30% of New Zealand’s water usage comes from groundwater, the integrity of which is critical to the health of our environment, our population and our economy. With so much of our development occurring in coastal areas, the effect of rising groundwater is a major issue that cannot be ignored.
This is especially important for high-end developments on small sites in highly sought after areas – where space is at a premium. To maximise the potential of building land, underground development is increasing so it is essential to understand the latest methodologies and technology and how these reduce the cost and delays of underground projects.
At the end of May, the 6th Annual Infrastructure & Deep Foundations Conference is being held in Qatar where, since the announcement that the Gulf state will host the 2020 Soccer World Cup, it is expected that over US$350 billion will be spent on construction.
This year’s conference aims to illustrate innovative solutions to underground infrastructure and deep foundations and of particular interest will be the address on ‘Assessing the efficient control of groundwater through dewatering systems’ by Karim Roshdy, Resident Engineer for AECOM. Roshdy’s paper will explore:
- Suitable dewatering systems to manage high groundwater levels in construction such as well points and deep well systems
- How to effectively minimise the dewatering effect on adjacent structures through the use of recharge wells and barriers
- Dewatering subsidence and how to eliminate it effectively to meet environmental standards
