It is stored in the server, and managers and practitioners in each specialized field of the plant construction project connect to the same cloud server and dataize necessary actions such as handwriting management. It relates to a process management system and method using a smart construction platform capable of generating more innovative efficiency of work.

BIM (Building Information Modeling) refers to the process of virtually modeling facilities in a multidimensional virtual space from planning, design, engineering (structure, equipment, electricity, etc.), construction, and even maintenance and disposal. In particular, it enables the design and construction of state-of-the-art design and eco-friendly energy low-cost buildings, which are recent issues, and is a concept similar to multidimensional virtual design construction (VDC). Recently, internationally, as the scope of application of BIM covers all construction environments as well as the construction field, it is widely used in civil engineering and plant fields in Europe and the United States.

Building in BIM (Building Information Modeling) means the entire life cycle of the target building - design, construction, operation and management, and information means all information included in the entire life cycle of the target building, Modeling refers to an integrated tool and platform that provides production, management, and publication of all information included in the entire life cycle.

BIM creates numerical data by converting buildings into data, and a three-dimensional display effect can be seen. Data of the length connecting the start and end points of the line are generated, not simple line and face work, and the area is dataized as the standard of the closed face. And by combining the data of length and area, volume data can be obtained. BIM recognizes the relationship between building objects, such as walls, slabs, windows, doors, roofs, stairs, etc. Regardless of whether the building to be designed is standard or irregular, information at all stages is integrated and managed and utilized through compatibility and sharing of data generated during building construction by project and process.

As the demand for 3D building models increases worldwide and the fields of application using 3D building models diversify, the importance of a platform that can service spatial information in units of city models using 3D building models and topographic information is increasing. is being highlighted. And since the city model consists of numerous buildings, a quick and efficient visualization method of the 3D model is becoming an important factor. In particular, when performing screen display of a large-capacity 3D object using equipment having limited performance, such as a mobile device, a smooth operation is impossible due to a limitation in rendering performance. In order to solve such a problem, a technology for lightening data through detailed level (LOD) model configuration for a 3D live-action model is essential.

The detail level, that is, LOD (Level Of Detail) usually refers to the level of detail when modeling information. If the composition of the Level of Detail (LOD) model is not clear, it can lead to a lot of confusion when modeling construction information among stakeholders.

The basic idea of the level of detail (LOD) is to use a more concise representation when an object is small or has nothing to contribute to the rendered image. For example, a detailed 3D object model consisting of approximately 10,000 triangles is used when the observer is close to the object. When the observer moves away from the object, just using a simplified model consisting of about 100 triangles can look almost similar to the original model because of the distance.

Currently, the 3D program commonly used in plant construction is a program up to LOD 200, and the basic design and 2D drawings for each specialized field are extracted and constructed.

Plant construction works by redesigning the necessary contents separately based on the basic design contents of LOD 200. A company in each specialized field separately redesigns and manufactures construction and then delivers on-site installation. During on-site installation, a lot of interference with products from other fields occurs. There are a number of things that happen.

As for the pipe support, the construction work is done at the LOD 100 stage and the entire site is customized, which increases the cost and causes a lot of delays in the process.

Due to the basic design drawing of LOD 200 for electrical instrumentation piping, the electrical instrumentation company prepares and constructs 2D drawings and installation drawings, so the construction does not proceed as planned. A lot of work is being done.

In the case of electrical instrumentation support, a person with current experience identifies the actual steel structure at the installation site and then customizes the instrumentation support to the site based on experience. Since the electrical instrumentation support is simpler to manufacture than other fields, the field installation is faster than other fields. Therefore, installation work always takes precedence over general piping. During the post-process general piping installation work, electrical instrumentation piping or electrical instrumentation piping support is installed at the location where the general piping should pass, resulting in many on-site corrections.

