Cronulla Rail Duplication Project

Location: 
Sutherland Shire, NSW
Total Project Value: 
$250M

This project involved the construction of a second rail line between Cronulla and Sutherland to enable an increase in peak rail services for commuters from four trains per hour to six, thereby reducing crowding on Cronulla Services. The project was technically challenging with construction taking place in a live rail environment. 

The project included: construction of 6.6km of new track, extended platforms and additional train stabling facilities; additional platform and easy access improvements; new cuttings, embankments and retaining walls to accommodate the additional track; upgrade of ten road and rail bridges along the route; and new signal works.

MIEngineers was engaged to develop our client’s construction tender program including allowance for the highly restricted rail possessions and implementing strategies for the mitigation of delays if these possessions were missed. 

To resolve this, MIEngineers developed a highly complex and involved construction program, undertook constructability reviews and “what if” analysis, and developed alternate strategies to reduce construction timing. In particular, this project required: analysis of designs for constructability, advising designers of outcomes and offering alternates; developing suitable construction methodologies and programming of these methods; program review and consideration of alternate methods, sequences and programs; detail and analyse risk assessments and manage these; manage, negotiate, consult and liaise with disparate stakeholders; and provide timely and appropriate communication and reporting, furnishing necessary information for decision makers and other stakeholders.

This demonstrates experience in programming for multidisciplinary rail infrastructure projects, and an understanding of those technical requirements and staging parameters. In particular, knowledge and skills in programming of civil works, structural, minor tunnels, existing, amended and new utilities, electrical, rail, rail systems, architecture and urban design, demanding construction staging requirements, fire and life safety, and rail & rail overbridges.

The result was a winning bid and a now successfully completed project.
