L2pro + P1 with LCC-3DGS: Achieving Measurable, Navigable, and Traceable 3D Construction Archiving
2026-04-10
How to Effectively Manage the Construction Process?
How to Precisely Trace Quality Issues?
If your answer still relies on "photos + written records,"
Then it’s already outdated!
The L2pro handheld scanner and P1 spatial camera,
Combined with LCC-3DGS technology,
Turn 3D digital archiving of construction progress into a daily practice.
In the wave of digital upgrades in the construction industry, quality traceability and refined process management have become core topics. Traditional methods, such as photos, written notes, and video recordings, result in fragmented information, incomplete scene restoration, non-measurable data, and inefficient traceability—falling short of modern construction management demands. LCC-3DGS technology (based on real-time reconstruction and rendering with 3D Gaussian splashing) automatically converts on-site scan data into high-fidelity, measurable, and immersive 3D models, fundamentally solving the “easy to record, difficult to restore” issue.
Tianbaonet, in combination with the L2pro handheld scanner, P1 spatial camera, and LCC-3DGS technology, offers a comprehensive construction digitalization solution. By applying this technology in construction projects in cities like Shenzhen and Shanghai, it has significantly improved construction management efficiency and enabled upgrades in digitalization, visualization, and traceability of construction sites.
Case 1: A High-End Office Building in Nanshan, Shenzhen—20 Minutes, Three Floors, One-Click Modeling
In a high-end office building construction project in Nanshan District, Shenzhen, Tianbaonet technicians used the L2pro handheld scanner and LCC-3DGS technology to perform digital archiving of the construction site. The L2pro scanner, with its lightweight, simple operation, and one-click startup features, quickly became the primary tool for data collection on the project.
- Project Background
The construction project in Nanshan required high-precision recording and archiving of the construction process on the 12th, 13th, and 15th floors. - Equipment Used
L2pro Handheld Scanner - Field Data Collection
✅ Lightweight and easy to operate, one-click start, supports high-speed scanning
✅ Only 20 minutes were required to complete the full data collection for three floors
✅ With LixelGo mobile app, real-time viewing of point clouds, tracks, and battery status enabled on-site detection and immediate scanning corrections
- Highlights of Results
After data collection, raw data was imported into LCC Studio software, and the LCC-3DGS technology automatically generated a 3D digital model, accurately replicating the actual construction site. With the generated 3D model, project personnel could:
✅ Roam freely in the immersive view of the actual construction site
✅ Accurately measure dimensions and areas, and add annotations
✅ Output high-quality point cloud data for final model and property survey acceptance

- Advantages of the Solution
The L2pro handheld scanner and LCC-3DGS technology break the fragmentation bottleneck of traditional construction records, enabling comprehensive tracking of construction progress, details, and site conditions. With 3D digital models, managers can clearly track each stage of the construction progress, improving project management transparency, reducing manual verification workload, and minimizing human error risks.

Case 2: A Research and Development Base in Jiading, Shanghai—High-Definition Detail Replication, Complete Construction Scene Preservation
At a research and development base construction project in Jiading District, Shanghai, Tianbaonet technicians used the P1 spatial camera and LCC-3DGS technology to digitally archive the construction site. Unlike the L2pro handheld scanner, the P1 spatial camera uses a multi-camera array to offer higher capture precision and better detail restoration.
- Project Background
The R&D base project in Jiading needed to document and trace specific areas during the construction process. - Equipment Used
P1 Spatial Camera - Highlights of Results
The data collected by the P1 spatial camera was also imported into LCC Studio software, and using the LCC-3DGS technology, the 1:1 replica of the construction site 3D model was automatically generated. The results were:
✅ Models with clearer details and more realistic colors, offering highly accurate restoration, clearly showing material piles, equipment placements, and construction process details
✅ Complete recording of the entire construction process, including progress, material usage, and operational steps, with no omissions or blind spots
✅ Breaking the limitations of traditional photos' “partial view,” achieving continuous, complete, and visualized archiving

- Advantages of the Solution
The P1 spatial camera, equipped with two fisheye cameras and two front-facing cameras, with a 4000×3000 high-definition resolution, generates 3D models with better detail restoration, providing robust data support for progress optimization and quality control during subsequent construction phases. This digital solution helps project managers better understand the actual situation on-site, greatly enhancing the fine management level of the construction process and enabling real-time monitoring of progress and quality control.
Collaborative Technical Force: Building a Full-Chain Construction Digitalization Solution
The successful practices of the Shenzhen and Shanghai projects fully validate that the L2pro handheld scanner and P1 spatial camera are not substitutes but rather complementary tools with clearly defined roles, working together in a flexible, golden combination. Powered by LCC-3DGS technology, both devices enable fully automated, intervention-free modeling, with the entire process managed by intelligent software, balancing efficiency and precision and adapting to different construction site requirements.
- L2pro is ideal for large areas, high precision, and measurable data collection, making it suitable for multi-floor and complex structures.
- P1 excels at lightweight, fast data collection with high detail restoration, ideal for specific areas and scenes requiring detailed preservation.
