Investigating the Impact of Augmented Reality and BIM on Retrofitting Training for Non-Experts

Area of Science:

• Construction Management
• Human-Computer Interaction
• Digital Fabrication

Background:

• Augmented Reality (AR) and Building Information Modeling (BIM) integration offers on-site visualization for construction.
• Retrofitting existing buildings presents unique challenges for integrating AR and BIM technologies effectively.

Purpose of the Study:

• To investigate the impact of AR+BIM technology on the training process for building retrofitting.
• To assess the potential for AR+BIM systems in future on-site retrofitting applications.

Main Methods:

• A study involving 64 non-expert participants was conducted.
• Participants performed an electrical outlet installation task using either an AR+BIM system or traditional blueprints.
• Performance metrics included task time, accuracy, and perceived physical/cognitive demands.

Main Results:

• AR+BIM significantly reduced task completion time compared to blueprints.
• Performance consistency improved across participants using the AR+BIM system.
• The AR+BIM system decreased the physical and cognitive demands associated with the retrofitting training.

Conclusions:

• AR+BIM technology enhances the efficiency and effectiveness of retrofitting training.
• This technology has strong potential for improving on-site retrofitting procedures in existing buildings.
• Further research can extend AR+BIM applications for more efficient building retrofitting.
