Description

Method and Apparatus for Safety Information Generation by Reading Daily Job-site Work Reports in Construction and Industrial Project}

The present invention is intended to prevent safety accidents that occur during construction at construction and industrial construction sites. More specifically, the present invention uses a large amount of construction progress information from the daily work compensation written every day by multiple partners of temporary civil engineering, construction, and electrical equipment, and uses the control unit. It is about analyzing risks in cases where parallel work and preceding work are not completed or succeeding work cannot be followed for all work on site, so that preventive measures can be taken in advance.

The number of deaths per 100,000 people in OECD industrial accidents is 3.0, and in Korea it is 7.0, which is twice that of the OECD (JoongAng Ilbo 2017.08.28).

According to the 2016 industrial accident status announced by the Ministry of Employment and Labor, the total number of industrial accidents is 90,656, which means that more than 10 accidents occur per hour. Among them, the number of construction accidents was 29.3% compared to all industries, and the total number of fatal accidents was 1,777, with more than 1 death occurring every 5 hours. The number of construction deaths was 31.2% compared to all industries.

In 2016, the number of deaths from accidental disasters was 969 across all industries, and among them, the number of fatalities from accidental disasters in the construction industry was 499, which was 51.5% of all industries (Construction Economy 2017.05.25).

In order to prevent accidents that occur during construction at construction sites, efforts are being made to provide worker safety education, implement a system to evaluate risks before starting work, improve related systems, expand facility and human investment, and strengthen penalty points and punishments.

Despite these efforts, it is believed that the reason why disasters have not decreased is due to the following reasons.

With the development of construction technology, the construction of high-rise buildings and high-rise apartments rising high into the sky has increased, and along with large shopping malls and large-scale factory complexes that spread horizontally, construction digging deep underground is increasing.

As a result, the number of workers is up to several thousand per day, distributed vertically and horizontally over a large space, and the work of tens or hundred or more temporary building electrical facilities is progressing in a complicated manner, making it difficult for construction workers to manage their work. There are limits to expanding personnel.

While the subjects that need to be managed for safety have become vast and complex, the traditional management method by manpower is maintained.

For example, manpower-centered safety management occurs when managers lack construction experience, when there are safety problems in a specific space but are not aware of them, when there are mistakes, when safety facilities are dismantled or moved without permission, and when communication between preceding and following construction workers is poor. This includes workers entering restricted areas without their knowledge, and not having proper safety facilities in place.

The following is a contribution from a safety expert.

As any safety-related expert knows, among the four principles of disasters is the principle of causal linkage. All disasters have a cause. The most unfortunate thing about construction disasters is that no matter how much the injured person worked in compliance with safety work procedures, a disaster may occur if incorrect working conditions were created in the preceding process.

Such examples occur in most cases of construction disasters (Construction Economy 2017.05.25).

It is judged that the above conventional safety management methods are unable to manage vast and complex tasks, safety facilities, equipment, and workers based on limited manpower and experience.

Safety management-related documents include risk assessment, hazard prevention plan, night work permit, work daily report, etc.

First, the risk assessment process proceeds as follows.

When preparing a hazard prevention plan, safety management plan, or construction plan at the beginning of construction, an initial risk assessment is conducted, a risk assessment form is prepared considering the site situation before the work, and the work is divided into detailed units from the introduction of materials to the discharge of construction materials. Create a schedule.

Once unit work is divided, risk factors (human factors, mechanical factors, electrical factors, material factors, work characteristics factors, work environment factors, etc.) for the work are identified. Safety measures that can be taken on site for the identified risk factors are established and the risks are determined through review by the author, construction manager, and safety manager.

A risk assessment meeting is conducted the week before the start of the relevant construction work (participation by the construction partner, construction company construction and safety staff, and site manager). Determine when and who will take action and confirm safety measures for the selected risk factors, and provide delivery training until the day before work begins.

