While Metrolinx continues work in Ontario to prepare the launch shaft for the Scarborough Subway Extension’s tunnel boring machine single tunnel calls for a big tunnel boring machine – one that can build a tunnel with a 10.7-meter (35-foot) diameter soon to be the biggest subway tunnel in Toronto The 7.8-kilometer (4.8-mile) Scarborough Subway Extension will be the first subway project in Toronto to operate in both directions within a single tunnel requiring only a single boring machine to create all the necessary space The TBM for the Scarborough Subway Extension is being manufactured by Herrenknecht which has supplied tunnelling technology for underground infrastructure around the world including major subway projects in the UK and around Europe teams at Herrenknecht’s manufacturing facility in Schwanau have been busy preparing a custom-built TBM for the Scarborough Subway Extension After teams complete quality control and testing at the Herrenknecht facility the machine will travel in multiple shipments The TBM shipments are set to arrive on Canadian shores in early 2022 and will then travel by truck to the launch shaft site at McCowan Road and Sheppard Avenue they will lower the assembled machine into the ground so it can begin tunnelling its way south under McCowan Road digging about 10 meters (32.8 feet) of tunnel daily workers will remove the machine from the ground at an extraction shaft that will be built at Midland and Eglinton Metrolinx will also be launching a TBM naming contest later this fall to crowdsource names for Scarborough’s new tunnel boring machine – much the same way the tunnel boring machines used on the Crosstown route were named by the public Connecting decision makers to a dynamic network of information Bloomberg quickly and accurately delivers business and financial information Herrenknecht AG’s headquarters in Schwanau Mid-sized companies are reducing their dependence on China dominating their industries and creating a roadmap to succeed in a new world economy And the cherry on the Black Forest cake: The United States picked up the bill for defense while the Germans devoted all their energies to making money Germany’s two previous irruptions onto the world stage — in 1914 and 1939 — had occurred in the name of nationalism and militarism The new age of globalization allowed Germany to showcase its ability to work across borders in the name of universal prosperity AUCKLAND, NEW ZEALAND & SCHWANAU, GERMANY, SEPT 10, 2018 -- For the modernization of a wastewater treatment plant near Auckland innovative Direct Pipe® technology is in use to install a sea outfall pipeline the machine is tunnelling its way through the New Zealand subsoil into the sea The new sea outfall not only increases the plant's capacity but also sets a new distance world record with Direct Pipe® technology the site crew in New Zealand's Whangaparaoa can report the successful breakthrough of the microtunneling machine "Blanche" contractor McConnell Dowell's project team sets a new distance world record with the Direct Pipe® method Watercare's Army Bay Wastewater Treatment Plant project will create an additional 2.9 kilometer long sea outfall The pipeline connects the pump station with the discharge point This will significantly increase the capacity of the wastewater treatment plant Special attention is being paid to environmental protection so as not to impact the surrounding recreational and fishing area Under no circumstances must the local flora and fauna be affected The Direct Pipe® method is ideal for such sensitive installations Herrenknecht's patented pipeline installation method uses an AVN machine The pipe string is attached to it and simultaneously inserted during the tunneling process This is done with the help of the "Pipe Thruster" Pipeline installation takes place in one step the environmental impact is kept low and the landscape remains intact The highlight of the project is the distance world record cracked at 1,496.48 meters -- the longest pipe string ever laid with Direct Pipe® so far "The world-record breaking Direct Pipe drive at Watecare’s Army Bay project would not have been possible without the expert assistance and timely backup that Herrenknecht provided contractor McConnell Dowell right from tender preparation through establishment of the plant to successful breakthrough,“ says McConnell Dowell Project Manager Brent Whiting The AVN machine was lifted out of the sea at the outfall and towed ashore The new discharge at Watercare’s Army Bay Wastewater Treatment Plant is scheduled to go into operation early next year and will equip the facility for future population growth Stuttgart 21 consists of two projects: 'S21 – reconstructing the Stuttgart rail node' and 'NBL – new build of the Wendlingen to Ulm line' The aim of the former is to transform the existing terminus station into a through station 12m underground thereby connecting Stuttgart to the European high-speed rail network from Paris to Budapest and freeing up valuable real estate The latter project will cut travelling time from Stuttgart to Ulm in half Instead of the current track next to the river through built-up areas in the Filstal is designed for maximum speeds of 250 km/h Stuttgart 21 was first presented to the public in 1994 and it is expected to be completed in 2019 The project has proved hugely controversial Those with long memories may remember Professor Gerhard Heimerl enthusiastically stating on television that it would hardly cost anything because of the 100 hectares of prime building land which would become available in the cramped heart of the city By the time construction finally got underway in 2010 costs were estimated at four billion euros but these have since risen to 6.8 billion euros and are expected to rise further still Whereas the question of who will end up paying for the cost overrun – perhaps inevitable with this kind of project – will rumble on and its significance for years to come seems beyond dispute the one-and-a-half-hour journey from Stuttgart to Herrenknecht AG in Schwanau passed quickly with a welcome packed lunch and animated discussions is one of the typical owner-run engineering businesses which are the backbone of the German economy However its achievements in just 35 years are outstanding in that it has become the worldwide market leader in tunnelling technology The scale of Herrenknecht AG's operation was brought home by a state-of-the-art animated display wall By touching any one of the hundreds of different pictures all the details of that particular project no less than eight Herrenknecht tunnel machines (six Earth Pressure Balance Shields & two Mixshields) are being used by three consortia for the high-speed Crossrail project in London For the 10km long Filder Tunnel near Stuttgart a 10.82 diameter multi-mode tunnel boring machine (TBM) is being used It is followed by a TBM for the Bosslertunnel and two for the so-called Albvorlandtunnel (all EPB-Shields) The largest boring machines made to date are up to 19m in diameter; an arch of this size has been placed in front of the Finance Building to help visitors visualise the scale of such equipment After a tour of some of the production shops at Herrenknecht and closer inspection of various TBMs currently under construction in the open air the visit ended with some people returning on the coach to Stuttgart while others chose to stay on in the Baden region over the weekend to enjoy the delights of this wine

Now tested and disassembled, the TBM is ready for its trans-Atlantic journey to the line's launch shaft, currently being excavated at McCowan and Sheppard. Over the last few weeks, the dismantled TBM has been loaded into containers and shipped via barges along the Rhine River to the Dutch port of Westdorpe. From here, it will depart on Friday, Nov. 26, crossing the Atlantic Ocean as part of a 6,300-kilometre trek to Toronto.

But what kind of ship do you need to get a 2,000-tonne behemoth across an ocean? A Dutch heavy load cargo container ship, aptly named Jumbo Vision, is the perfect ship for the job, with an impressive carrying capacity of almost 7,000 tonnes. That's the weight of almost 4,000 average-sized cars. Jumbo Vision being loaded with containers full of TBM parts at the Dutch port of Westdorpe. Photo by Strabag via Metrolinx. Jumbo Vision's approximately two-week voyage will depart Dutch shores on Friday, but there will be more updates as the giant TBM makes further progress. The next big update will occur when Jumbo Vision passes through the St. Lawrence Seaway and arrives in the Port of Oshawa in mid-December. From there, the shipping containers carrying the goods will be trucked to the launch site, assembled, and lowered into the ground for a spring launch.

The Scarborough RT is expected to close in 2023, and Scarborough residents will have to go years riding replacement buses before the new subway extension opens, currently scheduled for 2029-2030.
