Technical Supplier Assurance (TSA) Framework

Technical Supplier Assurance Framework

The Technical Supplier Assurance (TSA) Framework document outlines arrangements for managing the development, implementation and management of technical outcomes for transport assets.

The framework focuses on the supply of technical services and products to TfNSW and defines the assurance required to give justified confidence that the technical aspects of an asset or service change have been appropriately considered and conducted.

The intent of the framework is to provide assurance that technically capable organisations and technically competent individuals are working on our assets.

The framework is available here (PDF, 1.16 MB).

The framework is underpinned by the Technically Assured Organisation (TAO) Scheme which recognises organisations technical capability. Entities that seek to provide self-assured engineering and asset services to Transport are required to become a TAO.

Details of the TAO Authorisation Scheme are available here.
