    Clients said

    • Very professional and have great technical and practical abilities.

      Con Hogan Project Manager – Anchorsholme, Ward & Burke Construction
    • WJ designed and installed an effective solution to control the groundwater for our basement excavation. Their work was carried out efficiently, safely and to programme.

      Chris Grant Commercial Manager – Scottish Power HQ, Laing O’Rourke, Glasgow
    • Overall the dewatering works were a success and I felt WJ Groundwater were easy to deal with and extremely helpful when called upon. I hope to work with them again in the future.

      Neil McGurn Project Manager – Kyleakin, Careys Civil Engineering
    • WJ designed and installed an effective solution to control the groundwater for our basement excavation and deep core areas. Their work was carried out efficiently, safely and to programme

      Stuart Jackson Project Manager – RHSC, Brookfield Multiplex, Edinburgh
    • Very satisfied with service from the initial site meeting through to demobilisation

      Paul Madigan Operations Director – Chertsey Water Works, Connect Plant Ltd
    • WJ’s installation team was excellent. The dewatering and groundwater recharge system worked as per WJ model & design. The works, including the Groundwater Treatment Plant setup and demobilisation, were carried out according to the programme. We received very good technical support with prompt production of monitoring data & reports.  Of special note was WJ‘s expertise in contractor assistance to mitigate risks for our forward planning.

      Site Agent / Design & Temp Works Manager, Hochtief Murphy JV
    • Great, friendly service. Very helpful and easy to work with.

      Guy Bainbridge Quantity Surveyor – Mickleton, M Lambe Construction
    • WJ provided a very good service, from the start of the proposed works...The drilling team who installed the wells were very hard working under difficult tidal conditions which were based on the 6hr working window in which they worked to a very high standard...Overall it was a good service by your company and i would have no hesitation in recommending to use you in future works.

      Darren Jones Snr General Foreman – Anchorsholme, Volker Stevin
    • We engaged WJ Groundwater to drill the new ground source energy well at UCL as they had successfully installed an abstraction well at the same site in 2014. This section of the work required careful planning to align with the main site activities. The WJ team carried out the works on programme and worked well with the main contractor to ensure that this logistically challenging project was delivered successfully.

      WJ expand in to Kuwait

      WJ have been an established part of the dewatering game in the Middle East for over 15 years now since providing the dewatering for the Dubai International Airport Terminal 3 development back in 2003, with offices in Dubai since 2005 and our Qatar office due to celebrate its tenth anniversary in 2019. January this year marked our expansion in to nearby Kuwait when we were appointed by the Main Contractor HDEC (Hyundai Engineering and Construction) working under the Client KIPIC (Kuwait Integrated Petroleum Industries Company) for the Al Zour Liquefied Natural Gas (LNG) Terminal Project.

      The new terminal is located in the Al-Zour region of Kuwait near to the border with Saudi Arabia, approximately 90km south of the capital Kuwait City, and will include eight LNG storage tanks, each with a capacity of 225,000m3, and associated marine facilities.

      Although the sandy ground conditions were prime dewatering territory, the project had the potential to be particularly challenging. Not only would WJ be working in a new country which always brings with it a steep learning curve, but the structures to be dewatered were far from insubstantial – the intake and outfall structures which our systems were going to target were approximately 500m by 200m in size, and up to 15m deep, and the works would be taking place on land reclaimed from the Arabian Gulf. Fortunately there are few things WJ love more than a challenge!

       

      In order to complete the works in a swift and prompt fashion WJ utilised one of our trusted partners, Trevi, to work alongside our own SM14 drilling rig. In total 62 dewatering wells and 10 groundwater monitoring standpipes were installed for the intake structure, and another 21 for the outfall structure. The initial plans were to install both perimeter and internal dewatering systems to draw the groundwater level down to enable a dry excavation, however the perimeter system proved to be so successful that there was no need for the internal system to be installed.

      Although the works began at the start of 2018 when the temperatures in Kuwait are relatively comfortable, as the project has progressed the day time working temperatures approached the 40⁰C’s and as the Muslim holy month of Ramadan arrived it became necessary for some of the installation works to be undertaken during the night, with only monitoring to be undertaken during daylight hours. This however had no impact upon the expert level of service WJ are known for.

       

      Hopefully this is the start of long and successful times for WJ in Kuwait and helps to strengthen our position as one of the go-to contractors for any technically challenging dewatering project across the Middle East.

      UK Project Update – Anchorsholme Outfall Cofferdam

      WJ are once again showing our technical prowess with another challenging project in Anchorsholme; dewatering a cofferdam in the Irish Sea!

      WJ have been working in and around Blackpool for several years now, having completed the Anchorsholme Park Storage Phase 1 and Phase 2 works for Ward and Burke and the Lennox Gate project for Ward and Burke and JN Bentley, both during 2016 and 2017.

      Our latest project, working with the CH2M HILLVolkerStevin joint venture, C2V+, was to aid the construction of a new 6m by 20m cofferdam in the Irish Sea, directly off the coast from the Anchorsholme Park Storage site. The particularly challenging aspect of this project was the offshore location of the cofferdam, fortunately WJ have undertaken several similar projects to this in recent years in Ipswich and Dover.

      The dewatering system comprised eight 9.5m deep deepwells installed around the internal perimeter of the cofferdam, installed using a rotary drilling rig, in to interbedded sand and clay deposits during February 2018.

      The first technical challenge on this project was the installation of the wells themselves. It was only possible to install during the two 6-hr low tide windows each day, as during high tides the cofferdam would be flooded. During each of these windows it was necessary to pump out the cofferdam, crane the drilling rig in to position, drill, seal off the works so they wouldn’t flood when the tide came back in, and remove the rig from the cofferdam. Fortunately due to the meticulous planning of the works by the WJ Project Engineer, Michael Cummiskey, the wells were all successfully installed during the planned installation period.

      The second technical challenge was also a result of the offshore location. As the cofferdam would be flooded during high tides it was necessary for the WJ control cabin and generators to be located onshore on an existing revetment, above the maximum tide level, with cables running between the cofferdam and the cabins along the beach and existing sea defences.

      Despite the best efforts of the Irish Sea the target drawdown was successfully achieved and the pumping is due to continue until the end of April.
