Hi Sam,just quick one....when a QS calculate the area for a building roofing,does he take into the account of the pitch effect. In one of my project, we have discovered that the pitch degree of 32 has significant variance toward the roofing area and simple calcultion shows that its not included and when highlighted to the project QS, we where told that its deem inclusive in our rates for the pitch effect....your valuable advice on this,thank you.

According to the Standard Method of Measurement (SMM - Section A.3/2 & L2/1), most roofing is measured according to net finished area, ie net roof sheet area as per pitch, not flat on plan.


It is possible to deviate / depart from the standard way of doing things - ie use our own method - so long as it is indicated / made known how the measurement departs from the standard method.  If the project QS said that the pitch effect is deemed inclusive in the rates - it is possible.  Check with the QS where it said so to this effect in the contract document or SMM.
