Q

What is IPMS 3A?

A
  • Similar to IPMS 1, but for more precise buildings
  • Measure to the outer face of the external wall and to the centre line of shared walls

(Think of a flat and that has neighbours on both sides i.e. doesn’t own all her walls as shares them with the neighbours).

Q

What is GIA?

A

Whole enclosed area of a building within the external walls taking each floor into account and excluding the thickness of the external walls

The whole area of a building measured to the internal face of the perimeter walls at each floor level

(examples of where used: estate agency & valuation of industrial/warehouses)
approx. 2-3% deduction from GEA

23
Q

What is GEA?

A

The area of a building measured externally at each floor level

24
Q

What is NIA?

A

Is the usable area within a building measured to the internal face of the perimeter walls at each floor level
(examples of where used: shops)
approx. 15% deduction from GEA

25
Q

What does GIA include/exclude?

A

Include:
- Areas occupied by internal walls and partitions

  • Areas with a headroom of less than 1.5m

Exclude:

  • External open-sided balconies, covered ways and
    fire escapes
  • Canopies
  • Voids over or under structural, raked or stepped
    floors
  • Greenhouses, garden stores, fuel stores, and the
    like in residential property
26
Q

A

It came into effect on 1st May 2018

27
Q

How do you calibrate your laser distometer? CHECK

A

Send it off the manufacturers annually to be calibrated

28
Q

Why is calibration for laser distometers important?

A

To ensure accuracy

29
Q

What can you do to ensure that your measurements are as accurate as possible?

A
  • Taking several check measurements
  • Ensuring the laser or tape is measuring from the correct
    surfaces
  • Checking measurements with scaled plans or reliable mapping
    software
30
Q

What are the benefits and limitations of a laser distometer?

A

Benefits:
- Accuracy
- Ease of use

Limitations:
- It does not function well in bright light
- Difficult to use in very narrow spaces

31
Q

What is 1 acre in hectares?

A

0.4046

(one hectare contains about 2.47 acres)

32
Q

How would you measure a property of an irregular floorplate?

(Submission)

A

Using Trigonometry

33
Q

What is the purpose of a letter of reliance when using another party’s measurements?

A

CHECK

A

IPMS 1 - External Measurement
IPMS 2 - Internal Measurement
IPMS 3.1 External exclusive use
IPMS 3.2 Internal exclusive use

IPMS 4.2 Selected areas excluding internal walls

35
Q

What is the main difference in measurements of IPMS and GIA?

(Submission)

A

IDF v wall

36
Q

When would a valuer use a GEA measurement?

(Submission)

A

Insurance purposes

37
Q

Can you tell me what you understand of margins of error in measurement?

(Submission)

A

It is up to the valuer’s discretion to decide

38
Q

As per the RICS Measured survey recommends a tolerance of +/3 %

A
39
Q

How do you identify which is the internal dominant face?

(Submission)

A

The finished surface that occupies over 50% of the wall section

40
Q

What is the finished surface?
(submission)

A

The wall surface directly above the horizontal wall–floor junction, ignoring skirting boards, cable trunking, heating and cooling units and pipework.

41
Q

What is the internal dominant face?

A

The inside finished surface that occupies over 50% of the wall section

The internal finish comprising more than 50% of the floor to ceiling height for each wall Section.

42
Q

How does the Code of Measuring Practice differ from IPMS?

(Submission)

A

The main difference between the IPMS and the CoMP is that the measurements are taken to the “Internal Dominant Face”

43
Q

What would you do if Promap was unavailable if you were measuring a site of land?

A

A trundle wheel could also be used on site

44
Q

Why did you use IPMS2 in Briardale Gardens?

A

IPMS 2 is the interior area of the building + sum of all floors

Briardale Gardens was under one ownernship therefore, IPMS 2 most appropriate one

45
Q

What did you measure Grosvenor Waterside to?

A

GIA/IPMS 3B

46
Q

Is there anything you would include in IPMS 2 but would exclude in GIA?

A

Balconies, often referred to as external open-sided balconies.

  • IPMS 2 = Included but stated separately
  • GIA = Excluded

Accessible rooftop terraces

  • IPMS 2 = Included but stated separately
  • GIA = Excluded
47
Q

What about if you had a property that was extended into the loft space and was eaves affected? How would you measure? Ceiling heights

A

I would include areas with a headroom of less than 1.5m in GIA included in measurement but stated as seprate measurement in the report

But, for IPMS, I understand that these areas need to be stated separtely and therefore, would need to figure that the area of the room that falls underneath 1.5m height.

Methodology:

Room measurement first

Widest width x longest length

Then measure the area of the room below 1.5m

Area of widest part - area below 1.5m = area of loft space

48
Q

What is a typical scale for a floorplan?

A

1:50/ 1:100

Typically

49
Q

What is the scale of a location plan?

A

1:1250

50
Q

What is included and excluded in IPMS 2?

A

Measurements included but stated separately:
- Covered galleries
- Balconies (being external to the main structure of the
building)
- Generally accessible rooftop terraces.

Exclusions:
- Open light wells
- Upper level voids of an atrium
- External car parking

51
Q

What is included and excluded in IPMS 3B?

A

Measurements included but stated separately and
individually:
- Attics, basements/cellars
- Balconies and verandas in exclusive use
- Garages
- Limited use areas.
Measurements excluded but which may be stated
separately and individually:
- Patios
- Unenclosed parking areas, which may be measured
or defined by number of spaces
- Staircase openings

52
Q

If you were at a property and done all your measurements, when you came back to the office your measurements realised that you had missed a couple of dimensions, what would you do?

A

Use a scale ruler and scale a scaled floor plan

53
Q

If you didn’t have the floorplans avaliable, how could you measure?

A

You would have to rearrange to reinspect the property
