Weymouth Residents Warned Over Noise from Harbour Wall Repairs
7:42am 17th January 2013
It's going to get noisey in Weymouth.
Piling work to repair the harbour wall starts on Monday 21st January and the Council are warning us to be prepared for noise disruption.
15 meter hallow steel tubes will have to be driven into the ground.
Contractor Balfour Beatty say they'll do all they can to limit the noise.
The piles used by contractor Balfour Beatty for these works are a combination of 15.5m-long hollow steel tubes and steel sheets that are driven or hammered into the ground to form deep foundations for the harbour wall.
Each tube is connected to the steel sheet piles to form a box which is then strengthened with tie-rods, before being filled with compacted quarry material. Finally, a concrete capping beam and fenders plus tarmac surfacing is then placed on top to create the new harbour landing.
The piles will be driven in using a vibratory hammer and once driven as far as they will go an impact hammer will be used to push the piles in further to their designed embedment depth.
Cllr Gill Taylor, Brief Holder for Environment and Sustainability at Weymouth & Portland Borough Council, said: "We are really pleased that work to repair the harbour is progressing well and as planned. We are now moving to the next stage of the project and would like to make residents aware that there could potentially be a lot of noise during the piling stage of the works.
"This has to be carried out to get the works done and will be worth it in the long run as it will enable Condor Ferries to return to the borough.
"The contractors Balfour Beatty, and the staff from the borough council who are involved in this project will limit noise as much as possible, however noise associated with this type of work is unavoidable and we would ask residents to bear with us during this phase."
Scour protection works on the sea bed will take place in March and April.
The scour hole, a hole created through the removal of particles on the sea bed over time, will be repaired by partially filling with quarry fill and a protective mattress placed on top to stop the hole from redeveloping.
The schedule for the works is tight with a number of project risks including poor weather, potential issues with removing old piles and obstructions when driving new piles in.
The working hours agreed between the borough council and contractor are Monday to Saturday 8am-6pm.
Some operations are tidally affected so may require work outside these hours.
The borough council will keep people informed of any other work outside these hours or other potential disruption.
Structural changes were detected to harbour wall berth 3 in February 2012 and emergency work to secure a short-term fix was unsuccessful.
Advanced works during the summer helped to stabilise the wall in preparation for the main works.
Balfour Beatty Civil Engineering was appointed as contractor in October 2012 to carry out the repairs.
Condor Ferries announced its fast ferry service will return to Weymouth on 17 July 2013 as part of its 2013 schedule, once works to fix the harbour wall are completed.
