Drone-based post-construction assessment and handover provides a highly accurate, visually rich, and verifiable record of completed infrastructure projects. Through as-built verification, drones capture high-resolution imagery and 3D models that are compared against original design blueprints or BIM files to confirm dimensional accuracy, detect deviations, and validate construction quality before final approval. This ensures compliance, accelerates quality checks, and reduces rework. For client handover documentation, drones generate comprehensive aerial photo sets, 4K videos, orthomosaics, and interactive 3D digital twins—creating a professional, audit-ready package that showcases the final project in its entirety. These deliverables provide clients with clear visual evidence of completion, support future maintenance planning, and enhance transparency. Combined, drone-enabled verification and documentation streamline the final stages of construction, improving communication, reducing delays, and delivering a superior handover experience.
Client Handover Documentation
Aerial Documentation & Digital Handover Packages
Overview
Drone-based client handover documentation provides a complete visual and spatial record of project completion.Aerial imagery, videos, and 3D models capture the finished site in remarkable detail, forming part of the final deliverables to clients, investors, or regulatory authorities. This creates a permanent, audit-ready, and visually rich record showcasing the quality, scale, and accuracy of the completed infrastructure.

As-Built Verification
As-Built Verification & Design Validation using Drones
Overview
As-built verification ensures that a constructed structure precisely matches its design specifications. High-resolution drone imagery and 3D modeling allow engineers and project managers to compare actual site conditions with CAD or BIM blueprints. This digital validation process identifies deviations, dimensional mismatches, and missing components early—enabling faster rectification, accurate billing, and quality assurance before handover.
