How to "play around" digital transformation in engineering construction?

The management foundation of construction enterprises is relatively weak. Don't digitize for the sake of "digitization", but really realize that data assets are the core value of future enterprises.

In the digital transformation, workers must sharpen their tools first if they want to do well. Unity of thought is the initial intention. They should have ideas, tools and methods. The idea is to make a plan, find out your family background, and ask a professional company to make an IT plan suitable for your own enterprise.

Compared with other industries, the loopholes in the construction industry are still quite large, and the traditional way is not conducive to management. Digital transformation has begun in the era of developed network, and digital management can be used to improve the status quo of the construction industry.

The digital transformation of the construction industry is not a constraint, but to eliminate some hidden dangers, which is more convenient for the management of relevant departments. Common hidden dangers include safety, workers' salary payment, workers' actual attendance, on-site real-time investigation and so on.

The digital platform is used to manage the construction industry, including the real-time entry and exit of workers, the safety situation of each post on the construction site and the weather situation on the construction site.

Zhejiang Jianyi Gong Yi Network Technology Co., Ltd. has a mature digital management platform, which can design functional modules according to the needs of all walks of life. Digital transformation is not only aimed at the construction industry, but also at all industries in the market. The use of digital management can greatly improve management efficiency, and on the basis of reducing costs, it can be better controlled.

In order to solve the problems such as untimely engineering quality and safety supervision, difficult management, isolated application of various business systems, difficult business collaboration, heavy workload at the grass-roots level, poor timeliness of BIM data, and disconnection between BIM and management business data and processes, the GSI-ECM digital platform for engineering construction management developed by Guangdong Ground-to-Air Intelligent Technology Co., Ltd. introduced the lightweight technology of BIM model from the aspect of software intelligent application. Break the barrier of BIM model based on modeling software, realize the lightweight technological innovation on the WEB and mobile terminal anytime and anywhere, establish a set of BIM+ project visual supervision digital platform for engineering construction management, and combine the innovative concept of "technology-management integration" to realize group-level business process reengineering and "true collaboration" to promote digital transformation!

At present, the platform has been widely used in many group-level projects. Focusing on the eight management dimensions of project file management, process inspection, requisition and demolition management, quality inspection management, measurement and payment, construction management, safety management and smart construction site, the platform has optimized the group's project management mode and standard process, and realized the visual supervision presentation of the whole process from design, construction to cost supervision. On the one hand, it deepens the granularity of supervision business, on the other hand, it presents the data of supervision process intuitively. From the aspects of construction process management, relevant supervision and verification, it comprehensively reflects the real and objective whole process control.

Introduction of technical highlights:

First, BIM modeling application:

Introduce advanced BIM technology and draw BIM3D models of various construction sites, including structural models, architectural models and installation models. By using the lightweight BIM engine and REVIT software, the collision inspection of pipeline plane and elevation layout installed in various disciplines is carried out, the comprehensive layout of pipelines is optimized, the clearance is improved, the hardcover elevation is determined, and the drawings of reserved holes are released, which greatly increases the rework cost in the later stage of the site and optimizes the construction progress in advance.

On the basis of BIM modeling, the company innovatively adopts drone tilt photography, and automatically synthesizes the real-life 3D model through software, so as to realize the all-round and high-precision visual presentation of the project, and at the same time obtain accurate measurement data such as height, angle and slope, which is convenient for tracing back the stage information of the project, allowing managers to understand the changes of the project and the surrounding environment, and providing better scheme basis for time limit, cost and safety control.

Second, the project digital management:

The integration of "industry-file-finance" focuses on measurement and payment, and strictly controls on-site construction and engineering data. Only when the site construction is completed and qualified, the engineering data is complete and meets the filing requirements, can the measurement be carried out. With the technical route of "no landing on the whole line, real-time dynamic monitoring", the "completion-filing-account settlement" is realized.

