Story

The Barking Riverside is a part of the larger Thames Gateway re-development zone which is transforming East London. It is one of the largest housing development sites in the UK and one of the largest brownfield developments in Europe. The master plan provides for a new district centre consisting of commercial offices, retail premises and other local amenities, which will be served by new rail infrastructure, extending the existing Gospel Oak rail line from Barking Station to a new Barking Riverside station in the new town centre.

The client’s design team opted for a concrete viaduct into an elevated station, in keeping with the existing local DLR line network and to suit the local topography, local road network and national grid overhead lines.

We supported MSVF during the initial tender under a PCSA agreement, collaborating with all stakeholders to develop the smart design solutions, logistics strategies, methodology and programme to deliver greater assurance and certainty.

Our scope involved the construction of a 1.5km concrete viaduct and new concrete station structure to an F4 finish.

Industry Recognition

Our approach to HSEQ at the Project was central to the Barking team being awarded the prestigious Beacon Award by Transport for London.

Enabling & Substructure Works  

Our team fully analysed and understood the Geotechnical Investigation and implemented lime and cement stabilisation of the existing ground in order to provide the temporary haul road along the trace. This solution negated the need for a costly and time consuming import and install of granular material for a temporary haul road, which reduced the risk to the environment and disruption to the local road network through major reductions in lorry movements.

The GI revealed seams of sand and ash deposits from the prior power station, which would impact the stability of the ground during pile cap construction, our team implemented an innovative temporary works solution involving the use of large NTS dig and sink trench boxes, providing the benefit of above ground hydraulic horizontal supports, this solution allowed unobstructed working space for the construction of the pile caps, this solution replaced the intended use of local cofferdams and provided major time and cost savings.

In-House Design

Because of the pour sizes to cast the concrete elements, we asked Kingscote Design Limited, our in-house permanent and temporary works designer office, to carry out a detailed review of the structural performance when casting and curing the RC elements. They ensured all the necessary control measures were in place before the construction team began.

Temporary works designs for the cofferdams, including bridge abutment formwork systems, support structures for bridge beams for the fixing to the bearings, and diaphragm beams were developed in-house by Kingscote Design Limited.

Viaduct Structure

The 10m high Viaduct consisted 41 number 25m decks which spanned between piers which were supported on precast Y beams. The precast Y beams sit on the elastomeric bearing plates on full width as well as in situ concrete pier walls, founded on pile caps and piled foundations.

Kingscote Design supported our construction team with temporary and permanent works solutions for all aspects of the viaduct construction, from soil stability through to formwork and falsework solutions for the pier walls, and falsework supports for the bridge deck and bearing installation. Pier Wall Construction (42 in total) involved the use of modular steel formwork systems and resulted in an exceptional finish.

Precast

Our extensive use of pre-fabrication was a key factor in achieving the high quality required by Transport for London.

Bridge decks and precast parapets were installed using cantilever platforms to the perimeter. This was coordinated with the installation of the precast Y beams which were lifted into position in sections, the track distribution slabs, and the installation of GRP soffit panels forming deck soffits.
