Some Observations on the Economics of 'Overdesigning' Rubble-Mound Structures with Concrete Armor.
Abstract
A cost comparison is made between two designs for a revetment-breakwater using concrete armor units. Both designs used the same type of unit (dolosse); however, two different stability coefficients were used in the designs. The comparisons shows that significant decreases in armor unit size may result in only insignificant cost savings and even cost increases for some conditions. This occurs because more smaller units are required to armor a given structure surface area, and any savings in material costs is offset by the increased cost of forming, stripping, and placing a greater number of smaller units.
