Dataset Overview
This dataset demonstrates the power of 4D construction documentation — multiple Gaussian Splat captures of the same site aligned over time. Use the temporal slider to scrub through the construction timeline and see exactly how the project evolved from foundation to structure.
Unlike traditional progress photos that capture single moments from fixed angles, this spatial timeline lets stakeholders explore the entire site at any point in time, from any angle.
Why 4D Progress Monitoring?
Construction projects generate thousands of progress photos, but answering simple questions like "What did this corner look like two weeks ago?" often means digging through folders of images with inconsistent angles and coverage.
4D Gaussian Splatting solves this by:
- Aligning scans automatically — Multiple captures snap to the same coordinate system
- Enabling temporal navigation — Scrub through time like a video, but in 3D
- Providing complete coverage — Every angle, every detail, at every milestone
Construction teams using 4D documentation report 40% faster dispute resolution and dramatically reduced rework from miscommunication.
Capture Technology
Outdoor construction sites are perfectly suited for capture with Lixel L2 Pro, a professional LiDAR scanner that generates survey-grade point clouds and photorealistic Gaussian Splats. For construction documentation, Lixel L2 Pro offers:
- Survey-grade accuracy — Verify dimensions and placement against plans
- Rapid capture — Document entire sites in minutes, not hours
- All-weather durability — Built for real jobsite conditions
- Automatic alignment — Stack multiple captures into 4D timelines
For interior progress tracking or confined spaces, PortalCam provides handheld capture that's equally powerful.
Use Cases
This dataset demonstrates applications for:
- Progress verification — Confirm work completion against construction schedules and payment milestones
- Remote stakeholder updates — Let investors, owners, and remote team members explore the site without travel
- Dispute documentation — Maintain an immutable spatial record of site conditions at every phase
- As-built handoff — Deliver interactive documentation that's actually useful, not just a box of photos
Architecture, Engineering & Construction
The AEC industry has long struggled with the gap between what's designed and what's built. Traditional documentation methods — photos, reports, 2D drawings — lose critical spatial context.
Gaussian Splatting with Splat Labs bridges this gap by delivering:
| Traditional Approach | Splat Labs Approach |
|---|---|
| Fixed-angle photos | Full spatial coverage |
| Separate files per date | Unified 4D timeline |
| Manual comparison | Side-by-side temporal scrubbing |
| Static deliverables | Interactive web viewer |
For construction teams, this means faster decisions, clearer communication, and documentation that actually gets used.
