A Morgan Sindall Construction & Infrastructure and VolkerFitzpatrick (MSVF) joint venture (JV) has been appointed to build the 4.5km long Barking Riverside rail extension in London.
The overground extension of the Gospel Oak to Barking line, from the Tilbury Loop Line between Barking and Dagenham Dock stations to Barking Riverside, is part of the 180ha Barking Riverside development on which up to 10,800 new homes will be built.
Under the contract, MSVF will deliver a reconfiguration of Network Rail’s Ripple Lane goods yard to allow the extension to connect to the Tilbury Loop and construction of a viaduct over the Ripple Lane yard. This will require the viaduct to be built over the Tilbury Loop and foundations constructed between the HS1 tunnels.
It will then also require the continuation of the viaduct for a further 1.5km over Renwick Road and into the Barking Riverside development.
A new terminus station within the Barking Riverside town square will also be built. The station is due to have step-free access from street to train.
The award of the contracts had been delayed due to “bid returns from the two bidders being higher than anticipated” a recent Transport for London (TfL) board paper said.
In light of this sponsor, TfL said it had reviewed the scope and value engineering opportunities on the programme which has been included in a ‘best and final offer’ process in the award.
It also said that the grip 5 signalling design, low voltage power and other design elements were not completed on time to support the invitation to tender issued on 13 April.
To avoid delaying the major works contract tender documents, TfL said the design was issued in advance, but both bidders had requested an extension of four weeks to the tender period to review the designs issued after the invitation to tender date, which was granted.
Overhead line electrification switch works planned for Christmas 2018 will be impacted by late award of contract due to reduced mobilisation time for the successful main works contractor TfL said. But it went on to say that the works were being procured as a separate package to mitigate the impact to completion dates.
TfL said despite the delay, there would be no impact on the opening of the line in 2021. Construction is due to start in early 2019.
To date, £22M has been spent on the project.
TfL managing director of surface transport Gareth Powell said: “Investing in transport infrastructure unlocks and supports homes, jobs and economic growth.
“Awarding this contract to build the London Overground extension is the next exciting step in the Barking Riverside development, which will enable the delivery of up to 10,800 new homes and the creation of new healthcare and leisure facilities.”
The service will operate with four trains an hour and feature electric London Overground trains with air-conditioning and walk-through carriages, for customer comfort.
