Global Rail Construction Limited (GRCL), has secured a new railway civil engineering project at New Road, Welling on behalf of partner BAM. The project is located between St Johns and Crayford Creek on Network Rail’s South East Route rail infrastructure.

The core scope of GRCL’s works covers the supply and installation of 8m long steel sheet piles in order to construct a 200m long cess wall to stabilise the railway embankment. These works will be undertaken during a nine-day closure of the lines in February 2020. The full scope of works will be completed by June 2020.

Over the years, the embankment has shown signs of soil creep and localised slumping, resulted in tilted and misaligned troughing routes and ravelling of ballast from the cess shoulder onto the slope face. It is reported that the track is frequently tamped to maintain line and level. So GRCL’s scope also covers the reinstatement of the ballast shoulder and support to the cess, via the implementation of a lightweight cess support system.

Global Rail Construction are currently undertaking enabling works to prepare for their works prior the blockade. These works cover:

• Preparation of all related Risk Assessments, Works Package Plans, Task Briefing Sheets, Programmes and Methodology statements
• Supply, position and servicing all necessary, temporary fencing, office, welfare and ground protection for the compound on the wide payment/road

The Cess Wall Construction piling work will be commencing on 15^th February 2020 and there are two follow up possessions with engineering trains to complete the Cess Walkway in May and June 2020. Works cover:

Cess Wall Construction – Blockade

• Supply and Install 8m long steel sheet piles to construct approx 200m of cess walling, 3m from the nearest running rail on the Downline between the two LOC Staging.
• Temporary relocation and protection of the existing S&T cables

Cess Walkway

• Backfilling the existing cess walkway
• Laying a new Concrete Cable Route
• Relocating S&T cables into new troughs.

We are delighted to announce that Global Rail Construction Limited’s design team, have been awarded a contract with Alstom covering the GRIP 4 civils design for the Swinderby Resignalling Scheme. The design programme is now underway, with Scheme Plans and Level Crossing Ground Plans due to be submitted in July and the completion of GRIP 4 in September 2020.

The team have successfully supported Alstom on a number of schemes in the past, including the Design and Build civils programme for the East Notts Modular Resignalling Scheme GRIP 5-8 works, which covered eleven Level Crossings.

The Swinderby Resignalling Scheme comprises the Resignalling and Recontrol of the Swinderby Signalling area. It will include the conversion of 4 Level Crossings and the Renewal of Swinderby Road AHB to AHB- X.

GRCL’s GRIP 4 Civil Design works will cover:

Survey

• Non-intrusive site walkouts to areas of all works affected by scope
• Confirmation if any local services are required to be modified/rerouted
• Geotechnical Design/Ground Investigation report for all renewed/upgraded level crossings
• Geotechnical assessment surveys to reduce risk of unexpected ground conditions for new signal and locations.
• A Topographical survey of all renewed/upgraded level crossings, and a sample of REB’s, PSP, ASP, and new signal locations.
• IBJ Surveys
• Environmental/ecological surveys

Design

• Provision of a Design CRE for design authority sign off
• Civil design submissions (Forms 001/002 and 003)
• Design Certificates
• Details, calculations, drawings
• AFC Designs accepted
• Input into DRN responses
• Design Logs
• Designer Risk Assessments

The GRIP 4 design submissions for F001’s and F002’s will be grouped in accordance with the technical content i.e. signal bases will have their own submission, level crossing ground plans will have their own submission and at each design stage an IDC meeting will be carried out.

The design programme will be directed and managed from award to completion by the GRCL’s Design Manager. The Design Manager and Design team will be supported by Head Office resources. The team will be supported by a Ground Plan Designer, who will be embedded into the Civils Design Team. This will help to ensure that the ground plan AIP submission will have considered the necessary civils elements, eliminating the potential for issues that can occur when the design processes are separate.

Our UK Rail Infrastructure Contractor, Global Rail Construction Limited, has been awarded a further signalling civils contract with WS Atkins at Three Bridges Station. This latest project win is hot on the heels following their recent successful delivery for the same company, covering a platform extension and associated Civils and Track (P-Way) works at Redhill Station.

