While planning the infrastructure of your projects, it is paramount to know that laying out the pipeline and ducting systems for utilities (such as waste water, gas, electricity etc.) does not have to involve excessive surface disruption or invasive excavations Micro-Tunneling.
Micro-Tunneling is a trenchless, remotely controlled, precise tunneling technology that allows you to lay your pipeline systems without breaking ground, disrupting the outer landscape and environment, or requiring costly and labour-intensive interventions.
This paper outlines the systems that are involved in Micro-Tunneling, and discusses the principles involved in this process. It also explores the technical requirements of the system as well as the various geophysical and environmental factors of your construction site, for the implementation of Micro-Tunneling. This information is made available for the convenience of those in the field of civil and transport engineering and statutory undertakers, to help make informed decisions in project planning.
If you often find yourself wondering if Micro-Tunneling is the pipeline solution your construction project needs, download this paper to make an educated choice.

Micro-tunnelling is a trenchless technology method used for installing new pipelines. The inherent advantages of this method over open-cut trenching have led to its increasing use since its first introduction in the early 1980s. With this technology, surface disruption can be minimized, especially in urban areas, and high accuracy of installation (usually less than 2cm over 100m) can be achieved in both line and grade.
But micro-tunnelling machines are very expensive, and few contractors have extensive experience with this technology. Micro-tunnelling can also be risky when unexpected obstacles or soil changes occur. Careful constructability analysis is needed, and an appropriate micro-tunnelling method should be selected to achieve the successful completion of micro-tunnelling projects. A series of tables for micro-tunnelling are included to support decision-making for contractors who want to bid on micro-tunnelling projects. When the user checks basic information about the potential project such as drive length, installation depth, pipe diameter, and soil condition, the tables will give you adequate information to be able to evaluate whether micro-tunnelling will be economically feasible and suggests appropriate types of micro-tunnelling equipment. The user can then select micro-tunnelling machines, types of pipes, and types of shaft construction methods. This paper will be most beneficial when used at the preplanning stage by utility contractors.
