Cost Pressures Faced By Thames Tideway Tunnel

    The holding company of the construction of the super sewer of London has confirmed that the project has experienced some cost problems because of a catalogue of engineering challenges.

    Various cost pressures have been identified on the Thames Tideway Tunnel project. The total project costs for the six months to the end of September has already hit £325.3 million and it brought the total cost to £1.48 billion so far.

    Bazalgette, the holding company of the said project, stated: “Following significant progress on the project and now having mobilised on 20 of our 21 sites, Tideway has identified several cost pressures in the programme…to mitigate the cost pressures Tideway has begun to implement cost-saving measures in partnership with our contractors and remains focussed on achieving the baseline target.”

    The saving measures that were outlined in the half-year results of the company include eliminating overlap, taking measures in order to increase productivity, value engineering, and delivering overhead savings.

    Apparently, the areas that are causing the problems are the engineering challenges that are experienced at Blackfriars, construction at King Edward Memorial Park and Albert Embankment, and challenges the challenges in shafts at the east area sites.

    The 25km tunnel is expected to be completed by 2023. It is budgeted to cost at approximately £4.2 billion in total.

    It was granted planning permission in 2014 and has been designed to help the capital in coping with the demand of its increasing population.

    The Thames Tideway Tunnel is considered as the biggest infrastructure project that the water sector of the United Kingdom has ever seen. Dubbed the “super-sewer,” it will be running from Acton, west London and it will run underneath London and transfer waste to the east at Beckton Sewage Treatment works.  It is aimed to help in tackling the problem of the overflows from the Victorian sewers of the capital and protect the river from the increasing pollution for at least the next 100 years.
