3.7.        CONCRETE WORKS
General
This specification sections applies for insitu-concrete and pre-cast concrete elements.

All components of concrete works such as concrete mix, water-cement ratio, concrete strength, pigment
quantities, formwork types, release agent, sand type and sealer shall be kept consistent throughout the
project to avoid differences between the elements.

Regulatory Standards & Industry Association Reference Publications
The relevant Industry Association reference publications and guide standards should be use for the relevant
work:

•   CCAA Cement Concrete & Aggregates Australia www.concrete.net.au
•   CCAA Guides series, including the following as applicable:
•   CCAA T57 Guide to Off-Form Concrete Finishes
•   CCAA T59 Guide to Concrete Flatwork Finishes
•   CCAA Data Sheets series, including the following as applicable:
•   CCAA Data Sheet – Avoiding Surface Imperfections in Concrete
•   CCAA Data Sheet – Removing Stains from Concrete
•   CCAA Data Sheet – Cleaning Concrete
•   NPCAA - Precast Concrete Handbook
•   AS 3610 – Formwork for Concrete
•   AS 3600 – Concrete Structures
•   AS 1379 – Specification and Supply of Concrete
•   Local Authorities Applicable Regulations
•   Building Code of Australia including Standards referenced in the NCC/BCA.

Shop drawings
Formwork drawings and documentation are to be prepared by the nominated subcontractor that show the
arrangement of panels, joints, bolt, tie-rid holes and similar visible elements in the formed surface, form
linings, form coatings, and where applicable the reuse of formwork and shall be submitted for approval.
Approval for Formwork pattern is to be gained from Landscape Architect prior to the commencement of
works.

Ensure tie-rod hole locations are uniform. Ensure all capping have a fall inwards. Consider junction details
that avoid poor weathering performance.

Test panels
Cast the panels using the formwork, concrete, colour, compaction equipment, form release agents, curing
and formwork removal methods, which are to be used in the final work. Supply sample panels to AS 3610 for
the application specified. Test panels to be approved in written by the Landscape Architect before starting
any works.

If test panels are approved those serve as a reference for all future works. Test panels to remain as an off-
form finish until all works is done. Protect test panel to make sure no adjacent material can stain. Approved
test panel may be integrated into the final work.
