LOT 1 - Engineering Design
1 June 2026 to 31 May 2027
What this lot covers

The purpose of this work is to deliver front-end engineering design for the ECH project. This package of works will expand and develop the Pre-FEED engineering to develop the technical requirements and preliminary designs to define the scope, cost and schedule of the project before committing to full execution. The purpose of this phase of the project is to establish a clear project scope, develop the design documentation to enable accurate cost estimate, identify the risks and constraints and prepare the basis for procurement and construction planning. It is anticipated that the required design works will be undertaken to varying levels of detail, dependant on the certainty of the network section, ranging from FEED level design based on location specific assets to utilisation of standard design information for less certain route corridors. The network extent is yet to be defined however it is anticipated it will be in the magnitude of the Pre-FEED. The extent of network design will be dictated in the Request for Proposal stage.

LOT 2 - Planning, Environmental & Consents
1 June 2026 to 31 May 2027
What this lot covers

Pre-FEED studies have identified the potential for 1-2 DCOs and several TCPA applications to varying maturity, noting that a number of those may benefit from Permitted Development Rights. As such the below scope of works is set out for standard requirements for a DCO and TCPA application in isolation. More detail will be provided at RFP stage. Overall project management will be undertaken by NGN; however, the PEC Consultant will be expected to include project management processes, document control, interface management, risk management and technical assurance processes.
