Measurement Rules (4)
Where components are to be enumerated, the number of components is to be stated.
Work to existing buildings is to be described and identified separately.
Where the contractor is only responsible for designing specific elements and/or components of the building project (i.e. not the entire building project), contractor-designed work is to be described and identified separately.
The percentage additions for testing and commissioning are to be applied to the total cost of the items comprising the sub-element. A single combined percentage addition can be applied to cover the costs of both testing and commissioning.
