Boost Construction Efficiency & Traceability: Tianbaonet Digital Solutions in Shenzhen & Shanghai Projects

In today’s era of accelerated digital transformation in the construction industry, efficient project management and precise quality traceability have become key factors for construction companies to enhance their core competitiveness. Many construction firms still rely on traditional “photo + text" record-keeping methods, which are no longer adequate for modern construction management requirements. This approach often results in fragmented information, incomplete site reconstruction, inaccurate measurements, and low traceability efficiency, leading to project delays, hidden quality risks, and unclear responsibility—factors that limit project profitability and business growth.

So how can this challenge be overcome? Tianbaonet offers a practical solution: leveraging LCC-3DGS technology (real-time 3D reconstruction and rendering based on Gaussian splatting) in combination with the L2pro handheld scanner and P1 spatial camera, construction progress is digitized in 3D and integrated into daily workflows. This enables fully digital, visual, and traceable construction processes, effectively addressing the core shortcomings of traditional record-keeping. This solution has been successfully implemented in key projects in Shenzhen and Shanghai, setting a replicable benchmark for digital transformation in construction.

The Nanshan office building project in Shenzhen faced complex, multi-floor construction. The client required high-precision documentation of the entire construction process on floors 12, 13, and 15, ensuring data accuracy while minimizing interference with normal construction schedules.

Traditional methods involved assigning personnel to photograph each floor and manually record points, which was time-consuming, prone to omissions or errors, and cumbersome for later verification or traceability. To address this, the Tianbaonet technical team deployed a digital solution using the L2pro handheld scanner and LCC-3DGS technology, offering simple, efficient, and fully operational on-site implementation.

During site data acquisition, the advantages of the L2pro handheld scanner were fully realized: portable, one-button operation, requiring no complex setup, enabling a single technician to complete scanning. Three floors of comprehensive data were captured in just 20 minutes, dramatically reducing labor and time costs. With the LixelGo mobile app, technicians could monitor point clouds, scan trajectories, and battery levels in real-time. Any missed areas could be immediately rescanned on-site, avoiding rework and ensuring data completeness.

Once collected, the raw data was imported into LCC Studio software, where LCC-3DGS technology automatically generated a high-fidelity 3D model, accurately replicating every construction detail, including wall structures, piping, and construction nodes. Project managers can use this 3D model to:

• Freely navigate and immerse themselves in the construction site, understanding progress without being physically present.
• Measure dimensions and areas precisely, add annotations, and provide accurate data for progress control and quality inspections, solving the “unmeasurable" limitations of traditional records.
• Export high-quality point cloud data for as-built modeling and property survey verification, achieving “one-time capture, multiple-use", greatly enhancing project acceptance efficiency.

The project manager noted:
"Previously, verifying construction records took over two hours daily, with constant concern over omissions. With the L2pro scanner and LCC-3DGS, we can record three floors in 20 minutes. The 3D model is intuitive, and progress tracking and quality checks improved by over 60%, while human error is virtually eliminated."

Clearly, the L2pro + LCC-3DGS solution from Tianbaonet overcomes the fragmented data bottleneck of traditional record-keeping, enabling high-efficiency management of complex multi-floor construction projects, ensuring accurate data while reducing management costs—making it the preferred digital solution for office buildings, residential buildings, and factories.

The Jiading R&D base project in Shanghai focused on detailed documentation of specialized areas and full-process traceability, requiring clear records of material storage, equipment placement, and workflow execution. Traditional photos only provide partial perspectives, failing to fully reconstruct the site. When quality issues arise, tracing the responsible process and personnel becomes difficult, causing project management challenges.

To meet these requirements, the Tianbaonet team implemented a P1 spatial camera + LCC-3DGS technology solution, leveraging the P1’s high-precision detail capture to build a comprehensive digital archive of the construction process.

Equipped with two fisheye and two front-facing cameras and offering 4000*3000 resolution, the P1 spatial camera enables rapid, high-accuracy capture by a single technician, without affecting ongoing construction. Once imported into LCC Studio, the LCC-3DGS algorithm automatically generates 1:1 3D models, with superior clarity and color fidelity compared to traditional records, accurately reproducing material placement, equipment layout, and workflow execution—achieving complete, zero-omission site documentation.

The solution provided three major benefits:

• Overcoming the limitations of traditional “partial view" photos, creating continuous, complete, and visual digital archives where every construction step is traceable.
• High-definition detail capture, clearly identifying material specifications and construction processes, supporting quality inspection and avoiding hidden defects.
• Full-process record retention, covering progress milestones, material usage, and workflows, allowing rapid traceability to specific steps and personnel, minimizing disputes, and providing data for post-project review and process optimization.

The technical lead noted:
"During construction, the 3D model helped identify improperly stored materials in time, avoiding conflicts in subsequent workflows. Rework costs were saved, and construction progress was maintained. Previously, tracing quality issues required hundreds of photos and dozens of pages of notes. Now, we can quickly locate root causes in the 3D model, improving traceability efficiency by 80%."

The successful implementation of Shenzhen and Shanghai projects demonstrates the practicality and reliability of Tianbaonet’s construction digital solutions. Many firms may ask: when to choose L2pro vs. P1? They are not substitutes but complementary. Both leverage LCC-3DGS for automated, unattended modeling, balancing efficiency and precision to fit diverse construction scenarios.

• For multi-floor, complex structures requiring precise measurements and as-built verification, the L2pro handheld scanner is ideal.
• For specialized areas focusing on detailed retention and full-process traceability, the P1 spatial camera is preferred.
• Used together, they provide all-scenario, full-process digital construction management, maximizing the value of digital technology.

From the Shenzhen office building to the Shanghai R&D base, Tianbaonet’s LCC-3DGS-based solution with L2pro and P1 creates a permanent 3D digital archive, fully addressing traditional construction record challenges and delivering three key benefits:

1. More Efficient Control: Accelerated progress tracking and quality inspection, reduced manual recording workload and human error, freeing managers to focus on construction oversight and problem-solving, preventing delays.
2. More Reliable Archives: Overcoming fragmented, hard-to-access, high-maintenance traditional records. 3D models are permanently stored and easily retrievable, reducing management costs.
3. Clearer Traceability: Complete construction lifecycle data retention, enabling precise tracking of every step and detail, rapid root-cause identification, and clear responsibility assignment, minimizing disputes and supporting process optimization for future projects.

Digital transformation in construction is no longer optional—high-efficiency, accurate, and traceable digital management is critical for overcoming industry bottlenecks. Tianbaonet’s twin Shenzhen-Shanghai projects provide a replicable and scalable model for digital construction management, suitable for office buildings, factories, R&D centers, and municipal projects.

Looking ahead, Tianbaonet will continue to deepen expertise in construction digitization, optimize L2pro and P1 performance, and deliver solutions that meet on-site needs, helping more construction companies achieve digital upgrades, reduce costs, enhance quality traceability, and drive high-quality industry development.
