The need for utility lines with less distraction to the surface increased the demand for trenchless excavation methods. Today, trenchless technologies are one of the fastest growing utility installation techniques in the construction industry. Their demand is on a continuous rise and newer technology is emerging and is being used. Trenchless methods can be classified under three main categories which are new pipeline installation, pipeline replacement; and pipeline renovation. This research studies the auger boring technique and evaluates the construction factors that affect project productivity. Auger boring is a process that involves a large number of factors that need to be considered for productivity prediction and improvement. This research utilized two simulation techniques to simulate the auger boring process and evaluate the productivity of auger boring systems. It studied the effect of various bore length on project productivity and cost as well. The two simulation models were developed using MicroCYCLONE and Arena. Data was collected using a questionnaire that was sent to a number of auger boring contractors in the Midwest. This paper identifies the factors that affect the productivity of auger boring machines and explain the development of the simulation models. Furthermore, the results of the simulation models were analyzed and compared.
