Measurement Flashcards
(26 cards)
When undertaking a measured survey, what equipment have you used?
Laser Distance Measurer, Tape Measure or Measuring Wheel.
For measured surveys included external areas, what equipment could you use?
I don’t have experience using them but a Total Station or 3D Laser Scanner.
How do you ensure a disto is accurate prior to a survey?
Check the disto for any dirt or damage, calibrate the disto and then perform several known distance checks using provided floorplans or measure with a tape measure first.
When might you use a laser distance measurer?
For quick and accurate measurement of distances, especially in situations where a tape measure is impractical like measuring ceiling heights.
When might you use a trundle wheel?
For quick estimates of longer distances (less accurate than lasers or total stations).
When would you use Vernier Callipers?
When you need accurate measurements of small or intricate objects.
What does IPMS stand for?
IPMS stands for International Property Measurement Standards.
What RICS guidance is available for measurement?
RICS Property Measurement professional standard and RICS Code of Measuring Practice professional standard
What situations does IPMS, Property Measurement and Code of Measuring Practice apply to?
IPMS applies to offices and residential buildings
Property Measurement applies to offices and residential buildings
Code of measuring practice applies to all other building types
What is the internal dominant face?
The internal dominant face is the main internal surface used for measurement and is a surface which forms more than 50% of the vertical wall area.
According to the Code of measuring practice, what is the GIA?
Gross internal area which is similar to IPMS 2 is Gross Internal Area is the area of a building measured to the internal face of the perimeter walls at each floor level. Excludes external projections.
According to the Code of measuring practice, what is the GEA?
Gross External Area which is similar to IPMS 1 is the area of a building measured externally at each floor level. It excludes open sided balconies, carparks or roof terraces.
According to the Code of measuring practice, what is the NIA?
Net Internal Area which is similar to IPMS 3 is Net Internal Area is the usable area within a building measured to the internal face of the perimeter walls at each floor level. Excludes entrance halls, toilets, cleaning cupboards.
According to Property Measurement Standards, what is IPMS 1?
According to Property Measurement Standards, what is IPMS 2?
According to Property Measurement Standards, what is IPMS 3?
Why is it important to take a consistent approach towards measurement?
To ensure that the data captured is accurate, fair and can be relied upon for decision making.
Why did you use a tape measure to measure the length of the cracks to the boundary wall?
As the tape measure was more flexible and the crack was too long for callipers and there was no unobstructed path for a laser distance measurer to use.
Why did you use Vernier Callipers to measure the widths of the cracks to the boundary wall?
Because they have high accuracy when measuring small widths and the prongs of the callipers allow for butting up to the actual surfaces of the crack.
What BRE documentation did you use to categorise the cracks to the boundary wall?
BRE Digest 251.
Can you provide examples of some of the crack categories in BRE Digest 251?
Hairline cracks up to 0.1mm and fine cracks up to 1mm.
What’s a reinstatement cost assessment?
A assessment of the cost to completely rebuild or reinstate a property to its original condition if it were damaged or destroyed.
Explain the process of undertaking a reinstatement cost assessment?
I inspected the building with existing floorplans that the client had provided and took check measurements of the GIA of each floor in line with Code of Measuring Practice and RICS Reinstatement Cost Assessment of Buildings.
Why is accurate measurement so important when undertaking a reinstatement cost assessment?
Because it is the basis on which insurance companies will cover costs so if it is too little it will be detrimental to the building owner but if it’s too excessive then it’s detrimental to the insurance company.
