Nepal’s first TBM-driven tunnel was a success by any standard: The Robbins Double Shield machine bored up to 1,200 meters a month and finished the Bheri Babai Diversion Multipurpose Project nearly a year early. But how were crews able to bore so quickly? And what made the contractor and owner ultimately decide to use a TBM for the first time?
Join our complimentary 30-minute webinar with Brad Grothen P.E., Robbins Technical Director, and Missy Isaman P.E., Robbins Project Engineer, as we discuss the challenges, lessons learned, and recommendations for future tunnels in mountainous geology.

Modern TBMs are data-driven systems, from ground investigation tools ahead of the machine to touch-screen technology in operator’s cabins, to integration with programs on the surface. Today’s TBMs, paired with cutting-edge data collection and monitoring, can efficiently bore in even the most demanding circumstances.
In this complimentary 40-minute webinar, Robbins VP of Operations Steve Chorley and Aaron McClellan, Tunnel Superintendent III for Kiewit Underground, will explore the latest and greatest innovations in technology for TBMs. Nearly all the parameters of a TBM can be monitored today, and this data can be transmitted via radiating coaxial cables to offices on the surface or even mobile phones. Simple observations, such as cutterhead RPM and penetration rate in a given geology, can result in altered operational parameters and reduced thrust that can speed up advance and increase cutter life. All that is required is proactive analysis by management and engineers, and good communication with the TBM operator.

TBM maintenance: it’s one of the most important factors predicting project success, but it is often treated with less importance than it deserves. Experience shows, however, that maintenance plays just as much a part in the excavation rates as the proper TBM design. Regular maintenance can keep future rebuild costs low and keep equipment efficiency high while maximizing advance rates. Conversely, a lack of maintenance, improper operation, and/or severe ground conditions can result in undue wear and slow advance rates. In a worst-case scenario, it can even require rescuing and refurbishing of a TBM.
In this 40-minute complimentary webinar, Robbins Sales Manager Europe Detlef Jordan and iPS Tunnel Manager Barrie Willis will discuss case studies of both optimal and suboptimal maintenance and operation of TBMs. Suboptimal examples will be discussed where TBM maintenance was insufficient and required rescuing of the machine once it became stuck or immobile. Optimal case studies will form a guideline for recommended machine maintenance to prevent the substantial damage that can occur. Rebuild strategies for recovered TBMs in various adverse conditions will also be discussed.