Meanwhile, the risk assessment report is important and evaluates a portion of the overall work, focusing on work with a high risk level, and the evaluation content is written according to the individual capabilities of the partner company.

Therefore, the risk assessment does not cover the entire work, so there are some tasks that have not been evaluated. In particular, during the finishing construction period, such as interior design, numerous tasks are carried out simultaneously, so a lot of time and effort are spent on writing risk assessments and evaluation meetings, so there is no choice but to select and manage only major tasks.

In addition, the content of the evaluation is highly subjective, depending on the writer's ability of the partner company.

It is difficult to comprehensively know the status of the work being evaluated in a time series by date, and it is difficult to comprehensively describe it as a parallel work, preceding work, and subsequent work that has a precedence relationship with a specific work. Among the dozens of partner companies, it is difficult to write an evaluation form in the case of an office with only a small number of employees or a construction company without a computer.

Another safety management task is writing work reports.

The work log is a construction record written in text format by dozens or hundreds of partners participating in construction, including temporary civil engineering, architecture, electricity, and equipment. The work daily report includes the work performed the previous day and the work performed today, and also includes the number of personnel on duty and the number of equipment.

The purpose of writing a work log is to simply know which partner company is doing what and where.

The work diary has the advantage of requiring less time and effort to write because it copies text sentences describing the previous day's work, pastes them into today's work, and then edits and adds them. It also has the advantage of requiring less time and effort to write, and allows partners to use the on-site PMIS or word processor Excel program. I am writing.

On the other hand, the work diary has the disadvantage of making it difficult to comprehensively understand the overall progress because the contents are scattered in pieces and by date, like a tile mosaic on a wall.

In addition, since each partner company writes one page, the content is so extensive that it becomes dozens of pages or more during the finishing and interior construction period, making it difficult to view the entire document comprehensively.

The work daily report is not written for the purpose of safety management as it is a brief description of where each partner company is doing what work and how many people are doing it today.

Conventionally, risk was evaluated mainly on major tasks, but the present invention introduces the concept of a complete investigation that evaluates risks for all tasks in the field. This is because safety accidents occur not only in major work but also in minor work.

Conventionally, the cause of a disaster was identified based on visually visible problems in a specific space, but in the present invention, in addition to the conventional analysis method, the causal relationship between preceding and succeeding tasks that affect work is comprehensively analyzed in a time series.

It allows risk to be determined quantitatively and immediately from objective and systematic safety standards verified in advance by multiple experts, rather than traditional safety management centered on individual experience and ability.

In order to solve the above-mentioned technical problems, the present invention evaluates the risks of equipment and temporary materials necessary for partners to work.

Define what other dangerous concurrent tasks may occur in the same workspace.

By analyzing the impact of preceding and succeeding tasks, we comprehensively analyze in a time series what state the preceding and following tasks must be in to ensure that the current task is safe.

In order to determine whether a specific task is dangerous, risk assessment standards are established through objective data, laws, regulations, cases, and expert opinions.

Standards for safety facilities (height, strength, size, time of installation, retention period, time of dismantlement), standards for working conditions (temperature, humidity, wind, toxic gas, lighting, electric shock, pressure, etc. working conditions for building temporary electrical facilities) , schedule differences with the preceding task (a condition in which the preceding task must be completed), and schedule differences with the successor task (a condition in which the subsequent task must follow).

These data are classified by type and task and converted into a database.

The method of collecting work information utilizes the traditional work log without any additional effort or institutional manpower.

The work log records the work details of all partners on a daily basis, so it includes almost all work on site and is accurately written by officials, so it is highly reliable and faithful in content.

In order to have a more comprehensive understanding of how construction progresses, the contents of specific tasks distributed by date from the work log are collected in one place and created by date. The contents include the location of the work, work details, number of workers, progress rate, etc.

The risk assessment is conducted by the control department by comprehensively judging how dangerous the environment surrounding the work set in the safety standard setting stage is based on the analysis from the work log.

