Planning a Large Facility Scanning Project

Planning Large Facility Scanning Projects

# Phase 1: Scoping

Define Objectives
- What deliverables are needed?
- Who will use the data?
- What accuracy is required?
- What timeline is realistic?

Gather Existing Documentation
- Floor plans (even outdated)
- Site plans
- Previous surveys
- Building systems info

Site Assessment
- Total square footage
- Number of floors/buildings
- Access restrictions
- Operating hours

# Phase 2: Method Selection

Method Evaluation Matrix

| Factor | Tripod | Mobile | Matterport |
|--------|--------|--------|------------|
| Accuracy | ★★★★★ | ★★★★ | ★★★ |
| Speed | ★★ | ★★★★★ | ★★★★ |
| Cost | ★★★ | ★★★★ | ★★★★★ |
| BIM ready | ★★★★★ | ★★★★ | ★★ |

Typical Large Facility Approach
- NavVis VLX3 for general coverage
- Trimble X12 for MEP rooms
- Drone for rooftops
- Combine methods strategically

# Phase 3: Logistics

Access Planning
- Rolling access schedule
- After-hours requirements
- Security/escort needs
- Equipment staging

Control Network
- Establish building control
- Connect to site/survey control
- Document coordinate system

Team Coordination
- Site contacts
- Safety requirements
- Communication plan
- Daily check-ins

# Phase 4: Execution

Quality Control
- Daily coverage verification
- Real-time registration check
- Photo documentation
- Issue tracking

Documentation
- Scanner settings log
- Coverage maps
- Control point records
- Deviation notes
