The harbor was built using a combination of engineering techniques, including excavation, dredging, and the construction of breakwaters to protect against waves. Materials such as concrete, steel, and stone were employed to create docks and piers. The project typically involved extensive planning and design to accommodate water levels, tides, and shipping needs. Labor and machinery were also essential for transporting materials and shaping the harbor's infrastructure.
