Ilkley-based NG Bailey, a £425m turnover engineering, IT and facilities services business, said that its rail division had been awarded the contract.
Working alongside engineering and construction group Costain, the contract will see NG Bailey design and install temporary works to facilitate the overall construction, while also delivering the detailed design of the permanent fire protection, fire detection, telecoms and security services and the installation of the electrical, mechanical, public health, fire, telecoms and security services.
As part of the contract the company said it will also offer support to the HyderWSP design team, which is working on the project, and maintain all new services installed until May 2018.
This major expansion comes as part of the Thameslink Programme, which aims to increase passenger capacity for the future and is due for completion in 2018.
Once completed, London Bridge Station will have a concourse larger than the pitch at Wembley.
Chris Raven, managing director of NG Bailey’s rail division, said: “This is a significant win and further demonstrates our reputation for excellence in the rail industry.
“We have just been recognised as Network Rail’s Supplier of the Year for 2013, for the work we have carried out at other major rail hubs across the UK.
“We look forward to delivering another fantastic project for ultimate client Network Rail, in conjunction with Costain.”
NG Bailey’s chief executive, David Hurcomb, added: “Our rail division is renowned in its field for excellence, innovation and above all the safe delivery of projects.
“The award of this contract is testament to our capabilities.”
London Bridge is the oldest terminus station and the fourth busiest rail station in London.
The station was opened in 1836 and has since underdone many changes and upgrades – currently catering for around 56 million passengers a year.
NG Bailey, which was founded in 1921 with just £100 of capital, declined to disclose the value of the deal. NG Bailey employs 2,500 people.
