Mapping of existing structures, also known as as-built surveys, provides an accurate record of the current state of buildings, infrastructure, and facilities. At Fourtsadakis, we offer precise as-built mapping services using advanced 3D laser scanning, photogrammetry, and GIS integration, ensuring reliable data for renovation, maintenance, or technical studies.
What Is As-Built Mapping?
As-built mapping involves capturing the real-world conditions of a structure after construction or during operation. This includes geometry, dimensions, and spatial relationships, creating a detailed digital representation that reflects the actual built environment rather than just the original design.
These surveys are critical for:
- Renovation and retrofitting projects
- Maintenance and facility management
- Legal and cadastral documentation
- Engineering and architectural studies
- Integration with BIM and CAD workflows
Key Benefits
- Accuracy: Provides precise measurements of existing structures
- Time savings: Faster and safer than manual measurement methods
- Reduced errors: Minimizes discrepancies between design and reality
- Improved planning: Supports technical studies and construction modifications
- Integration: Compatible with BIM, CAD, and GIS systems
Applications
- Residential, commercial, and industrial buildings
- Infrastructure and bridges
- Historical buildings and heritage sites
- Renovation and retrofit planning
- Facility management and documentation
