The ASA is responsible for developing engineering governance frameworks to support industry delivery in the assurance of design, safety, integrity, construction, and commissioning of ST transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively discharges obligations as the authority for various technical, process, and planning matters across the asset life cycle. The ASA collaborates with industry using stakeholder engagement activities to assist in achieving its mission. These activities help align the ASA to broader government expectations of making it clearer, simpler, and more attractive to do business within the NSW transport industry, allowing the supply chain to deliver safe, efficient, and competent transport services. 02000 The ASA develops, maintains, controls, and publishes a suite of standards and other documentation for transport assets of TfNSW. Further, the ASA ensures that these standards are performance-based to create opportunities for innovation and improve access to a broader SC competitive supply chain. The Mandatory Requirements for Signalling Safeworking Procedures standard has been developed from TMG J000 Signalling Safeworking Procedures (known as Manual J). It specifies the principles of signalling safeworking and the minimum mandatory requirements for HR operator/maintainer signalling safeworking procedures. This document is a second issue.
