In order to prove the ability of BIM Technology Application, obtain social and industrial recognition, transfer trust to customers and standardize their application and services, it is necessary to have unified standards to evaluate the completed processes and results in the planning, design, construction, operation and maintenance stages of the project, and review the business collaboration, quality, BIM information management and other processes in each process, Implement verification, which can better promote BIM Technology Cooperation and serve all stages of the whole life cycle of the engineering project.
1、 Background
Building information modeling (BIM) is to establish a three-dimensional building model based on the relevant information data of construction engineering, and simulate the real information of the building through digital information simulation. It has the characteristics of information relevance, visualization, coordination, optimization and simulation. In recent years, BIM has been promoted and developed rapidly in the global construction industry.
As early as 2011, China incorporated BIM application into the 12th Five Year Plan to build BIM Technology and standards and software development innovation platform. In 2014, the Ministry of housing and urban rural development and the General Administration of quality supervision, inspection and Quarantine jointly issued the BIM design information model delivery model standard and the unified standard for the application of construction engineering information model. In July 2015, the guidance on promoting the application of building information model (JZH [2015] No. 159) issued by the Ministry of housing and urban rural development proposed that the objectives of BIM application include that by the end of 2020, class a survey and design units in the construction industry and special and first-class housing construction enterprises should master and realize the integrated application of BIM with enterprise management system and other information technologies. In the survey, design, construction, operation and maintenance of newly approved projects, the project rate of integrated application of BIM reaches 90%.
Since the beginning of 2018, the certification center of China Construction Association has been committed to studying the high-quality development requirements in the field of BIM Technology Based on many years of architectural specialization research results. Under the guidance of the Ministry of housing and urban rural development and through full cooperation with relevant international organizations, up to now, more than 40 enterprises have been issued with corresponding level certification or evaluation certificates, covering design institutes, engineering projects, enterprise BIM centers, relevant software and hardware suppliers and other fields. From May 16 to 17 this year, the certification center of China Construction Association and China BIM certification alliance jointly hosted the first BIM service certification and software and hardware evaluation technology training course, and trained a number of experts for standardization management in BIM field through the deep integration of BIM Technology Application Theory and practice.

2、 Development and application of standards
In order to prove the application ability of the enterprise, the enterprise BIM Technology Center and the project at all stages to satisfy customers, so as to obtain wider recognition of the society and the industry, it is necessary to introduce an authoritative third-party organization for evaluation to verify the enterprise, the BIM Technology competent department and the completed projects, Through evaluation and exploration, we can find the level of BIM Technology Application in the industry, tap the potential of BIM Technology Application, and better promote BIM Technology to cooperate and serve all stages of the whole life cycle of engineering projects. For a period of time, all enterprises, BIM Technology centers and projects have great willingness to find out and evaluate their own ability level, but the current situation is that to implement the comprehensive evaluation of BIM technical service ability, the unified and effective core standard of evaluation is missing.
After nearly two years of cooperative research, China Construction Association Certification Center and China BIM certification alliance have initially formed a series of achievements. Developed and released the technical guidelines for the evaluation of BIM certification demonstration projects of engineering projects V2 (certification basis standard), information technology environment building model (BIM) certification: demonstration computer hardware, information technology environment building model (BIM) certification: demonstration computer software and other standards.

In order to guide the evaluation of BIM certification demonstration projects under China's BIM certification system, China BIM certification alliance and China Construction Association Certification Center organize the development and preparation of BIM application evaluation guidelines for the design and construction process of civil buildings, industrial buildings, infrastructure and other engineering projects. As the experts of China BIM certification Alliance said: China BIM certification aims to provide the industry with personnel with relevant ability levels and the selection of excellent software and hardware environment, ensure that the service party procurement can obtain qualified BIM results, and ensure the collaborative delivery of the whole life cycle of engineering information. For the research on the certification system, a special technical committee was established in 2018, which is composed of well-known experts and scholars from all over the country and the engineering construction industry to jointly formulate the technical route for BIM certification research. In June 2018, China Construction Association Certification Center Co., Ltd. evaluated 12 demonstration projects and 4 sets of demonstration software and hardware tools according to the certification procedures and standards. The certificate was issued at the "China BIM certification system press conference" on July 3, 2018.

3、 Implementation of BIM certification
Project BIM certification takes a single engineering project as the evaluation object, and carries out overall comprehensive evaluation based on the buildings, structures, facilities and equipment of a single engineering project. The BIM certification of the project is divided into design BIM certification and construction BIM certification, and shall comply with the following provisions: the design process includes scheme design, preliminary design, construction drawing design and detailed design; The construction and installation process includes construction organization, bidding and procurement, technical management, process management, product management, etc.
The standard guidelines have detailed evaluation provisions on model organization, geometric information and attribute information, deliverables, collaborative process and application quality. According to the different characteristics of design and construction stages, evaluation scoring checklist and other tools are developed and set up.
The implementation of BIM technical service certification is inseparable from the development and evaluation of reviewers' ability. In order to better serve enterprises and projects, bimw service certification and software and hardware training jointly sponsored by China Construction Association Certification Center and China BIM certification alliance will train and organize discussion on Certification Implementation personnel from the technical ability and review implementation ability, mainly including the understanding of certification standard terms, the use of evaluation form, and the application technology of Bim in design and construction projects, And software and hardware development and testing technology. At the same time, pay attention to and understand the actual application status and needs of enterprises for BIM, provide an exchange platform for enterprise BIM application technology managers, and formulate BIM certification scheme.
