The Challenge
AsBuilt was contracted to provide 3D laser scanning, modeling, and engineering support for an all-purpose sports and event arena. The project required accurate existing-condition documentation to support the installation of a new interior LED sign system.
The installation location involved overhead structural framing, architectural elements, utilities, and existing equipment within an active venue environment. The engineering team required precise dimensional data to:
- Confirm structural attachment points
- Verify load-bearing members
- Identify potential clashes with utilities
- Validate elevations and clearances
- Minimize installation risk in a high-visibility public facility
Without accurate as-built documentation, there was increased risk of misalignment, rework, and schedule delays.
The Solution
High-Resolution Interior Laser Scanning
AsBuilt conducted a detailed terrestrial laser scan (LiDAR) of the designated arena interior area. The scan captured:
- Structural steel framing and supports
- Overhead utilities and electrical systems
- Architectural features
- Access points and rigging constraints
The data was registered and processed into a high-accuracy point cloud, representing exact field conditions.
3D As-Built Modeling
Using the verified point cloud, AsBuilt developed a precise 3D as-built model (DWG format) of the installation area. The model provided:
- Accurate geometry of structural members
- Verified mounting elevations
- Clearance analysis for LED sign placement
- Engineering-ready backgrounds for design coordination
The digital model enabled the client to confidently plan and position the LED sign prior to fabrication and installation.
Deliverables
- Post-processed, registered point cloud
- Photorealistic 3D visualization
- 3D as-built model (DWG)
Results & Impact
The project delivered reliable, engineering-grade documentation of the arena’s interior structure to support LED sign installation. By leveraging 3D laser scanning and modeling, AsBuilt reduced uncertainty, improved coordination, and ensured accurate structural integration within an active event venue.