According to the present invention, the following effects can be expected.

Conventionally, risk was evaluated only for high-risk or major work, but according to the present invention, risk can be evaluated for almost all work performed at construction sites and industrial sites. A full investigation can be conducted on all work.

In addition to existing safety management activities, risks can be analyzed systematically and immediately just by creating a work report as usual without investing additional manpower, effort, time, systems, or systems.

Previously, risk assessment was highly subjective, with the content varying depending on the individual evaluator's capabilities. However, according to the present invention, objective and systematic safety standards, such as opinions of expert groups, laws, regulations, safety standards, and cases, are prepared in advance, so risk assessment is refined.

Previously, work logs were used to check work status or keep records. However, according to the present invention, it is possible to comprehensively grasp on-site status information by utilizing the lowest-level work details and personnel and equipment information contained in the work log.

In the past, the start and completion progress status was managed mainly for some major tasks, but according to the present invention, construction records by date can be created for all work on site.

Previously, work reports were written by date, so in order to know the preparation, start, and end of a specific task, you had to read and organize the contents of the specific task by date. However, it was difficult to organize it comprehensively because the content was vast and required a lot of manpower, time, and effort.

According to the present invention, the control unit reads the daily work contents and synthesizes them comprehensively, so that work information is quickly and accurately synthesized in a time series.

You can simultaneously know how many people are working on a specific floor, location, or space, as well as the level of risk that space has. Therefore, dangerous spaces with many workers can be identified in order, and disasters can be minimized through intensive management.

In the past, it was difficult to analyze preceding or succeeding tasks that put a specific task at risk, and even in the case of analysis, analysts analyzed manually, which took a lot of time and effort, and the content was also highly subjective.

According to the present invention, it is possible to accurately determine how a preceding or succeeding task related to a specific task will affect the status of the current task. As a result, it became possible to systematically analyze not only the problems of the specific work itself, but also the relationship with the external environment surrounding the specific work (other types of work, preceding and following work, up, down, left, and right tasks).

The present invention conducts a thorough investigation of all work carried out in the field. By synthesizing scattered and fragmented information, daily information about the work is completed. Since the history of all work can be known, a comprehensive judgment can be made. Quantitatively analyze how dangerous the current state of the work is by comparing it with objective standards.

Comprehensively evaluate how much the task is currently affected by identifying the status of predecessor and successor tasks related to the task. These processes can be quickly and accurately collected, organized, synthesized, and evaluated in real time according to pre-written procedures and standards to manage risks for all work taking place in the field.

As a result, problems that cause safety accidents and disasters can be continuously eliminated.

Hereinafter, an apparatus and method for generating safety information using a work log according to the present invention will be described in detail.

Figure 1 is a block diagram showing the configuration of a safety information server 20 and a terminal 10 that generate and provide safety information using a work log according to an embodiment of the present invention.

Referring to Figure 1, the safety information server 20 using the work log according to this embodiment is responsible for receiving safety information, determining it, and providing it to the terminal 10. The terminal 10 is responsible for inputting and searching work reports or safety information.

Figure 2 shows the configuration of a safety information generating device using a work log according to an embodiment of the present invention.

Referring to FIG. 2, the functional configuration of the safety information server 20 according to this embodiment includes a control unit 21, a safety standard database 22, a job daily report database 23, a job information database 24, and a safety information database. Includes (25).

The control unit 21 stores the safety-related standards of the safety information server 20 in the safety standard database 22 and stores the work log in the work log database 23. Then, work contents are read from the work daily report database 23, work contents for each day of a specific job are created, and then stored in the work information database 24. Afterwards, a risk assessment is performed and the resulting data is stored in the safety information database 25. It is also responsible for transmitting the contents of the database to the terminal 10 according to the user's request.

