LiDAR Survey System

Replicating the site digitally with precision LiDAR scanning,we deliver accurate, data-driven surveying.

Technology

LiDAR Survey System

Through a 3D precision surveying system combining drone and LiDAR technology, we quantitatively manage construction site quality. Linked with BIM-based structural drawings, the system automatically records survey data before, during, and after rebar placement, and analyzes it over time to improve both process accuracy and quality.

Key FunctionsFeatures

3D measurement and time-series analysis

Automatically stores 3D measurement data per concrete pour section using point cloud data from LiDAR sensors
Quantitatively identifies displacement, settlement, and construction deviation through time-series comparison of the same section
Combines drone footage to supplement quality inspection of blind spots hard to check by eye

BIM-linked quality management service

Provides a BIM-based 3D structural drawing link system to instantly compare actual construction status against design drawings
3D measurement data can be viewed via printout or tablet/smartphone digital viewer
Simulation during the framework stage automates schedule estimation and process review

Drone & LiDAR-based time-series analysis module

Automatically uploads periodic drone footage and LiDAR scan data for version-by-version history management
Acquires multiple data types such as ortho-photos, thermal images, and 3D point clouds to quantitatively compare process changes over time
Results are instantly notified to stakeholders, improving collaboration and verification efficiency

Data refinement and integrated management

Integrates, refines, and processes data collected from BIM, drones, and LiDAR in the cloud
Increases the usability of fragmented data to build an integrated on-site quality management system
Supports AI-based schedule estimation and automated quality document verification
