Today, the author will explore the application and development of BIM in the United States and the United Kingdom. This overview aims to highlight the influence of these developed countries on BIM, while also acknowledging the challenges faced in China’s BIM development. Our goal is to enhance the level of BIM application in China by learning from these experiences.
In the United States, the Office of the Chief Architect (OCA) of the Public Building Service (PBS), under the General Services Administration (GSA), launched a nationwide 3D-4D-BIM program in 2003. This initiative guided over 35 architectural projects in adopting 3D, 4D, or BIM technologies. The results demonstrated significant benefits in visualization, collaboration, simulation, and optimization, effectively meeting the needs of clients, designers, contractors, and project planning teams. Based on these successes, the GSA decided to gradually and comprehensively implement these technologies.
Starting in the 2007 fiscal year, the GSA mandated that all federally funded building projects submit their spatial BIM plans to the OCA for review by the PBS committee and chief architect. The GSA also actively encouraged the adoption of mature 3D, 4D, and BIM technologies across all projects, supported by the establishment of knowledge communities and the publication of BIM manuals. These efforts aimed to systematically promote BIM adoption within the public sector. Beyond the federal level, states such as Wisconsin and Texas have also mandated BIM use for public construction projects.
Following the U.S. government’s BIM mandate, the UK government took a similar approach. In May 2011, it announced that projects with budgets exceeding £5 million must use BIM. By June, the government introduced its “BIM Strategy,” requiring all construction projects to implement integrated 3D BIM models by 2016. The Royal Institute of British Architects (RIBA) also supported BIM through numerous research reports promoting its adoption.
A survey published in February 2012 involving 1,000 UK construction professionals revealed rapid BIM uptake: 31% had used BIM in at least one project, up from 13% in 2011. To further support the industry, the National Building Specification (NBS), managed by RIBA, launched the National BIM Library in the cloud in March 2012. This library helps the construction sector create standardized BIM objects for their products, supporting the entire supply chain.
The BIM object library, also called the Building Object Model Library (BOM Library), provides pre-built 3D models of construction products. Designers can select these objects directly, saving time on repetitive modeling and promoting information standardization. Using objects as primary units of information exchange helps establish a comprehensive supply chain, which is crucial for improving BIM efficiency. Notably, the new chairman of the UK Association of Consultants warned that companies failing to adopt BIM technology within five years risk being phased out.
By examining BIM development in the U.S. and UK, a common pattern emerges: both countries prioritize standards and government leadership in BIM adoption. In contrast, China is currently facing challenges due to a lag in standard setting amid rapidly evolving technology, which restricts BIM’s growth. However, leading Chinese cities such as Beijing, Shanghai, Guangzhou, and Shenzhen are developing BIM standards tailored to their urban characteristics. These efforts provide valuable references for other cities and help drive nationwide BIM development.
