UAV Inspection & Surveying Service
As part of Zenith’s expanding portfolio of services, we are pleased to provide our clients with our PfCO CAA licensed UAV Inspection and Surveying Service carried out by our team of 7 qualified pilots.
We are able to generate 2D and 3D models from captured survey information and existing drawings. We can accurately determine revised capacities and assess the life extensions of existing structures and structural elements.
Decay, loss of section, material properties, geometry and change of use are a number of variables that can affect the performance and life span of any building or structure. This can all be modelled to represent a snapshot in time and assist with determining the structural integrity of existing assets.
A UAV inspection allows for a visual examination of structures providing photographic and video records. Following the survey, a comprehensive report is compiled by our dedicated team of Structural Engineers. UAV inspections allow engineers to identify and assess the general condition of the structure. This combined with Zenith’s hands on survey capability offers clients a full suite of inspection services.
Our UAS platforms can be tailored to suit the prospective operation, whether it be for extended flight duration, thermography, high definition photo or video imagery.
Visual Survey
Using our 30x optical zoom camera we can capture detailed close-up video and still imagery, even when the survey environment does not allow us to fly close to the subject, such as operational flare tips and chimneys. Ideal for condition surveys and defect identification on buildings and elevated structures.
- Flare tip condition surveys
- Cooling tower and chimney condition surveys
- Roof and gutter inspections
- Jetty inspections
Our high-resolution cameras are capable of 20Mp images and up to 5.2k definition video for high quality media for project highlights and marketing.
Thermographic Survey
Our thermal camera uses a specialized FLIR Tau 2 thermal sensor and a 4K visual camera along with image processors to render the results on a visual display. We have the capability to interrogate and interpret the survey data to identify temperature differentials and defects.
- Insulation defects
- Moisture ingress
- Building heat loss
Orthomosaic and 3D Point Cloud
We can create high resolution orthomosaic images and 3D models of sites and structures by collecting a large number of individual overlapping photographs and processing them using specialised orthorectification software.
- Site plans and construction progress
- Surveying/measurements
- Asset identification and virtual survey
Topographic Survey and Volumetric Measurements
3D point clouds can be further developed and interrogated using specialist software to produce topographic (contour) maps and surfaces. Surfaces can be compared to enable volumetric calculations.
- Site plan
- Stockpile measurement
ROV Survey
Zenith also own an ROV for underwater inspections providing photo and video images.
- Hydro scheme inspections
- Jetty inspections
