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.
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.
