DRONES FOR ENGINEERING inspectionS and ASSESSMENTS
The use of drones has proven to be a major time, energy, and money saver for both engineers and their clients. Useful for evaluating the exterior conditions of facilities, especially those in hard-to-reach spaces or locations, drones can provide fast, accurate, and detailed imagery for use in construction and engineering projects while conducting inspections that would previously have required human intervention.
Industries carry out regular inspections of their equipment and infrastructure to ensure it is in safe working order. Human inspections have shortcomings, as people are often limited when it comes to working at heights or in confined spaces. Inspections carried out by a drone can address the operational challenges faced by human inspections.
Excluding the need for expensive scaffolding, platforms and rope access, drones can significantly reduce the time and expense of industrial inspections when compared to conventional methods. Our drones are equipped with ultra-high-resolution cameras which allow for a close up, accurate view of a structure or mining quarry, even from a great distance.
Inspection of communication towers, buildings, silos, roofs, conveyors, flare stacks, wind turbines, buoys, and cranes.
Safe, accurate, and efficient aerial thermal imaging inspection and survey services require specialised high-end thermal cameras operated by experienced pilots. Our operators offer a comprehensive aerial thermal imaging service for asset inspection, surveying, and mapping using our industrial inspection system.
Building inspections (insulation), roof inspections (leaks), inspection of conveyors, power lines, silos, rail corridors, PV solar panels, and wind turbines.
Surveying, monitoring and reporting, drones are well equipped to survey developed and developing infrastructure, making them the perfect infrastructure project tool.
The low-flying capabilities of drones ensure the capture of precise and detailed data, thereby providing up-to-date and accurate information to support business endeavours such as site development and building refurbishment.
Aerial data for infrastructure assessments, aerial data for GIS applications, infrastructure assessments for insurance claims, geo-referenced high-resolution ortho-rectified imagery up to 1 cm GSD, high-resolution Google Earth overlays.
Having photos of various stages of a construction project can show the progress of the project as well as assist in planning activities. The generated maps highlight the location of structures, foundations, and services such as piping, plumbing and electrical systems.
Periodic aerial drone imagery to monitor site changes, geo-referenced high-resolution ortho-rectified imagery up to 1 cm GSD, high-resolution Google Earth overlays.
Using photogrammetry (a surveying and mapping technique), drones provide quick deployment and turn-around times with accurate reporting from point cloud datasets. Survey ground control, processing, and reporting tasks are carried out by our experienced and registered surveyors.
Uneven terrain can cause difficult and hazard working conditions for surveyors travelling over land on foot. Drones are able to quickly and precisely retrieve topographical maps of large areas with minimal wear and tear on equipment and low risk.
Predesign surveys for site planning, detailed surveys of existing infrastructure and topography, Digital Surface Models (DSM) and Digital Terrain Models (DTM), contour maps, accurate geo-referenced ortho-rectified imagery and maps, geo-referenced high-resolution orthophotos up to 1cm GSD.
Drone data can be used for drainage design plans for development sites. Data can also be used determine the best route for water to flow across a selected area.
High-density point cloud data for analysing terrain and flow patterns.
Accurate and detailed as-built drawings are essential to the success of modern-day construction projects. Drones can survey areas of interest to offer superior, speedy, and accurate data and models in the cost-effective manner.
As-built surveys for the quick collection of data for generation of 3D models, data acquisition for GIS applications, point cloud data acquisition of existing infrastructure for planning, accurate geo-referenced ortho-rectified imagery for generating CAD line drawings, high-resolution Google Earth overlays.
GPR is a non-destructive geophysical method that uses radar pulses to image the subsurface. Through electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, GPR detects the reflected signals from subsurface structures and has application in scanning pavements and structures.
Detection and mapping of utility lines such as water pipes, storm water pipes, sewer pipes and cables/cable conduits, detection and mapping of subsurface features.
Drones can efficiently and swiftly survey corridors (meaning pipelines, roads and servitudes) with quick turnaround times to create accurate surveys / models.
Mapping of small to medium scale areas, accurate Digital Surface Models (DSM) and Digital Terrain Models (DTM), contour generation, geo-referenced, high-resolution, ortho-rectified imagery with up to 1cm GSD.
The HydroLite-MB Multi-beam is a portable, bathymetric, dual frequency survey system. It has been designed as a turnkey, shallow water multi-beam rig, pre-installed and pre-calibrated on its mounting frame, useful in aquatic surveying.
Shallow water multi-beam surveys, depth sounding (sound velocity profiler), ultra-high resolution sonar, side scan imagery, identification of critical and dangerous objects on the harbour bed.
An automatic bathymetric drone catamaran capable of providing aquatic surveying.
Monitoring of various marine sites, generation of Sub-surface Digital Terrain Models (DTM).
LiDAR (Light Detection and Ranging) is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to objects. These light pulses – combined with other data – can be used to generate precise, three-dimensional information.
Airborne LiDAR survey involves the use of a LIDAR sensor to rapidly scan the environment using Laser and GPS technology, saving on time and costs.
Topographic surveys, accurate Digital Terrain Models (DTM) and Digital Surface Models (DSM) in areas with vegetation, engineering design surveys, corridor / strip surveys, slope monitoring, as-built surveys of existing infrastructure and architecture, accurate ortho-rectified imagery.
Terrestrial LiDAR (3D laser scanning) technologies provide 3D survey data that are accurate, dense and more economically produced than data from surveys using traditional techniques. This can be extremely useful in the documentation of structures such as oil and chemical refineries, highways, bridges and other complex structures, producing accurate ‘as-built’ drawings in very little time and with very little expense compared to traditional methods.
Topographical surveys, as-built surveys, engineering design and architecture surveys, monitoring.
