Measurement Flashcards

1
Q

Tell me about different techniques and equipment used for data capture, their limitations and the calibration required

A 
Laser measure 
o	Accurate (to 1mm) 
o	Easy to use  
o	Difficult to use in sunlight  
o	 Calibration via regular checks of a known measurement. Manual calibration (Measure distance with ISO certified tape measure/ruler. Take 10 measurements with laser measure. Calculate standard deviation of the measurements, then input to disto) Or send to manufacturer.  
Tape measure  
o	No calibration needed  
o	Easy to use outside  
o	Less accurate then laser  
o	Difficult to use in some circumstances

Q

Tell me about RICS Code of Measuring Practice 6th edition, May 2015

A
  • The purpose of the Code is to provide succinct, precise definitions to permit the accurate measurement of buildings and land, the calculation of the sizes and the description or specification of land and buildings on a common and consistent basis.
17
Q

Comparing IMPS1 with GEA

A

Deduct the areas of:
• external open balcony
• generally accessible rooftop terraces

18
Q

A

• the inside finished surface comprising more than 50% of the floor to ceiling height for each IDF wall section

19
Q

Tell me about accuracy required for different applications, potential sources of error and how to reduce errors

A
  • +/- 25mm – accuracy - from PS
20
Q

Sydenham Road CR0 What recommendations did you provide regarding use of IPMS?

A
  • I recommended that the use of IMPS is to improve consistency across the industry and that by using IMPS measurements for comparables are likely to be more accurate
21
Q

Sydenham Road CR0 How did you calculate the reinstatement value?

A
  • Used the BCIS online portal
  • Establish the property information
  • Inputed floor area etc
22
Q

Sydenham Road CR0 Talk me through your GEA measurement.

A
  • Measurements taken to the external walls

- And to the party wall centre line

23
Q

Marlpit Lane CR5 Talk me through your use of scaled drawings.

A
  • Used a scaled ruler with the scaled drawings
  • I assessed the scale was utilised
  • Took measurements which I then multiplied by the scale amount
  • Cross referenced them to the supplied floor areas
24
Q

Marlpit Lane CR5 How did you cross-reference with marketing information?

A
  • The marketing information provided a floor area figure
  • This was in GIA
  • I compared this to my calculated GIA figure
25
Q

Marlpit Lane CR5 What were the limitations of your methodology?

A
  • Based off the drawings
  • Not measured in person
  • Based on the assumption that the property would be built to the drawings spec
26
Q

Marlpit Lane CR5 How did you report on the potential for inaccuracy?

A
  • Noted in the valuation report the measurements were taken from drawings and the property had not been inspected
27

Q

What is component area

A

One of the main elements into which the Floor Area of a Building can be divided.

Q

What scale was used?

A

1:100

30
Q

Difference bwteen 3A, 3B and 3C?

A

IPMS 3A - outer face of external wall and centre-line of shared walls
IPMS 3B - exclusive occupation
IPMS 3C - exclusive occupation excluding walls and columns

31
Q

What is a limited area under IPMS?

A

Limited areas include areas where there is limited amount of headspaces such as roof spaces

32
Q

What measurement information should be recorded under RICS Property Measurement 2nd Ed January 2018?

A 
Purpose instruction
Date of instruction
Date of measurement
Measurement standard adopted
If IPMS not used, reason
