N2 - Field performance of a shielded slurry microtunnel boring machine used for installing concrete pipelines in four different project sites in Istanbul is presented in this study. Herrenknecht AV N 1800C machine is used for installation of the wastewater pipelines. Brief descriptions of the projects are presented. Geological conditions and formations varying from rock to water-bearing sands and silts that the machine passes through the project sites are described briefly based on in-situ and laboratory site investigations. Field performance of the machine is summarized based on field observations and records, such as average system utilization and net advance rates, as well as downtime. The results demonstrate the success of microtunnelling to cope with varying ground conditions, which influence the boring performance to a great extent, without disruptions to the surface and underground utilities.
