Method and device for generating safety information using daily work reports

Abstract

The present invention relates to a system for preventing safety disasters during construction and industrial construction sites. More specifically, the system involves analyzing the content of a daily work report for each type of work and generating process progress information. The system can then calculate disaster risks by identifying the preparedness status of previous and subsequent work, thereby enabling preventive measures to be taken. The system includes a first step of defining safety matters for each work and establishing safety standards in relation to previous and subsequent work; a second step of each partner company preparing its own work report as it performs work during the construction process; a third step of generating work information by analyzing the content of the work report and generating work performance information; a step of evaluating the risk of each work by determining whether the work information from the second or third step exceeds the safety standard from the first step; and a fifth step of determining, based on the comparison results of the above steps, whether there is a risk if the safety standard is exceeded.

Description

Technical Field

[0001] The present invention relates to a method for preventing safety disasters occurring during construction at construction and industrial construction sites, and more particularly to a method for enabling a control unit to take preventive measures in advance by analyzing risks when parallel work and previous work are not completed or subsequent work cannot cover all work on site by using a large amount of construction progress information from daily work reports compiled by multiple temporary civil construction electrical equipment cooperation companies. Background Art

[0002] Taking the OECD's work-related accident rate as an example, South Korea's death rates per 100,000 people were 3.0 and 7.0, respectively, twice the OECD rate (JoongAng Ilbo, August 28, 2017).

[0003] According to the Ministry of Employment and Labor's 2016 work-related accident statistics, there were 9,656 workplace accidents, representing an average of more than 10 injuries every hour. Construction accidents accounted for 29.3% of all industries, with 1,777 fatalities, representing at least one fatality every five hours.

[0004] In 2016, there were 969 fatal accidents across all industries, of which 499 occurred in the construction industry, accounting for 51.5% of all industries (Construction Economy 2017.05.25).

[0005] With the development of construction technology, the construction of high-rise buildings and high-rise apartment buildings has increased, and the number of buildings deep underground has continued to increase, along with large shopping malls and large factory complexes that spread out horizontally.

[0006] As a result, up to thousands of workers are distributed vertically and horizontally across many spaces every day, and the work of dozens or hundreds of temporary building electrical installations is complicated by each other, making it difficult for construction companies to manage the work and the expansion of safety managers is limited.

[0007] The number of objectives to manage security has become large and complex, yet maintaining existing human management methods.

[0008] For example, manpower-based safety management occurs when managers lack construction experience, are unaware of safety issues in specific spaces, misunderstand them, and dismantle or move safety facilities without authorization. There are also problems such as poor communication between previous and subsequent work types, workers entering restricted areas without their knowledge, and inadequate safety facilities.

[0009] The following are contributions from security experts.

[0010] Any safety expert knows that there is a causal relationship between the four principles of disaster. All disasters have a cause. The most unfortunate of all construction accidents is that no matter how well the injured follow safe work procedures, if the previous process creates incorrect working conditions, the disaster will occur.

[0011] Such examples occur in most construction accidents (Construction Economy 2017.05.25).

[0012] It is judged that the above existing safety management methods are unable to manage large and complex work or safety facilities, equipment and workers based on limited manpower and experience.

[0013] As documents related to safety management, there are risk assessment reports, hazard prevention plans, night work permits and daily work reports.

[0014] First, in the case of risk assessment, the process is as follows.

[0015] At the beginning of construction, when preparing the hazard prevention plan, safety management plan or construction plan, a preliminary risk assessment is carried out. Risk assessment is conducted in combination with site conditions before relevant work is carried out, and a schedule is created by dividing the work from material import to construction material export into detailed units.

[0016] When classifying unit work, identify risk factors (human factors, mechanical factors, electrical factors, material factors, work characteristics factors, work environment factors, etc.) for the work. Establish safety measures that can be taken on-site for the identified risk factors, and determine the risks, such as those reviewed by the creator, construction manager, and safety manager.

[0017] On the other hand, risk assessment reports are very important. Part of the entire work is to evaluate high-risk work, and the evaluation content is written based on the supplier's personal capabilities.

