Morning guys,
Linear meter, Square meter, Meter cube all relate to the same thing volume of scaffold to be paid for.
None of it is over complicated and none of it is new these three units of measurement were used in scaffolding long before I joined the industry.
Linear meter refers to the length of a completed lift of scaffold with boards:
Example: a 30m long by 5 lift access would be 30linear m times 5 lifts = 150 linear meters
Square meters refers to the 2 dimensions on an elevation Height x Width
Example: a 30m long by 10m high scaffold (same scaffold as above) would be 30 x 10 = 300Sq meter
Cubic meters, more commonly used in measurement of birdcages = Length x Width x Height.
I have seen this method used in the measurement of Independent’s although I am not sure why.
(An independent is in most cases a standard width to an individual scaffold company and as such the third dimension becomes redundant when valuing a scaffold)
When it comes to applying a price to the scaffold the rates should bring you to the same answer:
10m linear x 2 lifts of completed lift = 20 meter @ ₤15 per meter = ₤300
the equivalent price based on Sq m should = ₤300 / 10meter length / 4 m height= ₤7.5/mSq
and the equivalent Cubic meter rate for a 1.5 wide (5+1 Bd) scaffold would be
₤300 / 10 / 4 / 1.5 = ₤5 per cubic meter
Hence
Linear 10m x 2 lifts x ₤15 = ₤300
Sq m 10m x 2 lifts (4m) x ₤7.5 = ₤300
Cubic m 10m x 2 lifts (4m) x 1.5m) x ₤5 = ₤300
Hope this is of help
regards
Alan
