Measurement Rules (7)
The area measured is the surface area of the floor slab. No deduction is to be made for voids within the floor slab that are less than 1.00m2 in surface area.
Where more than one floor construction type is employed, the area measured for each floor construction type is measured separately.
Where more than one floor construction type is employed, the combined area of each floor construction type should equal the total area of the upper floors.
Areas for balconies, galleries, tiered terraces, walkways, internal bridges, external links and roofs to internal buildings should be shown separately.
Sloping surfaces to be measured flat on plan.
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, contractor-designed work is to be described and identified separately.
Note: i.e. not the entire building projectIncluded Items (15)
