BALFRON PIPE BRIDGE
The Scottish Water pipe bridge crossing the A82 between Glasgow and Aberfoyle was struck by a truck causing major damage to the steel frame and structural integrity of seven pipes containing drinking water from Loch Katrine reservoir.
George Leslie – the main contractor for Scottish Water – approached Sigma Surveys to provide 24/7 monitoring of the pipes to ascertain whether or not any movement was occurring whilst the bridge was dismantled and rebuilt.
Trimble S8 total stations were set up and L-Bar prisms welded to the pipes so that monitoring could commence and provide accurate and consistent results over a prolonged period of time. The results were processed in realtime using Trimble’s T4D Control on a laptop in our HQ with GSM links streaming the data to our server for over a year.
Atkins were employed to design a new structure whilst keeping the pipes in situ during designs and construction whilst keeping the road open to the public for as long as possible. Sigma Surveys undertook a topographical survey of the bridge, road and surrounding fields to assist with designs. The bridge was also laser scanned with a Faro X330 laser scanner to produce an exact 3D pointcloud where plans, elevations and sections were produced of the bridge in its current condition.
During the project, Sigma Surveys provided George Leslie and Scottish Water with UHD video and hi-res images of the bridge structure through specific stages of the build from our DJI drone. A final set of images and video were produced on completion prior to the road opening to the public.
