    İSKİ is special. İSKİ supported a company to build first Turkish tunnel boring machine. Arcan Makina (ARM) buılt first Turkish TBM some years ago. Güçlü İnşaat used it to bore a tunnel in İstanbul.

    Arcan Makina was a small company. Very small company. Because of German and China invasion, it bankrupted and closed unfortunately.
