Autonomous BIM Surveying

Autonomous BIM Surveying is a technology that uses LiDAR-equipped drones for real-time, autonomous collection and analysis of site data. This process continuously updates Building Information Models (BIM) with the current state of construction sites, enabling precise monitoring and management.

The technology addresses the challenge of maintaining accurate and up-to-date Building Information Models during construction projects by automating data collection and analysis processes.

LiDAR drones autonomously fly over construction sites to capture detailed point-cloud data. AI algorithms compare this data against the original CAD design to identify any deviations or changes in real-time. This information is then integrated into BIM models, providing a synchronized digital representation of the physical site's progress.

Manufacturing involves producing drones with LiDAR sensors, developing AI algorithms for data processing, and creating software to integrate drone data into BIM systems. This includes rigorous testing to ensure reliability and accuracy in various environmental conditions.

The build process begins with designing the drone's hardware, followed by integrating high-precision LiDAR sensors and AI software. The drones are then calibrated for specific environments before field deployment. Post-deployment, continuous updates and improvements to algorithms ensure optimal performance.

Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Drone operation requires significant power during flight but can be optimized through efficient battery use and solar charging options.

BIM (Building Information Modeling)

A digital representation of physical and functional characteristics of a facility. A shared knowledge resource for information about a facility spanning the lifecycle from planning to operations.

LiDAR

Light Detection and Ranging, a remote sensing technology that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth's surface, structures, etc. It can achieve high-resolution 3D mapping and surveying.

Drone

An unmanned aircraft used for various applications such as photography, videography, and now in construction site monitoring, equipped with advanced sensors like LiDAR for precise data collection.
