The project has conducted preparatory work in the area and successfully tested how stones should be laid out. They are now building an underwater jetty/platform with stone masses at the northern end of the Gunneklev fjord.
Transportation of stone masses
There will be some construction traffic in connection with the delivery of stone masses. Large vehicles unload stone masses at the construction site, and then the stones are loaded onto a barge. This operation may generate som noise. Hydro conducts noise measurements and ensures compliance with requirements.
"The stone masses come from NCC Quarry in the vicinity. The project has implemented several measures to ensure safe and efficient transport, and we have a strong focus on health, safety, and the environment," says Eivind Midtgarden and Boško Janjušević from Hydro's project management.
The Hydro project has taken on the task of cleaning up debris in the shoreline along the pedestian and bicyle path. "We do this because we cannot cover the waste that is on the water's edge. There are car tires, shopping carts, and other waste that needs to be removed," says Eivind Midtgarden.
The textile curtain that can be observed a good distance out on the water is a silt curtain. It extends all the way to the bottom and prevents the spread of environmental toxins that could potentially be stirred up when stones are laid out.
Path along the water closed
The pedestrian and bicycle path along the waterfront will be closed during the construction period. Safety is crucial for Hydro, and as long as necessary, the pedestrian and bicycle path on the seaside will be closed during the construction period.
Hydro closely monitors the project, with a strong focus on operations. "We do not rush for time; we prioritise heath, safety, and secure progress," says Boško Janjušević. The goal is to complete the project by December 2024.
"We are very satisfied with the collaboration with the main contractor Repstad Anlegg AS. The contractor works six days a week and has good progress. They are professional, with a clear focus on health, safety, and the environment.
"The environmental measure will ensure that we achieve the overall goal, which is to remove the environmental toxins in Gunneklevfjorden from circulation. By covering the seabed, they will not be able to leak from the sediments and be taken up in the food chain. It will also prevent the spread of environmental toxins to surrounding areas. The solution will provide a clean seabed and form a good starting point for the reestablishment of flora and fauna," says Hydro in the project information to the public.