In addition, there are many changes in plant construction, such as changes in machine direction and changes in customer requirements during construction. In the event of such a change, the contractor changes all related drawings according to the content of the change and sends it to each specialized field after publication. Companies in the specialized field receive these changed drawings, revise the corresponding contents, and proceed with the work order. There are many cases in which the design manager of a construction company omits revision of one of the related drawings as a management member, or overlooks and issues revisions among related drawings. For example, there are many cases in which 30 correction points for the pipe should be corrected, but only 28 of them are corrected. At the time of publication, companies in each specialized field have no way to check the missing 2 points. Because detailed design is done only by each individual, the steel frame only looks at the steel frame, and if there is no interference between the steel frames, the steel frame judges that it is just right and proceeds with construction. Because the pipe works in 2D, the interference section is checked only after it is installed, so it is difficult to review the interference in advance, so a lot of on-site correction work occurs.

Field change notices (FCNs) are dealt with on-site corrections, resulting in increased construction costs and delays in the construction process. To solve this problem, virtual construction is completed by integrating the contents of all fields in the same plant project, and all contents are managed in an integrated way.

Currently, process management tasks in all specialized fields of plant construction are dedicated to Microsoft's Excel, and each individual is responsible for creating and managing data independently. Due to this, it is difficult to cooperate in work in the steel frame process, and it is difficult to share errors and real-time due to writing and managing data manually. There is a negative impact on the environment due to the difficulty of loss and data sharing in management using paper documents, and excessive use of paper.

On the other hand, in the current plant construction site, there is no part about statistics. Office management receives each process from the person in charge of each process, collects Excel files, and uses the collected data to create tables or graphs in Excel. , problems, and collaboration are not possible and, most importantly, performance evaluation is difficult.

The process management system and the method using the smart construction platform according to the present invention make it a Dash Board for manpower management, equipment management, process management, weather, announcements, progress rate and statistics of the entire process, so that users have trouble finding a lot of data one by one is removed, and more detailed dash board is displayed by clicking each statistical data on the full screen of the dash board. By displaying this, you can see the simplified data of management and display the data you are looking for at a glance without having to search the internal data one by one, so you can quickly implement real-time processes and responses.

The current work report at the plant construction site is a very important task, and it is a task that must be prepared and kept every day in order to write and share the work that happened today at a glance. The person in charge of the construction directly receives input manpower, manpower allocation, equipment usage, quantity counting, today's work history, last day's work history, special matters, etc. from the person in charge, and the person in charge of the construction collects it. , and even that, there were many problems because accurate data did not come.

In order to check the shipment at the current plant construction site, a local worker checks the products loaded on the vehicle of the product one by one, writes it on paper and delivers it to the construction manager, and the person in charge of the construction writes the contents in Excel and transports A method of calling the company to receive the vehicle's personal information and other documents, printing it out and transporting it. At the place where the transported product is received, it is confirmed by signing the paper document, and the paper document is brought back to the person in charge of the place where it is shipped. is checking for delivery. When using the current method, it is frequent to come and go because of vehicle paper documents, and if you want to find out what products were received or shipped in other processes, you have to look at the paper documents as well, and collaboration between processes due to the loss of paper documents is difficult. not being done

The deepening step of BIM modeling described below may be performed by the data generator.

BIM

BIM refers to the task of digitally realizing a “three-dimensional model” containing various information in a virtual space. In particular, the key element of BIM is a technology that contains accurate construction information, and the goal of successful BIM is to purify architectural design information by life cycle, and to share information with practitioners at each stage of the project.

Advanced stage of BIM LOD (Level of Development)

In order to utilize BIM more efficiently, the information stages can be arranged according to the process of constructing the BIM virtual shape with LOD (Level of Development), which is an advanced stage of BIM. The advanced stage of BIM LOD is a system developed from the 'Level of Detail', which was originally created to build an automated system for precise facility management and quantity calculation. As the importance of ‘Level of Information’ for managing not only geometric information but also non-geometric information in BIM was emphasized, LOD was developed by combining ‘Level of Detail’ and ‘Level of Information’. Therefore, LOD in the advanced stage of BIM is a fusion of building shape and information, and it helps project-related practitioners to implement clear construction and construction management in accordance with the design and construction process. Intensive stage of BIM LODs can be explained by dividing them into six stages according to the construction process.

