Exploring The Real Estate Industry "China'S Intelligent Manufacturing" Is The Right Time

In the era of industrial automation, the housing construction industry with huge economic volume is also actively embracing. However, due to the complexity of the scene and fragmentation of the process, it is still in a relatively early stage.

The policy level is accelerating the implementation process. According to the statistics of Guosheng securities, in 2020, the Ministry of housing and urban rural development jointly issued several papers, vigorously promoting the application of digital technology represented by construction robots and artificial intelligence in the field of engineering construction, thus bringing about the transformation and upgrading of "built in China" to the industry.

Domestic leading real estate enterprises have been in this field for many years. Recently, 21st century economic reporter walked into Shunde, Foshan and found that Guangdong bozhilin robot Co., Ltd. (hereinafter referred to as "bozhilin"), a wholly-owned subsidiary of country garden group, has now completed the automatic landing of construction sites in many scenes.

According to reports, as of February 26 this year, bozhilin has been developing nearly 50 types of construction robots and intelligent products, and 18 types of robots have been pilot applied in more than 15 projects such as shoukai district and Fengtong garden in the robot Valley, with an accumulated construction area of 800000 square meters.

"Robots are accumulating surging strength, and the development potential in the future is unimaginable," Yang Guoqiang, chairman of the board of directors of country garden, who was born as a construction worker, said on different occasions that he hoped that heavy, repetitive and dangerous work in the process of building houses could be completed by robots. "First, it is in line with our pursuit of zero casualties and safety; second, it can improve our quality; third, it can improve our quality It can improve our efficiency. We're going to build our house on the construction site like we make cars. "

Construction sites that are no longer "disgraced"

"China's construction industry has created many of the world's first, but also faced with poor product performance, huge waste of resources, prominent safety problems, serious environmental pollution, low production efficiency and other problems." Ding lieyun, an academician of the Chinese Academy of engineering, said. At present, China's construction industry is large but not good, most enterprises still stay at the level of "moving bricks, binding steel bars, pouring concrete, installing formwork", and the overall application degree of advanced technology and engineering technology is low.

In real life, change has happened quietly. At the beginning of February this year, the Ministry of housing and urban rural development issued the letter on agreeing to carry out intelligent construction pilot project, which confirmed that seven projects in Shanghai, Chongqing and Guangdong will carry out intelligent construction pilot work. It is required to take digital and intelligent upgrading as the driving force, innovate and break through relevant core technologies, expand the application of intelligent construction in all aspects of engineering construction, and improve the quality, safety and efficiency of projects And quality, as soon as possible to explore a set of replicable and popularized intelligent construction development mode and implementation experience.

Foshan Shunde Fengtong garden project is among them. This is the first commercial application project of bozhilin construction robot, and it is also the only pilot project that introduces construction robot and applies it to engineering construction process in batch.

In many construction sites in the robot Valley, the dusty dust that can be seen everywhere in the traditional scene is no longer replaced by floor cleaning robots that cycle around every corner; the manual workers who usually work on the exterior walls at high altitude are also replaced by robots; the manual workers who precisely realize putty and spraying indoors become the issuers, who no longer need to bear the fatigue of long-term head up operation Tired.

"We found that in the interior, workers particularly like these robots for ceiling polishing and putty polishing." Wang Kecheng, assistant president of bozhilin, told reporters that the direct benefit of robots entering the construction site is that they can liberate the work functions of traditional workers from the complicated work without too much technical content, and turn to become technical operators; "the experience is better, the labor intensity is reduced, and there is also a subversive change to the environment." He continued.

More importantly, the problem of labor shortage has been alleviated in the process. China's construction industry continues to grow steadily, but the imbalance is that migrant workers have been in the process of aging.

According to statistics, the newly signed contract amount of China's construction industry in 2020 will be 32517.4 billion yuan, a year-on-year increase of 12.4%. However, according to the report on monitoring and investigation of migrant workers in 2019 issued by the National Bureau of statistics, the proportion of migrant workers over 50 years old accounted for 24.6%, 2.2 percentage points higher than that of the previous year, and increased year by year in the past five years.

For a long time, the overall working environment of construction workers in China is poor, labor intensity is high, mobility is large, and the overall degree of professionalization is low. Accelerating the application of construction robots can not only improve the labor productivity and construction quality of the construction industry, but also help to promote the transformation of migrant workers to skilled workers. In this regard, bozhilin actively cooperates with domestic vocational and technical colleges to provide systematic vocational skills training, so that a large number of construction workers have changed from "migrant workers brothers" to high-quality "modern industrial workers".

Based on the intelligent application of robots in different scenes, bozhilin has also built the BIM digital system application of the whole project, which can control the construction progress and status of all scenes in the project Intelligent Command Center.

Intelligent construction site is not only a policy guide, but also a future construction method that more peers are seeking. Wang Kecheng told reporters that at present, many companies have been in contact with bozhilin and expressed strong interest in the later commercialization. "At this stage, we have more than 10 projects in the world using these construction robots. After a large number of them are used in the group, we will certainly expand to the outside world."

He added that the country garden has an annual new building area of about 100 million square meters, and achieved the application of 800000 square meters last year. It should be said that it is still in the stage of gradual development; however, as it enters the commercialization verification stage, this year should be the outbreak period of bozhilin. "In the future, more types of robots will enter this stage, carry out industrial transformation and provide upgrading services."

In essence, intelligent construction site is a long-term undertaking that tests the overall R & D and landing capabilities more than it seems.