The safety standards database 22 stores safety standards for specific tasks. For example, the job title is septic tank cleaning, and the safety standards and rules include measuring oxygen and harmful gas concentrations, performing ventilation, and wearing a respirator or oxygen mask.

When the concentration of hydrogen sulfide reaches 20 to 30 ppm, olfactory nerve cells become fatigued, and even if the concentration increases beyond that, it is not felt. At a concentration of 100 to 200 ppm, the olfactory nerve is paralyzed, the aversion to hydrogen sulfide is reduced, and the vigilance to higher concentrations of hydrogen sulfide is lowered, thereby losing the opportunity to escape from danger. If the concentration of hydrogen sulfide exceeds 700ppm, it exceeds the oxidizing capacity of the blood and attacks nerve cells, resulting in neurotoxicity.

The safety standard database 22 also stores conditions of preceding or succeeding operations for a specific operation. For example, when working on a specific equipment type, it is important whether the valve was closed in the preceding work. If the valve is temporarily opened and not closed, an explosion or pipe may burst during subsequent work.

As a condition of follow-up work, if a specific work involves spraying insulation on a material with a high fire risk, the work of applying fire-resistant material surrounding the painting material must follow. If follow-up work is not started or is delayed, the insulation coating will be significantly exposed, increasing the risk of fire. Set the schedule difference or process rate difference between the current work, spraying insulation, and the subsequent work, applying refractory materials. Since these differences may vary depending on the number of floors, area, etc., it is advisable to set them in consideration of site characteristics.

The work daily report database 23 stores work daily reports written by partners for each type of work, such as temporary civil engineering, construction, electrical equipment, etc. The work daily report is created in the Excel file, Hangul file, Word file, and PMIS web page. The work log includes a risk assessment form and other documents describing work details. The work daily report uses the work daily report prepared conventionally.

In the work information database 24, the control unit 21 reads daily work details for a specific job from the work daily report database 23 and stores the information organized in a time series. For example, the work of spraying insulation on the 4th basement floor, which is a fire-prone material, is called Work A. In the work day compensation, work A is ready on October 1, work A begins on October 2 (3 workers), work A is in progress on October 3 (progress 20%, 4 people), work A is in progress on October 4 (progress) 50%, 5 people), work A is in progress on October 5th (75%, 5 people).

The control unit 21 reads this work report, organizes when task A was started and the current progress, collects comprehensive work information in one place, and systematically stores it in the work information database 24.

In a situation where a work log describes many tasks by date in a list format, information about specific tasks is extracted and collected in one place to create information about when the work starts and how it progresses.

The safety information database 25 stores risk assessment information analyzed by the control unit 21. For example, the control unit 21 determines from the work information database 24 that work A is spraying insulation on the ceiling of the fourth basement floor at the current evaluation time and that 75% of the total area has been sprayed. And the control unit 21 reads from the safety standard database 22 whether there are preceding and succeeding operation conditions. As a follow-up work condition, the refractory material application work (task B) must begin within 2 days from the date work A begins.

Alternatively, if the difference in process rates between Task A and Task B exceeds 30%, the fire risk is judged to be medium, and if it exceeds 60%, the fire risk is judged to be very high. In addition, it is determined whether there is electric welding or gas welding work on the same floor or room, and if so, the risk of fire is assessed as high. The results analyzed as above are stored in the safety information database 25.

Figure 3 shows the additional functional configuration of the safety standard database 22 according to an embodiment of the present invention.

Referring to FIG. 3, the work classification system (221), work list (222), safety standards (223), and safety measures and action methods (224) information of the safety standard database 22 according to this embodiment are stored.

The work classification system (221) is a Work Breakdown Structure (WBS) that classifies temporary work, earthwork, building work, electrical work, equipment work, and others into large work types and medium work and small work types. This work breakdown system has a code and a name, and has been created and used in the industry. However, depending on the construction in question, some items may be missing or added. Hotel construction, office construction, apartment construction, factories, etc. may have different construction types in the work classification system. The work breakdown system (221) is similar to the cost breakdown structure (CBS), but is a system for classifying construction work.

