Asset Standards Authority
The Asset Standards Authority (ASA), an independent unit of Transport for NSW, is the authority on network design and standards for transport assets across NSW.
The ASA is responsible for developing engineering governance and frameworks to support industry delivery in assurance of design, safety, integrity, construction and commissioning of transport assets for the whole asset life cycle.
The ASA is also responsible for providing the standards that industry organisations can use to deliver projects and manage transport assets across NSW in a more innovative, safe, and efficient manner.
