As the construction industry advances toward decarbonization, Life Cycle Assessment (LCA) is becoming an essential tool for evaluating and reducing embodied carbon. However, most BIM models used in practice are not structured to support reliable LCA, particularly at the permit and construction documentation stages. This session explores the gap between BIM and LCA workflows, referencing ISO 14040 and ISO 14025 frameworks, and highlights key limitations in current industry practices. Drawing on case studies, it introduces a practical quality-control approach to improve BIM model readiness by addressing issues such as missing elements, inconsistent material definitions, and data misalignment. Attendees will gain actionable insights to better align BIM models with LCA requirements and support more reliable embodied greenhouse gas assessments in professional practice. The session is one hour and includes a 15-minute Q&A.