The work list 222 is a list in which work is divided by floor, room, and line based on the work classification system 221. Since RC construction is carried out on a floor-by-floor basis, it is divided into zones for each floor, such as the 5th floor underground and the 4th floor underground to the 50th floor above ground, according to the reinforced concrete construction (303) classification system.

Additionally, the task list consists of detailed tasks (Tasks) at the bottom. The 10th floor RC construction consists of pillar reinforcement, column formwork, slab formwork, slab reinforcement concrete, and electrical equipment work.

The safety standard 223 stores the safety standards of a specific task. It stores the safety standards of the work itself and the standards for preceding work, succeeding work, and spatial work up, down, left, and right.

Safety measures and action methods (224) stores information such as how to take action when the risk of a specific work is assessed, related regulations, quantitative figures, and cases from other sites. This information is used by users to quickly and accurately develop professional solutions.

Figure 4 is a conventional work daily report format. Figure 4 is an Excel file, and the today's work details (231) column describes the work details, and the tomorrow's work details (232) column describes the work to be done tomorrow. Since work usually lasts several days, I write today's work, copy it, paste it into the next day's work, and then make some modifications.

Work logs are prepared for each partner company, and for example, many partners participate in waterproofing work, painting work, scaffolding installation work, elevator installation, and fire piping work. When using PMIS using the Internet, the work details are described in the same way in today's work details (231) and tomorrow's work details (232) columns.

The number of people and progress rate can be written in parentheses after the task name. In this case, the work information for the relevant task can be clearly identified.

Figure 5 is a flowchart showing the safety information work process between a construction company and a partner company for generating and providing safety information using a work log according to each embodiment of the present invention.

First, referring to FIG. 5 according to one embodiment, the construction company and the partner company create safety standards for specific work (S10).

For example, safety standards and rules for septic tank cleaning include measuring oxygen and harmful gas concentrations, performing ventilation, and wearing a respirator or oxygen mask.

In the case of electrical equipment, the order of work is established and a condition is set that subsequent work should not be started if the preceding work is not completed or the current status is certain. In the case of electrical room construction, the standard is that no work can be performed while electricity is turned on.

In the case of construction, the condition is that work cannot begin unless safety facilities are identified.

Once the safety standards are created, they are systematically stored in the safety standards database (22) (S20). Here, the system can create a work breakdown system (Work Breakdown System) suited to the characteristics of the on-site construction, or use the conventional civil engineering, construction, and electrical equipment construction code.

In order to create work reports more quickly and accurately, it includes a method of unifying task names, creating a list in advance, and then selecting and entering them. For example, in the case of waterproofing work, you can know the floor and room (toilet, etc.) that need to be worked on, so if you create a work list in advance and then select it when entering the work log, the work name and work location are automatically entered and standardized.

Now, when construction begins, the partner company writes a work report (S30). For example, in facility construction, when the vertical piping of equipment in the machine room on the 6th basement floor begins, the work details are written in the work report as today's work and the scheduled work for the next day is also described. It may also include matters related to personnel or equipment safety.

Since work diaries are well known and have been used for a long time, detailed explanation will be omitted.

On the other hand, among many partners, there are those that only have a small number of employees and do not have temporary offices or PCs. In this case, the work details can be described using a smartphone and transmitted to the stable information server 20. When using a smartphone, you can quickly and accurately enter a task name by selecting the task list created in the standard setting step (S10~S20) above.

Once the partner companies' work logs are completed, work information is created and stored (S40). Work information is generated in a time series regarding the tasks performed by partners. For example, the control unit 21 reads the work report of the partner responsible for waterproofing, creates construction records by date from the start date of waterproofing work on the 4th basement floor bathroom, and systematically stores them in the work information database 24. The contents include the start date, progress rate, and number of workers for toilet construction on the 4th basement floor, and may additionally include information about building materials and work equipment.

