When it comes to capturing existing conditions efficiently and accurately, a well-executed as-built survey is essential. Recently, our team completed a comprehensive as-built survey for a 40,000-square-foot commercial building in North Augusta, South Carolina. The project required detailed documentation of the structure’s existing conditions, including floor plans, roof plans, ceiling plans, exterior elevations, and a site plan.
Scope of Work
The goal of this as-built survey was to provide the client with highly accurate and detailed digital documentation, including:
- Floor Plan: Capturing interior layout, walls, doors, and major structural elements.
- Roof Plan: Documenting slopes, mechanical units, and drainage systems.
- Ceiling Plan: Recording ceiling heights, materials, lighting, and mechanical components.
- Exterior Elevations: Detailing facade features, fenestration, and architectural elements.
- Site Plan: Mapping the building footprint, adjacent structures, and key site features.
Technology & Process
To ensure precision and efficiency, our team utilized advanced 3D laser scanning technology. This included the use of high-resolution scanners capable of capturing millions of data points per second. The resulting point cloud provided a highly accurate representation of the building’s geometry, reducing the likelihood of errors and omissions in the final deliverables.
On-Site Data Collection
- Our surveyor was on-site for one day, leveraging a Faro scanning system to capture comprehensive 3D data.
- Multiple scan positions were used to ensure complete coverage of both interior and exterior spaces.
- The collected point cloud data was then registered and processed to create a unified digital model of the building.
Deliverables & Timeline
The client received their deliverables seven days after the site visit, ensuring a fast turnaround without sacrificing quality. The final package included:
- Revit Model: A highly detailed and structured BIM model suitable for design and planning purposes.
- E57 File: A universal point cloud format for further analysis and integration.
- AutoCAD Drawings: 2D documentation for quick reference and traditional drafting needs.
Why Use 3D Laser Scanning for As-Built Surveys?
- Accuracy: Laser scanning eliminates human error and ensures precise measurements.
- Efficiency: Capturing a building of this size in a single day minimizes disruption to operations.
- Comprehensive Documentation: The point cloud serves as a permanent digital record of existing conditions.
- Seamless Integration: Deliverables in multiple formats allow architects, engineers, and contractors to work seamlessly across platforms.
Conclusion
This project highlights the value of 3D laser scanning in as-built surveys. By utilizing cutting-edge technology, we delivered high-quality documentation efficiently, ensuring our client had the accurate data they needed for their project. Whether it’s a commercial, industrial, or residential building, our team is ready to provide precise and reliable existing conditions documentation.
