John Holland and Laing O’Rourke are undertaking a Joint Venture (JHGLOR JV) on the Sydenham Station and Junction (SSJ) re-modelling project. The SSJ project is part of the broader Sydney Metro project, Australia’s first fully automated rapid transit system, with SSJ being one of the key interchanges between the CBD and southern Sydney.
Nova Systems was engaged by Laing O’Rourke to provide Systems and Safety Assurance support to the project. Due to the project staging and the design being delivered in multiple stages, Nova Systems is working closely with the Aurecon-GHD joint venture (AGJV) design houses to develop a progressive safety case for the project, delivering Safety Assurance Statements (SAS) and Safety Assurance Reports (SAR). The SAS and SAR support each configuration change introduced by the project and allow the JHLOR to proceed to the next phase of project delivery.
With multiple stakeholders involved in the project, including Sydney Metro, Hong Kong’s Mass Transit Railway (MTR) and Sydney Trains, Nova Systems worked closely with each to produce an integrated safety case to ensure that all stakeholders were aware of their responsibilities in the project’s safety argument. A key element of the safety argument was the development of a unique security risk assessment that focused on hostile threats to members of public at Sydenham station. Additionally, SSJ is the only metro line in the world that provides a grade 4 level of automation which runs at ground level without any separation protection via a viaduct or a tunnel. Accordingly, a first of its kind, state-of-the-art security fencing with intrusion detection systems were designed to provide the required level of security protection for the network.
Nova Systems worked in close cooperation with the AGJV and the Sydney Metro Subject Matter Experts (SMEs) to provide a safety case that met the Sydney Metro security requirements.
