Overview

Gain insight into tunnel maintenance as the presentation contrasts key considerations for designers/constructors with maintenance regimes over tunnel operational service life.

Focusing on the interface between tunnel systems is key to meeting design life requirements and ensuring a maintainable fit-for-service underground space.

The presentation will look at case studies both locally and internationally, as well as provide insight into what systems are in place for tunnel maintenance after a project is handed over to the operator.

Learning outcomes

You will gain insights on the general complexities with writing O&M manuals for civil aspects. This includes consideration for durability, access, frequency, interpretation of design intent, defining what is reasonable for maintenance and determining whether it can be reasonably completed.

• Tunnel linings, seepage and anchors.
• Cable trays and infrastructure.
• Vent stations.
• Cut and cover areas.
• Drainage systems (groundwater and stormwater).
