King Sheet Piling (KSP) was first used in 2009 on this prestigious, high-profile and fast-track project to widen 63 km of motorway in the northern sector of the M25 London Orbital Motorway. Introduced without prior trial, it proved a resounding success, with over 25km of KSP wall forming part of Europe’s largest land-based use of sheet piling. Steel saving of 35% to 40% was typical. The KSP installation speed was key to the project opening 3 months early and helped deliver KSP savings of over £10M, shared equally with the Highways Agency.
Incorporation of KSP in 2009/2010 in the re-design of a pumping station saved £800k and avoided a projected 3 month programme over-run, resulting in savings of £2.7m for Client, The Highways Agency.
KSP’s versatility was proven in 2011/2012 by use in weak rock where sheet piles would normally be rejected. It saved valuable vegetation screening, enhanced safety and was built in 1/3 the time of a gabion alternative.
KSP was used to great success in stabilising a railway embankment for Network Rail, saving 41% of steel and more than halving noise for nearby residents.
18 April 2018: February saw the start of KSP installation on the A14 Ellington to Fen Ditton highway project. Planned other UK Smart Motorway work this year using KSP walls includes the M1 Jnct 23A-25, M6 Jnct 2-4, M4, Jnct 3-12, M1, J13-16 and M23 Jnct 8-10. Last summer saw completion of KSP walls on M1 Jnct 19-16, M25 Jnct 30 Improvement and M5 Jnct 4A-6.
