Barhale has been awarded a design and build contract to provide water infrastructure at the under-construction Barking Riverside railway station.
Barking Riverside Limited (BRL) has appointed Barhale to install a new foul water pumping station at the terminus which is currently being built as part of the £260M extension of the Gospel Oak to Barking Overground Line.
BRL is the joint venture between L&Q and the Mayor of London spearheading Barking Riverside, the mixed-use development that will regenerate the 179ha brownfield site of the former Barking Power Station.
The new London Overground station that will service over 10,000 new homes planned in East London.
Barhale will enter a three month design phase with design partner Nicholas O’Dwyer before the main construction work commences in May 2022.
The programme will also include laying a linking length of foul sewer to a new rising main and the drainage within the pump station to connect the incoming sewer to the inlet chamber and to a new emergency storage.
A key consideration is overcoming the challenging ground conditions, predominantly tidal alluvium, presented by the location alongside the River Thames.
Barhale regional manager Daniel Meadowcroft said: “Our approach will see the originally-specified, shallower-laid, large diameter pipes replaced by a storage tank.
“Given that we are literally working on the banks of the Thames, it will provide a firmer foundation and minimise the risk of settlement.
“It’s a great example of how we are able to draw upon our extensive expertise in overcoming engineering challenges to find an optimum solution.
“Barking Riverside is a hugely important project to help build the transport infrastructure for a new community in East London. We are very excited to be playing a part.”
Barking Riverside station is scheduled to open later this year.
Main works contractors Morgan Sindall and Volker Fitzpatrick are adding 4.5km to the London Overground Gospel Oak to Barking line from Barking to a new station at Barking Riverside.
The four-train per hour service will support 4,000 homes currently being built at Barking Riverside and directly unlock a further 6,800 homes.
The line was originally earmarked to open at the end of 2021, however issues diverting utilities combined with Covid-19 restrictions have been blamed for delays and cost increases.
Transport for London has previously announced that the extension will not open until July 2022 at the earliest.
Under the worst case scenario outlined by TfL, the opening date could be pushed back until December 2022 – one year later than the previous December 2021 opening date.
The project’s estimated cost has also increased by an additional £32.5M, up to £327M. The original estimated cost of the line was set at £263M, however that increased to £294.5M in 2018.
