Smart and Sustainable Construction (SSC) Research Group directed by Dr. Changbum R. Ahn focuses on data-driven techniques and smart-sensing technologies for transforming traditional project delivery processes into integrated sustainable practices, including construction workers’ unsafe behavior monitoring using wearable sensing, occupancy sensing and eco-feedback based existing wireless network infrastructure, automated construction resource tracking, and life-cycle assessment of civil infrastructure systems.
