Using state-of-the-art software, our experienced surveyors complete a full assessment and testing of existing networks and identify requirements and unit counts. Using the captured data, our design team develops a detailed design in line with the client’s technical specification. During the survey and design stage, we innovate to create smarter solutions and invest heavily in programmes to drive improvements and efficiencies.
Four Bridges provides a complete aerial survey and aerial inspection solution. The use of cutting-edge Unmanned Aerial Vehicle (UAV/Drone) technology allows us to carry out aerial surveys to collect topographical data and imagery that is only possible from the air. From the resulting data, we can provide our client with precise geo-referenced data, stunning high-resolution photography, smooth video footage and a range of high quality 3D deliverables. This is a faster, safer and more cost-effective than traditional land survey methods. We can support real-time video links to our operators on the ground to enable instant decisions to be made. We are fully licenced to operate UAVs commercially by the Irish Aviation Authority and the UK Civil Aviation Authority, Italy and Austria. Our fully-trained UAV pilots are also experienced land surveyors.
Mobile mapping is the process of capturing geospatial data from a vehicle, it bridges the gap between terrestrial and aerial laser scanning. Four Bridges deploys the Mobile Mapping System to collect point cloud data and imagery of route corridors such as highway networks, railways systems and urban areas. From a vehicle the System can capture data while travelling at speeds of up to 70km per hour, often in a single pass. This highly-flexible 3D mobile mapping system can be mounted on almost any moving vehicle from cars, trolleys (e.g. railways) and boats. It comprises high definition 3D laser scanners and can achieve sub-centimetre accurate geo-referenced survey data. This data can be processed into CAD and GIS systems. The value of the data captures is enhanced through the inclusion of 360 degree imagery. This imagery combined with point cloud data captured by the laser scanner makes it possible to create 3D models.
Four Bridges has in-house design capability with a full in-house network design team. Actavo?s detailed network design provides all specifications, design drawings, costings and bills of materials required to proceed to the network build phase.
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 is responsible for the design and construction of the Metro network, the PoP and the design and construction of the access network, including the fibre drop to the home. Four Bridges has also carried out a number of design projects for Digicel in the Caribbean, including Guyana, Aruba, Dominica and Turks and Caicos.
