Finch West LRT Project, Toronto

The Dewatering Vendor of Choice for Toronto LRT Projects

The success of the Eglinton Crosstown LRT (Light Rail Transit) project (also known as Line 5) in Toronto, where we have provided dewatering services to great effect on 12 of the 14 stations, has led to WJ becoming the dewatering vendor of choice for large LRT projects in the city.

Finch West Station

The Finch West Station includes a deep connection to the existing subway station and an underground track crossing – in short a deeply complex project, that will require the installation of deep wells, wellpoints and eductor wells. Fortunately these types of projects are second nature to WJ and perfectly demonstrate our creative and flexible approach to providing successful and efficient dewatering solutions that we have shown on thousands of project in Canada and elsewhere across the globe!

Humber College Station

The Humber College station, located adjacent to Highway 27 will be another opportunity to demonstrate many of the dewatering techniques that were used to great effect on the deep excavations of the Eglinton Crosstown project.

Finch West LRT

Building on the success of this project, WJ have recently begun work on the Finch West LRT project. The Finch West Project (also known as Line 6) continues the expansion of public transit services in Toronto and is expected to carry some 40,000 passengers per day by 2031. Our initial works on the project will cover the two new underground station that are due to be constructed: the new terminus at Humber College and the new interchange terminus at Finch West, where the new line will connect with the Line 2 extension to York University.

We are proud to be given the opportunity to contribute to this exciting project, and the continued expansion of public transit projects in Toronto, and look forward to its successful completion, and having the opportunity to hop on board!

New Tottenham Hotspur Stadium

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.

Lusail Expressway

Lusail Expressway is one of the largest among 30 road projects to be developed as part of Qatar’s seven-year Expressway Programme.

Initiated in 2010 to connect people and places across the city of In 2010, Qatar’s seven-year Expressway Programme consists of 30 road projects, with the aim of connecting people and places across the city of Doha and wider Qatar. Nine hundred (900) kilometres of new road network involving a number of underpasses, flyovers and multi-level interchanges are expected to be delivered.

The Lusail Expressway is one of the biggest to be developed, with 5.3 km of four-lane highway in both directions, two cofferdams and three major interchanges; the Al Wahda Interchange, Onaiza Interchange, and the Pearl Interchange.

The Expressway will also have two service lanes in the multi-level interchange areas, and include a complex network of tunnels, flyovers and junctions in order to meet the future traffic demands by providing easy and speedy connectivity.

Dewatering of the project proved a challenge, as unforeseen and unexpected cavities and fissured flows were encountered, with at the peak flow in excess of 10,000 m3/hr for one of the underpasses! However, WJ rose to the challenge and dewatering was achieved with deepwell system and supplemented with sump pumping.

Dubai International Airport Terminal 3 and Concourses

Neil.Coulter May 25, 2016

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.
