Q

How do you calibrate a laser measurer (disto)?

A
  • Establish a constand baseline → easy to access / not long in length. → measure with accurate steel rule
  • Place disto on tripod or flat/secure surface and take the measurement from baseline at least 10 times
  • Average the values measured and calculate the standard deviation

Reference RICS Property Measurement, 2018 and measure on NIA and IPMS 3

93

94

Consult Property Measurement and Code of Measuring

95
Q

What is Quantum?

A

Allowance for quantity for large properties

→ Dependent on demand for particular type and size of property in areas

96

→ Measurement of full height glazing

→ Leisure is special use and defined seperately (using GIA)

106
Q

WHat does RICS say about using m or ft for measuring?

A

Adopt metric units as standard

→ if Client requires imperial uits, they can be provided as supplemental information

107
Q

A

Measure from the main frontage, then apply an additional % to the Zone A space

108
Q

What issues might you come accross when measuring period buildings?

Fireplaces → viewed same way as heating apparatus. Exclude if protruding 0.25m into usable space

Mansard roof - a lot of space and under 1.5m

Having to exclude any unuseable circulation space
