SOA Category OG8
SOA certification for river works, hydraulic defense, water management, and land reclamation
The OG8 category covers river‑engineering works, hydraulic defense systems, water‑management interventions, and land‑reclamation projects – fundamental activities for territorial protection and the prevention of hydrogeological risk. OG8‑qualified companies contribute directly to soil defense and community safety by carrying out works that prevent landslides, floods, and environmental damage, thus strengthening the resilience of the territory.
Works and interventions covered under OG8: embankments, canals and basins
OG8 applies to a broad range of civil and environmental engineering works, from river regulation to hydraulic defense of the territory. Key examples include:
- River embankments and flood‑protection works: construction or reinforcement of embankments and riverbanks, using rock revetments, gabions, or concrete walls to contain floods and prevent erosion.
- Canals and land‑reclamation works: construction of diversion channels, drainage canals, and reclamation works to divert floodwaters or drain marshland, including navigable or irrigation canals.
- Flood‑control basins and hydraulic storage: construction of expansion basins, flood‑retention areas, small dams, or movable weirs to regulate flows and reduce flood risk.
- Mountain‑stream stabilization: check dams, drop structures, energy‑dissipation basins, and slope‑stabilization works for torrents and unstable slopes.
- River mouths and transitional zones: hydraulic works at river mouths and lagoon areas, often integrated with OG7 coastal‑defense projects.
Related SOA categories that integrate with OG8
OG8 hydraulic projects often require multidisciplinary expertise and integrate with several general and specialist SOA categories:
- OG6 – Water and utility networks: OG6 covers aqueducts, gas pipelines, and sewer networks; OG8 covers open‑channel works such as canals, embankments, and hydraulic basins. In irrigation or reclamation projects, OG6 handles pressurized pipelines while OG8 handles open‑channel drainage or storage.
- OG7 – Maritime works: OG7 concerns ports and coastal defenses, while OG8 concerns rivers and inland reclamation. In transitional zones (estuaries, lagoons), both may apply.
- OG5 – Dams: OG5 covers major dams; OG8 covers smaller flood‑retention structures and expansion basins.
- OS21 – Special structural works: required when deep foundations, diaphragm walls, or large consolidations are needed; OG8 covers hydraulic works, OS21 covers the structural foundations.
- OG13 – Environmental and natural‑engineering works: OG8 focuses on hydraulic regulation; OG13 focuses on ecological stabilization and revegetation.
- Additional categories: OS1 (earthworks), OS23 (demolition), OS25 (archaeological excavations), OS28/OS30 (pumping or hydraulic systems).
