• A10 Footbridge
  A10 Footbridge & Cycleway

  

  Britcon have recently completed the construction of a design and build footbridge and cycleway complete with upgraded infrastructure crossing the A10 dual carriageway in Cheshunt, Hertfordshire. The construction has provided an additional crossing point from the east to the west sides of the busy A10 dual carriageway, which is one of the main arterial routes linking London with Cambridge. Specifically, it has linked the areas of Cheshunt and Waltham Cross to the east to the new St. Mary's High School to the west, being part of a Sustrans route providing an invaluable safe link for hundreds of school children on a daily basis.

  The project consisted specifically of a 35m span, 3.5m wide bridge crossing the A10 dual carriageway in Cheshunt, Hertfordshire. At either side of the bridge, structural steel ramps totalling 200 m in length and weighing approximately 140 tonnes in total were fabricated and installed. This provided a Sustrans route as a footbridge and cycleway linking Cheshunt and Waltham Cross to the east with St. Mary's High School and the remainder of Cheshunt to the west. To the west, an additional 750 m of footway and bridleway, together with a bridge over the New River, were also installed as an additional contract which was won on the basis of our record and delivery of the initial project.

  In addition to the main structure as detailed above, we also installed a 70m long, reinforced concrete structure to the east ramp linking the routes to the east back to that of the A10. This structure was finished with tarmacadam and brick clad to improve the aesthetics when viewed from the other side of the brook on Theobald's Lane.

  Linking both structures to various existing footways were new ground bearing footways and cycleways totalling approximately 200m in length, together with improvements to various existing footways and crossings.

  The construction of permanent concrete slab works and stoned maintenance areas have aided the overall appearance of the bridge and its surroundings, as well as enhancing the access for the resident farmer and any future maintenence crews who need to service the site.

  400m of new fencing and gates have also been erected, both around the perimeter of the works as well as in the central reserve of the A10 itself, providing a secure environment in and around the bridge as well as preventing the general public risking life and limb by trying cross the A10 at a non designated crossing point.

  The A10 has benefited also by the installation of 150m of new vehicle restraint system, protecting the new bridge piers as well as the improvements of the existing barrier system within parts of the site boundary.

  The whole scheme has been illuminated with the introduction of lighting columns along its length, these vary between 5 and 10m in height to provide a constant luminance whilst crossing the bridge and ramps. Some of the adjacent lighting along the A10 has also been upgraded.

  The areas which remain free from concrete, stone or steel have been landscaped to provide a natural rural habitat for wildlife, softening and improving the aesthetics of the bridge as a whole.

• Dragon Bridge
  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.

• Kensall Green Footbridge
  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.

• St Helens Station
  St Helens Station

  

  Merseytravel and Network Rail invited tenders for the reconstruction of the station, including new footbridges and lifts. The new station building and facilities, designed by SBS Architects of Manchester were rebuilt at a total cost of £6m, just a few yards from the site of the 1960s built station building. Britcon Engineering were pleased to assist C Spencer, Network Rails Principal Contractor with the Structural Steelwork requirements for this high profile project.

  The new footbridge was lifted into place in the early hours of 22 January 2007. Construction work was completed in the summer, with the new waiting rooms and footbridge opened to passengers on 19 September.

  Our involvement comprised a new station building, a new pedestrian overbridge, 2 lifts, one to each platform from the new pedestrian overbridge and 2 flights of steps, one to each platform from the pedestrian overbridge.

• Waste Water Treatment Works
  Waste Water Treatment Works

  

  Britcon were involved from the very start of the project and in close liaison with the project architects and engineers to ensure interfaces with complex M&E plant and processes were achieved. On site installation was carried out be Britcon Engineering's own teams of steel erectors and subsequently received an award from the main contractor in recognition of being part of 500,000 hours worked on site accident free.
