HYDRAULIC ENGINEERING; FOUNDATIONS; SOIL SHIFTING

Description

Class E02 encompasses structures and engineering works related to water management, ground stabilization, and earth movement. It covers hydraulic infrastructure such as dams, locks, canals, and flood control systems, as well as foundation design and soil mechanics for construction projects. The class also includes techniques for excavation, dredging, soil compaction, and ground improvement methods. Adjacent classes address specialized building construction (E04) and general civil engineering works beyond the hydraulic and soil-related scope of E02.
