Cadweb.net starts its first BIM Project on part of the £14.8Bn London Crossrail Project.

January 2012

Cadweb has been appointed to provide the model exchange, storage and management services in conjunction with our partners Rapid5D  a section of the Giant Cross Rail project. The project will ease the currently limited capacity of rail traffic into London Bridge Station.


The project known as the Bermondsey Dive under is a massive piece of engineering being undertaken by Hyder Consulting and Hoctief, the German Construction company. There are a number of Viaducts that need to be re-built/routed. The purpose of the project is to get Thameslink trains to/from the Brighton direction over the top of the South Eastern tracks to/from Charing Cross. In addition the Tanners Hill fly-down will be doubled, remove many of the conflicting train movements. DC Power supplies have been upgraded and a new depot will be built at Three Bridges after the Olympics

The result is that all services approaching London Bridge are lined up for their destinations beyond London Bridge - Cannon St and Thameslink services on the north side, Charing Cross services in the middle and services terminating at London Bridge on the south side of the viaduct.

The map below shows in schematic how the network will look before and after the project

These viaducts need some work, but the brickwork appears to be in a relatively good condition. The two left-most arches will contain the up and down lines of the new connection, whilst the right-most will be returned to use as a public footpath.


Following the appointment of Hyder and Hoctief Rapid5D were engaged by Hyder to model the project in 5D using the existing 2D tender and design drawings. It is planned that the entire project will be modeled in 3D, planned and sequenced in 4D and costed in 5D. All 5 Dimensions will be in one piece of software namely, Vico’s unique integrated 5D BIM program. This will be unique to the Crossrail project and very probably a first on any project in the UK let alone one so large and complicated.

 

Cadweb.net is being used as the data exchange, for the management and storage of all the incoming files required to produce the 5D models and the 5D models output themselves. Since the project started operations more than 40Gb of data has been exchanged, stored and audited on the system.
