    Vauxhall Underground Station: Congestion Relief and Step-free Access Project

    London, United Kingdom

Project Summary

Project
The London Underground Vauxhall Station is beneath the strategic transport hub, Vauxhall Cross. The Congestion Relief Phase of this GBP 36 million project will reconfigure staff accommodations in the ticket hall, widen the gate line, and add gates. The Step-free Access Phase will construct a lift and stair shaft to connect the platforms via a new adit and cross passage. The challenge was to ensure the station remains operational during construction without inconvenience or safety hazard to passengers.

Solution
Using building information modeling (BIM) provided insights into the existing conditions of the station and how to execute the project. AECOsim Building Designer was used to model both the existing conditions and the new designs, as well as create models for each stage of construction. With the design and modeling teams spread among multiple offices on three continents, ProjectWise provided access to engineering information in one centralized location for all design stakeholders.

Outcome
Upon completion, the upgrades will achieve the London Underground objectives of catering to current levels of use and predicted levels of growth; improving passenger journey times; creating a safe and secure station environment; and providing an operationally efficient, integrated facility. On a broader scale, the project will allow faster journeys, increased capacity, step-free access from street to platform, and improved safety. It will help fulfill the vision to make life better for people who live and work in London.

Software
AECOsim Building Designer was the primary 3D design software, which was customized to incorporate the client’s own standards. ProjectWise allowed each discipline to reference the models created by others and perform concurrent engineering, which avoided rework. Drawings were extracted from the models and approved electronically through the ProjectWise process.

Outcome/Facts:
  • Using the 3D models during operations and maintenance will make locating components much easier and simpler.
  • The materials take-off tool was used to estimate project costs with a higher degree of accuracy.
  • Modeling in AECOsim Building Designer helped to plan project execution and complete the project faster.
User Quote:
  • “AECOsim Building Designer provided an increasingly flexible platform to Bechtel for a collaborative BIM environment helping in delivering high-quality iterative designs.”
