Application of Artificial Intelligence Technology in Smart Building Integrated Management Platform under Big Data Environment

The rapid development of the construction industry has led to a wider application of artificial intelligence technology, and the application of this technology to the comprehensive management of intelligent buildings can promote the construction of intelligent construction sites and improve the level of quality management. In this paper, on the basis of elaborating on the intelligent building design, the framework of the intelligent building comprehensive management platform is built by combining 5D-BIM technology and artificial intelligence technology, and engineering cost modeling is carried out based on the whole process control of engineering cost. The engineering cost prediction model is established based on the BP neural network, and a genetic algorithm is introduced to optimize the initial threshold of the model so as to obtain more accurate prediction results. To verify the effectiveness of the intelligent building integrated management platform application, data analysis is carried out across three dimensions: engineering cost control, prediction, and application. The whole process of cost control makes the peak value of cost-effectiveness reach 4.25*108 yuan, the average value of project cost reduction reaches 78.68%, and the relative error of project cost prediction results minimizes to only 1.77%. The process of processing project information was shortened and improved by 9.15% and 8.06%, respectively, and the backlog reduction rate of project materials could be reached by 24.76%. The intelligent building integrated management platform that utilizes artificial intelligence technology promotes construction project intelligence and effectively reduces construction costs.
