Abstract—The term of value is the critical key for lean thinking, which is generated through a fulfillment of customer demands. Tackling the complexity between the project execution and value generation, using the classical way of management is a kind of challenge. Therefore, the optimization of the Value-adding generation is the core focus by this research, in which, a new understanding framework for rebuilding the conventional structure of Value-adding system into a new Value-adding Generation and Assessment model (VGA) is evolved. The mechanism of this model is to cause the value to flow across construction process in the best achievable sequence and rate through different conversations. These conversation are value design, mapping, analysis, adjust mapping, and processing and assessment, which are interchangeably accomplished. In addition, the VGA model framework is be characterized in terms of the principles that guide thinking and action, the functions, and the methods used to apply these principles and perform these functions. The development of the VGA model suggests a push towards a new understanding of the value-adding generation assessment process in construction projects. It further contributes to an efficient implementation of lean construction vision of completing projects with minimum Non-Value-adding activities ‘waste’ and maximum value.
