As-Built Plans
Project Overview
DCMS conducted a comprehensive as-built exterior elevation survey for Douglas Hospital, a key healthcare institution in Quebec. This heritage restoration project, commissioned by the Government of Quebec and GR7 Architecture, required high-accuracy documentation of over 85 building elevations to guide the restoration process while preserving the architectural integrity of the hospital’s historic facades.
Deliverables
85+ Detailed Exterior Elevations – Ensuring accurate documentation of the hospital’s facade and structural details.
High-Density LiDAR Point Cloud Data – Providing an exact digital replica of the building’s exteriors.
Georeferenced Orthophotos & Drone Roof Plans – Supporting compliance and facade material selection.
Thermographic Analysis of Facades & Roofs – Assisting in energy efficiency planning and preservation efforts.



Our Role & Technology
We used terrestrial 3D laser scanning and drone photogrammetry to map the entire hospital’s exterior with millimeter precision. Our team delivered a full set of elevation drawings, orthophotos, and thermal reports to support design and conservation decisions. Tools used:
Leica RTC360 for terrestrial LiDAR.
DJI Phantom 4 RTK for aerial mapping,
Autodesk Revit, and AutoCAD for detailed documentation and analysis.
Key Challenges & Solutions
Multiple historic elevations: We delivered over 85 high-accuracy elevation drawings using LiDAR and drone data.
Material condition analysis: Thermographic imaging identified weak points for targeted restoration.
Preservation standards: All outputs complied with provincial heritage documentation guidelines.
