This course is run exclusively by the American Society of Civil Engineers (ASCE), the internationally recognised leader in training for engineers and technical professionals.
Thanks to technical advances and increases in the utilisation of microtunneling over the past decade, small and medium diameter pipes are today being installed in virtually all ground conditions with a minimum of surface disturbance. Despite this shift in technology, microtunneling techniques incorporate many of the complexities and technical challenges of modern large diameter tunnels.
This three-day course is tailored for those interested in microtunneling and describes and reviews the technique in depth. It makes comparisons with other trenchless techniques such as horizontal directional drilling and discusses techniques for subsurface investigation and characterisation.
The course also examines the selection, sizing and construction of various shafts for tunneling, and key aspects of microtunnel design, specification, planning, monitoring and management, including risk assessment and management, as well as new trends and the state of the art in microtunneling.
Upon successful completion of the course, you’ll be able to understand and specify the microtunneling method most suitable for a given set of soils, groundwater, tunnel diameter and depths. You’ll also be able to plan and specify a microtunneling project and understand the performance envelope for microtunneling.

Andy Robinson has a B.Sc Civil Engineering degree from Aston University in Birmingham, UK and has over 30 years experience in the underground utility installation sector. His primary experience is in the fields of tunneling, underground space and trenchless technologies including tunneling, pipe jacking & microtunneling, Horizontal Directional Drilling, shaft works and jacked underground structures.
Andy specialises in underground design, construction management and Expert analysis and prior to entering the engineering services field had roles with both a tunneling contractor a tunneling plant manufacturer. His expertise covers all aspects of project development and support, from project evaluation and feasibility study through conceptual and detailed engineering design to equipment and materials selection, project construction and operations management, and dispute resolution. He has a strong practical understanding of geotechnical and geological conditions and their impact on the underground works and how they are constructed.
His international experience is extensive having worked on projects in Europe, SE and Far East Asia, North, South and Latin America, The Caribbean, the Middle East and Australasia. He has been at the forefront of developments and innovations in the trenchless technology, microtunneling and tunneling field and has been a team member on two projects that have previously been recipients of the Trenchless Technology “Project of the Year” award.
You will learn the following:
Topics covered include:
Sub surface site characterisation in soil and rock for microtunneling
A review of the techniques for investigating and characterising subsurface conditions for both soils and rock will be presented and particularly how these are applicable to microtunneling.
Microtunnel methods used in construction
Tunnel construction methods using microtunneling and pipe jacking techniques will be examined in detail. Site layouts and planning for microtunneling in various soil types, alignment control and tolerances, jacking forces and the use of interjacks are included.
Microtunnel jacking pipes and segmental linings
Types of jacking pipes available for microtunneling will be presented together with a review of their appropriate use. The use of segmental linings in microtunnels will also be covered. Key factors in selecting and specifying microtunneling linings will be addressed.
Shaft construction for microtunneling
A discussion of shaft construction techniques, their selection and merits in various ground conditions and shaft depths.
Planning, productivity and costing for microtunneling
Project development, planning and productivity including key factors for microtunneling will be discussed, as well as shaft locations, drive lengths and the development of cost levels for microtunneling projects.
Microtunneling pre-qualification, submittals, operational monitoring and safety
Required pre-qualification, specification and other key elements of contract documents for microtunneling together with required submittal information from contractors will be discussed in detail. Recommended monitoring of microtunneling will be described and the interpretation of such acquired data and training of site staff will be reviewed.
Microtunnel management, risk and safety
Key aspects of the management of microtunneling projects will be discussed including risk identification, both technical and commercial risk mitigation measures, and safety requirements.
Potential problems in microtunneling and shaft construction
Problems encountered in the design and construction of microtunnels will be reviewed. The means for identifying potential problem areas on projects and suitable mitigation techniques will be described including case studies.
New development trends and techniques in microtunneling
New trends in microtunneling and potential future developments will be described as well as the state of the art.
Videos of microtunneling in action and case histories
Relevant short videos of the various techniques as well as numerous case histories will be presented.
