The rapid Lean Construction-quality8 Rating model (LCR) is a unique and easy model to evaluate the quality and degree of leanness related to the pursuit of the leanphilosophy in a construction project. A standardized framework enables to combine qualitative evaluation through observation together with quantitative analysis. A categorized evaluation scheme is proposed within the same model, to easily visualize and interpret the rating results. The degree of LC-application is hereby distinguished between d-projects (low level, projects without any LC knowledge, low quality and highly wasteful) and aaa - projects (high level). This standardized rating model can be applied to all kinds of construction projects and within different geographic contexts. One hour of construction site visit and another half-hour for the analysis is required to undertake the rating. The model further suggests applying the rating model on three or more construction projects of one company. This should allow carrying the evaluation forward from a project to a company level.
