10:00 - 16:00 Masterclass: Overcoming Challenges in Design and Construction of Cost Effective Tunnel Infrastructure

(includes lunch and tea breaks)

Rationale:

The cost of tunnel infrastructure, as against bridges, is considered usually higher. Better design standards, technologies in construction and safety standards increase the outlay for the asset owners and developers. Therefore, developing economical and sustainable options in tunnel engineering will make subsurface infrastructure a more viable and attractive option. This interactive masterclass will highlight how this objective can be achieved.

Discussion Points:

• Understanding the need for quality geotechnical investigations
• Trends in evaluation and selecting of ideal tunneling method
• How to identify and select various services involved in tunnel construction
• Sustainable methods in tunnel fi nishing activities
