High-optical-zoom drone inspection of a critical stayed lattice radio mast — full structural condition report without interrupting live port communications.

Engineers With Drones used a confined space drone to inspect three derelict buildings — a bakery, a storage building, and a historic vat house — documenting structural condition without anyone entering the unsafe structures.

Engineers With Drones surveyed every roof on the Naas Hospital campus using a sub-250g C0 drone, delivering per-roof annotated condition reports organised by the contractor’s own building names.

Confined space drone inspection of three spillway interiors at Inniscarra Dam for ESB — capturing 4K video and still imagery of concrete conditions unseen since the 1950s.

Drone mapping of forestry on a mountain-side wind farm site in Clare, planned around turbine exclusion zones and delivered with a consistent point cloud and imagery record.

Engineers With Drones used a sub-250g C0 drone to inspect defective flashing across 70 housing estate units, delivering a per-unit report as a complete rectification work list.

Engineers With Drones captured high-resolution imagery of a 2km section of cliffside road at Mountain Stages, Kerry, replicating exact angles from a 2018 survey for a like-for-like comparison of coastal erosion and landslide activity.

Engineers With Drones captured 4K video and geotagged still imagery of a tidal flood defence barrage on the hour, every hour, throughout a full 12-hour tidal cycle.

Survey-grade photogrammetric mapping of 150 hectares for solar farm site assessment, with complete topographical data, orthophotos, and terrain models.

Confined space drone inspection of a 70-metre riveted steel stack critical to 24/7 production — internal inspection without human entry, shutdown, or cooling-down period.

Engineers With Drones carried out an ongoing underwater ROV inspection programme across most of the ESB's hydroelectric sites — inspecting critical infrastructure without divers or dewatering.

Engineers With Drones inspected seven buildings at a commercial shopping estate using a sub-250g C0 class drone, completing a full condition survey in a single day while the estate stayed open.

Engineers With Drones deployed an underwater ROV to inspect a live riveted steel penstock, expansion joint, inlet screens, and spiral casing without drain-down or diver entry.

Engineers With Drones used external 3D scanning and internal confined space drones to survey a derelict hospital building for restoration feasibility, without placing any personnel at risk.

Engineers With Drones combined drone technology, thermography and orthophotos to locate water ingress across 5.2 hectares of flat bitumen roof on a large commercial building.

Engineers With Drones used an ROV underwater drone to inspect anomalies in the Ardnacrusha head race canal identified by hydrological survey - historic infrastructure built in the 1920s.

Engineers With Drones surveyed four historic stone causeways in west Galway using photogrammetry to create high-resolution 3D models and technical deliverables.

Engineers With Drones used a high-optical-zoom drone to inspect a derelict crane at a Cork port terminal ahead of decommissioning.

Drone inspection of pier infrastructure at Belview Port — examining the underside of shore-side facilities using UAV technology to assess concrete defects and structural integrity safely.

Engineers With Drones used drone-based LiDAR and multispectral sensors to map large areas of farm land across Ireland, providing detailed information about farms and their carbon sequestration potential.

Engineers With Drones carried out a detailed drone inspection of a harbour pier wall, assessing hot-rolled interlocking steel sheet piles and concrete structure for defects and structural integrity.

Engineers With Drones carried out a detailed inspection of a large above-ground galvanised steel water tank used for fire suppression, using a confined space drone to access the interior.

Engineers With Drones used a confined space drone to inspect a large steel ethanol tank on a natural gas processing facility — eliminating the need for scaffolding or personnel entry.

Engineers With Drones surveyed 17 coastal sites across Ireland using drone technology to assess their potential as landfall sites for offshore cables.

Drone inspection of a 350-metre pedestrian bridge at the University of Limerick with an intricate cable-truss design that makes thorough manual inspection difficult.

Engineers With Drones used a drone to carry out a detailed inspection of pharmaceutical plant pipe racks, providing complete coverage of upper surfaces without the need for climbers or mobile elevating work platforms.
The above are case study articles of client work we performed - from project requirements, to how we approached it - and what we found. Some are inspections of structures where getting close safely was the main challenge. Others are survey projects where covering a large area quickly was the priority. We also feature underwater inspection case studies, where the drone was used to get an accurate view of the asset - without any need of divers.
If you are trying to figure out whether drone technology is the right fit for something you have in mind, we hope these help. You can learn about the challenges and deliverables for each type of drone survey or inspection. If you have any questions about the case studies or want to discuss a project of your own, please get in touch.
