Jubilee Line Extension
The Jubilee Line Extension was significant on a number of levels. Not only was it one of WJ’s first projects with London Underground, but it was also one of the first instances in the UK of in-tunnel inclined wellpoint dewatering – a service WJ have used successfully at many sites since this project!
WJ have a long record of working on the London Underground network, and the Docklands Light Railway extension from Greenwich to Lewisham was one of the first projects we provided our dewatering expertise too. In order to extend the line from The City of London on the northern banks of the Thames to Greenwich on the south banks a tunnel was constructed and WJ installed a combination of deepwells (installed from a barge in the river, with pumps installed by divers!), in tunnel wells points and sump pumping to enable the construction works.
From the early 19th century until the middle of the 20th century, the Canary Wharf area’s iconic docks were some of the busiest in the world. Following their decline, the area has undergone substantial regeneration to become one of the main financial centres of the UK. During its constant regeneration WJ have provided a range of groundwater management solutions to dozens of projects across the whole estate. The first of these was in the early 1990s, and to this day is one of our most active parts of the country for dewatering projects.
Dubai Airport Terminal 3
The construction of Dubai’s International Airport Terminal 3, was at the time, the largest excavation WJ had ever dewatered, covering over 420,000m²! The innovative ‘underground’ nature of the terminal buildings, with the airplanes overhead, meant dewatering would be required on a scale WJ had not undertaken before, especially not in the new unfamiliar climes of the Middle East, but as ever we rose to the occasion!
The Crossrail project was the construction of the new 118km long Elizabeth Line through Central London to compliment the existing London Underground network. WJ were engaged to undertake surface, shaft and in-tunnel dewatering for the construction of the new stations, running tunnels, cross passages and access shafts.
Polish Office Opened
WJ were long established in the UK, and the Middle East when we expanded in to Europe in 2012 with the opening of our Polish office in the country’s third largest city, Lodz. The office was opened to help manage the Lodz High Speed Railway Interchange project, and since then has successfully managed nearly 100 projects in the country.
The Thames Tideway project is the construction of a new 25km long ‘super sewer’ through central London, to reduce the pressure on the existing Victorian sewer network. Due to our expertise, WJ were engaged to undertake pumping tests and dewatering works on a number of sites across the proposed scheme including works at iconic locations such as Blackfriars, adjacent to Battersea Power Station and along the Victoria and Albert Embankments.
Eglinton LRT Metro, Toronto
The Eglinton Crosstown Light Rail Transit (LRT) project consists of a 19.7km light rail system running through the heart of Toronto from Mount Dennis in the West to Kennedy in the East, and was the first major project won by WJ in North America. Using the considerable expertise WJ had gained from working on Crossrail and various other TfL projects in the UK, we were engaged to provide dewatering for a number of station, cross passage and running tunnel excavations across the proposed network.
Galata Port, Istanbul
Istanbul, at the mouth of the Bosphorus, has long acted as a gateway between Europe and Asia. The Galata Port was first constructed in the late 19th Century to first service trade in to the Black Sea, and then subsequently for tourism. WJ were engaged to provide dewatering and groundwater management for a number of the initial redevelopment phases, which will eventually provide improved tourist facilities, a new waterside promenade and the regeneration of existing historical buildings.
WJ’s presence in the Middle East was further enhanced with the opening of new offices in Kuwait, complementing our existing operations in Qatar and Dubai. The office was initially opened to help manage the Al Zour LNG Terminal project, but will be our base of operations in the country for years to come.
Al Zour LNG Terminal, Kuwait
The Al Zour LNG Terminal project was WJ’s first foray in to Kuwait. A logistically and technically challenging project because of the size of the excavations, and the restrictive working hours was successfully completed and demonstrated WJ as being one of the most reliable and adaptable dewatering contractors in the Middle East.
