S-PRO’s role was to make sure the right problem was being solved by the right team. After assessing the client’s requirements, S-PRO coordinated with Etijah, who defined the tech stack and provided core expertise in geospatial data, computer vision, and construction technology. This collaboration led to the selection of Postdata, who built the platform through a structured engagement that moved from discovery to a production-ready product.

Construction AI: Automated Progress Detection
The AI engine analyzes drone orthomosaics against design plans and estimates completion at both the project level and for individual components. Each estimate includes a confidence score and specific evidence from the imagery: what was expected versus what was observed.
When a new flight is uploaded and processed, the AI generates a detailed report within minutes. Project managers see which components are progressing, which are behind, and where the current site diverges from the design plan. The next phase will add warnings for data quality issues – shadows, obstructions, or plan-versus-site mismatches – so teams know how much to trust each estimate.
2D/3D Visualization and Measurement
Drone data is processed into interactive orthomosaics and 3D point clouds viewable directly in the browser. Built-in tools handle distance, area, and earthwork volume measurements without external CAD or GIS software.
A comparison mode lets users view two drone flights side by side with synchronized navigation. CAD overlays allow design drawings to be placed on top of drone imagery with adjustable opacity, so teams can check whether construction matches the plans.

Flight Management and Data Processing
The platform handles the full drone data lifecycle: upload, automated processing through OpenDroneMap, and generation of orthophotos, point clouds, surface models, and reports. Teams upload raw flight imagery and receive processed outputs inside the platform – no manual file management or third-party processing tools.
Project Management and Collaboration
Work is organized into projects, phases, and milestones, with budget tracking, role-based access control, and status flags for on-track, ahead, and delayed projects. Annotations let team members pin observations to the 3D model or 2D map, flag issues, and assign follow-ups.
An executive dashboard gives leadership a portfolio-wide view: status distribution, progress trends, budget utilization, and a map of every active site.
