The project involves the production of an assembled truss using CNC techniques for the construction of the colonnade of the Palace of the Aegean. The design was based on the existing impressions of the surviving trusses.To produce them, the casting of 56 architectural members with different curved parts is required, which are sequentially placed on a fixed base for flexibility in construction with maximum precision. Each truss is constructed from approximately 500 kilograms of concrete, metal reinforcement, and other coloring bases according to the recipe of the project’s conservator.The construction of these parts requires great precision due to the difference of each truss with its neighbors, which is of the order of one millimeter.
