A review of techniques used in industry showed that there is an absence of a formalised, systematic approach to earthworks planning. The techniques used tend to be subjective and time consuming with a heavy reliance given to the experience and knowledge of the planner. This absence of a formalised technique can lead to inaccurate planning and makes explanation of the techniques difficult. This paper describes the development of a new automated approach for use by the planners to generate earthworks activities that overcomes such limitations. As well as creating activity sets in a much shorter time, the ability to compare various sets allows the planner more scope when planning earthworks. The model is able to generate activity sets that are comparable to those generated by a project planner.

The purpose of this paper is to investigate the innovative approaches to further reduce the environmental impacts during the construction of mega transportation infrastructure, particularly for Australia.

As part of this research, the Sydney Metro was exploited as a case study. This included reviewing the elements of reducing the environmental impacts for the Sydney Metro.

This research has found that there are six elements of reducing the environmental impacts of the Australian public transport infrastructure process. Moreover, this research also found that for the Sydney Metro, first, the logistic planning and optimisation was carefully developed followed by the remaining five elements.

The originality of this research consists of carefully examining the Sydney Metro’s environmental implications including its on-going EIA and EPA compliance.
