA as a measurement basis?
NET INTERNAL AREA
IPMS 3 –
Office (formerly NIA) Agency and valuation – a basis of measurement for valuation, market analysis and marketing of offices for rental and capital
valuation.
Taxation – a basis of measurement for local taxation purposes, where applicable.
Property and facilities management – a basis of measurement for calculating, together with component areas within IPMS 2 – Office, service charges in mixed-use buildings for the apportionment of occupiers’ liability.
When would you use GIA as a measurement basis?
IPMS 2 – Office, which equates closely to the former
GIA (gross internal area).
IPMS 2 – Residential, which equates closely to the former GIA (gross internal area)
IPMS 3B – Residential, which equates somewhat to
the former GIA (gross internal area).
Building cost estimation – GIA is a recognised
method of measurement for calculating building costs
Basis of measurement for marketing and valuation of industrial and retail etc
Rating for warehousing, industrial, food stores etc (areas under 1.5m excluded)
Property management - calculation of service charge.
New homes Valuation - Valuation and marketing of residential dwellings.
When would you use GEA as a measurement basis?
Gross External Area is the area of a building measured externally at each floor level.
Would use for the following;
Building cost Estimation - residential for insurance purposes.
Can be used for town planning, planning applications
Rating and Council Tax (except areas with less than 1.5m, integral garages and attached structures of inferior quality - porches being excluded).
Tell me about what is included in NIA/GIA/GEA?
GEA - Gross External Area is the area of a building measured externally at each floor level.
NIA - Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor
level.
GIA - Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level
What measurement basis would you use for office property?
IPMS 2 – Office - Similar to GIA.
IPMS 3 – Office - Similar to NIA.
What measurement basis would you use for industrial property?
GIA or NIA (GEA used for industrial buildings in Scotland).
How does RICS Property Measurement differ from the old Code of Measuring Practice?
The old code was originally (prior to 2015) intended for UK use only. Became globally applicable in 2015, but different territories were using differently.
Why is accuracy important when you measure buildings?
Used as a basis for valuation, provision of reinstatement costs.
Accurate comparison of alternative properties in the market
- Personal decision making for property occupation (i.e. interior design, furnishing and refurbishment etc.)
- Confidence to rely on the measurement provided by someone competent to do so, using a consistent standard for property measurement.
Tell me about how you use floor plans to facilitate measuring buildings?
Use detailed drawings on new build sites where the property has yet to be built to measure the building.
How do you calibrate a laser measurer?
Class 1/2 steel tape with a roman stamp to establish a base measurement.
Take ten measurements and then calculate the standard deviation to assess accuracy. I do this using the calibration spreadsheet from the Leica Website.
Leica send calibration certificate with each disto.
Why do you take check measurements?
To confirm accuracy of readings.
When would you use a tape measure?
If disto readings not showing due to light external, reflective surfaces or dark backgrounds.
When would you use a trundle wheel?
Large measurements not suitable with tape or laser measurer. Acreage.
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
Lasers may be inaccurate when measuring to colourless liquids, glass, styrofoam, permeable or high gloss surfaces
Cloth tape measures can be inaccurate if not fully stretched or if they are over-stretched
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
Photocopied scaled plans can be distorted which will affect the scale of the plan. This can be overcome by using check measurements to confirm the accuracy of the scale specified on the plan
