Reserch On The Application Of BIM Technology In Cost Management Of Real Estace Industry

For real estate industry,no matter vigorous development in the past two decades or adjustment and slowdown of industry today,the profit-maximizing pursuit is always one of the most fundamental purpose.However,facing on different requirements of customers and completely different social market environment with the past,the measures taken and management methods have also changed in order to achieve the established profit targets.Nowadays,people pay more attention to the improvement of building quality.In the face of new customer need,enterprises have to achieve corporate profit targets by means of effective cost management and control.Therefore,a reasonable cost control and effective cost management will be the most important contents for cost management in real estate projectBeing one of the three main objectives of project management,the cost control idea is different between the past and now.In the conventional ideas,the construction organization often achieves the goal of maximizing savings of cost by cutting down expenditure when ensuring the quality of the premise.However,nowadays the whole process of cost management is replacing the traditional way,because cost management exists throughout the whole phases.Then the problem is how to adapt to the change and carry out the whole process of cost management,which is an important issue for business and theoretical circles.As an emerging technology,BIM is considered to be the second revolution in construction project.It takes fully advantage of computer networking technology,and integrates the knowledge and information of every specialty,and is presented with a visual model.Although its emergence is late,it has been the rapid application.And a series of research results have been obtained.Based on the literatures and research results,and by RK City project,the paper analyzed on the cost management of the first and second stage project,such as investment estimates and program selection at decision-making phase,the quota design and collision inspection at design phase,the project measurement of quantities and price of calculation and calibration at bidding and tendering phase,the calculation and 3D design at implementation phase.Finally,the paper summed up the management utility,economic utility and comprehensive evaluation based on the comparative analysis,in which the comprehensive evaluation is to use principal component analysis and fuzzy comprehensive evaluation to analyze by the established evaluation index system.Through above research and analysis,the following conclusions are drawn:Firstly BIM technology has a positive impact on project cost management and improves mechanism of sharing information;Secondly,BIM technology has also improved the economic efficiency which is to save a lot of time and cost for the project.Thirdly,a set of evaluation index system is established which is suitable for evaluating the application of BIM technology in RK City project.And according to the results of the fuzzy comprehensive evaluation,it finds that the application of BIM technology is satisfied with efficiency,accuracy,relevance and convenience,as well as the overall evaluation.Fourthly,the results of principal component analysis show that the proportion of efficiency and accuracy is the largest.That is to say,the efficiency and accuracy is paid more attention in RK City project in the premise that other factors are very important.Finally,the paper put forwards some suggestions from the following aspects,such as organization management and software construction,supplier resource reserve and driving mode.
