Four Bridges | Network Solutions has demonstrable experience in the planning, construction and upgrade of multiple networks within the telecoms, energy and water sectors. From making good existing networks to new network way-leaving, activation and commissioning, our systems ensure the quality, safety and environmental management of all our works is never compromised. This is demonstrated in our accreditation to ISO and OHSAS standards and being recipients of numerous major awards.
On behalf of Digicel, Four Bridges is currently building a 15,000km of Fibre-To-The-Home (FTTH) network across the Caribbean. The scope of work includes: survey, design, construction & commissioning, operation & maintenance. Four Bridges is responsible for procuring all fibre, electronics and any other materials required to complete the operating network. We procure bulk quantities of critical materials during the mobilisation phase, as well as procurement against Bills of Materials (BoMs) which are produced from the detailed designs. Four Bridges is providing all labour workforce, plant and equipment for the construction of the FTTH networks. The scope of work in the construction phase includes:
The networks being constructed are based on overhead ADSS (All Dielectric Self Supporting) fibre cable, which are mounted on existing poles belonging to the electric companies in each market. This is completed with the electricity networks remaining live wherever possible.
In April 2015, Four Bridges commenced the survey, design and construction of a new optical Fibre-To-The-Building (FTTB) network in Ireland on behalf of SIRO. The network is being built on existing ESB overhead and underground infrastructure. Four Bridges has been awarded 70,000 homes to date to construct across 4 towns ? Cavan, Dundalk, Mullingar, Newbridge, Naas, Johnstown, Kill, Sallin’s, Clane, Carlow and Navan.
In each town, the FTTH network consists of a metro (aggregation) network layer and an access layer (the PON) ? the layout of the network.
Network delivery at present is approximately 2,000 homes passed per month, which we deliver using a team of 90 people. The skillset across the team is diverse, covering project management, civils construction, overhead line construction, FTTB design, survey, wayleave office, fibre splicing/ testing and commissioning, quantity survey and quality control.
Four Bridges is responsible for the design and construction of the PoP stations and the design and construction of the access network, including the fibre drop to the home.