Once the work report is created, the next step is to conduct a risk assessment (S50). The control unit 21 reads job information from the job information database 24. Additionally, safety standards related to a specific task are read from the safety standards database 22. Then compare work information and safety standards. As a result of the comparison, it is quantitatively determined that there is a risk if the safety standard is exceeded.

The judgment results are systematically stored in the safety information database 25.

For example, if there is welding work in a space where insulation spray paint is used, the control unit determines that the insulation spray paint is unsafe because it is a material that can catch fire. In addition, by comparing the start date or progress rate of insulation spraying with the start progress rate of fireproof material application work, which is a condition for follow-up work, it is assessed that there is a risk if it deviates from the standards.

In the case of equipment, if there is a pipe pressure test for a specific line today, check whether water vapor was discharged the previous day. If the water vapor in the pipe is not discharged, it is judged that an explosion may occur during the air pressure test.

In the case of electricity, if electricity is turned on in the electrical room, the electricity must be turned off if water-related work is performed as there is a risk of electric shock. Also, determine whether there is water-related work on the upper floor of the electrical room and whether water can enter the electrical room on the lower floor in the event of a leak.

In this way, the control unit 21 measures the preparation facilities and equipment of the work itself to perform the specific work. In addition, it comprehensively determines the risks of the preceding work, subsequent work conditions, work processes, and work taking place in the upper, lower, left, and right spaces surrounding a specific work.

In addition, the control unit 21 refers to the standards set in the safety standards 22 and comprehensively evaluates the mutual influence and risk between tasks for all tasks in the field.

As a result of the judgment of the control unit 21, if the contents of the work report are missing or difficult to read, or there is no necessary information, a query is created. Accordingly, the manager of the partner company or construction company checks the contents and modifies the work log (23) or work information (24) or writes an answer to the inquiry, and the control unit (21) refers to the answer and performs the risk assessment (S50) again. Perform (S60).

Next, when the risk evaluation (S50 to S60) is completed, the control unit 21 stores the evaluation results in the safety information database 25 and notifies the terminal 10 that the evaluation has been completed (S70).

For example, the main contractor, who oversees all partner companies, can view all safety information (25). Waterproofing work partners check the risk assessment information regarding waterproofing work on their PC or smartphone.

Additionally, the control unit 21 can create countermeasure information such as action methods or procedures, laws, regulations, etc. regarding risks. Countermeasure information can be prepared and utilized in advance in the safety standard database 22.

The construction company or partner company worker checks the contents in the risk confirmation (S70) step, takes necessary safety measures, and then inputs the results of the measures into the safety information database (25).

The control unit 21 can release risks for risk assessments for which actions have been completed and modify the contents of the work log 23 and work information 24. Alternatively, the writer of the work daily report (23) can write the work daily report by reflecting the results of safety information measures when writing the work daily report for the next day.

The following shows examples of specific work at a construction site according to the present invention from Figures 5 to 13.

Figure 6 is an example of setting safety standards for specific work according to the present invention. Referring to Figure 6, this is a process of constructing polyurethane foam on the ceiling to insulate the basement floor, from the 4th basement floor to the 1st basement floor, and the partner company is ○○ Company.

First, the first column shows the safety standard items newly proposed by the present invention. The second column sets safety standards.

First of all, the first item in the first column, the work inspection items, is the safety standard that company ○○ must adhere to while constructing polyurethane foam, an insulation material. This means that equipment and temporary scaffolding for constructing polyurethane foam must be inspected.

The second is dangerous work within the same workspace, which establishes that working with other types of work within the floor and space where polyurethane foam is being constructed may be unsafe. For example, if equipment piping, welding, temporary lighting, high-speed cutter, thinner, and paint are carried out in the same space by partners with different words or meanings, a fire may occur.

