2023 Microtunneling Short Course Session

Microtunneling Short Course Celebrates 30th Anniversary

The 2023 Microtunneling Short Course – the 30th anniversary of the course – was held April 12-14 in Scottsdale, Arizona, with 166 people in attendance.

The venue was Scottsdale Stadium, the spring training home of the San Francisco Giants. It was the second year in a row that the course was held at this venue, with the previous courses being held in Colorado.

The course was founded in 1993 by Tim Coss (Microtunneling Inc.), Levent Ozdemir (Ozdemir Associates) and Bernie Krzys (Benjamin Media/Trenchless Technology magazine) as the only event focused on the then-emerging installation technology. It continues to be the largest gathering of professionals dedicated to microtunneling technology, attracting attendees and presenters from across North America and Europe. This year’s course boasted 166 attendees from five countries.

The course itself covers all aspects of tunneling from leading experts in the field, covering design, construction, equipment, case histories and more. This year’s course opened with a presentation from Paul Nicholas of AECOM, reflecting on the history of microtunneling. Nicholas and Glenn Boyce of Delve Underground, who gave a case history presentation, were also presenters at the inaugural course held in 1993.

One of the highlights of the agenda was a contractor’s panel discussion, organized by the North American Microtunneling Association (NAMA), an organization of contractors heavily involved in microtunneling that formed in 2012. Brenden Tippets (Nada Pacific), was the moderator, with Pete Schraufnagel (Super Excavators), Dave Ellett (BRH Garver), Ray Post (Huxted), and Adam Stremcha (Michels) as panelists.

Other highlights of the course included many networking events, including a 30th anniversary rooftop reception at the Canopy by Hilton on April 10, a welcome reception at the stadium on April 11, the annual banquet dinner at the Museum of the West on April 12, and a special networking reception at the Brat Haus sponsored by Tunnel Services Group on April 13.
