Abstract: The growth of many of today’s megacities has been unplanned, spontaneous and uncoordinated. The aim is to improve the living conditions and quality of life. Mechanized tunnelling technology can assist with the rapid implementation of major projects to develop the infrastructure necessary to achieve these improvements. The Grand Paris Express currently ongoing in Paris is an example of a...
Abstract: Greater Stockholm is one of Europe’s fastest growing regions. This stimulates the need to invest in projects to secure sustainable energy supply and to improve the quality of life and living comfort for Stockholm’s citizens. The Stockholm City Link project is one of these big individual projects that will help to meet this need. It consists of a 5m-diameter cable tunnel that runs about 14km...
Abstract: In 2008 the first Deep Tunnel Sewerage System (phase 1) was completed and implemented in Singapore. The concept of the DTSS involves deep tunnel sewers that convey waste water by gravity to centralized water treatment plants. The system is an efficient and cost efficient solution to meet long term needs for waste water collection, treatment and disposal. Seeing the demand today especially in...
Abstract: Sustained economic growth in almost all Latin American countries in recent years has created a favorable constellation of interests for the development of South American transportation and energy infrastructure that has not be seen before. In Panama City a light rail line will be constructed that will be the first of its kind in Central America and will help to alleviate traffic congestion in...
Abstract: Until recently, all rail tunnels in Norway were excavated using drill & blast technology. The Follo Line project is a new 22 kilometers long double track rail line that is currently under construction between Oslo Central Station and Ski. Four double shield hard rock TBMs with an excavation diameter of 9.96 meters excavate a total of about 36 kilometers of predominantly Precambrian gneisses...

Abstract: With the first use of a 6.24m-diameter Mixshield TBM for the Metro Moscow in 1987, the way was paved for a successful market entry of German manufactured mechanized tunnelling equipment in Russia. Another 13 years passed before re-entering the market in Russia with the contract for a 14.2m-diameter tunnel boring machine (TBM) for the Lefortovo road tunnel in Moscow. Since then Russia has...
