Green Lane / Great Western Road

The Green Lane (Great Western Road) Project on behalf of BFK/Crossrail involved the construction of 6 shafts (by underpinning method) and nearly 600m of pipe jacking.

The scheme was required as the existing sewer going under Network Rails Great Western Rail lines and London Underground would have clashed with the new Crossrail line. As a result, the existing sewer was abandoned and replaced with a new 1.2m pipe at a lower level. As part of the works, Barhale were responsible for the detailed design of the scheme involving consultation with Thames Water, Network Rail and London Underground. Initial works involved the location and diversion of all services at the shaft locations including Gas, Water, Electrical & Fibre Optics.

Fisher Street Kingsway Tram Tunnel

The Kingsway tunnel was built in 1906 and once carried trams between Aldwych and Holborn. It had been used by the London Borough of Camden for storage since its closure in 1952 but it has now been reopened by Barhale, sixty years later, to enable an essential grout shaft to be constructed.

This was an extremely interesting and challenging site location due to space constraints, media interest and the fact that the tunnel was a protected heritage structure.

Datchet Tunnel Relining

Datchet Pumping Station (PS) is a key asset and up to 60% of London’s daily water demand can be met by the twin intakes from the Thames. When the decision was taken to switch it off, to enable Barhale (via the Optimise joint venture) to complete the essential Tunnel Relining project, Thames Water needed to grasp the opportunity to successfully complete all outstanding remedial work in the station at the same time.

The Datchet project is part of a programme of relining being carried out by Optimise. With 3km relining at Wraysbury and 1km from Queen Mother Reservoir to the pumping station already completed, the Datchet stretch will be followed by a 3km section from the Queen Mother to the outlet.

Riversdale Swing Bridge

Barhale were awarded this £1.1 million contract to replace a pedestrian footbridge. The project saw the replacement of a dilapidated non-functioning timber swing bridge across the River Weaver with a 28 tonne steel bridge, incorporating a rotating 32.5 metre section. The bridge is restricted to pedestrian and cycle traffic only and was manufactured by BCS, Barhale’s in house fabrication workshop in Walsall.

Due to the extremely restricted access to the site, the only means of bringing in plant, equipment, materials and the bridge components was down the river on pontoons. The bridge sections were delivered to the wharf at Hartford Bridge (1.5 miles upstream of the site), lifted by crane onto the pontoon and moved down river by a tug, before arriving at the site and being lifted into position.

Charing Station Footbridge

To introduce cost saving efficiencies within their own organisation, Network Rail engaged Barhale through the NR route team, as part of the Kent Route Project DIME, rather than using the traditional NR Infrastructure Projects route. This was the first time that this project management route had been implemented.

The scope of the project was to construct a new steel footbridge within Charing Station to replace a life expired Exmouth type structure; the scope included its demolition/ removal following the successful installation of the new bridge.

Design and build project from GRIP stage 3 to 8 and involved gaining planning approval for the repositioning of the new bridge from the district council. Barhale working closely with our designers Tony Gee & Partners, the design we developed incorporated BCS fabrication’s extensive experience of fabricating steel footbridges.

The new bridge was scheduled to be installed and the existing concrete structure dismantled during a 57 hour OROR possession 21st to 22nd September 2013. This date was successfully met.
