GUIDE NOTES (Not Part of Contract Document)
Using TfNSW 3221
TfNSW 3221 is a QA specification and the use of QA specifications requires the implementation of a
quality management system by the Contractor that meets the quality management system requirements
specified in TfNSW Q. To comply with the intention of government policy as well as TfNSW 3221,
Roller Compacted Concrete works constructed using TfNSW 3221 require adequate surveillance and
audit by the Principal.
Technical Reference Notes
The following notes are intended to provide guidance on the application of this Specification. They do
not form part of the Contract.
Clause 1: General
This Specification requires the Principal to nominate the grade of roller compacted concrete. There is
no default grade for a project and further advice is found below.
Clause 3.2: Compressive Strength
This Specification provides for three standard grades of roller compacted concrete to be specified,
based on a minimum 28-day compressive strength. It is envisaged that one of these three grades
would be selected for the subbase layer. Selection of the mix grade will take into consideration the
time constraints for trafficking of the base layer after construction, as detailed in Clause 4.12.3 of
Specification TfNSW R90.
Clause 3.3: Compactibility Index
The Supplier must nominate the Compactibility Index for the mix, which should be in the range of 60
If the Supplier can establish the properties from another trial mix independent of this work and can
demonstrate that the roller compacted concrete has been produced in a homogenous manner and meets
the requirements of this Specification, a trial mix for the work under this Contract may not be
required.
Annexure 3221/A: Details of Work
The Principal nominates in this Annexure the grade required for the mix.
The Supplier nominates the Compactibility Index.
Annexure 3221/L: Minimum Frequency of Testing
Where the Supplier can demonstrate good and consistent process control, the Principal may consider
reducing the frequency of testing.
iii
Appendix A
For a contract where the order to the Supplier is placed directly by the Transport for NSW, the
requirements of Appendix A apply. The Principal has to nominate appropriate amounts for deductions
by way of liquidated damages for late delivery.
In determining the deductions for late delivery, the Principal should take into consideration the costs
related to the size of the crew, plant used for the job and the inconvenience for waiting. The
maximum amount per day should be based on the length of a normal working day.
