FOUNDATIONS; EXCAVATIONS; EMBANKMENTS (specially adapted for hydraulic engineering E02B); UNDERGROUND OR UNDERWATER STRUCTURES

Introduced: September 1968

Description

E02D covers the technical design, construction, and engineering of foundations for buildings and structures, excavation methods and equipment, embankments and earth dams, and underground or underwater structures including tunnels and submerged installations. This subclass encompasses foundation types (piles, caissons, anchors), soil stabilization techniques, dewatering systems, and structural support methods for various construction projects. Adjacent subclass E02B addresses water management and hydraulic structures, while E02D focuses specifically on the ground interface and subsurface engineering aspects of civil works.
