Softening works in the area owned by A.B.S. steel-making plant are part of a program for the construction of environmental protection and greening works. The area involved by the project surrounds the enterprise for about 127,000 sq.m westward, about 100,000 sq.m southward and about 6.000 northward. This design has accomplished a work of geometrical and morphological arrangement of the grounds around the plant so as to make the surface layer suitable for afforestation. In these areas the ground level has been raised up with results that improve the plant screening, so as to produce a sound-absorbing effect and a softening of the landscape. The functional model of the raised levels has been made with reinforced ground terraces assuring better stability of the work.
