March 22, 2017 –  Freelance journalist, Roland Herr, authored a very informative piece titled “Tunneling in Turkey — Lovsuns Supplies TBMs for Metro, Wastewater Tunnels in Istanbul”, posted on tunnelingonline.com.

In the article, Herr starts off mentioning Lovsuns’ delivery of a 6.5m TBM, a refurb used in the Toronto-York Spadina Line extension.  He then goes on to detail the scope of Istanbul’s Metro project, which he says “is undergoing a massive extension with more than 70 stations and over 330 km of route under construction”.  He also goes into great detail about the challenges of boring through a very narrow and densely populated urban environment, as well as, planning for the different types of geological materials found in Fulya, Yildiz, Besiktas, and Kabatas.

Herr quotes Tunnel Manager Yigit Gencay in saying:  “Our EPB TBM from Lovsuns provided the perfect counter-balance between ground conditions and ground water with the cutting shield.”
