BUSINESS CHALLENGES

Our Client

DIGI-TEXX’s client is a software company in Asia, specializing in Spatial Digital Twin technology. Our client primarily serves the Architecture, Engineering, and Construction industries, as well as Facility Management.

The client focuses on transforming real-world spatial data into accurate digital environments to optimize building design, operation, and maintenance.

Project Challenges

The client needed to improve the accuracy and synchronization between 3D-captured building data and 2D architectural drawings. However, the project posed multiple challenges:

  • Handling high data volume efficiently – thousands of images and videos daily – while meeting strict project deadlines.
  • Complex spatial matching between different data formats (2D drawings vs. 3D visual captures).
  • Maintaining annotation precision and consistency across large datasets.

Project Scope

DIGI-TEXX provided a dedicated annotation team working directly on the client’s proprietary system to:

  • Review captured building images and videos.
  • Identify and annotate matching anchor points between captured visuals and floor plans.
  • Perform 2D and 3D mapping annotation based on project-specific BIM guidelines.
  • Ensure annotation outputs are aligned with spatial modeling standards to reduce errors in digital twin representations.

Our core strength in delivering this project:

  • Our highly specialized resource team, whose members possess technical backgrounds in engineering and architecture. 
  • Our team’s expertise maintains precise, on-point communication allows us to provide the proactive feedback and strategic advice necessary to optimize project outcomes.
  • We ensure the technical integrity of complex spatial data while driving operational efficiency.

DATA ANNOTATION SERVICE FOR BIM SYSTEM

Our project success is anchored in a sophisticated, end-to-end resource management designed for maximum efficiency:

  • Precision Recruitment & Onboarding: We leverage a rigorous talent acquisition process to identify and integrate high-skilled annotators who possess the specific domain knowledge required for your project. This ensures a fast-tracked onboarding phase where the team is immediately aligned with project expectations.
  • Agile Resource Management: By continuously optimizing our internal workflows and resource allocation, we minimize operational overhead and overhead costs. This agile management style guarantees smooth, transparent communication and a scalable workforce that adapts to fluctuating project volumes.
  • Quality-Driven Delivery: Every stage of our management cycle is built to safeguard the technical integrity of your data. The result is a high-quality output that bridges the gap between cost-efficiency and the demanding standards of complex AI and engineering projects.

Our process ensured precision, scalability, and transparency across every project phase. Project Flow:

  1. Onboarding & Training: The team was trained on BIM-specific annotation guidelines and the client’s proprietary tools.
  2. Data Intake: Receive and categorize captured building images and videos from the client.
  3. Annotation Execution: Create matching anchor points between real-world captures and architectural floor plans (2D and 3D mapping).
  4. Alignment & Verification: Gradually align both data types to minimize spatial discrepancies.
  5. Quality Assurance (QA): Apply multi-level review to ensure consistent annotation accuracy.
  6. Reporting & Feedback: Submit annotated outputs, track daily progress, and incorporate client feedback for continuous improvement.