[0018] Therefore, risk assessments do not cover the entire project and there are still tasks that have not been assessed. Especially during interior renovations, many tasks are carried out simultaneously, so preparing risk assessment reports and assessment meetings requires a lot of time and effort.

[0019] On the other hand, a daily work diary is a construction plan and record written in text format by dozens or hundreds of temporary civil engineering, construction, power, and equipment companies involved in the construction. The work diary includes the work completed the previous day and the work to be completed that day, and further records the number of workers and equipment.

[0020] The purpose of creating a daily work report is to simply understand what work is being done and where in the partner company.

[0021] The work diary is used by copying text sentences describing the previous day's work, pasting them into today's work, and making corrections and additions. The advantage is that it takes less time and effort to write. It is written by the cooperating company using the on-site PMIS or word processor Excel program.

[0022] On the other hand, because the contents of the daily reports are scattered like a mosaic of tiles on a wall, it is difficult to fully grasp the overall progress.

[0023] In addition, since only one page was written for each cooperating company, it became more than dozens of pages during the sorting and internal construction, making it difficult to see the whole.

[0024] The daily work report is a brief record of the location, content and number of people working on that day by each partner company and is not written for the purpose of safety management. Summary of the Invention

[0025] Technical problems to be solved

[0026] In the prior art, risk assessment is mainly based on major tasks, while the present invention introduces the concept of comprehensive risk assessment of all tasks on site. This is because safety accidents occur not only in major tasks but also in small tasks.

[0027] In the prior art, the cause of the disaster is mainly determined by visually visible problems in a specific space, while in the present invention, in addition to the existing analysis methods, it is also necessary to comprehensively analyze the causal relationship between the previous work and the subsequent work that affects the work in a time series.

[0028] Based on existing personal experience and capabilities, we implement quantified and immediate risk assessments through objective and systematic safety standards verified in advance by multiple experts.

[0029] Technical Solution

[0030] In order to solve the above technical problems, the present invention evaluates the risks of equipment such as temporary materials required for the work of a partner company.

[0031] Defines what other dangerous concurrent work is happening in the same workspace.

[0032] By analyzing the impact of previous work and subsequent work, and conducting a comprehensive analysis in time series, we can determine what state the previous work should be in to be safe.

[0033] To determine whether a specific job is dangerous, risk assessment standards are established through objective data standards, laws and regulations, cases, expert opinions, etc.

[0034] These include safety facility standards (height, strength, size, installation time, retention period, and dismantling time), working condition standards (temperature, humidity, wind, toxic gases, lighting, electric shock, pressure, and other working conditions for temporary electrical equipment during construction), progress differences from previous work (conditions under which previous work must be completed), and progress differences from subsequent work (conditions that subsequent work must follow).

[0035] These data are categorized by job type and job type and made into a DB.

[0036] The method of collecting work information is to use the existing work daily reports without additional effort or system manpower.

[0037] The daily work report is a record of the daily work of all cooperating companies. Therefore, it contains almost all the work on site and is written by public officials. Therefore, it is accurate, reliable and rich in content.

[0038] To provide a more comprehensive understanding of construction progress, we aggregated specific work details scattered by date into one place and created them by date. This information includes work location, work content, number of workers, progress rate, etc.

[0039] Risk assessment is carried out by comprehensively judging the degree of danger of the work environment based on the content of the daily work analysis and the setting stage of the safety standards by the control unit.

[0040] Beneficial effects

[0041] According to the present invention, the following effects can be expected.

[0042] In the prior art, risk assessments were only performed on high-risk or major work, but according to the present invention, risk assessments can be performed on almost all work performed on construction sites and industrial sites. A comprehensive survey of all work can be conducted.

[0043] In addition to existing safety management activities, there is no need to invest additional manpower, energy, time, or systems. Simply create a daily report on existing work to analyze risks systematically and immediately.

[0044] Existing risk assessments are highly subjective, with the content varying depending on the evaluator's individual abilities. However, according to the present invention, risk assessments are refined by preparing objective, systematic safety criteria such as expert group opinions, laws and regulations, safety standards, and examples in advance.

