VGC contract value
£3.5 million

In 2006 Jackson Civil Engineering was engaged by NRTS (National Road Telecommunications Services) as part of its upgrade of the systems that link UK wide roadway communications devices (emergency telephone, CCTV, warning signs etc.). NRTS has the responsibility to upgrade, maintain and operate this vital network to ensure that the UK’s roads and motorways can run as safely and smoothly as possible.

The contract involved work along the M3 motorway between Junction 2 and Junction 9. VGC Construction was appointed by Jackson Civil Engineering to install underground service ducts along the length of the works in order to increase the capacity of the telecommunication links along the M3 corridor. VGC’s contract involved the supply and installation of over 50 miles of service ducts and cabling of various types. The ducting was typically a 4-way pipe configuration with associated chambers and cable management systems. Within the ducts VGC installed and tested the 24-way fibre optic and 40-pair copper cables. Where the new work interfaced with existing, the adjoining earlier ducting system required proving to ensure serviceability.

This demanding project was undertaken by VGC in close proximity to the open motorway. Managing the interface between the works and motorway traffic involved meticulous organisation of the plant and labour operations and careful coordination of material deliveries. By adopting a flexible and collaborative approach the ducting and cable installation was successfully completed to meet the timescales of the main contract.
