What is AR floorplan capture for site surveys?

AR floorplan capture uses the camera and motion sensors on a smartphone or tablet to measure spaces and generate accurate digital floor plans as you walk around a building. The app overlays a real-time spatial grid onto the camera view, allowing the surveyor to mark corners, walls, doors, and windows by pointing at them rather than measuring manually.

The technology works by combining the device's LiDAR sensor (on supported hardware) or computer vision algorithms with accelerometer and gyroscope data to track position and calculate distances. As the surveyor walks the perimeter of each room, the app builds up the floor plan geometry in real time, displaying a live preview on screen.

Completed floor plans can be reviewed, edited, and annotated on the device before being synced to the SiteSurvey platform. Each plan is linked to the relevant project and property record, so it is immediately available to the wider team in the web portal. Plans can include room labels, dimensions, and equipment or asset markers.

AR floorplan capture is particularly valuable in sectors where accurate spatial data is required quickly and without specialist equipment. Building surveyors, FM teams, fit-out contractors, and healthcare estates teams all use the feature to reduce the time spent on measuring and to improve the consistency of data collected across different operatives.
