Minimbah Bank Third Track

Location: 
Central Coast, NSW
Total Project Value: 
>$100M

This project involved the construction of approximately 10kms of third rail track from Minimbah to Whittingham to improve reliability and capacity of the Hunter Valley Rail Network to Newcastle.

MIEngineers was engaged by GHD to develop a detailed probabilistic (Monte Carlo) risk based cost estimate using appropriate risk software. This project was originally to be undertaken as a construct only project; however the client sought to change the delivery to an Alliance Model.

MIEngineers also organised, facilitated and documented value engineering, risk and cost estimate workshops with appropriate project team members. With the aid of MIEngineers’ expertise, Australian Rail Track Corporation Ltd (ARTC) was able to successfully achieve the required outcomes to the satisfaction of all parties. 

MIEngineers was subsequently contracted as an Independent Estimator to provide an independent review of cost reforecast. The procedure adopted for this was to undertake a high level review of the supplied information in order to select the cost centres that were key contributors to an overall increase in project cost. In particular, the review focused on:

  • Major new items not previously included in the Target Outturn Cost (TOC) estimate;
  • Cost centres where there was a substantial increase from the TOC estimate;
  • Key individual items indicating a substantial increase in either quantity or rate;
  • Risk and Opportunity; and
  • Escalation.
