ABSTRACT
The Paragon Park phase 3 project consisted of constructing a 9.5m high noise bund, 400m in length between a new housing development and a metal recycling facility located in Coventry, Stoney Stanton Road which is in a densely populated area. One challenging aspect of the project was the soil conditions and the fill material, where site won material was to be considered to reduce the overall cost therefore avoiding the use of imported material which would also reduce the disturbance to the local community and travelers during the day. The face of the bund was also a challenge as the client wanted an aesthetic face therefore, we had to consider what possible solutions could be installed on the 70-degree steep face. The bund was built on top of a well prepared and compacted started layer and the site won material was used for the build-up of the bund with multiple layers of geogrid at various length to reduce the material cost. Within the face a rivel mesh system was used to keep the topsoil soil retained at the face with the use of the erosion control mat wraparound and help achieve the 70 degrees as each layer was constructed to achieve the total height of 9.5m. The key elements used to construct the bund: Geotextile Ekotex (nonwoven) used for separation between the different soil materials used for the project, Geogrid Strata to strengthen each layer of the bund, Erosion Control Landlok to achieve a vegetated face and a rivel mesh system to help achieve a 70deg face throughout each layer of buildup.The project was designed using the programs of Reslope and Ressa following the British Standards BS8006:2010 internal stability, Partial Factors and Interaction Factors.
