How it works on your site

The Exyn Technologies Nexys is a 3.1 kg modular LiDAR mapping sensor that captures 3D point clouds when mounted on drones, ground robots, vehicles, or carried by hand. It covers three documented subtasks within quality assurance and site safety: 3D scanning and point cloud capture, BIM-to-field comparison, and air quality monitoring via environmental sensing. Nexys has shipped since February 2024; construction is a secondary market for Exyn, with distribution through channel partners including KOREC (UK), Keystone Precision (US), Measur (Canada), and C.R. Kennedy (Australia).

Progress tracking & quality inspection

BIM-to-Field Comparison (Scan-vs-BIM)

A survey tech carries Nexys by hand or mounts it on a backpack or vehicle and walks the site in progress, and the unit returns a survey-grade point cloud with real-time results for change detection. The construction manager uploads that progress capture into the project BIM and compares as-built conditions with the planned state to catch deviations early.

3D Scanning and Point Cloud Capture

Nexys captures 360-degree point clouds using a gimballed LiDAR sensor at up to 1,920,000 points per second, outputting LAS, PLY, XYZ, and E57 formats. In autonomous aerial mode, the onboard SLAM engine navigates GPS-denied environments without pre-mapping or external communications. Scanning routes are programmable for repeat passes supporting digital twin workflows.

Safety & Environmental Monitoring

Air Quality and Dust Monitoring

Nexys integrates environmental sensors (gas, leak, gauge) alongside its LiDAR capture, collecting air quality data during routine mapping passes without requiring separate personnel entry into confined or hazardous spaces.
