BANK UNDERGROUND STATION CAPACITY UPGRADE

CLIENT

Transport for London

CHALLENGE

• To be an integral part of the team delivering a 50% increase in capacity on a £500million award-winning upgrade project, by designing the utility diversions required to facilitate a 10m x 7m shaft in Arthur Street

SOLUTION

• To identity existing assets through investigatory works including a Ground Penetrating Radar survey and trial excavations
• This was followed by the design of a model delivered in Microstation 3D for integration into the project’s BIM architecture
• A concept design report was prepared for and approved by the host utilities

RESULTS AND BENEFITS

• Significant savings in utilities diversions of £3 million
• Savings in time of 6 months
• Minimising risks by negation of need for utility diversions through reorientation and remodelling of shaft, slewing of utilities and in-situ protection of assets
