Context and Background

• The project was a relatively modest demolition effort at a decommissioned ore processing facility in Svappavaara, Northern Sweden
• The client, Luossavaara-Kiirunavaara Aktiebolag (LKAB), is a state-owned Swedish mining company founded in 1890. The company mines at Kiruna and at Malmberget in northern Sweden supplies about 80% of Europe’s iron ore.
• The consultant, Tikab, is a Stockholm-based consultancy providing services in structural engineering, digital project management and software development.

Client Vision & Goals (LKAB by project manager Stefan Emmoth)

• • Take ownership of project information rather than relying solely on consultants.
  • Full transparency and real-time oversight of progress and communication.
  • Use of StreamBIM to centralize models, point clouds, and communication.
  • Emphasis on visual clarity (3D models vs. old 2D drawings) for understanding and communication.
  • Ensure traceability and structured information flow.
  • Make the system accessible and easy-to-use, especially for local demolition contractors.

Challenges Faced

• Original documentation consisted of paper drawings from 1960s with uncertain accuracy.
• No existing CAD or BIM models.
• Only point clouds from drone scans were available.
• Needed to develop a usable digital model from scratch to support tendering and execution.

Digital Transformation Approach

1. Point Cloud Conversion:
   • Created simple 3D geometries from drone scans.
   • Modeled key structures (steel, concrete), terrain, and traffic flows for safety planning.
2. Model Coding & Structuring:
   • Tagged model elements by plant parts, underground vs. above ground, operational status, and demolition phases.
   • Color-coded stages for visual clarity (e.g., green = stage 1 demo, purple = to be kept).
3. Tender Preparation:
   • Used volume calculations (e.g., cubic meters of concrete) for quantity take-offs.
   • Created model-based views and sections linked with point clouds for clear tender documentation.

On-Site Implementation & Training

• Conducted a workshop in Kiruna to train Polish and Swedish demolition workers in using StreamBIM.
• Workers were guided through using checklists, creating issues/topics, and QA documentation.
• Emphasis on reducing emails and promoting direct platform usage.

Site Operations & Quality Assurance

• Daily site diaries entered directly into StreamBIM using checklists.
• Developed QA templates for contractor documentation needs.
• Enabled real-time tracking and full client visibility.
• All communication, images, and updates were centralized and structured.

Feedback and Evaluation

• A project-wide evaluation checklist was created for ongoing feedback during demolition.
• Goal: Collect structured feedback from all participants.
• Aimed at knowledge transfer back to LKAB and to Rendra (StreamBIM developers).

Conclusion

• The project successfully demonstrated how even an old, undocumented industrial site can be transformed into a modern, digital BIM-driven demolition project.
• The approach empowered the client (LKAB) with control, transparency, and structure.
• The system proved intuitive enough for field crews new to digital tools.
• The experiences made will influence future industrial projects and future StreamBIM development.
