Emerging Opportunities for Integrating the Digital Product Passport into Lean Construction Workflows: A Conceptual Perspective

Abstract: Digital Product Passports (DPPs) are emerging as mandatory, standardised sources of product information under EU policy. Yet their implications for construction-phase Lean workflows remain underexplored. Current practices still suffer from late discovery of product-related constraints, missing documentation, and weak traceability, undermining task readiness and plan reliability. This study combines a scoping search with conceptual mapping of DPP data categories to digital Last Planner System (LPS) decision points. Results include a DPP-to-LPS integration framework and construction-oriented guidelines for make-ready, commitments, and receiving/QA. The contribution is a practical research agenda for operationalising DPPs in Lean execution and enabling data continuity (e.g., DBLs-related).