This is because polyurethane foam sprayed on the ceiling is vulnerable to fire and can burn and emit toxic gas, causing a serious disaster.

The third item is a prerequisite for work, and there may be work that must be completed first before the current work can be completed. For example, if the work to be done is exterior wall masonry, external scaffolding must be installed.

The fourth item is a follow-up work condition, which sets the status of the work that follows when constructing the current work or what relationship it has with the current work. As shown, polyurethane foam is weak against fire, so after installing polyurethane foam on the ceiling, a fire-resistant coating must be sprayed on top of it as a follow-up process to prevent fire.

However, even if the polyurethane foam is fully installed on the ceiling, if the fire-resistant coating, which is a protective material, is not sprayed or is slow to follow, the risk of fire due to sparks increases. The schedule difference is a standard for how many days apart polyurethane foam and fire-resistant covering should be carried out.

For 1 to 2 days, the area where the polyurethane foam is sprayed is not large, so damage in the event of a fire is limited. However, if there is a difference of more than 3 days or the two process rates differ by more than 40%, the area of the fireproof coating increases when the polyurethane foam is exposed. Fire risk and damage increase.

Since the above-mentioned schedule difference and progress rate difference are newly proposed according to the present invention, it is desirable for construction officials to determine the standards by considering the construction space and area to be sprayed.

The fifth item is dangerous work in the space above, below, left, and right, and it selects and describes the type of work that becomes a dangerous situation when construction is performed next to the upper or lower floor with respect to the current work. For example, falling accidents due to simultaneous work up and down, or electric shock due to high-voltage electricity may occur if water enters the electrical room on the lower floor because work is performed that may cause water to pour from the upper floor.

As described above, while in the past the focus was on unsafe work within the same space, the main feature of the present invention is that it emphasizes the importance of the relationship between preceding work and subsequent work. This is because most of the processes in which a specific space is completed and finishing work and electrical installation work are carried out are mutually influenced in a serial relationship rather than as individual tasks.

Safety standards utilize existing related laws and guidelines, but additionally, to prevent safety accidents, it is effective to introduce the process management concept to analyze the influence between tasks in a time series and limit the scope of that influence to set safety standards. is judged to be very large.

In general, the status of all work carried out on site is checked daily at the lowest level possible through work reports, and the risk of safety accidents increases if the above safety management standards are exceeded. Knowing the problem is of utmost importance, and solutions can be established and acted upon with current technology.

As the next step, Figures 7 to 9 show the work report creation step.

*First, Figure 7 is an example showing a work report prepared by a partner performing insulation work according to the present invention. It is similar to a conventional work daily report and can be written quickly and easily using the following Hangul, MS Word, Excel, PMIS, on the web, and using a smartphone.

The previous day's work section briefly describes what work was done on what floor and in what area, by how many people, and to what extent.

Today's work column indicates that, continuing yesterday, work on spraying polyurea foam on the ceiling was carried out in the machine room on the 4th basement floor and Zone A on the 1st basement floor, and that work began today on Zone B on the 1st basement floor.

A partner company only needs to briefly describe where and what work their company's workers do.

Figure 8 is an example of a work report prepared by a partner performing fire-resistant coating work according to the present invention. When the polyurea foam spraying work of Figure 7 progresses, the work of spraying the fire-resistant coating of Figure 8 follows on top of it. Figure 7 is the current work and Figure 8 is the subsequent work. As the distance between Figures 7 and 8 increases, the risk of fire increases.

Figure 9 is an example showing a work report prepared by a partner performing fire extinguishing piping work according to the present invention. It describes work being carried out in the machine room on the 4th basement floor.

Above, among the work logs written by many partner companies, examples of work logs related to the machine room on the 4th basement floor are shown in Figures 7, 8, and 9. Partner companies just need to describe the work their company is doing as shown in Figures 7 to 9.

