This report provides commentary on the cost implications of a range of proposed Deemed-to-Satisfy provisions emanating from the Emergency Egress for all Occupants Project. This report was prepared for the ABCB by Rider Levett Bucknall (RLB) in order to prepare a cost analysis reflecting the capital cost implications of five proposals on a representative range of generic building scenarios. RLB accepts neither responsibility nor liability to any other party who might use or rely upon this report without our prior knowledge and written consent.
