Northern Ireland Lake Survey

13/2/2025

0 Comments

 
Sometimes we are contacted by customers who have had a survey conducted by another surveyor, but for a variety of reasons it has not quite met their requirements. This was the case recently when we were asked to conduct a survey on a lake in Northern Ireland, to fill gaps in a previous survey conducted by another surveying team. The lake had been partly drained and the survey was required to help inform the client of volumes.
The client had appointed a local firm to undertake the works and, whilst the quality of what they managed to survey was perfectly adequate, they were unable to complete the full extent of the survey due to the margins of the lake being very soft and overgrown and thus unreachable. The parts below in Cyan were missing from the previous survey:

To infill these areas, we sent a team of three experienced surveyors including a trained boat skipper and trained drone pilot, equipped with total station, GNSS unit, laser scanner, survey grade drone, boat, sonar depth unit and 10m air track rafts to assist with access over soft ground.
Taking this amount of specialised equipment and trained team members meant that we could assess the viability of conducting a laser scan or drone survey based on the level of vegetation, visibility, ground conditions and weather, and assuming that neither would provide sufficient results we had the boat on stand by to survey the water line plus additional levels either side of the water line.
The trip duration was kept flexible, with a view to capturing the required areas by the quickest and most effective methods.
The results of the infill survey were added to the existing survey and reissued as a 3d topographic survey in autocad .dwg format.
