Challenges of Traditional Methods:

• Ground-based surveys require significant manpower, equipment and cost.
• Difficulty accessing elevated areas and intricate details (e.g., roofs, facades, tight corners).
• Dependence on fixed equipment such as total stations, which can be costly and inflexible.
• Limited ability to provide a comprehensive 3D overview of the project. 
• Design Validation Gaps – Difficulty comparing as-built structures with design/BIM models.
• Lack of high-resolution images capturing all fine details of buildings and infrastructure.
• Manual documentation may not provide reliable evidence during project handovers or disputes.
• Inefficient Earthwork Calculations – Cut-and-fill or stockpile measurements often lack precision.
• Challenges in sharing results remotely with developers, consultants, and investors.

With Drone Technology:

• High-resolution aerial mapping of residential, commercial, and infrastructure projects using RGB and/or LiDAR sensors.
• Land Surveying & Topographic Mapping – High-accuracy 2D orthomosaics, contour maps, and 3D terrain models.
• Digital Twin – Georeferenced 3D digital twins that enable BIM integration.
• Generating as-builts for as-built vs as-designed validation and clash detection.
• Site Planning – Pre-construction site survey, analysis, volumetric calculations.
• Construction Progress Monitoring through autonomous aerial updates to track project timelines.
• Streamlined collaboration through shareable 3D data.
• Detailed structural inspections, for example bridges, towers, and large infrastructure assets without scaffolding or downtime.
• Earthworks & Volume Calculations – Monitoring stockpiles, cut-and-fill operations, and accurate volume measurement.

• Enhanced on-site safety by identifying hazards and ensuring compliance with regulations.
