Measurement Rules (7)
Where components are to be enumerated, the number of components is to be stated.
The length of linear components measured is their extreme length, over all branches, fittings, etc.
Other cost-significant components are to be described and identified separately. Such components are to be measured by area (m2) or linear measurement (m), or enumerated (nr) separately in accordance with the rules of measurement for this sub-element.
Descriptions should include the amount of any PC sum included in the unit rates applied to the item
Work outside the curtilage of the site 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.
