What positional accuracy can you achieve?

With ground control points, centimeter-level absolute accuracy is achievable. Without GCPs, accuracy depends on the project's accepted tolerance.

Repeating drone orthomosaic capture of an active construction site for progress monitoring, timeline comparison, and stakeholder reporting

Core Service

Aerial Construction Progress Monitoring

Recurring high-precision drone mapping of your construction site. Orthomosaics, 3D models, and timeline comparisons that keep stakeholders aligned.

Overview

Managing a large construction site requires constant oversight. Holmes and Watson provides recurring aerial data capture — weekly or monthly — delivering updated orthomosaic maps, 3D site meshes, and progress photos with consistent ground control. The result is an indisputable visual record of site conditions, easier subcontractor management, and remote stakeholders who actually understand what's happening on the ground. (Looking for owner-facing third-party verification with licensed-contractor review? See Commercial Job Site Progress Inspections.)

Why Choose Drone Construction Progress Monitoring

Recurring drone mapping with consistent GCPs produces a survey-grade record of every milestone. Stakeholders who can't visit site weekly can review the cloud-hosted timeline whenever they need to.

When to use it: Use construction progress monitoring for any project where consistent visual documentation supports schedule, dispute avoidance, or stakeholder reporting needs.
