Project teams whose projects include Gunite and Gunite Mesh are not to include these materials in the MAT-05 and MAT-06 calculations as the the GBCSA confirm this is not considered structural concrete for the purposes of this credit. Gunite Mesh is generally made from >60% recycled content, however should Gunite Mesh be included in the project, the project team is to confirm the mesh is > 60% recycled content to ensure its exclusion in the calculations.
