Global Rail Construction Limited has secured a Points Heating remedial contract with BAM on the Thameslink Project. The E&P design and build package of works, forms part of a requirement to upgrade and rectify the railway systems infrastructure to support the capacity improvements recently made in the London Bridge area.

The 26-week programme, includes an 8-week procurement period in order to secure all necessary RCM equipment and parts for the project and covers the following activities:

• Preparatory investigation and surveying including:
  • A detailed review of as-built records
  • Reviewing and assessing of current designs
  • Correlation of the RCM installation

• Design works which covers:
  • Collation of survey data to determine the scope
  • Civils design
  • E&P design

• Installation works:
  • Civil Engineering works
    • Installation of TX Bases
  • Electrical works
    • Cabling, Jointing and termination works
  • PHCC/RCM Remedial works and commissioning
    • Removal and replacement of CT boards
    • Mechanical fixing and installation of new CT’s
    • Installation of new Aerials
    • Installation of new circuitry (MCB’s, CT’s, Terminals, Labels)
    • Installation of DCU 390 PH – Data Loggers
    • Environmental testing (Hot & Cold Probes)
  • Commissioning, configuration checking and final testing

• The provision of as-built information including O&M data

The 6-week design and survey period commenced this month, with the remainder of the contract works being completed by late September 2020. Installation works will be undertaken during a standard 5-day working week and activities will be worked concurrently in order to meet the required project milestones.

Mechanical & electrical services provided by Global Rail Construction are constantly upgraded through training and development and are consistently delivered to the highest specification.

Design and project management of these specialist services are deployed on projects such as sub-station refurbishment and new build, station refurbishment and new build, signalling equipment room fit-outs, station platforms and car park lighting.

As part of the Thameslink Programme, the railway systems for London Bridge was completely remodelled to suit a new layout at London Bridge station and provide substantial capacity improvements to enable proposed current and future operational timetabling, this is referred to as the N421 Project.

The complexity of managing, staging and delivering the railway systems in order to meet the remodelling programme, has necessitated a requirement for the railway systems infrastructure to be surveyed, in order to confirm its suitability and whether further upgrades and rectifications will be required.

To support these works, Global Rail Construction Limited (GRCL) has been awarded a lineside survey contract by long-term customer BAM Nuttall, to undertake the necessary investigation and reporting of 44No Signal Gantries and their associated containment, which includes but is not limited to the following scope:

1. Structural condition surveys in relation to original Form A requirement for painting
2. The condition and positioning of cables on the structures including
   1. The position of cables relative to associated tray work/containment (particularly noting areas where cables have no associated containment)
   2. The type of signal cable (B or C)
   3. An assessment of cable slack (or tension)
   4. Any visible damage to cables
   5. Any serrated edges on tray work/containment that could potentially cause damage to cables
   6. Any structure concerns
   7. Tagging and tracing of cables to ensure end to end point identification
   8. Condition and suitability of the use of cable management to secure cables to containment in contrast to the existing Civils As-Built design

On completion of each survey GRCL will review and discuss the photos and observations with the BAM team at a weekly Technical Interface Meeting and determine one of the following:

1. An agreed scope of residual works (with no further survey requirements) or,
2. The requirement for further detailed ‘tag and trace’ surveys

GRCL will produce final survey reports, documenting the findings, associated agreements and will include any recommended remedial works to be undertaken, whereby GRCL can be instructed to complete the remedial scope.

Project Manager Barry Smith, is leading Global Rail Construction Limited’s in-house team of self-delivery experts, who will be covering all disciplines including Civil & Structural Engineering, Signalling and E&P.

Surveys are already underway and there are a number of Signal Gantries already completed, some remedial works instructed and on-going, with further awaiting instruction shortly.

MD Marco Lombardelli added this:

“Delighted to be awarded this multi-disciplinary package of works from our esteemed client BAM. The full suite of internal expertise will be managed and delivered by our in-house staff, something that we are immensely proud of.”

Global Rail Construction Limited (GRCL), has been awarded a railway civil engineering design and build programme of works on behalf of Atkins Global. Clacton Re-signalling’s principal driver is the asset condition of the interlocking and associated track infrastructure at the throat of Clacton-On-Sea station.

Much of the signalling in the area dates back to 1958 and utilises a lever frame dating from 1891. There is currently a mixture of semaphore and colour-light signals, controlled by a mechanical/electro- mechanical lever frame. There is also a mechanical ground frame at Clacton Station. The existing signalling equipment has been the subject of life extension works in 1996 and 2004.

Many components are obsolete and only available on a repair and return basis. Most of the existing location cases have considerable corrosion. The signalling uses some single-cut circuits which are the subject of ORR concern. Searchlight signals are installed on this line, with known Wrong Side Failure (WSF) modes. P-Style relays in the lower portion of the box have been recognised as susceptible to sliver migration. So these works, will look to minimise maintenance and reduce whole life costs.

GRCL’s civil engineering contract covers the provision of a full site-setup, all necessary management and supervision, materials, plant and delivery to the point of construction. The scope consists of the following elements:

• Vegetation clearance
• Design and Build of 1No Location Staging Platform
• Design and Build of 11No Signal Foundations (mixture of concrete and piled solutions)
• The installation of other ancillary railway civils including location hardstanding’s, RRAP’s, cable routes and a Relocatable Equipment Building foundation base and associated works (Design by Atkins)
• Site Clearance and Waste Recovery throughout construction and upon completion

Managing Director, Marco Lombardelli added:

“This is a fantastic award for the UK team.

“Utilising our railway design and construction capabilities in civil and structural engineering, we look forward to the successful completion of these important works, in order to upgrade the signalling systems in the Clacton-on-Sea area.

“This is another collaboration with our partner Atkins Global, and we look forward to many more.”

We are pleased to announce that Global Rail Construction Limited (GRCL), has been successful with its tender for the Designer Tier 2 Framework Agreement with BAM.

The design team provided a compelling offer, evidencing the following:

• How safe design and specifying has been previously achieved on its projects;
• The organisation’s in-house design and railway engineering capacity;
• How engineering assurance has been applied to previous projects;
• How digital approaches are integrated into its work;

GRCL also provided some initiatives in relation to provisions for diversity and inclusion across the business and some working examples of how inclusivity has made a difference.

The contract will extend throughout Network Rail’s Control Period 6 (CP6), covering BAM’s Southern Multi-Disciplinary (SMD) Framework and GRCL will be providing Design services on a call off basis for a five-year period.

Delighted GRCL Design Manager, Richard Horsted added:

“This is great news and testament to the efforts of the entire team. We have made impressive strides with our design and consultancy development recently, and this latest success is reward for the fruits of our labour.”
