Costain were awarded the £400m contract to redevelop London Bridge Station in late 2011 by Network Rail. The redevelopment is part of the Thameslink programme, which will significantly increase the number of trains passing through the station.
Costain are carrying out the detailed design and delivery of this five year project (due to complete in 2018). It will include a new concourse at street level and redeveloped entrances with improved ease of access to and from the station. Capacity will be increased from approximately 50 to 70 million passengers per year.
The project raises a number of challenges, not least the need to keep the station open and fully operational throughout the duration of the project. Costain will utilize a number of new technologies to help in the process, including advanced BIM, augmented reality and the MobiCloud Site Diary app which is being deployed on iPads.
The Site Diary app is one of the MobiCloud trial applications. It is designed to make it easier and quicker for site engineers to record information about events on site, which historically has been done manually. It can include photographs and GPS location and to makes relevent records much easier to locate at a later date.