During the national two sessions this year, Yang Guoqiang, chairman of the board of directors of country garden, talked about this aspect in his proposal. He suggested that we should vigorously support the R & D and application of construction robots and intelligent construction equipment, encourage key enterprises in the industry to increase the research and development of construction robots and intelligent construction equipment, and support the key research of relevant core components and key technologies.

At the same time, it is necessary to accelerate the integrated application of BIM Technology in the whole life cycle of construction, and realize the information sharing in the stages of design, procurement, production, construction, delivery, operation and maintenance. Promote the BIM construction approval and construction drawing BIM drawing review mode; and integrate the application of big data and cloud computing technology, establish the construction industry big data innovation center, and realize the industry digital empowerment.

He also proposed to study the establishment and improvement of intelligent construction standard system and evaluation system. Led by the industry authority or leading enterprises, combined with industry research team, experts and scholars, backbone enterprises and other forces, research and establish the standard system of product standards, construction standards, design standards, BIM integrated design standards, assembly parts standards, new construction technology standards, acceptance standards and other standards matching with intelligent construction, so as to provide a comprehensive system for promoting intelligent construction Technical support.

Imagination of intelligent construction

Different from general-purpose scenes such as home use or industry, the construction site scene is extremely complex and fragmented. Behind the arrival of robots in the matching subdivision field, it actually involves the systematic construction of the robot industrial chain and building materials by bozhilin.

Yan Qifan, President of bozhilin Institute of basic technology, told the 21st century economic report that construction is actually an industry with high precision requirements, and it is difficult to find robot parts and materials that can be directly introduced into construction sites from other robot industrial chains that have been commercialized.

"We have contacted a lot of industry chain links, such as navigation companies, building materials companies, etc., but found that we can't run in the construction scene." As construction robots need to be fully adapted, "for example, conventional building materials may be blocked while the robot is running, which needs to be improved by our own research and development," he added

Yan Qifan introduced that in order to realize the Intelligent Implementation in construction sites, bozhilin has been independently developed in many core parts fields, including controllers, servers, drivers, sensors, etc., and almost 100% of the software layer involving the underlying development framework and algorithm can be built independently. "The core value part is adhering to the line of independent research and development."

Data shows that as of February 26, 2021, bozhilin has submitted 3042 valid patent applications, including 2161 invention patents; 984 patents have been authorized, including 262 invention patents.

Among them, the five core systems of construction robot are independently developed, including automatic navigation system, visual algorithm for construction scene, self-developed laser radar and other products and technologies. The advanced nature of these products and technologies has been verified by practical application. The navigation fusion module, laser displacement sensor and intelligent vision sensor have filled the blank in the field of construction robot in the world.

At present, bozhilin has formed 12 product lines of construction robots, including concrete construction, concrete finishing, bricklaying and plastering, interior wall decoration, etc., and most of them can be applied to cast-in-place concrete technology and prefabricated building construction at the same time.

In only two and a half years, bozhilin has realized the construction robot from independent research and development, small batch production to engineering test, engineering service and batch commercial use, and has carried out comprehensive end-to-end planning and practice, and has built a complete full cycle closed-loop.

Professor Zhang Bi, academician of Chinese Academy of Sciences and Dean of Artificial Intelligence Research Institute of Tsinghua University, said: "Country Garden Group has invested a lot of R & D resources and talents in BIM, prefabricated building and construction robot fields, and carried out comprehensive research and development. At present, it has delivered a large number of robots, and has been in the forefront of the field of intelligent construction and construction robots in China and even in the world."

The reason for this is that at present, there is no intelligent transformation in the construction scene among the industries, and it is the same in the world.

According to Cray data, at present, the proportion of domestic real estate enterprises applying intelligent construction in surveying and mapping, design, construction and large complex engineering design is about 10%, 8%, 4% and 26% respectively.

Although Japan, Australia, South Korea, the United States and other developed countries have made some achievements in construction robots, they have not achieved the goal of full cycle and systematic application of buildings. At present, they still focus on single point R & D and small batch trial.

Liao Yuping, deputy director of the construction market supervision department of the Ministry of housing and urban rural development, said that China has made remarkable progress in the development and application of intelligent construction equipment such as general construction machinery, bridge erecting machine and building machine. However, the application of construction robots is still in its infancy in the production of components and parts and on-site construction, and has not yet achieved large-scale application.

"Digital transformation is an important way to promote the high-quality development of the construction industry. From" built in China "to" intelligent manufacturing in China "is the general trend of the development of China's construction industry Liu Jinzhang, vice president of China Construction Industry Association, pointed out. At present, the new infrastructure accelerates the deep integration of digitalization, intelligence and construction site, promotes the upgrading of traditional construction methods, improves project management and production efficiency, and will boost the modernization of China's construction industry into a "fast lane".

"It's a good time for us to study the present." Yan Qifan said that with the rise of digital and artificial intelligence technologies in all walks of life, automation technology is relatively mature, and the construction industry, which is in urgent need of reform, ushers in an opportunity.

"In the future, the construction scene we imagine will be, firstly, the construction robot to help the construction site realize the automation and semi-automation of the standard industrial process; secondly, to build a BIM digital system for the effective visualization of digital and information transmission, on this basis, it will gradually develop towards the intelligent direction; after that, it will realize the overall planning of the construction process, personnel and other details Management. " Wang Kecheng pointed out to reporters that the ultimate goal is to move towards intelligent operation.
