Kirtling Street Temporary Works - Thames Tideway Tunnel

The Brief

Flo JV appointed BAM Nuttall Ltd (BNL) to design and construct the marine side temporary works required for the construction of the Thames Tideway Tunnel at the Kirtling Street site.  BNL appointed Robert West Consulting to design the temporary works.

The temporary works consist of delivery and removal facilities to allow for the delivery of the tunnel boring machine and tunnel segments and removal of spoil from the tunnel bore and shaft. All spoil will be exported by barge along the river to reduce the number of heavy goods vehicles on the roads.

The temporary works solution developed by the BNL/RWC team comprised drilled and socketed tubular piles, prefabricated steel superstructure, and pre-cast concrete deck.  Additionally, support structures for a fixed conveyor with pivot arm and berthing structures for barges were designed.

Our services included civil, structural and geotechnical design for the Temporary Works as well as the definition of all components required for the construction of the temporary works (piles, steel structure, pre-cast concrete deck)

 

Leighton Buzzard Footbridge

A pedestrian footbridge, originally built in the late 1800’s, had been identified as unsafe and was closed to the public in January 2019.

Robert West engineers were commissioned by Leeke Associates (lead designers for the scheme) to undertake the Temporary Works design for the removal of the bridge in a similar way to that shown in our video of the removal of Oxford Road footbridge.

The footbridge provided pedestrians and cyclists with a method of crossing from one side of the railway line to the other.  Our Transport Planners are undertaking a feasibility study to identify the affect of the removal of the bridge for members of the public.

Romford And Ilford Stations Temporary Work Design

As part of the Crossrail programme, Romford and Ilford stations in Essex are receiving significant improvements.  For Romford station this means improvements to the station facade, ticket hall and lifts http://www.crossrail.co.uk/route/eastern-section/romford-station) and Ilford station will be rebuilt http://www.crossrail.co.uk/route/eastern-section/ilford-station).

To facilitate the installation of the permanent works scheme designed by Atkins, Robert West were engaged by our client, principal contractor VolkerFitzpatrick, to provide temporary and enabling works including demolition sequences, assessments of existing structures, excavation support and various temporary foundations and other structures.

Thames Tideway Blackfriars Bridge Foreshore Temporary Western Cofferdam

Flo JV appointed BAM Nuttall Ltd (BAMN) to design and construct a Temporary Cofferdam at the Thames Tideway Blackfriars bridge Foreshore Site. BAMN appointed Robert West Consulting with Byland Engineering Ltd. operating as geotechnical advisor, to complete the outline and detailed design of the Temporary Cofferdam Structure.

The Temporary Cofferdam is required to enable the construction of the permanent works proposed at the Thames Tideway Blackfriars Foreshore Site. The permanent works consist of the construction of a tunnel shaft, outfall chamber, culverts and new river wall, in order to intercept flow from the existing Fleet Main Sewer CSO located in the Victoria Embankment river wall. The brief for the required functionality of the Temporary Cofferdam, included: 

  • retain reclaimed land south of the existing river wall to enable construction of the permanent works;
  • retain river water to enable construction of the permanent works;
  • provide a berth for construction barges during construction of the permanent works;
  • act as a working platform for construction plant traffic over the cofferdam;
  • provide temporary flood defence at a minimum level of 105.5mATD;

The Temporary Works solution developed by Robert West comprised a twin walled back to back tied temporary steel piled cofferdam infilled with dredged sand, to be located within the River Thames. Robert West engineers also proposed bespoke structures to seal the cofferdam against the existing Victoria Embankment river wall.

Our services included civil, structural and geotechnical design for the Temporary Works, as well as the definition of all nautical equipment required for the operation of the cofferdam (bollards, fenders, access ladders etc.). 

The Warwick School

A new school building for staff and students is to be built on the existing site providing up-to-date and extended facilities.

The building programme included an expansion from six to seven form entry to provide more school places for children in the local area and planning permission was being sought by our client accordingly.

Robert West were commissioned to undertake an assessment of the potential impact of the expansion on transport in the immediate surrounding area.

Twyford Station - Foundation Design

Robert West are once again involved with the Crossrail project as the changes it brings require modernisation across the rail network.

Crossrail trains utilise Driver Only Operation (DOO) technology and require new cameras and associated cable routes at Crossrail stations to enable the system to operate.

At Twyford Station in Buckinghamshire Robert West were commissioned by Fourway Communications to carry out the civil design for the DOO scheme. This included the design of the concrete foundations for the DOO cameras, the associated cable routing, canopy camera brackets and a structural assessment of the existing station canopy.