[0045] Existing work daily reports are used to grasp the working status or leave records. However, according to the present invention, the status information on the scene can be fully grasped by using the lowest level work content and personnel and equipment information in the work daily reports.

[0046] In the prior art, the start and completion status of some major tasks are mainly managed. However, according to the present invention, construction records can be created for all tasks on site by date.

[0047] In the prior art, work daily reports are compiled by date. In order to understand the preparation, start, and end of a specific task, it is necessary to read and organize the content of the specific task by date. However, due to the large amount of content, it consumes a lot of manpower, time, and energy, making it difficult to fully organize the content.

[0048] According to the present invention, since the control unit reads and synthesizes the work contents by date, the work information can be quickly and accurately synthesized in time series.

[0049] You can see how many people work on a specific floor, location, or space, and how dangerous that space is.

[0050] Therefore, dangerous and heavily staffed spaces can be identified sequentially, allowing disasters to be minimized through centralized management.

[0051] It is difficult to analyze the previous work or subsequent work of performing dangerous specific work. In the case of analysis, manual analysis by analysts also takes a lot of time and effort, and the content is also subjective.

[0052] According to the present invention, it is possible to accurately understand how previous or subsequent work related to a specific task will affect the status of the current task. Therefore, it is possible to systematically analyze not only the problems of the specific task itself, but also the relationship with the external environment surrounding the specific task (different types of work, previous and subsequent work, upper and lower, left and right work).

[0053] This invention thoroughly investigates ongoing work at the site. It integrates scattered, fragmented information to provide comprehensive daily work information. Because the history of all work is known, comprehensive assessments can be made. By comparing against objective standards, the risk level of the current work status can be quantitatively analyzed.

[0054] By identifying the status of previous and subsequent work related to the work, a comprehensive assessment of the impact on the current work can be made. These processes can quickly and accurately collect, organize, synthesize, and evaluate in real time based on pre-written procedures and standards to manage the risks of all operations on site.

[0055] Therefore, problems that lead to safety incidents and disasters can be continuously eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Hereinafter, an apparatus and method for generating safety information using a daily work report according to the present invention will be described in detail.

[0070] Figure 1 1 is a block diagram illustrating a configuration of a security information server 20 and a terminal 10 for generating and providing security information using a work daily report according to an embodiment of the present invention.

[0071] refer to Figure 1 According to the embodiment, the security information server 20 using the work diary is responsible for receiving and determining the security information and providing it to the terminal 10. The terminal 10 is responsible for inputting and querying the work diary or security information.

[0072] Figure 2 is a block diagram of a safety information generating apparatus using a work daily report according to the present invention.

[0073] refer to Figure 2 The functional configuration of the security information server 20 according to this embodiment includes a control unit 21 , a security standard database 22 , a daily work database 23 , a work information database 24 , and a security information database 25 .

[0074] The control unit 21 stores safety-related standards in a safety standards database 22 and daily work reports in a daily work report database 23. It then reads work information from the daily work report database 23, generates work details for each day of a specific job, and stores them in a work information database 24. After analyzing risks, the results are stored in a safety information database 25. Furthermore, the control unit is responsible for transmitting the database contents to the terminal 10 upon user request.

[0075] The control unit 21 can display the risk level of each step, level and grade of work that exceeds safety standards. The scale and impact of disasters expected on site can be ranked and displayed by order of magnitude.

[0076] If the contents of a work report do not match or there is a risk of a safety disaster, the control unit 21 can query the creator of the work report. The control unit 21 can display the work of multiple companies to be constructed in a specific space on a drawing plane or in 3D space, using text and icons for each company's work. The control unit 21 reads and displays countermeasures from a countermeasure database for work that exceeds safety standards.

[0077] The safety standards database 22 stores safety standards for specific jobs. For example, if the job title is cleaning a septic tank, the safety standards and regulations include measuring the concentration of oxygen and harmful gases, performing ventilation, and wearing an air respirator or an oxygen mask.

[0078] When the concentration of hydrogen sulfide reaches 20-30 ppm, olfactory nerve cells will become fatigued. When it exceeds 700 ppm, the oxidative capacity in the blood is exceeded, attacking nerve cells and causing neurotoxic effects.

