Accurate volume calculations, drainage design from real terrain data, and an objective programme record — this guide makes the commercial case for drone survey on UK earthworks and infrastructure projects, with a focus on what it means for QSs and PMs.

A drone survey captures a complete aerial dataset over a site — topographic models, volume calculations, and orthophotos — faster and more safely than ground-based methods alone. This guide explains how it works, when it makes sense, and what the deliverables look like on a UK construction project.
