posts; storage features.
Performance criteria
2.1
The set out for the feature ensures that formwork is located to form a feature as
defined in drawings or specifications.
2.2

2.4
Surface of formwork is treated to achieve the finish specified.
Range
2.5

they are located as specified in the finished concrete.
Range
2.6
treatments – lining material or formwork pattern, release agent,
retarder.
may include but is not limited to – bolts, lugs, ties, nailing strips,

3109:1997.
3.2
Ready mixed concrete delivered to the site is ordered to the site specification.
3.3
Surfaces of previously poured concrete are roughened to form bonding key and
are treated with cement slurry mixed to meet site specification to enhance
bonding of newly poured concrete.
3.4

formwork, displacement of reinforcing or fixings and inclusions, or deterioration
in the mixed quality of the concrete.
3.6
Hand or power tools selected for finishing of placed concrete are suitable for the
work, and are used in accordance with workplace procedures, without injury to
the operator or danger to others, in achieving the concrete finish detailed in the
site specification.
