Measurement Rules (8)
The area measured is the surface area of the floor slab. No deduction is to be made for beams that form an integral part 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.
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, service floors, walkways, internal bridges, external links and roofs to internal buildings should be shown separately.
Sloping surfaces to be measured flat on plan.
The length of linear components measured is their extreme length. Curved work is to be described and identified separately.
Work to existing buildings is to be described and identified separately.
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 (8)
Concrete suspended floors, including: upper floors; podium slabs forming roofs to basements; transfer structures; balconies (internal and external) that are an integral part of the suspended floor construction; mezzanine floors; service floors, etc.; galleries, tiered terraces, etc.; walkways, internal bridges, etc.; external corridors/bridges forming links between buildings, including supporting frames; beams that form an integral part of the floor in framed buildings; floor beams in unframed buildings; roofs to internal buildings, where an integral part of the upper floor construction.
Reinforced concrete floors, including solid, waffle and trough slabs. Including all concrete, reinforcement (including punching shear reinforcement) and formwork (to soffits, edges and openings).
Post-tensioned concrete floors, including concrete, reinforcement (i.e. stressing cables, formwork, applying stressing and grouting up).
Worked finishes (i.e. in situ surface treatments), including tamped finish, power float finish and the application of surface hardeners.
Permanent formwork, including profiled sheet metal decking.
Designed joints.
Sundry items.
Where works are to be carried out by a subcontractor, the subcontractor’s preliminaries, design fees, risk allowance, overheads and profit, with allowance for these to be made within unit rate applied to element or component.