[0079] The safety standards database 22 also stores conditions for previous or subsequent operations of a specific work. For example, when working on a specific piece of equipment, whether a valve was closed during the previous operation is important. If the valve is not temporarily opened and closed, an explosion or pipe burst may occur during the subsequent operation.

[0080] As a condition for subsequent work, if a specific work involves spraying insulation with a material that presents a high fire risk, a fire-resistant coating must be applied around the paint. If this follow-up work is not performed or is performed too late, the insulation coating will be significantly exposed, increasing the fire risk. A schedule or process rate difference should be established between the current spray insulation work and the subsequent spray refractory work. Since this difference can vary depending on the number of floors, area, and other factors, it is best to consider the site's specific characteristics when setting it up.

[0081] A safety standards database22 was created for each type of work. Each work category included civil, construction, electrical, equipment, environmental, and plant, and was assigned a name and code based on the work breakdown structure. For example, an excavator's name was "excavator" and its code was 110. Reinforced concrete construction was designated 301, with phases such as lower-level rebar construction 301-01, formwork 301-02, and concrete construction 301-03.

[0082] Job titles can be written and stored in various languages ​​including Korean, English, Japanese, Chinese, Hindi, and Spanish.

[0083] Furthermore, safety standards are stored on a server at the construction company headquarters. Safety standards can be downloaded from the safety standards database 22 server at the construction company headquarters to servers at various sites for use. Construction company administrators or administrators of specialized construction companies can modify and apply safety standards based on site characteristics, or create and apply new standards.

[0084] The safety standards database 22 may also include objective standards of codes and laws, and may include disaster and accident cases. Past safety disasters are categorized by including information such as construction type and construction type (construction, power, etc.) to match them to on-site work.

[0085] After being stored on the server, the safety standards database 22 can be shared by a specific construction company and provided to national agencies, research institutions, other construction companies, and even other countries.

[0086] The daily work report database 23 stores daily work reports from partner companies for various types of work, such as temporary civil engineering, construction, and electrical equipment. These reports are compiled into Excel files, Korean documents, Word documents, or PMIS websites. Work locations can be selected and entered from floor plans, BIM 3D models, or location lists. The daily work report allows users to enter work hours (morning, afternoon), change, cancel, start, and complete work. Whenever work content changes, the control unit 21 re-analyzes the safety impact of the changes. Daily work reports are entered using an application on a PC or smartphone.

[0087] In the work information database 24, the control unit 21 reads the work details of specific jobs from the work daily database 23 by date and stores the information in chronological order. For example, the work of spraying insulation material, a flammable material, on the fourth underground floor is called work A. Suppose the work daily records that work A was prepared on October 1st, started on October 2nd (with three workers), completed on October 3rd (with 20% completion, involving four workers), completed on October 4th (with 50% completion, involving 50 workers), and completed on October 5th (with 75% completion, involving five workers).

[0088] The control unit 21 reads the daily work report, organizes the start time and current progress of work A, collects and generates comprehensive work information in one place, and then systematically stores it in the work information database 24.

[0089] In a state where a work diary describes multiple tasks by date in a list format, information about a specific task is extracted and centralized in one location to generate the start time and method of the task.

[0090] Safety information database 25 stores risk assessment information analyzed by control unit 21. For example, control unit 21 determines from work information database 24 that work A involves spraying insulation material on the ceiling of the fourth underground floor at the current assessment time, covering 75% of the total spray area. Control unit 21 also reads from safety standards database 22 whether a previous work condition or a subsequent work condition exists. As a subsequent work condition, the refractory coating work (work B) must begin within two days of the start date of work A.

[0091] Alternatively, if the difference between the process rates of work A and work B exceeds 30%, the fire risk is determined to be moderate, and if it exceeds 60%, the fire risk is determined to be very high. Furthermore, if it is determined whether electric welding or gas welding is being performed on the same floor or in the same room, and if so, the fire risk is assessed as high. The results of these analyses are stored in the safety information database 25.

[0092] Figure 3An additional functional configuration of the safety standard database 22 according to an embodiment of the present invention is shown.

