White Hart Lane, in North London, was the home of Tottenham Hotspur FC for 118 years and during that time played host to some of the worlds greatest footballers before it was decided in 2017 that a new 62,000 seater state-of-the-art stadium, the biggest club stadium in London, would be built to replace the existing White Hart Lane ground.

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.
Dubai, iconic for its high rise buildings including the World’s tallest building, the Burj Khalifa, is the business hub and holiday destination of the Middle East.
To build itself as major transport hub for passengers and cargo travelling across the globe, in 2002 Dubai’s Department of Civil Aviation (DCA) initiated construction of the Dubai Airport Terminal 3 building and concourses 2 and 3. It covered a massive area of 750m by 500m and was excavated up to 25m deep. When it was completed in 2008 the Terminal 3 building was the largest building in the world per floor space and is currently the largest terminal in the World. The Terminal 3 iconic building is constructed to look like an aeroplane wing, and initially was exclusively for Emirates airlines.
To help realise this fantastic engineering ambition, WJ Groundwater were, of course, brought onto the team.
To facilitate the excavation works in the dry, WJ Groundwater used its considerable experience dewatering large scale project in Europe installed a large scale dewatering system. A key selling point of WJ Groundwater’s solution was that despite the sheer scale of the project, all the deepwells were installed around the perimeter of the site. This meant that the Main Contractor could get on with the excavation and construction works without having any obstructions. At peak construction WJ were operating in excess of 200 deepwells as well as a fully automated data logger monitoring system that allowed WJ and their clients to monitor water levels across site in real time from a website.
WJ Groundwater is very proud of their achievements and is honoured to have worked on such an iconic project.
