During 2008 Britcon undertook the structural steelwork packages for the Peak hour subway alterations at London's underground Waterloo Station.

Works within this high profile contract saw Britcon

Supply, fabricate and install needles and temporary propping systems to facilitate the removal of existing walls
Supply fabrication and installation of Picture Frame openings including preloading and dry packing of beams
Supply, fabrication and installation of permanent staircases including balustrades and glazing panels
Assistance in the development of ongoing temporary works and sequencing in close liaison with the project designers to maintain total stability throughout

The major element of works comprised the propping of preinstalled needles prior to cutting out of the arches and for the installation of steel support members & frames. Steelwork members were pulled on trolleys to their respective work positions. Support beams were lifted into position and secured to the needles prior to installing the propping system. Props were bolted to both the needle support beams and the concrete base. An additional 45 degree brace system was 'laced' in accordance with client requirements to provide additional support to the props.

Goole Swing Bridge Reconstruction

Goole Swing Bridge is a six span bridge, situated between Goole and Saltmarsh carrying two tracks of the Gilberdyke to Goole line over the River Ouse.

Following a robust tender exercise in November 2009 Britcon was awarded a contract worth £1.8 million, from Network Rail Contractor Carillion, to carry out strengthening works to the 6 span Network Rail owned bridge. Works undertaken by Britcon comprised installation of 450 tonnes of new strengthening steelwork into the existing structure during a 6 week blockade commencing. The majority of this steelwork was secured utilising the existing rivet holes and required the removal and replacement, with specialist tension control bolts, of 45,000 rivets.

Footbridge Reconstruction

This contract involved the replacement of two existing timber staircases with steel ones and the reconstruction of the footbridge.

The main works had to be carried out during a 54 hour blockade commencing at midnight on Christmas eve.

Britcon were also responsible for the civil and building works including access scaffold required during the blockade. This project required very careful preparation and forward planning with Murphy and our subcontractors and the assembly of a dedicated team prepared to work continuous shifts over the Christmas period in very difficult circumstances.

The main lifts were carried out using a 500 tonne crane stood on the road above the station. The new staircases were trial erected in our yard, sheeted and delivered to site in modular sections to reduce time on site.

Our work was completed with a few hours to spare and the station was back in use as planned.

Dragon Bridge

A new footbridge over Harrogate's railway line has been provided at Dragon Junction in a Partnership between North Yorkshire County Council, Network Rail and Harrogate Borough Council.

This new footbridge is fully accessible for pedestrians, wheelchairs, pushchairs and cyclists. It links Harrogate Borough Council's cycle route from Bilton to the town centre and provides easier access to Granby High School from Bilton.

The existing bridge was difficult to use because there were steps at both ends.

The footbridge has been designed in consultation with the three partners and was constructed by Britcon Engineering Services for C Spencer of Barrow upon Humber in Lincolnshire.
