Lean Construction 5.0: A Framework for Collaborative Decision-Making Powered by Artificial Intelligence and Intelligent Parametric Modeling

Abstract

Jorge Pablo Aguilar-Zavaleta and Maria Laura Lopez-Luna

The construction industry is going through a historic transformation driven by the need to overcome a chronic stagnation in labor productivity, which has averaged only 1% annual growth in recent decades. This article proposes a conceptual framework called Lean Construction 5.0, which transcends the digitalization of Construction 4.0 to integrate a human- centric, resilient and sustainable vision. The synergy between third-generation BIM, Artificial Intelligence (AI) and parametric modeling allows data capture and predictive analysis to be automated, optimizing decision-making in environments of high uncertainty. Through a review of recent scientific evidence, 30% reductions in design times and an improvement in weekly planning (PPC) reliability are documented from 50% levels to a range of 70-90% through the use of smart tools. The proposed framework emphasizes that technology should serve as an enabler of Lean principles (specifying value, constant flow, and perfection), operating under collaborative contracting models such as Integrated Project Delivery (IPD). The results indicate that the strategic integration of these components not only increases profitability by 13-21%, but also reduces environmental impact through the optimization of resources and energy. It is concluded that the transition to Lean 5.0 is inevitable to guarantee the competitiveness and sustainability of the sector in the 2025-2035 horizon.
