Professional UAV Survey Services for Mining, Construction & Infrastructure
Merrett Survey Limited delivers professional commercial drone surveys for clients across mining, construction, infrastructure and engineering sectors. As part of our comprehensive topographical survey services, our CAA-approved drone operations enable us to capture high-resolution geospatial data across large or difficult-to-access sites, reducing project timescales and improving the accuracy of survey deliverables.
With almost 40 years of surveying expertise, our drone survey services are carried out by qualified surveyors who understand the data requirements of commercial projects. Every drone survey we undertake is planned, executed and processed by experienced professionals to ensure the deliverables meet the exacting standards your project demands.
Merrett Survey Limited provides professional drone survey solutions tailored to the specific requirements of commercial and industrial projects. Our qualified survey team operates across a range of sectors, deploying drone technology where it delivers the greatest value in terms of coverage, accuracy and efficiency.
Our commercial drone survey services include:
Our commercial drone survey services are deployed across a wide range of professional sectors. Every project is managed by experienced surveyors who understand the specific data requirements and regulatory considerations of each industry.
Drone surveys are particularly effective for mining and quarrying operations, where regular volumetric measurements, stockpile calculations and site progression mapping are essential. Our drone survey team works alongside our specialist mining surveys division to deliver accurate, repeatable datasets that support operational planning and compliance reporting.
From initial site appraisal through to as-built documentation, our commercial drone surveys provide construction and engineering teams with the aerial perspective and geospatial data needed at every stage of a project. We deliver orthomosaics, contour plans, cross-sections and 3D models that integrate directly with design software and BIM workflows.
Our drone survey services support infrastructure projects including highways, railways, pipelines and utility corridors. Drone-captured data enables efficient route planning, condition assessment and environmental monitoring across linear assets that would be time-consuming and costly to survey using traditional ground-based methods alone.
For oil and gas facilities, refineries and complex industrial plant, our drone surveys provide a safe method of capturing detailed imagery and measurement data without the need for scaffolding, rope access or confined space entry. This reduces project risk whilst delivering comprehensive survey data.
Our drone survey capabilities extend to coastal monitoring, erosion mapping, habitat surveys and environmental impact assessments. Drone-captured imagery and elevation data provides a cost-effective means of monitoring change over time across sensitive or difficult-to-access environments.
A commercial drone survey uses professional-grade unmanned aerial vehicles (UAVs) equipped with high-resolution cameras or LiDAR sensors to capture geospatial data for industrial, construction, mining and infrastructure projects. Unlike recreational drone photography, a commercial drone survey is planned and executed by qualified surveyors to deliver accurate, geo-referenced datasets that meet professional standards.
Commercial drone surveys are widely used across mining and quarrying, construction, infrastructure, oil and gas, utilities, coastal monitoring, environmental assessment and heritage documentation. Any sector that requires accurate aerial data capture over large or difficult-to-access areas can benefit from a professional drone survey.
When planned and executed by qualified surveyors with properly established ground control, commercial drone surveys can achieve horizontal and vertical accuracies of 20-50mm depending on flight altitude, camera specifications and ground conditions. Our team ensures that every survey meets the accuracy requirements specified for your project.
Commercial drone surveys are particularly effective for covering large areas quickly, capturing data in hazardous or inaccessible locations and providing a visual aerial record of a site. For many projects, we combine drone survey data with ground-based topographical surveys and laser scanning to provide the most comprehensive dataset possible.
All commercial drone operations in the UK must comply with Civil Aviation Authority (CAA) regulations. Our drone pilots hold the required certifications and all operations are conducted in accordance with current UK airspace rules, including obtaining any necessary permissions for flights in controlled airspace or near sensitive locations.
The duration of a commercial drone survey depends on the size and complexity of the site. A typical site of 5-10 hectares can be captured in a single day, with processed deliverables available within 5-10 working days. Larger or more complex sites may require multiple days of data capture.
