E02B HYDRAULIC ENGINEERING (ship-lifting E02C; dredging E02F)
Introduced: September 1968
Description
E02B covers the design, construction, and maintenance of hydraulic structures and water management systems. This includes dams, locks, weirs, sluices, breakwaters, seawalls, and coastal defense installations, as well as dredging equipment and sediment control systems. The subclass addresses both civil engineering works for water control and flood prevention, and structures for navigation and harbor development. Related structural foundations and earthworks are classified separately under E02D.
