Dredging activities can even be performed in other parts of the world. It is possible to send the contractor’s own equipment including cutter suction dredgers, hopper dredgers, and even heavy stationary dredges.

The dredging activity is continuously monitored and surveys are performed to ensure that the dredging activity carries on as planned. Dredgers themselves have onboard monitors for accurate dredging location, position, and alignment.

Each new survey offers updated guidelines and it’s integrated into the dredger’s onboard system. In order to constantly evaluate the project’s development, there are constant surveys performed to provide data about the dredging area.

Work supervision ensures that there are clear records in terms of dredged volumes, dredging sections, and cycles, as well as equipment power. Delays are registered too in case of equipment failure or delays that have to do with the employer.

A good contractor keeps track of the progress through daily and weekly reports. Supervisors mention details concerning project development, as well as volumes, units, surveys, delays, and any other relevant information.

There will also be structured meetings. They will discuss the latest activities and developments.

At the end of the project, there will be a final project report prepared by the engineer. This one will comprehensively describe the dredging process throughout time.   Biological remediation of dredged materials.

The conclusions and further recommendations concerning maintenance will be mentioned too. The annexes will feature related important documents.

The site will be cleared after the contractor successfully completes the project. Then the plant demobilization stage will be completed as well.
