Estimating The Dynamic Impact Of Building Project Cost Based On BIM

Many benefits of building information modeling(BIM)technology have been recognized and reported in the architectural,engineering and architectural(AEC)industry literature.However,the construction industry still seems to be hesitant to fully adopt BIM.As some researchers have said,the root cause may be a lack of understanding of whether and how BIM can improve project outcomes.The purpose of this study is to explore the impact of the application of building information modules on the performance of construction projects,with a view to enlightening this issue.This study uses a model-based approach rather than statistical analysis of project results,whether BIM is used or not.The supply chain of construction project is modeled at the level of design and construction activities to represent the cost behavior of the project over time.Because the traditional project management tools and statistical methods can not consider the dynamic characteristics of the project,such as feedback,time delay and nonlinear relationship,this study uses the system dynamics method to model the project supply chain.The project supply chain model is calibrated by two sets of projects: Bim and BIM free.Two calibration models,non Bim and BIM used,are used to estimate the results of a set of hypothetical items.The results are compared according to the project performance indicators,and the impact of BIM on project performance is analyzed.Due to the relatively small number of projects using BIM,this study uses expert heuristic(EE)technology to obtain the required knowledge from the industry to estimate the parameters of BIM using model.EE is used to build a causal model to capture the impact of BIM utilization on non BIM project model parameters in the absence of sufficient BIM project data.
