To facilitate a new 225,000 square foot extension to the INTU Lakeside shopping centre in Essex, Barhale were required to divert existing utility services away from the new building footprint by carrying out extensive open cut excavation.
The new extension will act as a focal point for the shopping centre, housing numerous leisure facilities including; a bowling alley, various food and drink outlets and an interactive family entertainment centre.
There were three existing services, which clashed with the footprint of
the new building:
• Potable water main
• Gas main
• HV electricity ducting
This project involved the refurbishment and strengthening of an existing vehicular access bridge, which was displaying signs of severe corrosion. The bridge spans a spur section of the River Thames; connecting the “mainland” of Old Windsor to Ham Island.
To enable the works to take place under the bridge Barhale secured a permit with the Environment Agency (EA) to block the river from early November 2016 until late January 2017, with a temporary pontoon system. The majority of work was then permitted to take place from on top of this pontoon.
In order to reduce the risk of internal and external sewer flooding to 36 local properties, Barhale were contracted by Thames Water during AMP 5 to install flood alleviation measures in the Chamberlayne Road area of Brent, North West London.
To increase the network capacity, the scheme was originally proposed as a series of open cut sewer upsizing works, however due to time constraints on the programme and the disruption open cut trenches would cause to the area, Thames Water asked their partners to propose an alternative solution. Barhale suggested a micro tunnelling solution in order to provide the following benefits:
• Minimise the disruption to the local roads and residents
• Use the large diameter jacking pipes to maximise the online storage capacity (additional 800m3)
• Minimise the risk of digging around buried services in the highway
• Shorten programme duration
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.
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.
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
Walsall.
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.
Barhale, through Optimise, were instructed to isolate and repair a burst
section of a 20” water main, as it crossed over the New River aqueduct,
close to the Hornsey WTW. The Emergency works carried out for
Thames Water were completed in 2 phases.
Phase 1 consisted of isolating the water main 500m away from
the damaged section, using a linestop and installing a valve
arrangement.
Phase 2 of the works included; twice daily infusion works to
maintain pressure in the live network behind the newly installed
valves, investigative works including boreholes and NDTs and the
replacement of the damaged section of the pipebridge.
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
fencing.
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.
Delivering an iconic pumping station as part of the Olympic development site. Barhale was awarded a £21 million contract by the ODA, to design and construct a primary foul sewer and pumping station, as part of the Olympic Park development.
The Primary Foul Drainage is a park wide utility which collects, conveys and discharges flows from the main venues, buildings and residential developments during the Olympic, Transformation and Legacy Modes. The system receives flows from the secondary foul drainage system and conveys flows by gravity to a terminal pumping station which discharges to the Thames Water Northern Outfall Sewer.
This highly complex, multi-disciplinary scheme included the construction of 2km of deep sewer in tunnel, 13 No. shafts ranging in size from 4.5m to 12.5m diameter and a large pumping station which formed the centre-piece of the contract.