[0093] Reference Figure 3 , storing information of a work classification system 221 , a work list 222 , a safety standard 223 , a safety measure, and a measure method 224 of the safety standard database 22 according to this embodiment.

[0094] Work Classification System 221 categorizes temporary works, civil engineering, architectural works, electrical works, and facility works as large projects, and the Work Breakdown Structure (WBS) as medium and small projects. This work classification system has codes and names, and is established and used in existing industries. However, some items may be missing or added depending on the project. Different types of work classification systems exist for hotel construction, office building construction, apartment construction, and factory construction.

[0095] The work list 222 is a list that divides the work into floors, rooms, and lines based on the work classification system 221. Since RC construction is carried out floor by floor, the reinforced concrete construction 303 classification system is divided by floor, such as 5 underground floors, 4 underground floors to 50 floors above ground, etc.

[0096] In addition, the work list consists of detailed work (Tasks) at the bottom. The 10th floor RC construction includes column reinforcement, column frame, slab formwork, reinforced concrete, and electrical installation work.

[0097] The safety standard 223 stores the safety standards of a specific job, including the safety standards of the job itself, as well as the standards of the front, back, up, down, left, and right space jobs.

[0098] Safety measures and measures 224 store information such as how to take measures when assessing the risks of a specific work, relevant regulations, quantity figures, and other field cases. Users use this information to quickly and accurately create professional solutions.

[0099] Figure 4 For existing workday reports. Figure 4 It is an Excel file. The work to be done today is described in column 231 of the current day's work content, and tomorrow's work is described in column 232 of the next day's work content. Since this work usually takes several days, after writing the work for the day, it is copied and pasted into the work for the next day, and then some modifications are made.

[0100] Daily work reports are compiled by each contractor. For example, waterproofing work, painting work, scaffolding installation work, elevator installation work, fire extinguishing pipe work, etc. involve multiple contractors. When using PMIS via the Internet, the work content is described in the same manner in column 231 of the current day's work content and column 232 of the next day's work content.

[0101] The number of people and progress can be indicated in brackets after the job title. In this case, the work information of the corresponding job can be clearly grasped.

[0102] Figure 5 Flowchart of a safety information working process between a construction company and a partner company using a daily work report to generate and provide safety information according to the present invention.

[0103] First, referring to the embodiment Figure 5 , construction companies and cooperative companies create specific work-related safety standards S10.

[0104] For example, safety standards and regulations for cleaning septic tanks include measuring oxygen and harmful gas concentrations, performing ventilation, and wearing air respirators or oxygen masks.

[0105] In the case of electrical installation, the work sequence is determined, and the conditions are set that subsequent work cannot be started until the previous work is completed or regardless of the current status. When constructing an electrical room, it is a standard that no work can be carried out while the power is on.

[0106] In the case of construction, work cannot begin without ensuring safety features. When safety standards are compiled, they are systematically stored in the safety standards database 22 ( S20 ). At this point, the system can create a work breakdown system tailored to the specific construction site or utilize existing civil engineering, architectural, and electrical installation codes.

[0107] To create a work diary more quickly and accurately, it's important to standardize the job names, prepare a list in advance, and then select a method for inputting them. For example, in the case of waterproofing, you know the floors and rooms (such as restrooms) to be worked on. Therefore, if you prepare a list of jobs in advance and select it when entering the work diary, the job names and locations will automatically be standardized.

[0108] When construction begins, the contractor compiles a daily work report (S30). For example, when laying vertical piping for equipment in a six-story underground machine room begins during facility construction, the work details are listed as part of the day's work and include a description of the next day's scheduled work. Issues related to personnel and equipment safety may also be included.

[0109] Since the work is done daily, detailed description is omitted.

[0110] On the other hand, some of the many partner companies lack temporary offices or personal computers due to limited staffing. In such cases, the job description can be sent to the secure information server 20 by describing it using a smartphone. Using a smartphone, the job title can be quickly and accurately entered by selecting the job list created in the standard setup steps S10 to S20.

