Keltbray has successfully completed the first phase of the main demolition work at London Bridge station within budget and to programme


T


his work is part of Keltbray’s £25 million contract for Costain and Network Rail to create an improved


and more spacious station for passengers with more frequent train services by 2018. More specifically, Network Rail’s


plans involve improvements to the rail infrastructure around the station, a vast new concourse that is bigger than the pitch at Wembley and two new station entrances at street level. During the first phase Keltbray had more than 100 people working on the demolition of three platforms and 12 existing brick viaducts. This work was carried out while causing minimal disruption to neighbours and passengers, and allowed the continued operation of trains.


Keltbray project manager on site, Nick Smith, said: ‘Our biggest technical challenge was to ensure the stability of the remaining structures during the demolition process. We solved this through the installation of temporary works including a gravity concrete retaining wall to support the live platforms and tracks. ‘Four machines worked simultaneously


along a 150 metre long face to progressively demolish the arches in 1.5-metre strips. Maintaining this sequence was essential to avoid an uncontrolled collapse. During the works over 25,000 tonnes of material was removed from site with wagon movements peaking at over 150 loads per day.’ At London Bridge all parties on site are


working to BS 11000 Collaborative Business Relationships. According to Smith, this has facilitated a stronger joint working approach that has been instrumental in completing the first phase early through a focus on mutual benefit through the optimisation of efficiency.


Keltbray has contributed positively to


the good health and safety record on site by running cycle safety events for the public, and training for Costain, including asbestos and plant awareness courses. By helping Costain to facilitate


employment opportunities for the community in Southwark, Keltbray is also enabling section 106 success, and recently delivered an intensive two-day training and assessment session for 13 applicants to provide them with the health and safety certification to apply for

work in construction, and help them gain the confidence to apply and attend job interviews.


In terms of environmental solutions, Keltbray is deploying only low-emission vehicles on site as well as state of the art


plant which feature low sulphur diesel engines to further minimise emissions.
