Suttle Projects wins Network Rail scour protection subcontract worth £1.4M

Suttle Projects, the sheet piling contractor arm of Dorset-based Suttles group, has been awarded a scour protection subcontract deal worth £1.4M by construction firm Osborne. 

The contract covers maintenance to eight rail over river bridges across Network Rail’s Wessex Route for Osborne. 

The scour protection work is required on the eight identified bridges to elongate the life of the structures and to stop further erosion of the riverbeds.

Suttle Projects will carry this out by creating cofferdams using sheet piles and over pumping using high capacity pumps, or diverting flow, depending on the rivers’ characteristics. Once this temporary dry work environment is created, repair work will be carried out on the bridges together with any associated works.

Joe Paine, director of Suttle Projects, said: “We have worked on many similar Network Rail scour protection projects over the last few years, although one of the eight bridges in this contract needed a specialist solution. 

“The bridge in question has less than 2m headroom, with deep, fast flowing water. Traditional sheet piling techniques would not be ideal for this set-up, so we have created our own underwater remote control excavator with the cab and engine removed so that it can be floated under the low headroom bridge on a pontoon, and operated by remote control.”

Steve Carr, project manager at Osborne, added: “Suttle Projects have been awarded this contract due to their in-house knowledge and experience. They are also very keen to get involved with the design process, making sure that the proposed solution is practicable and can be installed.”
