ABSTRACT
In general, a coastal structure is planned as a practical measure to solve an identified problem. Starting with identification of the problem, a number of stages can be distinguished in the design process for a structure: definition of functions, determination of boundary conditions, creating alternatives, geometrical design and the final choice of functional solution. After the choice of functional solution has been made the structural design starts including creating structural alternatives (i.e. using different materials and systems and various execution methods). The final choice will be made after verification of various structural solutions in respect to the functional, environmental and economic criteria. Design stage including the making of alternative designs is the most important stage in terms of the project costs. After the final choice is made the possibilities of saving project costs are very limited. It stresses the importance of making of alternative design and the proper choice of the final solution.
