Jackfield Stabilisation

03.04.2014

Following on from the Jackfield Enabling Works project undertaken in the Ironbridge Gorge between December 2013 and March 2014 McPhillips is pleased to have been awarded the main Jackfield Stabilisation Works contract by Telford & Wrekin Council.  The Jackfield area is plagued with unstable ground conditions resulting from its geological composition, which have been exacerbated by mining activities in the 18th and 19th centuries.  The Stabilisation Works contract is designed to address the most active area of ground, enabling replacement of the existing highway between the Tile Museum and Maws Craft Centre which has suffered subsidence over many years.  The site is nearly 1km long and 400m wide and the £8.8m main contract will run until 2015.  The activities will involve:

  • Construction of main compound area off Calcutts Road, including new access road.
  • Removal of roots from the areas of trees previously felled.
  • General topsoil strip.
  • Treatment of Japanese Knotweed and Himalayan Balsam.
  • Earthworks to form access tracks/ working platforms (‘piling mats’), including placing approximately 300mm of hardcore as a running surface.
  • Drilling and grouting to old mineshafts and to the ground along the pile ‘corridors’, and further ground investigation.
  • Piling to the main slope, between the Jackfield Tile Museum and the Half Moon PH to stabilise the hillside.
  • Piped drainage to the hillside.
  • Earthworks to rationalise and drain the slope topography following the piling works.
  • Vibro-concrete column (VCC) piling to the area between the River Severn and the Maws Craft Centre.
  • Revetment stabilisation works to the river bank between Church Lane and The Boat PH.
  • Re-alignment of Salthouse Road and Salthouse Lane, including the construction of a new junction to make Church Lane a through-road.
  • Associated service diversions and drainage.
  • Re-aligning the redundant section of Salthouse Road and forming an extension to the Severn Valley Way.
  • Construction of various footpaths to the river frontage and general landscaping to the whole of the site as cultural and environmental improvements.
