Developing a BIM and Simulation-Based Hazard Assessment and Visualization Framework for CLT Construction Design

Abstract

One emerging trend in sustainable medium-density construction is the use of mass timber products such as cross laminated timber (CLT), which is a novel approach that involves numerous connectors. Researchers have not previously investigated the potential health impacts of different connectors. This paper proposes a framework to correlate the specification of CLT connectors to the potential risk of exposure to hand arm vibration syndrome (HAVS). We also propose an innovative adaptation of the Location-Based Management System flow line by adding a health risk dimension. The usefulness of the proposed framework is tested using a cutting-edge case study building, the tallest timber building in Scotland. The contribution of this research is a novel appreciation of the impact on installers’ Health & Safety based on the specified type of CLT connectors. With the methodology outlined in this paper, a HAVS variable can be added to design analysis to increase social sustainability in the built environment alongside other sustainability pillars. The findings are relevant to structural engineers, architects, key industry stakeholders, and researchers in the built environment.
