At £14.8bn, Crossrail is the largest engineering project in Europe and forms a major part of the Mayor's Transport Strategy for London.
This presentation will concentrate on the 21km twin bore central tunnel section under London and the stations' electrical and mechanical systems and infrastructure. Eight new sub-surface stations are being constructed, each with platforms 240m long and at depths of up to 40 metres below ground. Five intermediate shafts will provide maintenance access, intervention and escape routes with two of them also housing ventilation fans.
In particular, the presentation will explain how Crossrail is challenging some of the conventional approaches to the specification and design of electrical and mechanical equipment installed in underground stations to reduce the initial capital cost, minimise maintenance costs and save energy.
By engaging with London Underground's Capital Programmes and specialist engineers from Rail for London and Network Rail, Crossrail is utilising this combined knowledge and experience with state of the art systems to enable the maximum amount of maintenance to be carried out in the shortest possible timeframe.
3D Building Information Modelling (BIM) will be used to accurately record equipment performance, and predict the optimum time to maintain or replace such equipment, in order to improve the customer's experience and safety, minimise downtime and reduce operating costs.
Full size prototype sections of the station platform and tunnel adits have been constructed at Crossrail's research facility in Leighton Buzzard to prove the designs. The research facility is also building prototype bespoke equipment to enable the Crossrail brand and identity to be maintained. An architects impression of Tottenham Court Road Station is viewable online.
Crossrail believe that the innovative solutions incorporated into the design for this new railway will be a model for other projects worldwide.
Rhys Williams says: "This presentation is about Crossrail's vision, where we are now and how we intend to get there in 2019 and beyond".