Since the work log describes the details of daily work, it is not limited to the above format, and risk assessment notes, notepads, and other construction materials can also be used as a work log if they include the job name, location, and work date information.

If each partner prepares a separate work report, the number of pages will be large, so from the contractor's perspective, it is necessary to collect them in one place. Figure 10 is an example of each work report collected in one place and printed on October 1, 2018. The work logs created in Figures 7, 8, and 9 are integrated and displayed. The control unit 21 performs these tasks.

During the finishing construction period, in the case of large-scale construction, dozens or more partners are dispatched to prepare the work, so the number of pages in Figure 10 becomes large and the content becomes extensive.

Figure 11 is an example of the contents of the work report prepared by a partner performing insulation work according to the present invention organized by date for specific work.

Spraying polyurea foam to insulate the ceiling of the machine room on the 4th basement floor began on September 27th and is currently in the 5th day of work. The progress rate is 80% and is scheduled to be completed tomorrow. It can be seen that 3 workers are working as a team.

Figure 12 is an example of the contents of the work report prepared by a partner performing fire-resistant coating work according to the present invention organized by date for specific work.

In order to protect the polyurea foam spray coating shown in Figure 11 installed on the ceiling of the machine room on the 4th basement floor, fire-resistant coating is being constructed as a follow-up work. Work preparations were made on September 30th and work began today, October 1st.

Figures 11 and 12 are automatically created from the work logs of Figures 7 and 8. Figures 7 and 8 have the disadvantage of requiring daily viewing of the work in the machine room on the 4th basement floor to understand the flow. Looking at Figure 11, you can see the work in Figure 7 by date without looking at it every day.

Figures 11 and 12 are used to determine whether the safety standard of Figure 6 is exceeded by calculating the start date difference or progress rate difference between the preceding and succeeding tasks.

Figure 13 is an example showing the results of risk assessment from Figures 11 and 12. In Figure 11, the polyurea foam spraying work started on September 27th and is nearing completion, but the fireproof coating construction in Figure 12 for fire prevention started late on October 1st, and the polyurea foam is exposed to fire.

The control unit 21 determines whether the schedule difference and process rate difference between FIGS. 11 and 12 exceed the follow-up operation conditions of FIG. 6 and displays the result. According to the evaluation, as of October 1st in the machine room on the 4th basement floor, 80% of polyurea foam was sprayed on the ceiling, and on the same indoor floor, pipes were cut with a high-speed cutter and pipes were cut for the installation of facility sprinklers and fire extinguishing pipes. We are working on cleaning the connecting parts with thinner. And the fire-resistant cladding construction is about to begin.

If you cut the pipe with a cutter, sparks will fly, if it catches on the thinner, it will catch fire, and if it transfers to the ceiling, most of the polyurea foam will catch fire. This is because the follow-up process, spraying fire-resistant coating, follows late.

Currently, the risk of fire is assessed to be very high in the machine room as several types of workers work there.

In the past, serious disasters caused by smoke from polyurea foam catching fire in the basement have been reported on the news several times.

The cause of the accident is generally focused on the management of the cutter and the spark of the thinner, but looking at the example of the assumption according to the present invention, the cause of the accident is not only other work in the space, but also additional up and down work, preceding processes, and subsequent work. When analyzing the state of the process three-dimensionally in a time series, the fire-resistant coating, which is a follow-up process, was started late and was followed late, and the cause was that the polyurea foam was not protected from flames through the fire-resistant coating. If the delay in starting the fire-resistant coating had been pointed out in advance through the application of the present invention, the fire would not have occurred or the damage would not have been significant through the measures taken.

As described above, only one example is given in this embodiment, but according to the present invention, various risks ranging from major disasters exceeding the safety standards systematically set in advance to minor disasters are avoided for work in all spaces conducted in construction and industrial sites. By making a quick and accurate assessment, necessary measures can be taken and as a result, safety accidents will not occur.
