BIM-based cost management of large engineering projects

Abstract

The development of computer technology promotes reform of information technology. Building information model (BUM) is thus applied in cost management of large engineering projects. Thus, some shortcomings of traditional project cost management are solved and improved. One of important topics of " the 12 th Five-year plan " science and technology support programs is to research, develop and generalize BIM. BIM leads building industry to enter a higher level. This paper discusses BIM-based cost management of large engineering projects. Overview of BIM BIM refers to the model established on the basis of data information in the engineering project. It has important applications in design cost in the early stage of the project and building management in the later period. It belongs to a digital measurement method. BIM is a new computer-aided technology and can implement four-dimensional or five-dimensional simulated construction. It brings convenience for managers to predict, analyze and solve various problems in the initial design stage. The five-dimensional information forms through adding time and cost in BIM thee-dimensional model and reaches the purpose of direct project cost management. BIM can vividly confirm the material mobilization time and resource consumption within schedule scope, reduce storage cost and unnecessary material loss to the largest extent, and carry out dynamic project cost management. So, BIM technology has an important position in cost management of large engineering projects. Importance of cost management and control of large engineering projects
