Using BIM 5D For The Dynamic Management Of The Cash Flow In Milestone Payment

Cash flow management is to achieve the goal of maximizing the value of a comprehensive system of management activities, through planning, forecasting, analysis, decision-making, control and other means, the time and quantity of cash flow, cash flow. The lack of effective management of cash flow is more likely to lead to the failure of the project than for the other contractors. Effective cash flow management is usually refers to the project cash inflow and outflow of cash for effective forecasting, implementation, monitoring and feedback control.At the same time, the dynamic management of the cash flow of the project is very important for the contractor. Because in the engineering project, the project’s cash flow situation is the dynamic is along with the development of the project and the gradual change, and is not invariable process, is the construction process, many outside factors will have the influence to the project project’s cash flow condition. The Contractor’s cash flow management of the engineering projects is not possible, and may cause the Contractor’s own capital utilization efficiency is not high, resulting in a decrease in the profit rate of the project. Therefore, in the process of the analysis of the cash flow of the project, it is sure to make a dynamic management of the cash flow of the project.Contract pricing model, which provides a method for the payment and risk allocation of the contract, coordinates the target of both parties. Milestone payment conditions are often adopted in the engineering contract a payment, in the milestone payment conditions, project faces many risk factors, uncertainty is strong, with obvious risk probability and loss of double height characteristics. Therefore, the study of milestone payment project cash flow dynamic management for contractors is particularly important.Although China’s construction industry has begun to use BIM technology, but the construction industry in the use of BIM technology is far from enough, just limited to design, simulation and other common functions of the collision, and the BIM data is not integrated into the advantages of the full play out. Especially in the cash flow management of engineering projects, the implementation of the relevant implementation of the BIM related cases and the implementation of standards.In recent years, the concept of BIM 5D building information model is frequently mentioned in the industry. BIM 5D is based on the BIM 3D to add the cost (cost) and time (time) of the two dimensions of information, so that the building information model not only contains a three-dimensional model, but also contains the progress of the project and cost information. BIM 5D further makes the modeling ability and application scope of BIM technology to be further enhanced.From the dynamic management of project cash flow, especially in the cash flow management, BIM 5D technology can integrate the information of planning and design phase, construction stage and operation maintenance phase, and the information of the whole project is integrated into an organic whole, and BIM 5D technology is based on data processing. The core technology of BIM 5D technology.
