Drone Surveying addresses the challenges housebuilders face in maintaining accurate earthworks and materials management.

Traditional, manual surveys provide only a partial picture of onsite materials, making it difficult to implement the materials management plan (MMP) effectively.

Inaccurate volume calculations lead to costly over- or underordering of aggregates, inefficient reuse of materials, and compliance challenges with environmental regulations. These risks are exacerbated on large developments, which often comprise hundreds of plots.

Drone Surveying – as the name suggests – provides a digital, drone-based survey and consultancy service that uses photogrammetry and a secure online portal to capture, analyse and manage earthworks data.

Each drone flight collects high-density survey data across the whole site. This is processed into an accurate digital terrain model and orthomosaic imagery, then run through a volumetric analysis workflow to calculate the volume of every accessible stockpile.

Drone Surveying’s in-house engineers enrich the dataset, naming and categorising each stockpile (eg topsoil, subsoil), tagging location and intended use, and aligning outputs with the client’s MMP. This provides a clear, auditable record of materials and supports planning and environmental compliance.

Visual reports and CAD files are generated and shared via an online portal, enabling site, commercial and technical teams to monitor progress, track earth movements and make decisions based on current, measured data rather than estimates.

Among Drone Surveying’s housebuilder clients, stockpile measurements are now accurate to within ±2%, compared with manual survey tolerances of up to ±15%. Survey turnaround has been reduced from several days to under 24 hours, giving near real-time visibility of earthworks progress and enabling faster approvals, valuations and change control.

Drone Surveying’s customers also report improved confidence in materials quantities, delivering cost savings of up to 20% in aggregate management and haulage. Drone data collection also removes the need for operatives to climb or walk stockpiles, reducing exposure to slips, trips and vehicle movements.

Clear records of surveys, volumes and stockpile histories provide robust evidence for CDM duties and planning conditions, supporting both safety governance and regulatory compliance.
