This report, General Inspection (Investigation) Report Eight (GIR8) details the findings of Building and Energy’s investigation into how building standards are applied from the approval process, through procurement, manufacturing and installation of barrier products.

As part of its investigation, Building and Energy interviewed industry members associated with barriers including all those involved from the design through the whole supply chain, to installation. This helped to build an understanding of existing practices within the barrier industry and the building approval process and to gain insight into the procurement process of barrier systems and the relationship between the following parties:-

• the builder and the barrier supplier/installer;
• the barrier supplier/installer and the structural engineer;
• the builder and the building surveyor; and
• the building surveyor and the barrier supplier/installer.
