This paper is a presentation on the three tech trends shifting the BIM industry recently, which are the Internet of Things(IoT), Cloud Data Management and augmented reality(AR), respectively.The author introduces the development of the combination of those three tech trends and BIM technology, as well as new solutions the combination produces to issues in practical engineering.Accordingly, conclusions can be made that these technology trends will help the AEC industry to get the most out of BIM.

Nowadays, equipped with the more advanced BIM technologies, the whole construction industry should be more purposefulness in project management, adopting a reasonable technological path to achieve the clearly defined technical goals. Aiming at the informatized management on green construction in projects, and from the perspective of project management, this paper develops a BIM-based informatized green construction management platform integrating the new technologies of BIM, IoT, and etc., to meet the needs of green construction evaluation. The paper sorts out the overall functional framework of the platform and the specific functional modules. Through the application of the platform, a project is able to implement detailed and targeted green construction management according to the initial objectives of green construction established by the project, and to evaluate the achievements of green construction management, which will surely improve the overall level of green construction management.

The paper lists serious typical problems existed in the design of house decoration, including inapplicable service model, dis-uniformed design platform and non-centralized design resources, and puts forward an integrated cloud-based service and application solution of house decoration as well.Based on the cloud-platform architecture, unified authority and collaborative design tools are adopted to achieve the centralized management of enterprise design resources.The implementation of cloud platform and its application popularization have proven that the cloud platform is able to promote the innovation of Internet house design pattern effectively, to bring new experience for house decoration design services, and to improve the efficiency of enterprise resource supply chain configuration significantly.

Home improvement design industry is an important piece in domestic construction field in China.Through the research work of this paper, we have established a BIM-based home improvement design software for the home decoration design industry.The paper briefly introduces the main functions of the software system, and then describes in details the algorithm design ideas of several main functions.Some screenshots of thesoftware operation interface are also shown in the paper to illustrate the function and effect of function realization in software implementation.The innovative application of the software will provide both the home improvement designers and the customers with brand new experience in home improvement, and promote the development of new pattern on the home decoration industry.
