PROJECTS
Esholt Tunnel Bradford
This tunnel is almost 3 miles long and was constructed in 1920, 3200mm in diameter and serving the whole of Bradford we completed the survey in 1 go capturing Laser, Sonar and CCTV in 2015 and 2018
Northern Storm Water Interceptor
5 meter diameter interceptor over 5klm's through the center of Bristol, this is the longest survey undertaken with our 3D LiDAR unit in 2023
Mandeville Road Syphons London
MCallisters Group required a survey to plot the line and level on a syphon sewer under a railway line, this we did using our 3D LiDAR scanners and stitching the data to chambers scans. Resulting in accurate depths to the sewer under the track.
Bournemouth CIS
Wessex Water instructed Bright to undertake 8klms of surveying using both CCTV and 3D Lidar. The whole tunnel was surveyed over 10 days and captured line and level data, so repeat surveys can monitor movement over time.
Great Wirral Culvert
The Great Wirral Culvert was constructed in 1844, with the sole purpose to carry water from Wallasey Bridge to Birkenhead works. This asset had never been surveyed before, but it was stated a contractor once traversed it on a canoe. On completion we found half the asset was made up of brickwork and the other was tunneled through rock.
Wessex Water
Measuring the density in the material of a 3000mm diameter sewer on the Southern Foul Water interceptor in Bristol. Exposed re-bar clearly visible.
Suez Promenade Nice France
Suez required a full combined laser/sonar survey on 5 klms of trunk sewer along the main promenade in Nice, this was achieved over 4 shifts and the works were carried out in the evenings due to the bustling City Centre. A beautiful part of the world and the team had time to sample the local cuisine.
Ductile Iron - GRP Pressurised main
Bright were challenged with surveying a 1200mm Ductile Iron to glass reinforced pressurised main. We achived this by creating an access flange for our submersible sonar unit and feeding the winch line through a 6mm glande, which was bolted on top of the flange plate. Once the unit was inside the asset and the pumps were turned on, we were able to float all the way to the sea outfall which was 3.5 kilometres away. From the resulting data we produced accurate locations of the GRP line due to the step down in pipe size, and checked its ovality.
