Measurement Rules
Included Items
Excluded Items
Measurement Rules (5)
The area measured is the area serviced by the system (i.e. the area of the rooms and circulation spaces that are served by the system, which is not necessarily the total GIFA of the building). The area serviced is measured using the rules of measurement for ascertaining the GIFA.
Where more than one system is employed, the area measured for each system is the area serviced by the system.
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.
