Cut and fill analysis
Avoid costly construction delays with super-accurate earthwork volumetric measurements. Drones give you the most precise and convenient way to calculate cut-and-fill ratios.
Let's talkAvoid costly construction delays with super-accurate earthwork volumetric measurements. Drones give you the most precise and convenient way to calculate cut-and-fill ratios.
Let's talkThere is no room for error when calculating cut-and-fill measurements. Excavating too much (or too little) results in increased labour costs and delayed work. Drones are a precise and efficient way to calculate cut-and-fill ratios without affecting your schedule. Engineers With Drones complete measurements for you faster than the traditional methods, while simultaneously streamlining your project.
Monitor earthwork changes over time for a fast and cost-effective way to avoid any discrepancies.
Get quick and precise readings on cut-and-fill measurements, allowing for seamless tracking and future ordering.
Record and document terrain more accurately, regardless of its elevation differences or vegetation density.
Record and compare your volume measurements over time, more cost-efficiently and with fewer man-hours.
Receive instant and actionable data relating to your loose, bank, and soil volumes.
Find all anomalies and potential problems that might otherwise go undetected.
At its core, cut and fill analysis is the comparison of two digital terrain surfaces. The drone captures a survey-grade 3D model of the site before work begins. After excavation, grading, or filling, a second survey captures the new surface. The processing software overlays the two models and calculates the volume difference at every point on the grid — producing a colour-coded map that shows exactly where material has been removed and where it has been placed.
What is the difference between a DSM and a DTM, and why does it matter for earthworks?
A digital surface model (DSM) includes everything on the ground — stockpiles, vegetation, buildings, machinery. A digital terrain model (DTM) represents the bare earth with all surface features removed. Both are generated from the same survey data: the DSM captures what the drone sees, and the DTM is produced by classifying and filtering out non-ground points.
For earthworks, the distinction is critical. If you compare a pre-construction DSM (with trees and undergrowth) against a post-excavation DSM (bare soil), the volume difference includes the vegetation you cleared — not just the soil you moved. Comparing DTM against DTM gives you the true cut and fill volumes of the earth itself, which is what your quantity surveyor and contractor need for payment and planning.
More about LiDAR and terrain modellingWhat does an elevation heatmap tell me that a site photograph does not?
A site photograph can be misleading. Shadows, vegetation, and lighting conditions can hide slope angles and elevation changes. An elevation heatmap replaces colour with absolute height data — every pixel has a known Z-value — so slopes, depressions, and drainage paths are unambiguous.
For earthworks planning, this is particularly useful for identifying the natural drainage corridors before you move any material, verifying that finished gradients meet design specifications, and locating low points where water will pool after grading. The heatmap turns topography into a measurable dataset rather than something interpreted by eye from a photograph.
Discuss cut and fill analysis for your project
We use cutting-edge technologies to detect problems that would otherwise be invisible. These include 4K ultra-HD photography/video, LIDAR and thermal imaging.
Drones aren't just for flying up in the sky. Our specialist drones can fly into confined spaces like chimneys and boilers to look for issues that would otherwise be inaccessible.
Downtime is expensive and inconvenient. Using a drone, our engineers can conduct a thorough survey with little to no downtime.
Our equipment won't touch or even go close to your assets. Our high-resolution cameras use optical zoom to give extreme close-up views while staying a safe distance away.
We understand that you need answers fast. We can deliver a plain-English report with clear-cut conclusions in days. Then, you can take the steps you need to and get back to doing what you do best.
Need us there in a hurry? No problem. Let us know what you need, and we can be there on the same day. After all, sometimes the problem just won't wait.
Sometimes the brief can change even in real-time. If need be, you can be stood there right next to the drone operator, directing them as the situation develops.
The safety of your personnel and our own is paramount, and we place it at the forefront of our company culture. Ask us about our HSSE systems and practices.
Cut and fill analysis is incredibly versatile, and we use it in various types of inspections serving multiple industries.
Engineers With Drones is the first company in Ireland to hold the new EASA Specific Category authorisation. We are authorised by the Irish Aviation Authority (IAA) and the European Union Aviation Safety Agency (EASA) for commercial Unmanned Aerial Vehicle (UAV) operations in both urban and rural environments. Total transparency: our Specific Category Authorisation Number is IRL.UAS.AUTH1002.
All of our operations are insured in the EU and globally. We hold €6.5m public and product liability, €13m employer's liability and €1.3m professional indemnity (base level, coverage raised as required).
We are more than just drone pilots. If you're looking for overhead footage of your wedding reception, we're probably not right for you. Our backgrounds and our primary qualifications are in engineering, and it's here that we think we add the most value. We know what we're looking for, and we know how to find it. If you have a technical engineering problem that a drone can solve, we can understand you. Tell us what you need to see or find out, and our engineers will use their drone piloting skills to make it happen.
Yes. We're a local Irish company, and that's how we can respond so quickly to the needs of our Irish clients. We can be with you in next to no time, with the right equipment and certifications to operate them, whatever your location.
Optical zoom is a feature found in cameras that allows you to change the focal-length of the lens, which in turn magnifies the image. Unlike digital zoom, which simply enlarges the pixels of an image, optical zoom physically moves the lens elements to zoom in or out, resulting in a higher-quality, more detailed image.
Optical zoom is better than digital zoom for several reasons. Firstly, optical zoom maintains the image quality and sharpness because it captures more detail from the subject. In contrast, digital zoom often results in a pixelated, blurry image because it enlarges the existing pixels of an image, which degrades the quality.
Secondly, optical zoom allows you to get closer to your subject without physically moving closer, which can be useful in situations where you cannot or do not want to approach your subject closely. This can be especially helpful for wildlife photography or for taking photos of events from a distance.
Overall, optical zoom is a valuable feature that can help you capture high-quality, detailed images from a distance, making it a must-have for many photographers.
UHD or Ultra High Definition signifies that a camera's resolution is 3840x2160 pixels. This is exactly four time higher than high definition cameras (1920x1080 pixels), and so UHD is often also know as 4K.
