Challenging space constraints
In December 2016, the Mayor proposed a new accelerated Step-Free Access Programme with a confirmed investment of £200m over five years. In response to this Transport for London (TfL) committed to making more than 30 underground network stations step-free by 2021/22.
Space at most of the stations is extremely constrained making it challenging to identify viable options. We collaboratively assessed all the options as a team with the client, premises engineers, structural and MEP engineers, construction planners and cost consultant to ensure the best were taken forward.
The Mayor’s tight timescales made it essential that our option selection process was thorough and fully auditable. It made sure that there was no room for doubt or re-design during the later design phase. We agreed the options with a wide range of stakeholders to ensure all potential issues were identified and passenger experience maximised.
Collaborative design and transparent delivery
The design process used workshops enabling the design team to work closely with the client and discuss input from all disciplines jointly as one collaborative group. The process ensured transparency of delivery and an early opportunity for Transport for London to comment on, discuss, and agree options, details and any technical issues.
The client was very satisfied with the process and its outcome, which led to further commissions on the stations and the development of seven proposals through to concept, detailed design and delivery. Debden, Ickenham, Wimbledon Park and Subury Hill are the first stations to complete and due to be followed by Burnt Oak, Hanger Lane, and Northolt.
