Central West Pumped Hydro

SEOSpecialist — Thu, 13 Nov 2025 00:05:08 +0000

Overview

The Central West Pumped Hydro ECI involved design, planning and pricing the construction of a 325MW electrical generation and storage facility, with the ability to generate 2,600MWh of energy and provide power to more than 153,000 homes.

The project included the design of access roads and water supply infrastructure, upper and lower reservoirs, penstock and powerhouse and transmission line connection.

Development of site water strategy and construction methodology, technical and market analysis of reservoir lining systems and providing input to the project Environmental Impact Statement.

CJC’s Role

CJC was involved in the ECI to optimise design, provide value engineering solutions; develop efficient work staging and sequencing, evaluate and value project risk, develop and refine the EPC program, and provide a total project cost. This included testing and refining the powerhouse design, the penstock design, and the zoned dam embankment composition of the upper reservoir, analysis of geotechnical information, dam embankment construction methodology incorporating necessary dam safety measures during construction.

Overview

The Western Harbour Tunnel will connect to WestConnex at the Rozelle Interchange, cross under Sydney Harbour between the Birchgrove and Waverton areas and connect with the Warringah Freeway at North Sydney. As part of the project, the Warringah Freeway Upgrade will make the road safer and more efficient.

This project is valued at $12.5 billion.

CJC’s Role

CJC was engaged by Roads and Maritime Services (now Transport for NSW) to undertake a constructability assessment for the development of the Reference Design for surface and structures works. This involved working closely with the RMS Project Team to develop the design, and input into cost estimates, programmes, risk assessments and the environmental impact statement.

Project Energy Connect

SEOSpecialist — Mon, 08 Sep 2025 06:05:39 +0000

Overview

The high voltage electricity interconnector, collectively known as EnergyConnect, involves the design and construction of high voltage transmission lines from the South Australian border to Wagga Wagga, 710 kilometres in length, major substation construction at Buronga and Dinawan and station upgrades at Wagga Wagga and Red Cliffs.

CJC worked as part of the pre-contracts team to develop civil construction staging and methodology for the project, identify project risk, and formulate risk mitigation measures.

CJC’s Role

CJC supported the development of the remote working strategy, sourcing and transportation of construction water, planning and developing construction access considering permanent and temporary access roads. Additionally, we managed the logistics of materials delivery to work sites, particularly concrete supply. This includes the management of cement, additives and course and fine aggregates, and working on the zoned procurement strategy identifying key suppliers.
