The October–November 2025 issue of the North American Tunneling Journal features insights from ASI Group’s Scott Black, Sr. Vice President Operations and Hyperbaric Safety Director, in the article “Extreme Tunneling.”
The piece explores how the tunneling industry is adapting to increasingly complex and unpredictable ground conditions—and how collaboration, early engagement, and safety-focused planning are key to success.
Speaking from ASI’s leadership in hyperbaric tunneling support, Scott emphasizes the growing importance of pre-project planning, regulatory compliance, and industry education:
