Historic Building Scan to BIM Case Study
Acurabim converted point cloud scans of a historic East Grace Street residence into an accurate BIM model for preservation-grade renovation.
Project Overview
400 East Grace Street – Scan to BIM for Historic Residential Building
400 East Grace Street is a historic residential building located in downtown Richmond, Virginia. The project required the conversion of laser-scanned reality capture data into an accurate BIM model to support renovation planning, asset management, and future facility operations.
The primary objective was to create a reliable digital representation of the existing structure while preserving the architectural character of the historic property.
The Challenge
Historic Building Complexity
- Original construction dating back to 1922
- Variations in floor layouts and wall alignments
- Aging architectural elements requiring accurate capture
Existing Conditions Documentation
- Limited availability of updated as-built drawings
- Requirement for highly accurate existing-condition verification
Point Cloud Processing
- Managing large laser scan datasets
- Translating complex scan data into an intelligent BIM environment
