Abstract [sv]

This is a diploma thesis executed as a part of the examination of the educationalprogram Building engineer – Construction management at Halmstad University. The aim of the thesis is to compare and evaluate conventional open-cut pipe-laying withhorizontal directional drilling. The thesis includes a comparison of the economic,environmental and time-based aspects of both methods and discusses which factorsthat determine the optimal choice of method.The study is mainly based on previous studies regarding the subject and oninterviews with professionals from the industry.A fictional project with five realistic cases of pipe-laying scenarios was compiled,sent to different companies for calculation, evaluated and compared. Our conclusionregarding when it’s suitable to use which method is entirely dependent on thespecific project. The different methods each have specific pros and cons and shouldbe evaluated regarding the projects economic, temporal and environmental demands.In bigger projects we see that a combination of the two methods can be suitable.

Keywords: Horizontal directional drilling, trenches, open-cut trench methods,excavation, conventional trenches, pipe-laying, economic analysis, environmentalanalysis, time-based analysis
