The company carried out the surveying and marking out of the works, and supported logistics for plant and materials deliveries.
As part of the Sussex Region’s ongoing maintenance and renewals programme, Network Rail Works Delivery Unit (DU) engaged with Global Rail Construction Limited (GRCL) as their Principal Contractor to deliver a £100k contract for a critical sleeper renewal at Pratts Bridge near Eridge, East Sussex, 35m 1672yards.
The works required the removal of redundant 23nr PAN 8 sleepers and installation of new NRS1 base plated sleepers, ballast installation and tamping. The work was delivered as a package including planning, material management, logistics, survey and design validation, pre-works and engineering controls, delivery, and hand-back.
Global Rail Construction Ltd (GRCL) was awarded a £3m design and construct contract associated with eight existing and one totally new substation at West Ham on the Metropolitan & District Line. Having worked closely with the client at tender stage in support of their bid to LUL, GRCL fully project managed all aspects of the design and construction of the civil and building elements of the work. The existing substations were: Campbell Road, East Ham, Heathway, Hornchurch, Plaistow and Upminster Bridge.
In general, works at these substations were to strengthen and alter the existing buildings and structures to allow the positioning of new transformers, switchgear, cables and ancillary equipment or provide new bases, structures and building extensions to support and house the same.
Global Rail Construction Limited (GRCL) was awarded a multi-disciplinary contract on behalf of Atkins Global for the Civil and S&T installation works for a new level crossing at Sunningdale, which falls within Feltham Resignalling Phase 2.
The overall Feltham Resignalling Project covers the renewal of all signalling assets. Its area is covered by seven scheme plans, with delivery broken down into six separate Phases that align approximately to the Signalling Scheme Plan boundaries, Feltham ASC Signallers panels and Wokingham Signal Box.
Within the early advanced scope of Phase 2 was Sunningdale MCB-CCTV, which is subject to a full level crossing renewal – due for completion in November 2021. The scope encompasses life extension works with addition of barrier repositioning and narrowing of carriageway.
Global Rail Construction Limited (GRCL), has successfully completed a railway civil engineering design and build programme of works on behalf of partner Atkins Global, to support the upgrade the signalling systems in the Clacton-on-Sea area.
The Clacton Resignalling Projects’ principle driver was 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 dated back to 1958 and utilised a lever frame dating from 1891. There was a mixture of semaphore and colour-light signals, controlled by a mechanical/electro- mechanical lever frame. There was also a mechanical ground frame at Clacton Station. The existing signalling equipment has been previously subject of life extension works in both 1996 and 2004.
Many components were obsolete and only available on a repair and return basis. Most of the existing location cases had considerable corrosion. The signalling uses some single-cut circuits which are the subject of ORR concern. Searchlight signals were installed on this line, with known Wrong Side Failure (WSF) modes. P-Style relays in the lower portion of the box were recognised as susceptible to sliver migration. So, these works, will minimise maintenance and reduce whole life costs.
Global Rail Construction Limited (GRCL) has successfully completed the Design and Build of a Static VAR Compensator (SVC) Enclosure at Greenwich Generating Station. Under Power Upgrades Package 5C, Siemens, as Principal Contractor, appointed GRCL to deliver the project, to house the new SVC within a disused turbine hall.
Access to the substation was via the Old Woolwich Road, which was challenging. An internal substation access road was used for all construction logistics and deliveries with minimum disruption caused to the local residents.
Whilst on site, GRCL were awarded a variation to provide further civils installation works associated with the extension to the existing 22kV Switch room located on the 1st Floor of the Sub-Station. These works included the demolition of the existing wall, strengthening of the floor using steel support and concrete screed, blockwork walls, self-levelling screed, door installation and plinth foundations.
Global Rail Construction Limited (GRCL) has secured a multi-disciplinary S&T, Civils and E&P Points Heating remedial contract at London Bridge, on behalf of BAM Nuttall for the Thameslink Project.
As part of the Thameslink Programme, the railway systems for London Bridge were completely remodelled to suit a new layout at the Station and provide substantial capacity improvements to enable amendments to the operational timetabling – this is referred to as the N421 Project.
However, the complexity of managing, staging and delivering the railway systems in order to meet the remodelling programme, necessitated a requirement for the railway systems infrastructure to be surveyed, in order to confirm both its suitability and the requirements to undertake further upgrades and rectifications as required.
Global Rail Construction Limited are among a team of specialist rail contractors working in a highly coordinated manner to deliver these important upgrades for Network Rail. The in-house team of multi-disciplinary experts from Global, have worked almost entirely within a live, operational environment, interfacing daily with equipment that is switched on, in a wholly compliant manner.
The specialist discipline support services undertaken by Global Rail Construction Limited cover the entire end-to-end design and build scope of the Signalling, E&P and Ancillary Civil Engineering programme.
