Project complexities, simplified by Alpha:
- Undertaking works under Environment Agency Flood Risk Activity Permits, requiring detailed method approvals and compliance with strict environmental and regulatory controls.
- Maintaining flow, water quality and environmental protection during construction, implementing silt control, pollution prevention and monitoring systems to eliminate environmental risk.
- Constructing permanent sheet piled retaining structures within a live watercourse, requiring precision installation and coordination to ensure long-term stability.
- Operating within a live industrial environment with high HGV traffic, requiring careful traffic management, sequencing and safety controls.
- Coordinating multiple stakeholder approvals, including Environment Agency, Network Rail and local authority requirements, ensuring programme certainty and compliance.
Scope of Works:
- Installation of 210m of steel sheet piling (9m lengths) with reinforced capping beam, forming a permanent retaining structure to stabilise the watercourse.
- Excavation and widening of the watercourse, improving hydraulic capacity and reducing flood risk.
- Construction of a balancing pond, enhancing flood attenuation and managing peak flows.
- Riverbank reprofiling and stabilisation, using rip-rap stone and erosion control matting to prevent scour and long-term degradation.
- Installation of new drainage systems, including ACO channels and connections to existing infrastructure.
- Reconstruction of the adjacent internal roadway, including planing, resurfacing and reinstatement works.
- Implementation of silt and pollution control measures, ensuring protection of water quality during construction.
