The National SCADA Tranche 3 project scope is to deliver an outline design, bill of quantities and cost of works, to provide additional optical cables required to maintain diverse communications to the outstations, in the electro-mechanical electrical control areas
Sunville Rail were contracted to survey, design and install SCADA fibre cable and the construction of lineside route works, including renovation of existing cable containment at the following sites:
•Sittingbourne – Sheerness
•Banstead – Carshalton
•Whyteleafe South Station – Purley
•Tadworth – Smitham
•Tolworth – Raynes Park
•Clapham – Earlsfield
•Strawberry Hill – Upper Halliford
•Branksome – Hamworthy
•Eastleigh – Eastleigh FTN
Robust planning was carried out to produce Work package plans, Safe work packs, Task briefings, HV assessments and delivery plans to deliver the works in the safest and most efficient way.
Over 60 km of Lineside surveys were carried out throughout the sites to determine the best route utilising existing and installation of new routes.
The main works consisted of vegetation and route clearance to allow for the installation of new routes consisting of concrete troughing, GRP post route, buried duct routes, route support, new joint bays, retaining walls and handrail.
Once the route works were installed the cable was delivered to site and hand pulled by the Sunville Rail team laying it into the new route or putting away in existing routes, the cable was pulled through station platforms, under track crossings and under road crossings and cable ends coiled in the joints or Telecoms buildings.
The cables were sheath gapped, jointed, terminated and tested.
Upon completion of route and cable installation Sunville Rail had to populate all results and handed back information to submit to the client.
This contract was successfully completed in July 2019.
