Client: Morgan Sindall/National Grid Duration: 9 weeks Value: £1.2m

Kaymac win £1m contract with Morgan Sindall/National Grid River Mersey, Carrington river bank scour protection works, Manchester.

Approximately 4,400 tonne of rock armour is to be placed into the river bed and bank to protect the existing National Grid tower structure located close to the river Mersey, Carrington, Greater Manchester.  Designed by JBA the method involves excavating down to a predetermined formation level then installing a double layer of rock armour, providing uniform protection along the length of the affected embankment. The higher level of the embankment would be protected using a mesh based geotextile to reduce costs and promote vegetation growth. The works are to be carried out in wet working conditions, in this instance as it is not practical to de-water or divert the watercourse, Kaymac are UK leading specialist in working in wet environments and have over three decades of experience in working in this kind of environment.  Our commercial divers will be required to install environment protection mitigation measures to protect the watercourse and environment downstream, and also undertake measures for managing various forms of invasive species present on this site including separating, transporting and stockpiling arising in designated areas within the site. Kaymac have previously collaborated with Morgan Sindall, National Grid and JBA Consultants in past years, and we look forward to together again on this prestigious and much needed project.
