This European Standard deals with underwater excavation and hydraulic placement of fill material for land reclamation projects. The scope is limited to soils that exhibit free-draining behaviour during and after placement. The main purpose of this European Standard is to ensure that functional requirements and specifications for such projects are in harmony with site boundary conditions and construction methods. This European Standard specifies minimum requirements for site related data to be acquired before the procurement and execution stage of a dredging and land reclamation project. This European Standard gives guidance on how the selection of the dredging equipment shall be undertaken. It also gives guidance on the selection of a borrow area and on the judgement regarding the suitability of the fill material for the project. This European Standard offers the general principles on how to design the actual execution of a dredged hydraulic fill project and offers guidelines for monitoring and quality control of that execution in order to guarantee that the fill mass exhibits the behaviour as intended by the designer of the land reclamation. This European Standard does not cover dredging and/or placement of rock, mine tailings, mineral wastes and contaminated soils.
