Smart building develops slowly, accompanied by technology giants


” The idea of Internet manufacturers is to start from the connection of underlying data, which is also the reason why manufacturers build their own BIM capabilities

.

Building is basically the logic of buying hardware and things

.

In the future, with the requirements of the three red lines, more and more real estate development enterprises will go to the idea of high quality, which will be the overall trend

.

” 03 “under the ceiling”, the “linkage” of buildings, parks and cities mentioned by song bin is gradually reflected in smart parks, urban BIM, CIM base and other projects, which is also one of the most concerned fields of large factories at present

.

“The low degree of digitalization of the industry also shows that there is enough room for improvement, which is one of the reasons why Internet manufacturers have entered the market.” Liu Gang, a researcher (pseudonym) in the construction industry of a large securities firm, told taibo.com: “in terms of prefabricated buildings with the most BIM applications, the penetration rate of Bim in the newly started area is only less than 10%, less than 20%, and the data in 2019 is 13%

.

From the aspects of bidding, qualification, approval and standards, the government has launched a large number of new policies to promote Bim and construction industry internet

.

By 2025, the overall goal of each region is generally between 25% and 30%, and there will be a relatively fast room for improvement in the penetration rate within five years.” “Since 2013, we have been thinking about how to combine architecture with the Internet.” Wan Chao, vice president of Tencent cloud, revealed in an interview with taibo.com: “we have been doing it silently for five or six years, doing a lot of exploration and taking a lot of detours.” Wan Chao said: “in the 40 years of reform and opening up, the vast majority of building construction in China has taken the large-scale effect

.

The input in the first 1-2 years may be relatively large, but the output may continue to increase in the third and fourth years

.

In this process, we have ignored the cost reduction and efficiency increase, and we have not taken the road of science and technology building

.

At this time, digitization plays a role of overall efficiency, which changes the whole management mode rather than a certain link or process

.

Recently, a piece of news that “Zhang Lizhou, the former president of Huahong Jiaxin, joined Alibaba as the vice president of Alibaba group last year and was in charge of the intelligent building business unit” once again drew the public’s attention to the intelligent building business of big manufacturers

.

It is understood that the area where Wang Xi’s branch is located has required new residential buildings to provide BIM models including water, heating and electricity to small owners, which also poses new challenges to operators: “in the process of civil engineering and pipeline, lamps and other models integration, there will be some technical problems, which need to be run in.” More importantly, “BIM costs for new buildings are not large, because personnel need to serve the whole process of the project

.

“In the past, intelligent buildings are all based on the idea of informatization, which is to provide intelligent solutions for a single business, such as air conditioning control, visitor management, etc

.

At the same time, buildings are more closely related to parks and cities, and the trend of overall communication and linkage is very obvious

.

โ€Wan Chao revealed that Tencent’s wisdom building “essentially hopes that data can be connected”

.

In fact, it is a return to the digital foundation.” Wang Jia said: “it is necessary to integrate the static and dynamic data of the building to form a digital building

.

” Wang Jia, Professor of Beijing Jianzhu University and co-founder of Yingjia Internet, told taibo.com

.

In 2019, Ali won the bid of 40.22 million yuan for the BIM management platform of xiong’an New District, which is also known as “a thunder from the ground” by the industry, shaking the construction circle

.

most of them are isolated systems, data can’t be integrated, and they don’t have the ability of decision-making and analysis, so they can’t achieve real” wisdom

.

In the short term, it’s OK to design only a certain link of the industrial chain or a certain business line

.

In March 2020, Tencent released the cloud BIM collaboration platform of Tencent, and in April, it launched the bottom platform of smart city, citybase Tencent cloud, to launch a blueprint for building a city CIM base

.

On this basis, it is necessary to use data drive to solve the problem of application scenarios, realize automatic control and decision-making early warning, and make the building more and more intelligent

.

” “When we expand to the operation and maintenance period of buildings, we will find that whether it is public construction assets or the management of large property companies, the informatization work is also in full swing

.

From building informatization to intelligent building and then to intelligent building, the concept of informatization in the field of building has been put forward for more than ten years, and the building layout of Internet factories has also been for several years

.

But if we only rely on the power of developers, I think BIM will be difficult to completely push forward in 5-10 years

.

” Song bin is quite confident in the future of smart building: “from 2017 to 2018, the development of smart building has begun to accelerate, and now it is almost exponential growth

.

All hardware factories have their own” moat “and agreements, and all data in the building cannot be connected

.

In addition to Huawei’s CIM based smart Park, Xiaomi’s high-profile release of smart real estate solutions, iFLYTEK’s BIM + AI cooperation with the Chinese Academy of Building Sciences, the seemingly “sudden attack” of big manufacturers has completely disrupted the pool water in the construction field for many years

.

In this process, BIM data is an important source of static data, and promotion is imperative

.

After all, according to the McKinsey industry informatization index in 2018, the informatization degree of the construction industry is still in the last place

.

If the BIM design fee is increased, the original design fee of 50-60 yuan per square meter may be increased to 80-100 yuan per square meter.” Because of this, Liu Gang is conservative about the development speed of residential Digitization: “the overall technology in the construction field has been very mature, and the superposition of BIM will not have obvious effect on cost control

.

“When you look at the whole life cycle, medium and long-term value chain, the data model of Digital input-output is different

.

In terms of enterprises, various architectural engineering design institutes and large enterprises in the construction field are also trying to promote BIM

.

” Wang Xi (pseudonym), an employee of a construction enterprise, disclosed to taibo.com

.

02 input output ratio, a difficult account “BIM” has been shouting for several years, but at present, it is still relatively rare to really achieve the reality

.

However, when the average level of intelligence of a single building is not satisfactory, there are still many problems to be solved when it is extended to smart Park, urban CIM, and even the ultimate digital twin city.

.

01 the industry with the lowest level of informatization in 2017, Ali released the “white paper on smart building”, which is a research achievement on smart building from the perspective of big data and platform mode, opening the beginning of the “cross-border entry” construction field of large factories

.

However, with the promotion of local policies, the promotion process may be accelerated

.

” Song bin, CEO of Feidu technology, believes that the cost issue needs to be measured from two different perspectives: medium and long-term value and short-term value

.

So far, the informatization of the construction industry as a whole is still “the application level of instrumental and isolated business subsystem hovers”, ranking the bottom in various industries

.

Interestingly, Alibaba, Tencent, Huawei, Xiaomi and other big companies do not seem to care about the “slow growth” of this industry, and they are still increasing their weight

.

In the past, it only focused on important commercial real estate, and gradually expanded to ordinary office buildings and residential buildings

.

If the government issues a document for hard promotion, this part of the cost will be included in the bidding documents and paid by the project bidding unit

.

Some people in the industry have tried some of them, some of them have good results, and some of them still need to be verified

.

” “At present, the use of digital means by large-scale infrastructure central enterprises is more mature, and some infrastructure oriented industrial parks are more and more applied because they prefer prefabricated buildings, but for pure commercial real estate, a single project is really not cost-effective.” Liu Gang calculated an account for taibo.com: “the construction cost of prefabricated building may be 20% – 30% higher than that of ordinary steel structure building

.

“What we need to do now is informatization 2.0, that is, digitization
