Overview

An architecture firm required our services to provide accurate data to support their upcoming facade renovation project for St. Elizabeth Retirement Residence. We provided our Scan-to-BIM services to capture the exterior of the 7-story building, located in Hamilton, Ontario.

‍

On-Site Data Acquisition

Our comprehensive on-site data acquisition strategy incorporated ground-level and aerial scanning using both photogrammetry and LiDAR technology. Additionally, we gathered ground control points to ensure data precision. The inclusion of LiDAR technology enabled us to capture intricate details and penetrate through vegetation.

‍

LiDAR and Photogrammetry Post-Processing

We refined and cleaned the raw data, eliminating any noise or discrepancies. We generated point clouds, orthomosaics, and 3D models with meticulous attention to detail, ensuring precise representation of the structure as basis for subsequent work. We  integrated ground-level and aerial datasets, aligning the point clouds to measure and model the building.

‍

Building Information Model

We precisely modelled the exterior of the building including walls, doors, and windows, stairs, railings, surrounding topography, and roof-mounted HVAC systems, accurately depicting precise location, orientation, and size.

This comprehensive Scan-to-BIM approach, ensured a high level of detail and provided architects with starting point for their design to improve the facade of St. Elizabeth Retirement Residence.