The work comprises the installation of a new cantilever signal superstructure and associated transfer grillage onto 410mm steel piled foundations, the relocation of signal T280 onto a new structure and the demolition of existing structure. The scope of works also covers the installation of RA offset signal structure and installation of a raised GRP platform for maintenance access. These works will provide the required signal sighting distance for normal and turnback operation of 12-car full length units (FLU) on Platform 1

This latest success follows the introduction of the new 8-car and 12-car Class for Train Operator GTR, being enhanced by Network Rail and is to support the requirement for providing the necessary signal sighting at Three Bridges, East Croydon, Brighton and Redhill railway stations.

The location of the new T280 signal is to be moved approximately 20.5m towards London from the centre bridge abutment to behind the London End abutment and wingwall. This will permit turn-back moves of FLU Thameslink Trains towards both London and country. An area of Network Rail land has been identified as the proposed location between the abutment and wingwall of underbridge VTB3/125. The abutment front wall is reinforced concrete faced with masonry and the wing wall is masonry with concrete fill to the rear. The ground signal T1192 located on the existing T280 signal gantry will be repositioned on a new post fixed to the base of the existing signal gantry which will remain in-situ once the gantry is removed.

The lines are powered by 750V D.C. conductor rails, which extend throughout the works area. There is an existing raised GRP walkway running parallel to the siding line which steps down to track level at the London side of the proposed structure. It is proposed to install a raised GRP platform butting up against the existing raised walkway for maintenance access. There are a large amount of surface cables running out of the existing cable trough, these will need to be managed prior to construction works.

Global Rail Construction’s works will include all necessary traffic management, materials logistics and works planning and site management and will be fully controlled by GRCL’s Southern based Contract Management team.

GRCL are delighted to announce the award of a Civils and E&P contract on behalf of long-term partner BAM, covering the completion of cable containment works between London Bridge and Cannon Street.

The full scope of this contract is to conclude residual works from the original Thameslink Key Output 2 (KO2), with the majority of the works being carried out in the central section inside Greater London.

The award supports the relocation of the DC feeders currently running down the West side of the Metropolitan Reversible Line between Metropolitan Junction and Cannon Street South Junction. The cables are currently surface laid and will be relocated into three newly installed GRP trough routes, by GRCL’s experienced railway civils team.

Running adjacent to the current location of the feeder cables is potentially an HV feeder cable(s) which will also require an HV assessment. This will be carried out before the main works under a line block using site warden protection. The conclusion of the resulting report may be the requirement for an HV competent person to be present during the works.

The Location of the works is in the cess to the West of the single reversible track Metropolitan Line, approximately between 01m40ch CSW to 01m45ch CSW. The Site will be accessed from Red Cross Way via the access steps between the Snowhill Lines and the Metropolitan Line. Outside of the main Week 39 works, a line block of the Metropolitan line will be required to safely access the work area.

Works will commence from 16th December 2019, when the materials will be delivered to Red Cross Way compound. During the main works, the bulk of the materials will be transported to Ewer Street RRAP and transported to the worksite using an RRV.

Global Rail Construction has been awarded a civils contract on behalf of WS Atkins, for a platform extension at Redhill Station.

The scope of works includes:

• Preparation of the existing platform for installation of a new modular platform extension
• Installation of a cable route through the platform
• Installation of new RA (Right Away) Indicator and concrete base
• All blockwork, tarmac and necessary works to existing copers
• Slotted sleeper installations and IBJ (Insulated Block Joints) recoveries and renewals

The project is being delivered on key weekends commencing in week 29 and also during mid-week nights.

This project is part of the new 8 and 12 car Class 700 programme for Train Operator GTR, being enhanced by Network Rail and is to support the requirement for providing the necessary signal sighting at Three Bridges, East Croydon, Brighton and Redhill railway stations.

The works will include all necessary logistics and planning management and will be fully controlled by GRCL’s project management team.

Our UK Rail business, Global Rail Construction Limited and Hedson Rail Limited have formed a strategic partnership, to successfully secure Phase 2 of the Track Delivery work bank on behalf of Network Rail’s Works Delivery team on the Wessex Route.
