In recent years, BIM information has received widespread attention from everyone, but the reason is that its prospects are optimistic and the future is worth looking forward to, so the information about it has value.

While paying attention to domestic information, we must also be curious about the situation of BIM in other countries and its impact on China. So let's talk about it in a simple and crude way today!

UK Government BIM Targets
In March 2013, the UK introduced the PAS1192-2 standard. This standard is part of the UK Government's construction strategy and is specifically aimed at strengthening project delivery management and financial management.

Its main purpose is to reduce the overall cost of public sector construction by nearly 20-30%.

In the definition of BIMTaskGroup in London, the second-level BIM refers to a series of domain-specific model combinations (such as buildings, structures, services, etc.), which can be used as a complete ecosystem for data storage and sharing. By 2016, all construction groups that expect to obtain government projects must prove that they have second-level BIM capabilities.

The 2015NBS( NationalBuilding Specification) survey report more clearly points out the British government's target for the construction industry, which is expected to be reached by 2025:
(1) 33% reduction in initial construction costs and maintenance costs during the life cycle;
(2) Reduce the construction period by 50% in the construction and renewal project;
Reduce greenhouse gas emissions by 50%;
(4) reduce 50% of the import and export of building materials trade barriers.

Development of BIM in the UK
NBS in the UK has conducted a national BIM survey since 2010. It has conducted an online BIM questionnaire survey on about 1000 construction industry employees in the fields of construction, engineering and surveying. It has entered its fifth year so far. The survey results clearly show that the British government has achieved remarkable results after about four years of efforts to promote BIM since the white paper on BIM was published in 2011.

Originally, only 13% of the people said they knew and were applying BIM in 2010. The survey in the last two years shows that it has reached about 50% steadily. In 2010, as many as 43% of the people said they had never heard of BIM, but in the survey in the last three years, only about 5% remained.

According to the survey on the application and prospect of BIM in the enterprises where they work, 50% have already applied BIM,83% said they will start applying BIM within one year, 92% said they will start applying BIM within three years, and 95% said they will start applying BIM within five years.

From the survey in the past two years, it can be seen that the number of people who think that their enterprises have BIM application maturity above Level2 has increased from 58% to 65%, with a growth rate of 12%, which is quite good. Moreover, the number of Level2BIM enterprises should also be enough for the British government to reach the goal of Level2 maturity in BIM application in public works in 2016.

In addition, the survey also shows that 77% of people agree that BIM will be the future of engineering information, but as many as 67% of people think that the industry's knowledge and understanding of BIM are still insufficient. On the one hand, it shows that BIM education still needs to be strengthened, on the other hand, it also shows that there is still a lot of plausible talk about BIM in the industry (30% of respondents said they don't trust what they hear about BIM).

Why BIM has slowed in 15 years: This year, NBS has completed its fifth annual survey.

Of the 900 respondents, 44% were architects. The survey tracked changes in respondents' attitudes towards BIM and their use of BIM. According to the survey data, only 48% of respondents said they were using BIM, down from 54% last year. The high cost and lack of expertise and training remain the biggest barriers to using BIM, and the survey also noted that about half of the respondents reported a lack of time to familiarize themselves with and learn about new projects. Almost two-thirds of respondents said that a shortage of customer demand was the main reason for not using BIM, and 43% of respondents said that their projects were too small to use BIM.

NBS responsible for research, analysis and forecasting AdrianMalleson said: there are still a large number of practical projects because they do not see the advantages of BIM, choose not to use BIM, while other projects because of time, cost or professional and technical issues, temporarily do not have the conditions to use BIM.

Advantages of BIM Development in the UK
Standard:
The Government's document calling for the mandatory use of BIM has been supported by the BIM Standards Council for the UK Construction Industry. At present, the standards committee is also developing similar BIM standards for ArchiACD and Vectorworks, as well as updated versions of existing standards.

These standards are developed to provide practical solutions and procedures for the transition from CAD to BIM for AEC enterprises in the UK, such as how to name models, how to name objects, modeling of individual components, data exchange with other applications or professionals, and so on. Product-specific standards are intended to explain and extend some of the concepts in the common standard in specific BIM product applications. These standards are written by members of the standards committee, who are drawn from the construction industry professionals who work with BIM on a daily basis, so these services are not only theoretical, but also applicable to the practical implementation of BIM.

Activities:
In addition to government policy support, many official organizations or non-governmental organizations also hold various BIM-related activities to promote the development of BIM in the UK. These activities can be divided into: large-scale technical seminars and exhibitions; small-scale technical seminars; government BIM standards and policy promotion; BIM basic concept promotion; BIM activities organized by private companies.

Company:
Design company advantages British design companies are already quite ahead in BIM implementation, as London is the headquarters of many of the world's leading design companies, such as FosterandPartners, ZahaHadidAr chitects, BDP and ArupSports, as well as the European headquarters of many leading design companies, such as HOK, SOM and Gensler.

Talent:
The British industry attaches great importance to BIM talents and usually gives software education and training when newcomers start working. However, BIM knowledge is not only software learning, so they hope that college students can have basic BIM knowledge and ability when they graduate.

Main Disadvantages of BIM Development in China
There is almost no construction project in our country that is not robbed of the construction period. What has been built in several years abroad can be completed in a few months in China, relying on the on-site adaptability.

Moreover, most of the projects in our country are completed in constant modification and compromise. This modification accompanies the whole project. This kind of strain rhythm cannot be kept up by BIM software in any case. If we expect to reflect the actual situation on site to the figure, the workload is too large.

The main reason for the popularity of BIM in foreign countries is that the BIM system is efficient, accurate and synergistic. Foreign designers have only modified a building for several years. Its project management standards and degree of synergy are high. Party A seldom makes changes day and night to avoid going back.

In addition, it cannot be denied that China's construction industry has been in a low-cost ecological environment for a long time, which makes enterprises do not have enough time and cost to carry out fine design, construction, operation and maintenance, which is an obstacle to the development of the whole industry and BIM.
