3D Laser Scanning and Archicad Modeling of a 7,000 sq ft Mansion in Chicago, Illinois
Project Overview
We performed comprehensive 3D laser scanning of the interior and exterior of a 7,000 sq ft residential mansion in Chicago, Illinois. The on-site data capture was completed in a single business day, and all project deliverables were provided within two weeks.
The survey included detailed measurements of the existing conditions, accurately capturing all visible geometry, dimensions, MEP elements, built-in millwork, site features, and elevation details. The collected data was used to create a highly accurate 3D Archicad model at LOD 400, including all visible MEP components, railings, built-in millwork, and exterior elements.
The client required a precise digital representation of the existing property. By utilizing high-precision 3D laser scanning technology, we significantly reduced the time required for traditional field measurements while minimizing on-site surveying costs. The complete Archicad model and documentation package were delivered within just two weeks, providing the architect with reliable existing-condition information for design and renovation planning.

Methodology and Project Timeline
Day 1 – On-Site Laser Scanning
Efficient fieldwork was carried out to capture all interior and exterior areas of the mansion.
Days 2–3 – Point Cloud Processing
Scan registration, alignment, and cleaning were completed to prepare the point cloud for BIM modeling.
Days 4–10 – 3D Archicad Modeling
A detailed Archicad model was developed, including the building structure, surrounding site, visible MEP components, railings, built-in millwork, and exterior elevations.
Days 11–14 – Quality Assurance and Delivery
The final model and documentation package underwent comprehensive quality control before being delivered to the client.
Deliverables
- Registered point cloud data in E57 and RCP formats
- Detailed LOD 400 Archicad model (.PLN and .PLA)
- Modeling of visible MEP elements and built-in millwork
- Photographic documentation
- Accurate existing-condition documentation for architectural design and renovation
Project Benefits
By utilizing high-precision 3D laser scanning technology, the client received reliable and accurate existing-condition documentation without the need for repeated site visits. The delivered point cloud and Archicad model provide a solid foundation for architectural design, while significantly reducing survey time, minimizing fieldwork, and lowering overall project costs.
