If Irish Engineers saying it, Elon Musk had better to listen to it

`Before Elon Musk builds a tunnel under Chicago, he should remember the Chicago Flood`

n 1992, a leak in a system of long-forgotten freight tunnels underneath the city flooded Chicago's downtown, and caused $3.2 billion in damage

When the first Severomuysky Tunnel in Siberia was bored, the name of the country was Soviet Union.
4 Decades later the second Severomuysky Tunnel is bored. The name of the country changed to Russia.
One thing did not change. The tunnel boring machine brand used. It's a Robbins

It's a Robbins.
City of Dallas unveils the largest hard rock TBM ever to bore in the United States.

The 11.6 m (38.1 ft) diameter #Robbins Main Beam TBM will excavate the 8 km (5 mile) Mill Creek Drainage Relief tunnel, and its size is not its only distinction. The adaptable machine will change size partway through the bore, to a more compact 9.9 m (32.5 ft).

Alice, the Réseau express métropolitain‘s #TheRobbinsCompany-supplied giant tunnel boring machine (TBM) is ready to bore a 3.5-kilometre underground passage from the Technoparc to the REM station beneath Montreal-Trudeau International Airport.

The REM named the machine after Alice Evelyn Wilson (1881-1964), a scientist and the first female geologist with Geological Survey of Canada.

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. Submit your questions in advance to webinars@robbinstbm.com to get a thoughtful, well-researched answer during the Q&A session.
