Efficient Stockpile Volumetrics for House Builder
With delays from onsite contractors and disputes over slow progress, we provided weekly drone surveys for 20+ stockpiles and voids, delivering fast, independent cut/fill measurements in hazardous conditions.
Project Overview
Client Type: House Builder
Location: Manchester, UK
Services: Stockpile Volumetircs
Deliverables: Weekly Stockpile Cut/Fill Reports, High-Resolution Orthomosaic
Challenges
Disputes over slow progress:
Delays from onsite contractors led to slow remediation progress, affecting overall project timelines.
Hazardous site conditions:
The site was a quagmire after heavy rainfall, making traditional surveying methods unsafe.
Need for regular, independent data:
Client required up-to-date, independent data for more accurate project management and to resolve onsite contractor disputes.

Our Approach
Ground Control Network Setup:
To ensure survey-grade accuracy, we established a network of ground control points (GCPs) across the site. This provided precise geo-referencing of drone data for highly accurate measurements and mapping. This step is standard in all our stockpile, mapping, and topographic surveying services to ensure reliable data.
​
Weekly Drone Surveys:
We conducted 30-minute automated drone flights once a week, capturing repeatable high-resolution imagery and detailed 3D models.
Fast Processing and Reporting:
After each flight, we processed the collected data into a dense point cloud, orthomosaic, and digital terrain model. We then provided a final report detailing cut/fill measurements for the stockpiles, clearly overlayed onto the orthomosaic for visual reference, which was crucial for the client's remediation work.
​
Independent & Timely Data Delivery:
Our independent data offered objective insights, helping the client address disputes with contractors and keep the project moving forward.
Results & Outcomes
Faster decision-making:
Weekly, independent volumetric data helped track stockpile levels quickly and assign accountability where and when needed.
Reduced delays:
Faster data processing minimised project delays caused by onsite contractor disputes.
Accurate reporting:
Delivered precise cut/fill measurements in a fraction of the time compared to traditional methods.
Cost savings:
Eliminated the need for hazardous, manual surveys in unsafe conditions.
