The Boring Company’s tunnel boring machine is nearly complete with the first half of the dual tunnel people mover system servicing the Las Vegas Convention Center. The secretive tunnel project is reported to cost $52.5M and feature self-driving vehicles utilizing the Tesla chassis. The largest vehicle will fit 16 people and multiple vehicles can be platooned to load and travel together much like a conventional light rail or subway system but without the connections. Once the TBM finished the first bore, it will be disassembled and brought back to the starting point to excavate the second tunnel. The entire project is supposed to be online for the 2021 Consumer Electronics Show (CES).

Those with interest in rock mechanics and tunneling might be interested in this project. The Ontario Power Generation (OPG) company is the owner of a $600M (Canadian) construction project to create a third hydro power tunnel under Niagara Falls. Apparently the project is having all kinds of problems with overbreak in some very difficult tunneling conditions which means very slow progress and big $$ overruns. (Photo from niagarafrontier.com)
I’ve been meaning to post something on this project for some time. I admit that my perspective is biased by the viewpoint you can find on the Ontario-geofish blog. I’ve mentioned Harold Asmis before, he’s the owner of the OG blog, and a former OPG employee if I understand correctly. He left OPG for a career doing geophysics and earthquake engineering for the Nuclear Power industry in Canada. I highly recommend his blog, he has great insight into tunneling, earthquakes, siting of nuclear power plants not to mention opinions on all kinds of other things. His writing style is very colorful and entertaining as well.
So, Harold has written a whole series of blog posts on the Niagra Tunnel project, including a 5-part series entitled "The Disaster of the Niagara Tunnel" and a 4-part series called "Niagara Tunnel: doing it Right". He is not directly involved with the project, but his long career with OPG and related disciplines gives him some great insights. I’ve collected a list of some of his blog posts on the Niagara Tunnel project as well as a few other links about the project. Click through for the good stuff.
