Quarry, landfill or earthwork surveys can be carried out with a drone survey
quickly, cheaply and safely without the risk of trips, falls, spills and collisions
A drone earthworks survey can delivers volumes calculations in hours not weeks
Earthwork volume calculations are often performed in the field by land surveyors or civil engineers. Earthworks surveys are needed to calculate the volume of earthworks for a given project. Earthworks surveys are often repeated and volume calculations are compared over time. This can be done in two ways:
– by surveying the area and calculating the volumes of earthworks or stockpiles with a drone land survey using photogrammetry or lidar survey data
– by surveying the area and taking measurements from a topographical survey using traditional land survey equipment and calculating volumes from that data.
Stockpile volume calculations from drone survey data
Traditional volume surveys happen at a snail’s pace compared to a drone volumetric survey.
Traditional Land Surveying is relatively time-consuming, expensive, and requires a lot of manpower to be carried out successfully. A Land Surveyor walks the whole site recording the 3d position of coded points. This poses several health and safety risks that a drone survey can mitigate.
Features are mapped, a triangle terrain model is produced and contours are extracted. Stockpile volumes and earthwork volumes can then be calculated based on that digital terrain model. Sequential comparisons with restoration levels, design levels, and erosion or deposition patterns can be accurately compared over time. Each survey could take days to survey and process. Repeat visits could be quite a drawn-out process.
Ground-based laser scanning is much quicker than a traditional survey but still poses all of the same health and safety risks and would take hours to measure. Mobile mapping with a handheld laser scanner would be quicker still. All ground-based methods would have gaps in the data because of line-of-sight issues. More observations, stations and scan points would over come this at the expense of time.
A drone survey is far, far quicker.
Measuring volumes with a drone is safer, quicker and more cost-effective
In order to make data collection more rapid safer and more cost-effective, drones are being used as an alternative option for surveying purposes. Survey-grade data is rapidly collected across a whole site in a much smaller time frame. A traditional survey would often involve repeat visits every few weeks to help accurately monitor how much material has been moved on and off-site. By using a drone data collection is much quicker. A drone can cover far larger areas with less risk of personnel injury on difficult terrain from falls or machinery. By reducing the time frame of data collection it is possible to increase the frequency of surveys. Often tracking changes in near real-time. Reducing the interval allows more for accurate tracking of changes and less estimation between surveys.

Drone deliverables are also better
Each visit provides an orthographic photograph or a 3d photorealistic model of the whole site as well as a topographical survey and volume report. A rapid Lidar Survey with a drone can yield almost instant answers with very little processing time compared to photogrammetry. Both photogrammetry and Lidar are quicker than a traditional volumetric survey and produce tight point cloud data of the survey area. A traditional survey inevitably has an element of estimation but a skilled land surveyor chooses their survey points wisely to maximize the accuracy of the digital terrain model. Even so, points between the survey points are interpolated on a traditional survey. With a drone survey, every nook and cranny is measured removing much of the guesswork for a surveyor. Our skilled and experienced surveyors can make sure the survey accurately reflects the real-world terrain. Ensuring accurate volume calculations. Errors in the data collected and the model produced can make huge costly differences. Frequent shorter survey times allow for rates of movement as well as volumes to be accurately monitored, supplementing your normal weigh bridge with more qualitative and quantitative data. Ultimately, a drone mapping survey can deliver a 3d model or digital twin of both the terrain and physical assets on site.

Volume surveys: FAQs
A volumetric survey is a specialized type of land survey that focuses on measuring volumes, such as earthworks, stockpiles, or water bodies. It is essential for various projects, including construction, mining, agriculture, and environmental management, as it provides accurate information for resource allocation, planning, and monitoring.
The cost of a volumetric survey depends on factors like the project size, its complexity and the frequency of the surveys needed. We will aim to give you a bespoke quote for your project. If you manage several sites this can also have a bearing on the price.
The accuracy of volume measurements in a survey can be affected by the surveying method, equipment used, terrain, and weather conditions. As skilled surveyors, we will minimize these factors by employing appropriate techniques and technology. Sometimes we will use multiple types of equipment to carry out an accurate survey. Predominantly this will be with a drone as the most comprehensive and repeatable method of gathering data safely and very quickly.
Volumetric surveys are commonly used in industries like construction, mining, agriculture, environmental management, and waste disposal. They help with tasks like calculating earthwork volumes, measuring stockpiles, managing landfills, and determining water storage capacity.
The time required to complete a volumetric survey depends on the project’s size and complexity.
Using traditional ground surveys, smaller projects may take a few days, while larger or more complex projects could take weeks.
With a drone volume calculation survey, with photogrammetry, a volume survey would be completed in less than a couple of hours even on a large site. Data processing of the images with take some time but is still considerably shorter than a traditional survey.
A lidar volumes survey with a drone would take the same amount of time to fly but the results would be available on-site within minutes for initial calculations and the full results a day or so later.
Key considerations when commissioning a surveyor for volume calculations include their experience, qualifications, use of modern equipment and technology, and understanding of your project’s specific requirements.
Volumetric surveys often utilize advanced equipment and technology, such as GPS, 3D laser scanning, aerial photogrammetry, and drone mapping, to ensure accurate measurements and detailed data.
A volumes survey can help optimize earthwork and material management by providing precise volume calculations. This information enables better resource allocation, cost estimation, and project planning.
After a volumetric survey, you should expect a detailed report that includes the volume calculations, methodology, data, and visuals (e.g., maps, charts, or 3D models). This report will be crucial for informed decision-making and project management.
No. Even small sites can have a need for volume calcs. For example, the survey below was about potential planning enforcement on a site where material had been imported. Sections through the site compared to historical data show the amount of fill.
