Abstract

Planning in multi-storey buildings is often constrained by manual processes and tacit knowledge, which hinders the systematic application of Lean principles. This paper presents the formalisation of a structured method based on three deterministic spatio-temporal rules—stable rhythm, vertical continuity, and non-crossing—and its instantiation in a computational artefact developed in Excel/VBA under the Design Science Research approach. The automation reduced the processing effort of an otherwise exhaustive manual procedure to a few seconds, allowing the agile exploration of multiple rhythm scenarios. Its application to a real residential project provided a real-data environment for the artefact instantiation, supporting the identification of a schedule recovery potential of 21%, assessed significantly faster and more consistently than through conventional planning approaches. The results demonstrate that the integration between the method and its technological instantiation enhances data-driven decision-making, strengthens operational predictability, and supports the transition towards a more flow-oriented planning system.

Keywords
