Steeton & Silsden Train Station

Project overview

Casey were appointed by West Yorkshire Combined Authority and train operator Northern to build a new car park at the busy Steeton & Silsden Railway Station, extending the existing parking provision. The scheme has provided steel frame multi-storey car park with access bridge, a new lift and enhanced drainage infrastructure and ducting to support electric vehicle charging.

Our scope of works included:

• Groundwork excavations for pad foundations for the steel and concrete columns required for the vertical second level extension.
• Sequential drainage and infrastructure installation upgrades, service diversions and general ground preparation works.
• Installation of piled foundation retaining walls to accommodate variations in ground levels.
• Use of CFA, SFA, and sheet piling.
• Construction of a link bridge to connect the new car park to the highway network and associated S278 works.

Collaborative Working & Design Input

Engineering and design solution assurances were achieved through working in close collaboration with Northern, Network Rail and ASPRO. We agreed a detailed and intricate set of programmes and work sequences in order to ensure deliverables were achievable given the limited workspace areas and overhead restrictions. Our prestart workshops held both internally then externally with Northern, Network Rail and engineers determined the entire works in terms of programme, work sequences, resource requirements health and safety issues and the quality of the completed works. We provided authenticated evidence of our proposed technical and design solutions to prove that all deliverables were fully achievable.

With close collaboration at the epicentre of the approach we made substantial contributions to the structural design for the piling, retaining walls, steel frame structure and reinforced concrete works. This approach enabled us assist with the design development post tender stage when more detailed information from site location in relation to the rail-track, ground condition surveys became available. From this information we were able to offer alternative value engineered technical and working sequence solutions in compliance with Network Protocols.

Project Challenges

The immediate proximity to the rail track required close collaboration and cooperation with Network Rail. This resulted in a number of night-time working sequences to maintain progress against programme particularly when crane operations for steel erections were in immediate proximity to the running track. Monitoring track bed ballast integrity during high impact activities including piling and ground works.

One of the key results from this exercise has been the implementation of sequential night-time working when carrying out construction of the steel frames and columns in immediate proximity to the rail track to avoid disruption to the train schedules. The space restrictions required us to sequence the works away from the track during the day and implementing the use of smaller piling rigs and cranes during the steel frames and ramp construction. This enabled us to achieve smoother workflows and ensure improved cost-effective working.