Electronic management of engineering data and documents, unified management of electronic versions of work-related records such as engineering contract documents, work log files, drawings and data files, rectification record files, meeting files, etc., and the combination of BIM model and engineering data by using BIM visualization characteristics can provide data retrieval from construction latitude and improve data retrieval efficiency. The system automatically calculates, evaluates and summarizes the quality assurance information of the project, and carries out online circulation combined with electronic signature, so that the examination and approval work can be completed on the same day and the efficiency can be improved by about 50%.

The quality inspection evaluation data submitted by the quality inspection module on site will be automatically synchronized to the archiving module, and the data will be automatically summarized and archived, which greatly improves the timeliness of engineering data sorting and archiving. The comprehensive efficiency of archives has increased by 86%-92%. Fill in the form online, flow online, automatically generate the measurement report system, push the measurement process data and the font of the completion status system, and improve the efficiency of measurement audit by more than 70%.

Taking the project schedule management as the main line, the basic information of the project and the functions of the safety and quality management module are connected in series. By entering the progress data and binding the actual construction nodes of the project, the planned progress can be compared with the actual progress, and the reasons for the lag of the project progress can be analyzed more objectively and efficiently.

Input and manage the basic information of the project and the personnel information of the participating units, which reduces the labor cost and repetitive work. Integrate and manage project safety and quality management measures, inspection standards, hidden danger investigation list, problem registration and handling, rectification supervision, etc. , and use the problem integration and closure function of the platform mobile app to find problems, take photos, describe problems, send them to relevant responsible persons for rectification, and track the rectification and closure of problems online. The constraint components of the online rectification process for safety and quality problems can be traced back later.

Third, the visual management of land acquisition and demolition:

In the early stage of the project, the land acquisition and demolition management personnel can quickly understand the overall demolition situation and the surrounding environment of the project by using the inclined photography model combined with the red line of the project, and allocate the land acquisition and demolition work. In the phase of project requisition and relocation, the requisition and relocation personnel can locate the location of the site personnel in real time and analyze the current area or housing requisition and relocation scope through our requisition and relocation applet, which is convenient for the site personnel to communicate and coordinate with each other.

In the project implementation stage, according to the data of the on-site requisitioners, the ledger of land acquisition and demolition of this project is formed and imported into the project management platform as the data basis for the joint analysis of land acquisition and demolition. In the management stage of combining digital and analog, we can associate the geographical location data of land requisition and demolition ledger with our BIM+GIS platform to realize the three-dimensional visualization of land requisition and demolition information, and transform the traditional two-dimensional data into three-dimensional intuitive visualization information.

The land acquisition and demolition management personnel of all participating units do not need to spend a lot of time and energy to obtain information on the spot. They can quickly and intuitively understand the data of house demolition, land requisition and pipeline relocation of the project through BIM+GIS platform, and can intuitively understand the location, surrounding environment, land requisition and demolition area of the project. Greatly improve the work efficiency and quality of managers. The intuition and convenience of three-dimensional visualization can improve the efficiency of communication, management and coordination between the contractors and the competent authorities, which is conducive to the promotion of project relocation and demolition, and reduce the delay of construction progress caused by lagging management and coordination.

Fourth, intelligent IOT technology:

Through IOT technology, all kinds of special operation equipment, such as site safety helmet, concrete inspection, car washing, environmental protection inspection, entrance gate, tower crane, crane, edge guardrail, etc. , managed by IOT sensing equipment, and the daily status and operation data of each equipment are converted into analyzable data through wireless IOT transmission means, which are transmitted to GSI-ECM digital platform for engineering construction management in real time and converted into chart analysis. Monitoring and displaying according to time period, type and division, and further data mining and analysis will provide real and objective basis for equipment maintenance, environmental governance and optimal management, and greatly improve the efficiency of management decision-making.

Five, multi-dimensional monitoring technology:

Through multi-dimensional video monitoring management, such as multi-point control of on-site monitoring equipment, multi-directional control of high-altitude ball machine, panoramic view of unmanned aerial vehicle, aerial photography, etc., scientific design and accurate layout can be realized, and uninterrupted real-time high-definition monitoring of important sites, four ports and five sides can be realized, so as to reduce practical problems such as labor disputes in on-site construction, ensure the safety of people, property and materials in the construction site, and provide strong video evidence support for on-site safe construction, civilized construction and process management.

