On the historical site of the Al Maktoum Hospital, this re-development included construction of three neighbouring buildings and a great solution from WJ Groundwater.
The basements of the three buildings were constructed within one large irregular shaped excavation with a perimeter of approximately 1,200m. The excavation was up to 9m and was supported by secant piles around the perimeter.
WJ worked closely with the piling specialist Stromek Emirates Foundation LLC to come up with a dewatering solution that meant that the deepwells could be located in the indent of the secant piles. This meant that the deepwells were kept outside of the footprint of the proposed basements, removing the requirement for complicated structural and waterproofing details. This also made protecting and maintaining the dewatering system simple as they could be accessed from the top of the capping beam.
The project was a great success and this was another example of how good dewatering design and thoughtful implementation can maximise programme and commercial savings.
