Barhale Installed a boat ramp for Putney Rowing club who had previously had to access the River Thames 200m upstream from the clubhouse.
Although accustomed to working with water, the tidal constraints of the river made this project challenging
The River Thames is tidal – water levels at Putney rise and fall twice a day approx. 4.5m so riverbed works were scheduled for the 4 to 5 hours of low tide.
The ramp was divided into manageable sub sections which could be safely excavated and concrete poured within 2 hours, allowing a further 2 hours setting time.
Barratt Developments sought to construct a block of low rise houses in the Rothershide area of London. To achieve this, the existing foul and storm trunk sewers, that were running across the centre of the site, needed to be diverted to the perimeter. The work comprised the installation of clay and concrete pipes for the new route and the forming of “on-line” manholes through which to break into the existing sewers, in order to divert the flows. Once diverted, the old sewers were abandoned. The Client provided a design that showed the new route. Flows were maintained within the sewers throughout the duration of the project.
Barhale were awarded the construction project by LUL to replace the railway bridge along the Metropolitan line in Rickmansworth, Hertfordshire. The bridge is part of the railway line between Rickmansworth and Moor Park station. The major concerns with the existing structure were the capacity to resist two horizontal loads, vertical displacements and the load capacity of the old deck.
Barhale carried out a detailed work programme for the possession period, including contingency plans to ensure that the works will be completed on time. During the bridge replacement works, not only did Barhale succeed with its works but we also made up for third parties delays and provided other subcontractors with their own resources to achieve the target delivery.
Along the project, Barhale demonstrated a hands-on spirit with a permanent collaboration with the client on the several design issues and challenges.
In Battersea, the Barhale team were able to draw upon their wealth of tunnelling experience, to develop innovative solutions to mitigate un-foreseen changes to the scope of works. Their proactive approach to potential problems saved the client time and money in delivering a very tight programme.
Following the excavation of the reception cofferdam; designed to enable retrieval of the tunnelling boring machine (TBM), it was established that the existing sewer was not in the location shown on the drawings. Also, the area surrounding the sewer was overlaid by a dense zone of utility services including an Extra High Voltage (EHV) trough and large diameter portable water mains; consequently it was no longer possible to retrieve the tunnel boring machine from the cofferdam.
Barhale were awarded the design and construct contract for the Access for All (AFA) station upgrade works to Camden Road Railway Station. AFA was a major development programme that aimed to improve accessibility to 160 train stations around the country.
The station is an 1870’s grade II listed building sited on a series of brick arches, located in a London urban inner city location, surrounded by a combination of commercial and residential buildings.
Two new lifts were provided from station concourse to platform level.
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.
Barhale were awarded the design and construct NR9 contract, in conjunction with our design partners at Tony & Gee, to undertake the £3,175,000 scheme at Bolton to regenerate the train station and enhance the general customer experience.
The project was high profile within Bolton’s local community and media. The scope of the works included the refurbishment and enhancement of the platforms, construction of new platform canopies and modi cations to station buildings such as the ticket office, travel centre and waiting rooms. In addition, Barhale were tasked with making improvements to the M&E, CCTV and retail telecoms systems.
Due to Barhale’s performance throughout the project, Network Rail awarded additional works to the value of £350,000 to Barhale, including the refurbishment of the station footbridge, adding new roller shutters to the ticket office and more general civils and building works around the station.
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.
Barhale were contracted, by the Olympic Delivery Authority, to undertake the £3.7 million scheme to install both temporary and permanent access structures to West Ham Station. This provided a pedestrian route for travel between West Ham Station and The Greenway, for access to the Olympic Park. The temporary structures were dismantled post-Olympic Games and stored for possible re-use in the future. The project was split into three phases:
Phase 1
Barhale installed a long temporary footbridge with two flights of stairs over the West Ham District Line. The walkway was positioned on 50No Screw Piles, embedded in the East Bound LU Embankment.
Phase 2
Construction of a temporary staircase with a 16 passenger disabled lift between Manor Road and the Greenway. Barhale reconstructed a 300m permanent step free DDA compliant access ramp from Manor Road, running parallel to the Greenway.
Phase 3
Barhale dismantled part of the temporary works once the Olympics finished, with potential for the steel walkway and staircase to be re-used in the future.
As part of the development of a disused Victorian building that was part of the historic Smithfield meat market in Farringdon central London, Barhale was contracted to replace the tunnel crowns above the upgraded Thameslink railway lines which run beneath the building.
Barhale were required to seal the site above from the railway corridor below with a reinforced composite concrete slab on the existing wrought iron/early steel girders in area D1 and on new steel beams in areas D2 and D3.