[0111] When a partner's daily work report is completed, work information ( S40 ) is created and stored. Work information is created chronologically for each work performed by the partner company. For example, the control unit 21 reads the daily work report of the partner company responsible for waterproofing, creates a construction record by date starting with the start date of waterproofing work for the fourth-floor basement bathroom, and systematically stores it in the work information database 24. This record includes the number of workers on the start date of construction of the fourth-floor basement bathroom, as well as information on construction materials and equipment.

[0112] After preparing the daily work report, the next step, risk assessment ( S50 ), is performed. Control unit 21 retrieves work information from work information database 24 . Furthermore, it retrieves safety standards associated with the specific work from safety standards database 22 . The control unit then compares the work information with the safety standards. If the comparison result exceeds the safety standard, a quantitative risk assessment is performed.

[0113] The judgment results are systematically stored in the security information database 25 .

[0114] For example, if welding is being performed in a space where insulation spraying is being performed, the control unit determines that the insulation spraying is an unsafe material that could cause a fire. Furthermore, by comparing the start date or progress of the insulation spraying with the progress of the refractory material application, which is a condition for subsequent work, the control unit assesses whether there is a risk of deviation from the standard.

[0115] Regarding equipment, if a specific line is being pressure-tested on the same day, check to see if any water vapor has been released the day before. If the water vapor in the pipe has not been released, it is considered a possibility of explosion during the pressure test.

[0116] If there is electricity in the power room, there is a risk of electric shock when entering the power room for wading through water, so the power must be turned off. In addition, determine whether there is any wading through water on the upper level of the power room. If there is a water leak, determine whether water can enter the power room below.

[0117] In this way, the control unit 21 measures the preparation facilities and equipment for the work itself to perform corresponding operations for the specific work. In addition, the control unit 21 comprehensively judges the work risks occurring around the previous work, subsequent work conditions, work process, and the upper, lower, left, and right spaces of the specific work.

[0118] In addition, the control unit 21 comprehensively evaluates the mutual influence and risks between operations of all operations on site with reference to the standards set in the safety standards 22 .

[0119] As a result of the determination by the control unit 21, if the work diary 23 or the work information 24 is omitted or difficult to read and does not contain necessary information, the content of the consultation is written. If the administrator of the cooperative company or the construction company checks the content and corrects the work diary 23 or the work information 24 or creates an answer to the consultation content, the control unit 21 refers to the answer and re-executes step S60 of the risk assessment S50.

[0120] Next, when the risk evaluation S50 to S60 is completed, the control unit 21 stores the evaluation result in the security information database 25 and notifies the terminal 10 of the completion of the evaluation S70.

[0121] For example, a general contractor who oversees all partner companies can view all safety information. 25 A waterproofing contractor can query the risk assessment of a waterproofing project using a PC or smartphone.

[0122] In addition, the control unit 21 may create countermeasure information such as risk-related measures or procedure manuals, laws, regulations, etc. The countermeasure information may be created in advance in the safety standard database 22 and used.

[0123] After confirming the content of the risk in step S70 , the staff of the construction company or the partner company takes necessary safety measures and inputs the results of the measures into the safety information database 25 .

[0124] The control unit 21 can publish the risk assessment for the completed measures and modify the content of the work diary 23 and the work information 24. Alternatively, the staff who prepares the work diary 23 can also reflect the safety information measures results when preparing the work diary the next day.

[0125] Modes for Carrying Out the Invention

[0126] Below from Figures 5 to 13 An embodiment of a specific operation of a construction site according to the present invention is shown.

[0127] Figure 6 is an example of setting safety standards for a specific job according to the present invention. Figure 6 , is the process of installing polyurethane foam on the ceiling of the basement for insulation, from the 4th underground floor to the 1st underground floor, and the cooperative company is ○○.

[0128] First, the first column shows the safety standard items newly proposed by the present invention. In the second column, the safety standards are established.

[0129] First, the first item in the first column, the staff self-inspection item, is the safety standards that ○○ Company must comply with during the construction of polyurethane foam plastics as an insulation material. The equipment and temporary equipment used in the polyurethane foam construction process need to be inspected.

