Measurement Rules (8)
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 obstructions.
Where more than one type of component is employed, each component is measured.
Other cost-significant components to be described and identified separately. Such components are to be measured by area (m2) or linear measurement (m), or enumerated (nr) separately.
Curved work is to be described and identified separately.
Work to existing buildings 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 rainwater drainage installation. A single combined percentage addition can be applied to cover the costs of both testing and commissioning.
Contractor-designed work is to be described and identified separately.
Note: Where the contractor is only responsible for designing specific elements and/or components of the building project (i.e. not the entire building project).Included Items (11)
