Underground Construction Challenges in Urban Areas
Urbanisation presents geotechnical engineers with the challenge to build safe and sustainable infrastructure where the available construction space above and below ground is becoming more and more congested.
Such is the case for Singapore, where for example most of the upcoming extensions of the railway lines into the city centre are planned to run underground. This presentation will cover the engineering assessment methodologies typically followed in Singapore, to assess and manage the impact of excavations and tunnelling on adjacent infrastructure and buildings. Some examples from recently completed underground spaces will be presented, with discussions around key design and construction challenges and how predictions compared to actual performance on site.