[0130] The second is that performing hazardous work in the same workspace as other types of work in the same layer and space as installing polyurethane foam may be unsafe. For example, words or meanings such as plumbing, welding, temporary lighting, high-speed cutting machines, thinners, or paints may cause fires when performed in the same space by different collaborating companies.

[0131] Polyurethane foam sprayed on the ceiling has weak fire resistance, can burn, and can emit toxic gases that can cause serious disasters.

[0132] As a predecessor to the third item, some work may have to be built before the current work can be constructed. For example, if the current work is to build an exterior wall, then external scaffolding must be installed.

[0133] The fourth item is the conditions for subsequent work. This establishes the status of subsequent work within the current work, or its relationship to the current work. Because polyurethane foam has weak fire resistance, after installing it on the ceiling, it needs to be sprayed with fire-retardant coating as a follow-up work to prevent fires.

[0134] However, even if polyurethane foam is installed on the ceiling, if fire retardant coating is not sprayed as a protective material or the follow-up speed is slow, the risk of fire caused by flames will increase. The time difference is the standard of how many days should be different between polyurethane foam and fire retardant coating.

[0135] If the time difference is 1 to 2 days, the area of ​​the polyurethane foam spraying is not large, so even if a fire occurs, the damage is limited. However, if there is a difference of 3 days or more, or the two processing rates differ by more than 40%, when the polyurethane foam is exposed, the area of ​​the fireproof coating increases, increasing the risk of fire and damage.

[0136] Since the above-mentioned schedule difference and progress difference are newly proposed according to the present invention, it is preferred that the standards be determined by the personnel involved in the construction in consideration of the construction space and the spraying area.

[0137] The fifth item is "Hazardous Work in Spaces Above, Below, Left, or Right." For the current work, select and describe the type of work that poses a risk when working near the upper or lower floors. For example, vertical movement could result in a fall hazard, or work on the upper floor could cause water leakage, potentially leading to electric shock from high voltage if water enters the electrical room below.

[0138] As mentioned above, while the prior art focuses on unsafe work within the same space, the present invention emphasizes the importance of the relationship between previous and subsequent work. In most cases, the process of completing a specific space and performing renovation work and electrical installation work is a continuous relationship rather than a separate task, and in most cases, they affect each other.

[0139] Safety standards utilize relevant existing laws and guidelines, but introduce the concept of process management to prevent additional safety incidents, analyze the impact between work in a time series, and limit the scope of the impact, setting it as a safety standard is considered to be very effective.

[0140] In summary, through daily work, at the lowest possible level, we must understand the status of all on-site work. Deviations from the above safety management standards increase the risk of safety incidents. Understanding the problem is crucial, allowing us to develop solutions and take action using current technology.

[0141] As a next step, Figures 7 to 9 Shows the steps for creating a work diary.

[0142] first, Figure 7 This example shows a daily work report prepared by a partner company that performs insulation work according to the present invention. Similar to existing daily work reports, this report can be quickly and easily created using the following Hangul, MS Word, Excel, PMIS, website, and smartphone.

[0143] In the all-day work column, a brief description is given of how many people did what work, in which area, on which floor, and to what extent the work was done.

[0144] The work column for the day showed that following yesterday, the ceiling spraying of polyurea foam was underway in the underground 4th floor machine room and underground 1st floor area A, and work on underground 1st floor area B started on the same day.

[0145] The partner company only needs to provide a brief description of where the employees are and what they are doing.

[0146] Figure 8 is an example showing a daily work report prepared by a partner company that performs refractory coating work according to the present invention. Figure 7 When spraying polyurea foam, spray Figure 8 Operation of refractory coating. Figure 7 It's the current job. Figure 8 This is the follow-up work. Figure 7 and Figure 8 As the distance between them increases, the risk of fire increases.

[0147] Figure 9 This is an example showing a daily work report prepared by a partner company working on a fire extinguishing pipe according to the present invention, showing work in progress in a machine room on the fourth underground floor.

[0148] As mentioned above, among the daily work reports written by the above-mentioned cooperative companies, the daily work reports related to the underground 4th floor computer room are taken as an example. Figure 7 、 8、9. The cooperative companies are as follows Figures 7 to 9 The only thing shown needs to be a description of the work being done.

