Conceptual Framework for a Lean Construction Capability Model

Abstract

The Lean Construction capability model can be a beneficial tool for owners to assess contractors’ competence concerning the Lean construction process. The benefit of Lean is to focus on the true needs of the customer and prevent any waste from occurring during production. There is very little information available for creating a framework for a Lean Construction capability model that will assist the owners in assessing contractors’ Lean capability. This paper has examined the use of capability models in various industries and reviewed their methodological approaches and applications. Based on the commonality of the existing capability models, a conceptual framework for a Lean Construction capability model was developed. Key informants in Lean Construction were interviewed and their feedback was incorporated in the development of the framework. Subsequently, the conceptual framework was reviewed by owners. Overall, this study found that it is possible to create a framework for a capability model in the construction industry using lessons learned from other industries while valuing the foundational philosophies of Lean Construction. The framework used for Lean Construction needs to be flexible to fit the needs of a variety of contractors.
