Abstract

The preconstruction field has struggled to adopt model-based practices and often lags behind in implementing similar BIM-based workflows in the construction industry. Model-based estimating practices provide a mechanism to increase efficiency and improve the overall preconstruction process. However, even as rapid growth in technology continues, current barriers to adoption persist, and the industry is challenged to educate and train the workforce to use these technologies effectively. A simplified model-based estimating framework must be identified and standardized to solve these barriers to adoption. This paper proposes a framework supporting a software-agnostic, standardized BIM-based workflow for preconstruction called the Integrated Estimating workflow, which relies upon five categories: 1) Intentional Model Authoring, 2) Qualitative and Quantitative Data, 3) Integration of Cost, 4) An Estimating Standard, and 5) Application of Automation or Augmentation to either parts of or the whole process. The significance of this framework is to identify an uncomplicated, but standardized model-based estimating workflow, and to create an identifiable distinction between this workflow and others commonly referred to as model-based estimating workflows.
