VAUXHALL UNDERGROUND STATION: LONDON


The Vauxhall Underground Station modernisation is part of Transport for London’s ongoing investment into London’s public transport network to support economic growth and employment opportunities.

The £45m project entailed reconfiguration of the station’s ticket hall to accommodate extra ticket gates and wide-aisle gates, as well as the refurbishment of the stations’ subways, ticket hall and stairs. The main part of the project was to make the access to the station step-free, enabling the station to handle 40% more passengers by installing a new shaft and lift between the ticket hall and platforms. A particular challenge was posed by the station remaining fully operational while the construction work took place between 2013 and 2017.
The main contractor selected was Bechtel, who proposed an innovative, new way of constructing the elevator shaft from below ground level, as well as utilising a sprayed concrete lining technique to save £9m from the total construction costs.
The principal requirement for the shaft was to accommodate the lift, which had to be constructed within the vertical concrete shaft and therefore required detailed co-ordination between all the existing structures, such as tunnels, ticket hall and the roof structure above.

Atom Consultants principal job was to create a BIM model of all the essential existing and new elements to enable total co-ordination to take place. We were also responsible for the structural design of all the structural elements providing support to the lift within the shaft and the escape stairs, which spiraled around the perimeter of the lift enclosure. As the construction proceeded, the access was available to make accurate measurements of the existing elements, and this information was fed back into BIM to adjust the model based on the actual survey conducted. As a result, the design was adjusted to fit within the actual building dimensions, whilst still maintaining the tight tolerances and necessary access space for lift maintenance engineers. Also, the entire model had to be co-ordinated with the London Grid, so that the facility could be incorporated into the London Underground Asset Register.
Additionally, all work had to be completed and independently reviewed in line with the precise standards to meet the stringent approval process for the London Underground.
Working in wonderful multi-disciplinary teams, which manage to collaborate efficiently is what made this project a particularly enjoyable one.

Winton Primary School Sports Hall- London

The London Borough of Islington had a requirement for a new sports hall to be used out-of-hours by the local community and it was to be built on the roof of and existing school- Winton Primary School.

To minimise disruption to this ‘live’ site, a modular approach was adopted. All components of the build were pre-fabricated, starting from the structural steel wall and roof panels and ending with the beautiful western red cedar clad external facade.
