ByrneLooby prepared all planning documentation and successfully submitted the planning to Cork County Council Planning was granted within 8 weeks, further a request for further information. Subsequently, ByrneLooby carried out the geotechnical and structural design for the flood defenses. This included design and specification of reinforced concrete chambers, flood defence embankments, design of an integrated attenuation pond and underground tank system with an automated flow controlled outlet arrangement.
