NAMELY, to provide updated Environmental Noise Survey and HVAC Plant Noise Impact Analysis' report document with version 4.0 (dated 3rd August 2026). The changes to the report reflect the assessment based on a different window within the lightwell, which the neighbour identified as being a bedroom (previously assumed to be a bathroom). This has resulted in a change to insertion loss requirements for the plant enclosure.