[0149] Since the work diary describes the daily work content, it is not limited to the above form. If the risk assessment report, notepad and other construction materials also include information about the work name and location and work date, they can be used as the work diary.

[0150] If each partnership company prepares a daily work report, the number of pages will be very large, so it is necessary to have the original contracting company collect them in one place. Figure 10 This example collects and outputs all the daily workday reports from October 1, 2018, in one place. Figure 7 、 Figure 8 、 Figure 9 Display the work daily report. This operation is performed by the control unit 21.

[0151] In the case of a large-scale company during the renovation period, there were more than a dozen partners working and writing, so Figure 10 The number of pages is large and the content is huge.

[0152] Figure 11 This is an example in which the contents of a daily work report prepared by a partner company that performs insulation work according to the present invention are arranged by date with respect to a specific work.

[0153] The thermal insulation polyurea foam spraying of the ceiling of the underground 4th floor machine room started on September 27. As of today, the 5th day, the progress is 80% and it is scheduled to be completed tomorrow. A team of 3 people can be seen at work.

[0154] Figure 12 This is an example in which the contents of a daily work report prepared by a partner company that performs refractory coating work according to the present invention are arranged by date of a specific work.

[0155] In order to protect the Figure 11 Polyurea foam spray is being applied as a follow-up to the fire retardant coating. Preparations began on September 30th and work began on October 1st.

[0156] Figure 11 and Figure 12 is based on Figure 7 and Figure 8 The daily work report is automatically created. Figure 7 and Figure 8 As shown, the disadvantage is that you can only understand the workflow of the underground 4-story computer room by reading the content every day. Figure 11 You don't have to watch it every day Figure 7 The jobs can also be known by date.

[0157] Figure 11 and Figure 12Used to determine if exceeded by calculating the difference in start dates or processing rates between the preceding and succeeding jobs Figure 6 safety standards.

[0158] Figure 13 Yes Display Figure 11 and Figure 12 Example of risk assessment results. Figure 11 The spraying of polyurea foam started on September 27 and is currently being completed. Figure 12 The fireproof coating construction started on the evening of October 1, and the polyurea foam was exposed to fire hazards. Control Unit 21 determined Figure 11 and Figure 12 Is the difference between the schedule difference and the progress rate greater than Figure 6 The subsequent work conditions will be evaluated and the results will be displayed. Based on the evaluation results, as of October 1st, polyurea foam was sprayed on 80% of the ceiling in the underground fourth-floor machine room. Pipes were cut using a high-speed cutting machine on the interior floor, sprinkler pipes were installed, and pipe joints were cleaned with a thinner. Fire retardant coating application is about to begin.

[0159] If the pipe is cut with a cutter, sparks will fly and if they stick to the thinner, they will catch fire. If they move to the ceiling, most of the polyurea foam will catch fire. This is because the fire retardant coating spraying work is carried out later as a follow-up.

[0160] Currently, the plant room is assessed as having a very high fire risk due to the many types of work performed there.

[0161] In the past, polyurea foam fires in basements and the serious disasters caused by thick smoke have been reported in the news many times.

[0162] While the cause of the accident is generally focused on the cutting machine's operation and the thinner flame, a hypothetical example based on the present invention allows for a three-dimensional, time-series analysis of the cause, looking not only at other work in the space but also at the work above, below, and in front of and behind. The cause is that the fire-retardant coating applied at the rear was delayed, failing to protect the polyurea foam from the flames. If the present invention had been used to identify the delay in applying the fire-retardant coating, the fire could have been prevented or the damage minimized.

[0163] Industrial Application Possibilities

[0164] The present invention can be applied to various types of work (civil engineering, construction, electricity, equipment, environment, and factory) performed in all spaces within construction and various industrial sites (shipbuilding, automotive, etc.). When professional construction companies use PCs or smartphones to input their work, the control unit according to the present invention comprehensively grasps the work environment, the priority relationship between tasks, safety standards, etc. in real time to implement high-risk operations, which can be used as a method to reduce safety accidents through analysis and notification.