- LOD 100 : Planning and Design Pre-Design Stage

- LOD 200 : Concept Design Schematic Design Stage

- LOD 300 : Basic Design Detailed Design Stage

- LOD 350 : Detailed Design Construction Documentation

- LOD 400 : Construction Supervision Design Construction Stage

- LOD 500 : Maintenance Facilities Management Stage

LOD 100 : Planning and Design Pre-Design

The LOD 100 level BIM is created to support the feasibility study to prepare for the start of the project, and the model contains the most basic information of the building. In this period, the direction of the business is defined, and the business funds are secured for the contracts related to the business.

The BIM model at this stage contains macroscopic data such as cadastral maps, urban planning maps, and survey maps to understand the project site. Build a model in the form of accumulating information necessary for understanding. Generally, the more complex and large-scale projects, the earlier it is recommended to contract with business-related companies to establish an agreed BIM model.

LOD 200 : Conceptual Design Schematic Design

BIM at the LOD 200 stage is the stage at which building design begins according to the requirements of the owner or business owner. BIM at this stage should contain the intention and design concept of the project, and it is the stage in which the information of BIM is organized so that overall information such as architecture, structure, materials, and facilities can be discussed and decided.

Typically, formal drawings begin at this stage, and if necessary, bird's-eye views for publicity and publicity are created in order to secure additional funding with the three-dimensional shape of the BIM.

LOD 300 : Basic Design Detailed Design

BIM at the LOD 300 level is the BIM in the process of developing a conceptual design and moving on to a detailed design. This is the stage in which the results discussed in the conceptual design are arranged in detail, and information about the shape and materials of the building is decided. At this stage, the detailed three-dimensional shape and system begin to be determined, and it is desirable that there be no major change in the external design after that.

Therefore, at this stage, information on the size, shape, and quantity of materials begins to be confirmed in BIM, and it is desirable that information on structures, piping, electricity, heating, ventilation, energy analysis and other systems be frequently shared with collaborators with BIM. BIM way of working. After this stage is completed, the design of the BIM will be materialized, and information on the estimate of the quantity will be established so that alternative project costs can be identified.

LOD 350 : Detailed Design Construction Documents

The two main purposes of BIM at LOD 350 are to obtain building permits from cities and authorities, and to establish BIM for construction to actually construct buildings that are still virtual. Therefore, BIM is divided into BIM for permission and BIM for construction, and work is carried out. BIM at this stage consists of the detailed design BIM built in architecture, civil design BIM and structural design BIM in a linked state.

When composing BIM at this stage, there are many cases of interference between shapes because different types of BIM shapes are merged or connected into one. Therefore, a detailed review process is required at this stage. The drawings output at this stage are legally binding, so the BIM shape must be formed in compliance with the building law.

LOD 400 : Construction Supervision Design Construction Stage

In BIM at LOD 400, shapes are formed as they are built. BIM at this stage includes manufacturing, assembly and detailed drawings as well as quantity, size, shape, location and orientation.

In this stage, the virtual shape formed by BIM should be constructed as closely as possible to reality to reduce the construction period or additional construction cost. At this stage, BIM is effective only when the shape is precise, and depending on the project, there are projects where the construction error must be within 3-4mm. At this stage, in order for the virtual shape of BIM to be constructed with the minimum error in reality, cooperation and smooth consultation with the contractor must be made. At this stage, based on the BIM-based BIM-based construction management and growth-type construction operation, at this stage, if the system is built, it becomes a BIM close to a digital twin. It is still difficult to respond to and respond to all the variables that occur every moment with BIM, but by building As-Built-BIM for each important process process, accurate and precise manufacturing and assembly required in the LOD 400 stage can be proceeded.

LOD 500 : Maintenance Facilities Management Stage

LOD 500 BIM is the core of LOD 500 BIM to identify essential information for effective maintenance and management after construction and to make BIM into a powerful digital asset. At this stage, if only the necessary information is extracted according to the client's request and the efficient use of space and operation of mechanical facilities is established as a real-time management system, it becomes a digital twin.

At this stage, if the structure safety management and maintenance information is systematized and a digital twin capable of monitoring structure danger signals with live measurement sensors is established, it becomes SHM (Structural Health Monitoring).

