5 Appendix 44 Initial Project Training Management PlanAppendix 45 Industrial Relations Strategy7 SWTC Performance and design requirements (Section 5) Safety by Design Reference documents and Standards PavementsSafety by Design The Contractor must consider and address all safety issues and requirements relating to safety during construction, operation and maintenance in the development and production of the Design Documentation, including: ..8 Safety by design examples9 SWTC Performance and design requirements (Section )Reference documents and Standards The Project Works , Contractor s Work, and the Temporary Works must meet the requirements of RMS and AUSTROADS publications and relevant Australian Standards.

6 If suitable Australian Standards do not exist for the design of any element of the Contractor s Work, Project Works or the Temporary Works , the Contractor may use international standards that reflect world s best practice, subject to the written approval of RMS s Performance and design requirements (Section )Reference documents and Standards Unless otherwise expressly stated in the deed or the SWTC, the following order of precedence must apply .. specific provisions in the deed; publications; publications; Standards; Australia handbooks; reference documents and standards.

7 11 SWTC Performance and design requirements (Section ) Safety by Design Reference documents and Standards PavementsPavements must: incorporate drainage practices that maintain a constrained moisture regime which prevents significant variations in the capacity of the subbases and subgrades to support the pavements; accommodate movements of the subgrades associated with changes in moisture content (particularly near batters); accommodate settlements and deformations of the embankments and subgrades resulting from settlements of foundations; 12 SWTC Performance and design requirements (Section )Pavements must: deliver the performance levels for the wearing surfaces specified in Appendix 12 of this SWTC minimise spray in wet conditions; separate surface and subsurface drainage systems to avoid overloading subsurface systems; at all times conform to the surface flow requirements detailed in Appendix 10 of this SWTC.

8 And have wearing surfaces which produce noise levels and tonal noise characteristics that contribute to noise mitigation and compliance with the noise level requirements of the deed. 13 Low noise pavements (when required)> 80 km/hr - Use OGA or SMA 80 km/hr Can use DGA or light hessian drag for concreteLow noise surface must extend the full width of the structural pavement14 Minimum pavement thickness - flexibleMinimum subbase layers:- bound 170 mm- lean mix concrete 150 mmAsphalt:175 mm over bound subbase30 mm for OGAC onstruction tolerances covered in specification15 Minimum pavement thickness - concreteMinimum lean mix concrete subbase 150 mmBase - Table of SupplementConstruction tolerances as per specificationAdditional base thickness listed in requirements in SWTC16 Content What is the SWTC?
