The Playbook recognises the need for procurement to improve building safety in the wake of the 2017 Grenfell Tower fire tragedy, and underlines that 'setting the right behaviours and practices throughout the design, construction, occupation and maintenance stages, and the handoffs between these stages, is crucial to ensuring building safety' (p.4). Frameworks have a central role to play in improving building safety because they can establish and incentivise consistent and measurable safety practices that span multiple projects, multiple clients and multiple suppliers. For example, they enable the early creation and validation by housing clients and suppliers of the safety information required to support the progress of each project through the Building Safety Regulator's gateway reviews.
