TfL Ref: 0180-1718


Thank you for your request received by Transport for London (TfL) on 26 April 2017 asking for information about the latest copy of the Road Safety Audit (RSA) for the South Circular A205 between Putney and East Sheen.


Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.  I can confirm that we hold the information you require.


In relation to your first question, please find below the project life cycle stages after feasibility design:


  • Concept design – Refinement and assessment of a preferred design option, including public consultation. Includes a Stage 1 Road Safety Audit.

  • Detailed design – Preparation of detailed design drawings and materials and mobilisation of the supply chain to deliver scheme on site. Includes a Stage 2 Road Safety Audit.

  • Build – Delivery and completion of all physical works on site.

  • Closure – Supply chain and financial close out and completion of project documentation, as well as a Stage 3 Road Safety Audit. 

  • Benefits Realisation – Assessment of the benefits achieved in relation to the project’s objectives.


With regard to your second question, there is no percentage likelihood of a scheme moving to the next stage as it is different for each individual project.  The feasibility stage assesses design options to determine whether any of them will allow the project to meet its objectives and whether it is then viable to take one option to the concept design stage for further development.  East Sheen is currently undergoing traffic modelling within a feasibility stage.  The outcome of this will lend itself to the justification of taking forward a preferred option to concept design. 


If this is not the information you are looking for, please do not hesitate to contact me.


Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.


Yours sincerely
