A9 1360 Cromarty Bridge Scour Repairs

Date: May 10, 2021

We are delighted to have been retained by Transport Scotland and Bear Scotland to perform further Scour repairs to the A9 Cromarty Bridge. Our appointment follows a previous project completed in 2017. The project involved scour repair works to six piers. Our scope of work included:

  • Excavation of the seabed around the pile cap to the required formation level and slope
  • Installation of geotextile to be situated on the dredged surface profile and around the pile cap where specified
  • Placement of rock armour on the geotextile in the dredge cut, starting from the revetment toe and building up to the underside of the pile cap
  • Pumping of backfill material into the voids where present under the pile caps, with pumped material secured by geotextile and rock armour
  • Placement of excavated seabed material at the toe of the rock armour to seabed level

All works were successfully handed over on time and to budget.
