Study and Realization of Core Calculation and Interactive Mode of Construction Project’s Cost and Schedule Dynamic Control System

Abstract

BIM (Building Information Modeling) technology has brought a global construction industry revolution. But in our country, we still fall behind with foreign countries in BIM software innovation, lacking of independent software platform and the core technology. In order to realize building software independent innovation, we must explore the core technology of BIM software. This study tries to find out the possible way for BIM software to calculate and interact, and tries to use GUI to compile BIM application framework, employing Matlab as a powerful tool for computing. The central idea of this program is to demonstrate the relation between the images and real-time data with controlled primary data and timeline. These images and data are extracted from a certain building, showing the stage and rate of the construction. The program mainly consists of the control part, the cost function and the graphic function. The control part is a slider representing timeline, allowing users to control time as a variable and view the full construction cycle when dragged from one end to the other. The cost function generates different kinds of value, which are needed to be observed and compared in the process of construction management, from time variable controlled by the slider, with expected cost, critical point of material usage and consumption rate as type-ahead parameters. The graphic function generates real-time construction image from time variable, with parameters such as expected critical point of construction schedule and the construction sequence of building structure. These graphics visually express building information changes. The program has constructed a core operation of BIM software which has broad prospects for development. By adding functions such as automatic material price search, process flow diagram drawing, flow construction plan generating, this software can be applied in all fields of construction. Using more advanced programming language, it can be perfected to a high level, practical and durable BIM software with native core technology.
