Abstract

In order to develop an algorithm for selecting the most optimal organizational and technical solutions during design process, and the following automatization of this process, the problem of using 4D modeling programs in the organization and technology of construction is considered. A 4D -model cannot exist without detailed 3D-model and allows taking into account different variable factors in real time. In addition, software that uses 4D-modeling makes it possible to reduce significantly the time needed to prepare a project, to take into account flaws and mistakes at the different design stages. The concept of the 4D model connects in real time the elements of the model with the elements of the plan, which are recorded by means of programming. Algorithm proposed by us includes a control-system, when each subsequent stage implies the complete completion of the previous one. Unlike traditional design technology, when the object options may differ in the scope of work, preliminary cost, etc., the use of a simplified 4D model allows pre-determining the best option. Also, BIM technology minimizes time costs by allowing designers and geodesic surveyors to work together. The information collected in the 4D model is saved by the operation company and is used during the operation of the object. The 4D programming allows us to optimize production processes, to visualize the construction of objects, and to solve the problems of the economic efficiency of the real estate objects construction with a high degree of probability.
