National Level Crossing Programme – Kemps Footbridge

Barhale’s subsidiary, BCS Fabrications, were contracted by Network
Rail (with Kier as the principal contractor) to design, fabricate and
install a new footbridge near Balcombe in Sussex, as part of the overall
National Level Crossing Programme (NLCP). Kemp’s foot crossing,
which links the B2036 road with Stumble Field Wood and Balcombe
village, was used previously to cross the dangerous 90mph main
Brighton railway on a bend.

Network Rail were under pressure from the local authority to maintain
a local right of way, but with only three disruptive possessions
available during the final quarter of 2014, it provided a sizeable
challenge to complete the construction in the shortest time possible.

London Sustainable Industries Park

Barhale have successfully completed a £1.38m design and build
contract for the Greater London Authority (GLA) at Dagenham
Dock in East London. As part of a regeneration scheme for unused
industrial land, the GLA are selling serviced plots of land within the
Mayor of London’s first clean technology commercial park.

An important part of the regeneration required upgrading the
local sewerage infrastructure. Along with our design partner, GHA
Livigunn, Barhale were engaged to design and construct a 6m
diameter x 14m deep, segmental caisson pumping station, including
associated MEICA installations with two 66 l/sec pumps.

Yews Lane Bridge Replacement

Barhale were awarded this design and construct project by Network
Rail, to replace the railway bridge along Yews Lane in Helsby, Cheshire.
This occupation bridge provides the only access route to Hope Farm.
Having failed its capacity assessment, there was a need for it to be
replaced due to the weight limits imposed. This stopped vehicles in
excess of 6 tonnes accessing the farm, creating problems with feed
and livestock movements.

The scope of work comprised demolition of the existing bridge,
design, fabrication and installation of the new structure. Design was
undertaken by our sub-consultants, Crouch Waterfall and Partners,
whilst all other key elements were delivered in-house, including
fabrication of the new steel deck at our fabrication workshop in

Albrighton Flood Alleviation Scheme

Barhale were awarded this £6.4 million scheme by Severn Trent Water
to upgrade the sewerage system within Albrighton, Shropshire.
The village of Albrighton had experienced substantial flooding in
recent years, due to lack of capacity in the existing sewerage system,
coupled with the volume of surface water flowing into a local brook.


Barhale offered an innovative solution to the client through carrying
out micro-tunnelling to a curved profile. This was one of the first
micro tunnels in the UK to be cut on a curve through rock and
provided a £300,000 cost saving to the client, Severn Trent.

Roundtree and Greenford Road

Barhale were contracted by Network Rail to undertake a construct
only package of two schemes in North London. The first scheme on
Roundtree Road involved the demolition of an existing footbridge, the fabrication and installation of a replacement steel structure, as well as the construction of associated foundations, footpath and

The second scheme on Greenford Road consisted of the
refurbishment, grit blast and painting works to an existing footbridge,
as well as de-vegetation and brickwork repairs.

National Grid Cable Tunnel

National Grid supplies electricity through transmission networks, operating at 400kV and 275kV which connects to the three substations at Hackney, St John’s Wood and Willesden to supply points where power is fed into the local distribution system.

Within London, a network of 275kV cables were installed in the 1960’s which needed replacing, as they had reached the end of their technical life. Due to increasing electricity demands, the cables were upgraded and replaced with 400kV cables which were installed within a deep level tunnel.

Fisher Street – Shotcrete

Crossrail is Europe’s largest railway and infrastructure construction project, under way mainly in central London to provide a new high-frequency commuter/suburban railway service.

Barhale undertook a technically challenging project in Holborn, in central London, working for BFK under the Crossrail project.

The scheme involved constructing a 30m deep shaft solely through the use of sprayed concrete lining (SCL) technique, due to its flexibility in use. The shaft will be used for access into the underground tunnels.

Roydon Water Treatment Works

This contract consisted of the construction of a new Rapid Gravity Filter structure and associated ancillary plant, to provide improved treatment of potable water supplies which suffer from high concentrations of Iron and Manganese. The existing plant was fed from two local boreholes but was restricted in output, due to the water quality issues. The new works will allow the plant to address both these issues.

Barhale were responsible for the overall design and construction of the works, taking the concept design from the client and developing the entire (MEICA) detailed design. Barhale’s in house design team were responsible for the overall design management, providing the design for the main civil structures, pipelines, duct arrangements, hard and soft landscaping and security upgrades.

Ashford WWTW Extension Project

As part of Southern Water’s £1.8 billion AMP 5 programme, Barhale undertook a £12m design and construct upgrade to Ashford Treatment Wastewater Works, enhancing capacity to allow for population growth in the area under our Barhale Trant Utilities (BTU) JV.

Through our corporate design and construction procedures, Barhale, working in collaboration with our design delivery partner URS and Southern Water, established a series of design workshops to ascertain the exact objectives and milestones the project would need to deliver. The challenges that all project stakeholders faced on the Ashford project was the limited as built design and assets information for the existing site.

Wyke Gardens Dual Manhole Study

Through their expert tunnelling experience and customer care, the Barhale team at Wyke Gardens, Ealing, were able to greatly reduce long standing flooding in to the River Brent, whilst maintaining traffic flows and customer relations in a densely populated area of west London. The Wyke Gardens storm water network in west London had a history of regular flooding and discharges into the River Brent. These discharges were polluted with foul water flows from 40-50 illegal or misconnections to the storm water network.

Barhale was selected by Thames Water to:

Construct a new CSO chamber and online storage tank to reduce the discharge events and provide a new static screen to remove the solids from any overflows.

The works were based in and around the busy A406 (North Circular Road), leading to and from the Hanger Lane Gyratory System – one of the busiest junctions in London, which incorporates 10,000 vehicles an hour.
