The Property Management Industry Has a Memory Problem

UK residential block management has a memory problem. Knowledge about a building, such as why systems were specified, why works were deferred, what was tried before and what it cost, accumulates in the heads of property managers, in inboxes and in disconnected systems, and is routinely lost when people or managing agents change. Drawing on knowledge-management theory, research on construction-to-operations handover and on multi-owned housing, and five building handovers observed by the author, this paper argues that failures of organisational memory contribute to persistent problems in leasehold management. It proposes a Building Knowledge Hierarchy (data, information, knowledge, organisational memory and building intelligence) and a Persistent Building Knowledge Model, in which knowledge attaches to the building and its assets rather than to the individual, document or system through which it arrives, and in which provenance, confidence and the reasoning behind decisions are preserved. It positions the model alongside the statutory Golden Thread for higher-risk buildings, arguing that its principles should extend to a building’s wider operational and financial history. It builds on asset-information approaches such as ISO 19650, digital twins and building logbooks, while addressing the difficulty of maintaining usable knowledge across fragmented ownership, incomplete records and changes of managing agent. Its contribution is to bring established knowledge-management principles together around that transition. It considers how artificial intelligence changes the economics of maintaining such memory, the risks this introduces and the data-protection boundaries it must respect. It concludes by describing BlockGenie, a managing agent being built around the model, and the baseline against which it will be evaluated. The central proposition is organisational rather than technological: knowledge should belong to the building.
