1.2 Design Objectives

Type of Road installation e.g CHR treatment

What is the design trying to treat/remedy?

1.3 Safety In Design

Safety in Design has been considered in accordance with the WHS Act 2012 (Code of Practice “Safe Design of Structures”).

DPTI has the primary duty under the WHS Act to ensure, so far as is reasonably practicable, that workers and other persons are not exposed to health and safety risks arising from the design of new infrastructure. Safe design is the integration of control measures early in the design process to eliminate or, if this is not reasonably practicable, minimise risks to health and safety throughout the life (Construction, Maintenance, Demolition) of the infrastructure being designed.

Safety in Design assessments undertaken during the design development stage of the project has included consideration of the safety issues that might face the constructors, the users (that is, the motoring public and all other road users) and maintenance worker. Location of documentation:

https://www.dpti.sa.gov.au/standards/safety_in_design_guidelines

The development and management of the design must be integrated with the Safety in Design detailed in Part PC-EDM2 Safety Management in Design.

List any matters that have been addressed during the design as per table 1:

XXXXXXXXX Aconex/Teambinder/Knet reference Issued to DPTI/Approved?


Roads Design Report

The Austroads Guide to Road design provides NDD (normal design domain). The use of design parameters outside NDD is classified as a design departure and requires approval by the Engineering Authority for the Commissioner of Highways

The EDD/ design departures guideline should be also read in conjunction with Brownfield/Greenfield Austroads Supplement Guide

The EDD / design departure procedure / supplement guide are located:

https://www.dpti.sa.gov.au/standards/road_design_outputs

7. Safe System Assessment Safe System Assessment is a tool that has been developed to provide a measure of the extent to

which a road infrastructure project aligns with Safe System principles and the ultimate objective of eliminating fatal and serious injuries from crashes on the road network. DPTI has developed guidelines which specify when a Safe System Assessment should be conducted and to provide guidance on the assessment process. The DPTI safe system guidelines should be used in conjunction with Austroads ‘Safe System Assessment Framework’.

The DPTI guide and assessment is located in the link below. The assessment will be required for all projects (except SSA’s are optional for projects under <$2M but requires documentation of how the project has considered safe system principles.)
