Rivenhall SDW1 is situated on a greenfield site, adjacent to an operational quarry and the main IWMF construction site, presenting unique operational challenges. The proximity to an active quarry required stringent safety and environmental controls to ensure that our activities did not disrupt the ongoing operations or compromise safety. The enabling works included constructing all essential platforms and site access points to provide a stable foundation for the IWMF EPC contractor. Key tasks were to stabilise local embankments, establish a 45,000m² working platform, and construct extensive below-ground service ducting and drainage infrastructure.
One of the most challenging aspects of the project was the requirement to steepen and retain a 670m long, 20m high slope, achieved using soil nails. Our team drilled 67,000m of soil nails to reinforce and secure the slope, ensuring long-term stability and safety.
In addition to the slope stabilisation, we constructed a permanent 2.2 km road network within the site, which connects with the 1.2 km access road. These roads are designed to accommodate heavy equipment and materials transportation throughout the IWMF project’s construction phases. The construction of a 35,000m³ lagoon was a critical component, designed to manage rainwater and site runoff effectively. This lagoon will support the ongoing site drainage needs, preventing waterlogging and ensuring safe working conditions.
Working adjacent to a live quarry and the IWMF main construction site required a precise logistical and safety plan to mitigate potential disruptions. By coordinating closely with the quarry’s operational team, we scheduled our deliveries and heavy equipment movements during off-peak hours to minimise impact. Additionally, our construction team employed advanced dust control and sound reduction techniques, which proved essential in managing environmental impacts in this active setting.
