In recent years, the BIM technology is under promotion in domestic construction industry of China, with many construction enterprises and architectural design enterprises formulated their own enterprise-level BIM technology development plans. All these plans will inevitably involve BIM demonstration projects. The authors of this paper has participated in the management of five batches of BIM demonstration projects in CSCEC in the past five years. In this paper, experiences are summed up concerning all the processes of BIM demonstration projects in construction enterprises including top-level planning, project declaration, process control, and acceptance and promotion. This paper also answers some questions like how should the management department of BIM demonstration projects guide BIM demonstration projects to apply BIM technology, as well as how to improve BIM application by promoting these demonstration projects. All these experiences can provide references for related enterprises that are carrying out BIM demonstration project management.

This paper will introduce the description and implementation methods of Industry Foundation Classes (IFC) by instances for your further study, development and application.

This paper will introduce the shape representation and spatial structure of Industry Foundation Classes (IFC) by instances for your further study, development and application.

As collaborative design has come into construction industry, the application of BIM (Building Information Modeling) has updated the information in modeling software dramatically. IFC, an international standard, is a choice of modeling data exchanges. With IFC standards, this paper will make an analysis of these exchanges particularly.

It has experienced decades that BIM (Building Information Modeling, referred to as BIM) is from a proposal to gradually improve, to the general acceptance of the construction industry. With the popularity of BIM applications in foreign countries, the application of the domestic construction industry is in full swing. The urgent need for standardization of BIM to construction of the related industrial chain link sharing and application of BIM. This paper introduces the design business owners, industry associations, research institutions and engineering companies BIM standard system state of progress of the construction industry for the domestic counterparts in the standardization of information and BIM to provide a reference.

An important upgraded version for IFC standard will be soon published, and the structural analysis model was mature. It will be the key support for future building data exchange. This paper focused on the structure analysis model and architecture model of integrated application technology, fellow the development of IFC standard, analyzed optimal method and described some specific data cases.

The notion of project information management system (PIMS) has existed for decades.But by now, those who work in the area can not draw a consensus and common understanding of PIMS, and there are no industrially stable PIMS in existence.This paper aims to analyze the cause, and presents the authors'view.Authors proffer an open framework of PIMS as a reference for software development in the area.

Construction industrialization is the very trend in the building industry of China.The deeply integration of informatization and industrialization is the inevitable course of transformation and upgrading of the construction industry.Based on this, from the perspective of supply chain optimization management, we integrated all the project members into a unified platform.On this unified platform, the core elements of key link work collaboratively is established on the basis of the BIMmodel.This platform is a digital lean construction platform to integrate virtual construction technology, internet of things technology, cloud services technology, remote monitoring technology and high-end aided engineering equipment.On the platform, the whole construction project is under the control of the supply chain management and achieve optimal project of business process, shortest cycle, lowest cost, minimum inventory, faster cash flow, enterprise value maximization.Based on the actual case, the achievements of the prefabricated digital lean build platform based on supply chain were showed, and the developments of the platform for the future were discussed.
