Route Survey, Installation, Jointing, Commissioning and Testing of ductwork and fibre optic cables in the London Sewer System and in the Highway

J Browne Construction was awarded this contract to install fibre optic cables across London, primarily using the Thames Water sewer system, but also in the highway using open cut and ‘no-dig’ solutions to connect point-to-point. The works are based on ICE Minor Works 3rd Edition with each cable route being let as an individual contract within the framework.

J Browne has been able to add value to the service offering of the Client through our expert knowledge of Thames Water and their sewer assets. This knowledge has enabled us to install the fibre optic services with the minimum of disruption to the highway network and provide a more cost effective solution for the end users of the networks.

We provide a full service to our Client from arranging closures and noticing under the Traffic Management Act (TMA), liaising with building owners to carry out surveys and breakthroughs  in to their buildings, route surveying both in the sewers and the highway, the installation, jointing, testing and commissioning of ducting and fibre optics cables. To date we have installed 11.5 km of fibre optic cables across London.

Our highly trained teams all have experience of working on the Thames Water Sewer networks. This challenging environment requires substantial planning to ensure it is carried out safely. All our personnel are confined spaces trained and our systems include for the monitoring of weather and rainfall which can produce flash floods in the sewer network.

J Browne recently connected into a major Data Centre on London’s South Bank. With a 2 km sewer installation, this latest network development through the sewers in London will enable companies around London Bridge to benefit from faster and more efficient connectivity. The fibre optic network has capacities up to 10 Gbps as well as dedicated point-to-point fibre, providing customers with a more flexible approach to managing their growing bandwidth requirements.
