Tunnelling and Underground Infrastructure: A Practical Training Course in Ground Assessment, Design and Risk Control (Online / Remote)
1Summary
Cities running out of surface space, and transport networks crossing mountains or rivers, increasingly rely on one solution: going underground. But driving a tunnel through rock or soil means confronting geology, groundwater, structural loads and safety risks that change from one metre to the next. This Tunnelling and Underground Infrastructure training course by Arab British Fellowship Training Academy walks participants through that full journey — from reading ground conditions, to choosing an excavation method, to designing, building, monitoring and keeping a tunnel safe throughout its operational life.
Positioned within the Construction and Civil Engineering Training course specialization and classified under Engineering maintenance and operation, the programme builds working knowledge of geotechnical engineering, modern tunnelling methods and underground construction practice. Participants leave able to assess ground and groundwater conditions, choose and apply suitable excavation and support techniques, control construction risk, and manage tunnel performance across its lifecycle.
2Objectives and target group
