Overview
Adey Steel was tasked with delivering a range of steel components for the construction of the Earls Pumping Station.
Scope
The supply scope involved manufacturing high-quality steel components for shoring and formwork in tunneling and excavation. Deliverables included a detailed Tekla manufacturing package with prep drawings, cutting lists, NC data, and fabrication/welding instructions.
Materials used were S355J2 plate and S355J0 section grades, suitable for structural applications. Manufacturing followed BS EN 1090 Execution Class 2 standards, ensuring precision fit-up, welding to qualified procedures, and rigorous non-destructive testing, including ultrasonic testing, magnetic particle inspection, and visual inspection to ensure defect-free components.
Final assembly and inspection involved fit-up verification and quality checks before dispatch. A total of 77 tonnes of steel was delivered with coordinated logistics. Quality assurance included 3.1 material certification, welder traceability, and NDT reports for compliance.
Adey Steel's waler beams and steel brackets were crucial to the Earls Pumping Station and Thames Tideway Tunnel. The waler beams supported vertical shoring systems, preventing soil collapse and ensuring worker safety during excavation. They also served as formwork, stabilizing tunnel walls as concrete set. The steel brackets reinforced the pumping station, distributing heavy loads and maintaining structural integrity throughout the project.