Six, the cockpit command and operation center project-level big screen

The project-level big screen in the cockpit command and operation center mainly displays real-time management data such as project overview, investment status, output value progress, safety control, quality inspection, requisition and demolition. By capturing data such as personnel, progress, quality, safety, requisition and demolition in project management, connecting data such as cost system, file system, measurement system and on-site IOT equipment, data are stored, mined, collected and requisitioned by using data management and blockchain technology.

Integrate the data of safety and quality management, schedule management, environmental detection, investment output value management, land acquisition and demolition management, equipment management and other modules for mining and analysis, so as to facilitate the project manager to grasp the project construction site data in time and assist the project leaders in making decisions.

In the next step, Guangdong Ground-to-Air Intelligent Technology Co., Ltd. will continue to take the Internet of Things, blockchain, cloud computing, BIM lightweight application engine and big data as technical support, further promote the optimization and application of the information platform, strive to maximize the application value of the platform, empower value-added smart construction and lean construction, and provide technical force for the Group's engineering quality improvement and high-quality development.

With the update and iteration of computer technology and the deep integration of information technology, digitalization has increasingly become the most important asset today. According to the data of China Information and Communication Institute, the scale of China's digital economy exceeded 3 1 trillion yuan in 20 18 years, with a year-on-year increase of 14%, accounting for about 34.4% of GDP. With the integration of big data, cloud computing, Internet of Things, blockchain, BIM, VR, AI, 5G and other new technologies, the field of engineering construction is gradually changing to digitalization, virtualization and informationization. For engineering construction, whether it is the incremental market based on the integrated application of new generation digital technologies such as big data, blockchain, artificial intelligence and digital twins, or the stock market for the transformation and upgrading of traditional industries, it will usher in the strategic opportunity period brought by the digital economy. At present, more and more digital technologies are applied to engineering construction, which runs through the whole life cycle from design planning, design engineering, construction to operation and maintenance.

With the deepening of digital strategy and "internet plus", engineering buildings will develop into intelligence and data, and construction and operation and maintenance technologies will be paid more and more attention. Therefore, how to use BIM data platform to build project data and how to refine and streamline the data will have a far-reaching impact on the project. As the foundation of BIM technology, intelligent analysis of big data has 4V characteristics of quantity, speed, change and value, which makes it quantifiable, measurable, comparable and evaluable. Big data in the digital age is not only simple digital superposition and collection, but also the mining and effective integration of value information, which requires the integration of personnel, process systems and software and hardware resources.

When it comes to engineering construction and digitalization, we have to think of three-dimensional laser scanning technology. The most essential application of three-dimensional laser scanning technology in engineering construction is the acquisition of field data, which is different from traditional point measurement. It is the big data of construction projects, any measurement, actual measurement, construction node comparison, model modification, completion delivery, data retention, quality inspection, etc. Are based on this kind of big data, resulting in many applications.

Compared with the traditional single-point measurement, the three-dimensional laser scanning technology is also called a revolutionary technical breakthrough from single-point measurement to surface measurement because the three-dimensional laser scanning system can densely obtain a large number of data points of the target object. Its appearance makes the application of engineering big data in many industries possible. Such as reverse engineering and comparative testing of industrial measurement; Displacement monitoring and topographic mapping in surveying engineering: data archiving and restoration projects in archaeological projects; Completion acceptance, reconstruction and expansion design in construction projects.

3D laser scanning technology can perfectly provide a true color 3D point cloud model of 1: 1 in the initial stage of engineering construction planning, including topography, traffic lines and surrounding buildings.

How can we ensure that the information obtained is more comprehensive? Then the hardware facilities are very important-you need to use a high-precision three-dimensional laser scanner to obtain data and provide accurate basis for planning and design.

FRAO FOCUS PLUS 350/ 150 is very adaptable to the environment and can be easily used in mountain roads, factories, bridges and scenic spots. The accuracy can reach millimeter level (1mm accuracy). It is a large-space digital acquisition device, which is very suitable for digital application in the field of engineering construction.

"Digitalization" is everywhere and is needed by all walks of life.
