North West Rail Link

Client: Transport for New South Wales – NWRL Project
Location: Greater Sydney Metropolitan Region
Duration: 2012 - 2015
Project Value: $8 billion
Roles: Various

The NWRL project will deliver a new high frequency single deck train system between Cudgegong Road, Rouse Hill and Chatswood. The Project includes eight new stations, 15.5 kilometres of tunnels from Epping to Bella Vista and a 4.5 kilometre sky train between Bella Vista and Rouse Hill.  It also includes the conversion of the Epping to Chatswood Rail Link to deliver high frequency rapid transit services.

Procurement/transaction services and project management

InfraSol Group personnel led and were directly involved in many aspects of the procurement process for the Early Works contract, D&C tunnel and viaduct contracts, the stations and rail systems PPP contract and associated service providers (independent certifiers, contract/project managers to manage the D&C and PPP contracts).  These aspects included:

  • The market sounding and industry engagement process 

  • End to end scoping, procurement and delivery of Early Works 

  • Procurement and establishment of two major D&C contracts

  • Engagement of Independent Certifiers for civil D&C contracts

  • Establishment of contract management framework for D&C and PPP contracts

  • Establishment of the service briefs and review of EOI/RFT documentation for the service providers   (contract management and project management)  

  • Development and execution of interface agreements with RMS, Sydney Trains and other government departments and agencies

  • Review of PPP contract Independent Certifier Deed to ensure that it was ‘fit for purpose’ and subsequent procurement of the preferred proponent

  • Management of the tender evaluation processes for contract management service providers and the D&C/PPP contracts

Construction Methods Development

InfraSol Group:

  • prepared an Initial NWRL Construction Methods document to inform the development of the initial cost plan, risk assessment, land acquisition and the design and environmental impact assessment teams on the context of the project activities.  The Constructability Advisors (Bamser & Evans & Peck) were then appointed by NWRL and subsequently managed by us

  • briefed the key impacted stakeholders – Councils, RMS, RailCorp and utility organisations – during the development of the EIS1 Construction Methods document. The stakeholders were engaged in accordance with the project’s impact upon their assets and operations, and

  • participated in numerous Options Studies through the development of project definition, in parallel to the EIS1 development. These were critically reviewed and led to station location adjustments, a third of the route being elevated or at surface level, and greater certainty with construction worksite definition.

The project team then focussed on de-risking the major contracts through broadly scoping the enabling works activities including demolition, traffic access for heavy vehicle, tunnelling equipment power supply, services protection / interface elimination through design / relocation and project wide geotechnical investigations.
