Maes Gwern

Sutcliffe undertook a detailed engineering appraisal for the Maes Gwern development, focusing on both civil and structural aspects to guide Wates Residential in accurately estimating construction costs. Our team assessed preliminary layouts, conducted topographical surveys, and reviewed desk study information to refine the development plan, aiming to minimise abnormal costs both above and below ground.

Project challenges

Key challenges included managing surface water and flood risk, which required a detailed appraisal to ensure the development met flood mitigation requirements while minimising its surface water impact. We provided a thorough tender design that addressed zero balance cut and fill requirements, abnormal surface water sewer systems, and plot-specific foundation needs.

Our engineering approach involved close coordination between geotechnical, civil, and structural teams to develop value engineering solutions that adhered to planning requirements. We supported the planning application by producing engineering details and participating in public consultations, where our engineers addressed technical queries and discussed surface water management strategies.

The successful integration of these elements demonstrated our capability to deliver complex engineering solutions while maintaining effective stakeholder communication and compliance with planning conditions.
