Project Overview

Upgrading the flood defence assets at Hilden and Lambeg weirs was a complex public infrastructure scheme requiring delicate underwater works and stringent environmental monitoring. SHEANEY was appointed to manage the project from the ground up, ensuring absolute compliance and smooth delivery.

Our Delivery

We delivered comprehensive project management consultancy directly, with no subcontracting of our oversight duties. Our team managed the full scope of health and safety advisory, risk management, and environmental compliance, ensuring the works respected the surrounding Scheduled Monument zones.

Key Achievements

Enforced strict compliance monitoring across sensitive waterways and heritage zones.
Maintained full Capital Works Management Framework (CWMF) compliance and delivered consistent, transparent monthly progress reporting.