When a large-scale repair or reinforcement of a building or facility is required, an As-Built-BIM that reflects the construction error of the building is established. Many people know the LOD 500 level as As-Built-BIM, but As-Built-BIM is not a concept included in the LOD 500 or a limited name. As-Built-BIM is established in the previous LOD stages and efficient construction is carried out in many cases, and the efficiency of the overall project is increased by using the previously efficiently constructed As-Built-BIM. Therefore, it is a misunderstanding to refer to BIM belonging to this stage as As-Built-BIM.

As-Built-BIM and Modeling Accuracy LOA (Level of Accuracy)

In order for BIM to be used not as a simple three-dimensional atypical design tool but as an effective building information integrated management system, it is necessary to establish a proper BIM. Only then can an existential database be formed that can be used to extend the overall building life cycle, streamline support procedures including cost management, manage construction sites, and manage facility operations. It is also possible to build partial or temporary As-Built-BIM, so it is a wise BIM operation method to flexibly apply to the project as needed. As-Built-BIM refers to BIM in which construction errors including actual building location information are reflected, but construction errors always exist. Even if an As-Built-BIM is built using a high-precision 3D scanner, it is impossible to completely eliminate the gap between construction error and design data error. Therefore, it is necessary to discuss in advance how much precision and precision, and how much precision level LOA will be used to build BIM.

As-Built-BIM Accuracy and Precision

Before understanding and putting into practice the As-Built-BIM modeling accuracy LOA (Level of Accuracy), it is necessary to have a basic understanding of the accuracy and precision of data. Everyone wants precise and accurate data, but in reality, it is impossible to obtain perfect data without any errors. In acquiring data, environmental errors such as weather, temperature, and wind always exist, and no matter how high-end measuring instruments are used, mechanical errors exist. Therefore, the data obtained by the measurement situation and the machine used may be precise but not accurate, and conversely, the average data may be accurate but not precise. Therefore, in order to properly utilize the modeling accuracy LOA of As-Built-BIM, it is necessary to understand precision and accuracy.

Data Precision

Precision is called repeatability, and it refers to how consistently similar values are measured when measurements are repeated. Precisely acquired data refers to how densely the measured data are distributed, and the relationship with the target actual dimension is almost irrelevant. The degree of similarity between each measured data is a measure of precision. For example, when measuring 10.0mm, the measured values of 11.2mm, 11.3mm, 11.2mm, and 11.3mm are more precise than those of 10.1mm, 10.3mm, 10.1mm, and 9.8mm. In case it is precise but deviates from the actual value, it should be possible to obtain the desired accuracy through the measurement method or calibration of the machine.

Data Accuracy

Data with high accuracy have little bias in values, and values close to the target actual value are surveys. In other words, accuracy indicates the reliability of the data, and it is an important measure for building As-Built-BIM because it means how closely the point cloud data acquired when using a 3D scanner is distributed with the actual shape. Since a high-accuracy machine becomes more similar to the actual phenomenon as the amount of data is large, PCD similar to the actual shape can be obtained as much data as possible with the 3D scanner is acquired. When acquiring data from the actual field, the critical section spends more time to acquire more PCDs meticulously and densely, increasing the accuracy of the data to build As-Built-BIM closer to the real thing.

Modeling Accuracy LOA (Level of Accuracy)

Accuracy refers to the deviation of the difference between the measured value and the true value. In other words, modeling accuracy LOA refers to how close the virtual shape is to the real shape.

As the project progresses, it is important to clearly define how much the virtual shape will be built to match the real number, depending on the needs. Only then can the project workers share unified information and the project can proceed smoothly. The American Institute of Construction Documentation (USIBD) defines modeling accuracy LOAs in five levels.

- LOA10 error rate 50mm or more

- LOA20 error rate 50mm ~ 15mm

- LOA30 error rate 15mm ~ 5mm

- LOA40 error rate 5mm ~ 1mm

- LOA50 error rate less than 1mm

If you build As-Built-BIM with 3D scanning, target LOA30 or LOA40. Even if precise equipment is used to build a model to which LOA50 is applied, it takes a lot of time and manpower, so the efficiency is low.

It is necessary to build As-Built-BIM by accurately separating the definitions of LOD and LOA in data generation using BIM. Depending on your needs, there may be projects with LOD300 but LOA40, and projects with LOD500 but LOA10 may be more efficient. A wisely built As-Built-BIM will be a powerful asset for the project and will create new value for the building.
