A

Gross External Area is the area of a building measured externally at each floor level.

46
Q

A

Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor level

48
Q

Tell me about how you use floor plans to facilitate measuring buildings?

A
  • I use floorplans to sketch my measurements

- I use floorplans to check my measurements once I have calculated – any discrepancies I go back and remeasure.

49
Q

Why do you take check measurements?

A

To ensure accuracy before reporting

50
Q

Tell me about a strength and weakness of a measuring technique you have used.

A

Laser measure – fast, usually very accurate.
Disadvantage: sometimes laser will not reach wall to wall, or you are not able to see it – need to have something held up at half way to combat.

51
Q

When would you use a tape measure?

A

For narrow areas

52
Q

What is a potential source of error when measuring (3)?

A
  • Human error – misreading, additional check measurements.
  • Knowledge error (unsure what to in/exclude) - take enough measurements to calculate later on
  • Equipment error – faulty equipment which should be checked and calibrated quickly/annually.
53
Q

What would you use IPMS 3B and not IPMS 2?

A

Because I was measuring the area in exclusive occupation.

54
Q

What is Effective Floor Area?

A

Effective floor area is a measurement basis historically used by the UK Valuation Office Agency for measuring flats (but not houses) for council tax.

55
Q

What is ‘area’ is EFA? What would you take off to convert from IPMS 3C to EFA (3)?

A

EFA is ‘useable area’ or ‘carpet area’

  • Areas with headroom of less than 1.5m
  • Bathrooms, showers and toilets
  • The area of balconies
  • The area of roof terraces
56
Q

What are limited use areas and how do you report these?

A

In certain markets there may be areas in buildings that are incapable of legal or effective occupation due to local or national legislation.
Such areas and their limitations are to be identified, measured and stated separately within IPMS reported areas.

57
Q

How would you measure a mezzanine?

A
  • Included in GEA and GIA (if permanent access)
  • Not included IPMS 1, 2,3 or NIA
  • Resi – included in IPMS
58
Q

Where is the measurement taken to for the common wall when measured for IPMS 3?

A

Centre line of the common wall

59
Q

Where is the measurement taken to for the common wall when measured for NIA?

A

Surface of the common wall

60
Q

What is the difference between IPMS 1 and GEA (3, 1 stated separately)?

A
  • Covered galleries (internal balconies) – included but stated separately (Included GEA)
  • External open sides balconies included but stated separately (excluded GEA)
  • Accessible roof terraces - included but may be stated separately (normally excluded GEA)
61
Q

Why is accuracy important when you measure buildings (3, 1 in certain circumstances)?

A
  • It can have a significant influence on value
  • It is important to measure accurately to ensure you have met client’s requirements
  • It is important to measure accurately so the fit out can be implemented correctly
62
Q

What are the changes between the existing and new (IPMS) residential practice?

A

Replaces use of GEA/GIA/NIA in code of measuring practice.

63
Q

What is the definition of GIA (resi)?

A

Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level

64
Q

Residential - What’s the difference between GIA and IPMS 3B (4)?

A
  • Measured to IDF as opposed to surface wall.
  • Areas occupied by the reveals on windows if assessed as IDF included
  • Balconies – Included but stated separately
  • Accessible roof terraces included but stated separately
65
Q

How do you deal with tenant’s improvements when measuring for valuation purposes?

A

This would depend on the terms within the lease and whether they are to be disregarded or included.

66
Q

What are the current IPMS industrial and retail trajectories?

A
  • IPMS Industrial – we believe early 2020 implementation
  • IPMS Retail – we believe early 2020 imp., RICS has not incorporated retail/industrial yet CHECK AGAINST EXISTING QUESTIONS
67
Q

What are the limitations of lasers in bright light and darkness, and what should you therefore do in each case?

A

o Lasers do not work well in bright sunlight - use a long tape measure to overcome issue or by shadowing target area.
o 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.

68
Q

When can cloth tape be inaccurate?

A

o Cloth tape can be inaccurate if not fully stretched or overstretched.

69
Q

Why can measuring software be inaccurate?

A

o Measuring software may be less accurate given it is hard to pinpoint the exact boundaries or surfaces to measure to online

70
Q

Why can photocopied plans be inaccurate, and how do you check this?

A

o Photocopied scaled plans can be distorted which will affect the scale of the plan- use check measurements to confirm scale accuracy.

71
Q

What are the 2 methods for laser calibration?

A

o Check typical accuracy by following the Leica guidance
 establish a constant baseline, taking at least 10 measurements from a fixed point and carrying out a number of calculations.
 Record result in a log.

o Or send disto for calibration –
 Typically lasers become inaccurate after being dropped and may show an error (e.g. 256).
