Description

Method for Safety Information Generation by Reading Schedule Bar Charts in Construction and Industrial Project}

The present invention is intended to prevent safety accidents that occur during construction at construction and industrial construction sites, and more specifically, by using construction progress information of a schedule table prepared by multiple partners of temporary civil engineering, construction, and electrical equipment work, It is about taking action in advance by analyzing and evaluating the risk in case of not being completed or follow-up work is not followed, in case of dangerous work in the same space.

OECD industrial accidents have 3.0 deaths per 100,000 people, and Korea has 7.0, which is twice the level of the OECD (JoongAng Ilbo 2017.08.28).

According to the 2016 industrial accident occurrence 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 deaths was 1,777, with more than one death occurring every 5 hours, and the number of construction deaths was 31.2% compared to all industries.

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

Efforts such as worker safety training, implementation of a risk assessment system prior to commencement of work, improvement of related systems, expansion of facility and human investment, and strengthening of penalty points and penalties are ongoing to prevent accidents that occur during construction at construction sites.

Despite these efforts, the reason why disasters have not decreased is judged to be due to the following reasons.

With the development of construction technology, there are many high-rise buildings and high-rise apartment constructions that rise high into the sky, and with large-scale shopping malls and large-scale factory complexes that spread horizontally, construction that goes deep underground is increasing.

As a result, up to thousands of workers are dispatched per day, and work is distributed in many spaces vertically and horizontally, and the work of dozens or more than hundreds of temporary construction electrical facilities is complicated with each other, making it difficult for the construction company to manage work. There is a limit to the expansion of personnel.

While the objects to be managed are becoming vast and complex, the traditional management method by manpower is maintained.

For example, manpower-oriented safety management is when a manager lacks construction experience, when there is a safety problem in a specific space but is not aware of it, misunderstanding, unauthorized dismantling or moving of safety facilities, and communication between preceding and following work types. access, entering prohibited areas without the knowledge of workers, and not properly equipped with safety facilities.

The following are contributions from safety experts.

As any safety expert knows, there is a principle of cause linkage among the four principles of accidents. Every disaster has a cause. The most unfair thing about construction accidents is that even if the injured person works in compliance with safe work procedures, a disaster can occur if the wrong working conditions are created in the preceding process.

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

It is judged that the above conventional safety management method has a part that cannot manage vast and complicated work or safety facilities, equipment, and workers based on limited manpower and experience.

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

First, in the case of the risk assessment report, it proceeds as follows.

When drafting a hazard prevention plan, safety management plan, or construction plan at the beginning of construction, an initial risk assessment is conducted, and a risk assessment is prepared in consideration of the site situation before the work concerned. Write a process sheet.

Once unit work is classified, risk factors (human factors, mechanical factors, electrical factors, material factors, work characteristic factors, work environment factors, etc.) are identified for the work. Establish safety measures that can be taken on-site for the identified risk factors, and determine risks by reviewing the creator, construction manager, and safety manager.

A risk assessment meeting is conducted (participating the drafting partner, construction and safety staff of the construction company, and the site manager) by tallying up the week before the start of the work. Decide when and who will take action and check safety measures for the selected risk factors, and conduct delivery training until the day before work begins.

On the other hand, the risk assessment report mainly evaluates important and high-risk tasks, and evaluates some of the overall tasks, and the evaluation contents are prepared according to the partner's individual capabilities.

Therefore, there are tasks that have not been evaluated because the risk assessment does not cover all tasks. In particular, during the finishing work period, such as the interior, a lot of work is carried out at the same time, so it takes a lot of time and effort to prepare a risk assessment report and an evaluation meeting.

In addition, the content of the evaluation is subjective in that it depends on the ability of the partner company to write.

It is difficult to comprehensively know the current status of the evaluation target work on a time series by date, and it is difficult to comprehensively describe a specific task as parallel work, predecessor work, and successor work that have a precedence relationship. Among dozens of partner companies, it is difficult to write an evaluation report in the case of an office with a small number of employees or a work type without a computer.

On the other hand, the process table shows the time and date on the X-axis and the work contents are displayed in a bar-shaped bar chart or Gantt chart. Accordingly, there is an advantage in that it is possible to visually and easily grasp when a certain task starts and ends.

Milestones, however, are bar graphs of tasks, indicating when they are progressing, but do not contain any information about safety.

Safety management and process tables are used separately for different purposes.

In the prior art, the risk was evaluated mainly for major works, but in the present invention, the concept of a complete enumeration survey is introduced to evaluate the risk for all works in the field. This is because safety accidents occur not only in major work but also in minor work.

In the past, the causes of disasters were 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 following tasks that affect work is comprehensively analyzed in a time series.

From the conventional safety management based on individual experience and ability, it is possible to determine the risk quantitatively and immediately from the objective and systematic safety standards verified by a number of experts in advance.

In order to solve the above technical problem, the present invention

Evaluate the risks of temporary equipment, etc., necessary for partner companies to work.

Define what other dangerous tasks are in the same workspace.

By analyzing the influence of predecessor and successor tasks, comprehensively analyzes the current task in a time series in what state the preceding and following tasks must be in to be safe.

In order to determine whether a specific operation is dangerous, risk assessment standards are established through objective data standards, laws, regulations, cases, and expert opinions. Criteria for safety facilities (height, strength, size, time of installation, retention period, time of dismantlement), standards for working conditions (temporary electrical equipment working conditions such as temperature, humidity, wind, toxic gas, lighting, electric shock, pressure, etc.) , the schedule variance of the predecessor task (the condition in which the predecessor must complete), and the schedule variance with the successor task (the condition in which the successor must follow). These data are classified by type of work and made into a DB.

The method of collecting work information utilizes the master (total) schedule, monthly schedule, and weekly schedule, which have been done in the past without additional effort or institutional manpower input.

The risk assessment is conducted by the control unit after comprehensively determining how dangerous the environment surrounding the work set in the safety standard setting step is based on the contents analyzed from the process table.

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

Conventionally, the risk was evaluated only for high-risk or major work, but according to the present invention, the risk can be evaluated for almost all work in progress at construction sites and industrial sites. You can do a full inspection of all work.

In addition to the existing safety management activities, risks can be analyzed systematically and immediately without additional manpower, effort, time, institutions, and systems simply by creating a conventional process table.

In the past, risk assessment was strongly subjective in that the content varied depending on the individual evaluator's competency. However, according to the present invention, risk assessment is refined because objective and systematic safety standards such as opinions of expert groups, laws, regulations, safety standards, and cases are prepared in advance.

In the past, it was difficult to analyze preceding or following tasks that endanger a specific task, and even in the case of analysis, the analyst manually analyzed them, which took a great deal of time and effort, and the content was also 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 current task on the state. As a result, it became possible to systematically analyze not only the problem of a specific work itself, but also the relationship with the external environment surrounding a specific work (other types of work, precedence and follow-up work, top and bottom, left and right work).

In the past, it was used to figure out how much work is progressing through a schedule prepared by each partner or the speed of construction whether it is late or fast compared to the plan. According to the present invention, it is possible to determine which tasks are dangerous by analyzing the status of the tasks on the timeline table in which information on all tasks is recorded. In addition, since the schedule includes the start date, completion date, progress rate, etc. of a certain work, it is possible to accurately and quickly know how the site is progressing, and furthermore, by using it in the safety field, it is possible to evaluate safety more precisely and comprehensively, thereby preventing safety accidents. there is.

Figure 10 is an example showing the result of evaluating the risk by analyzing the integrated process table of FIG.

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

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 process table according to an embodiment of the present invention.

Referring to FIG. 1 , the safety information server 20 using the process table according to the present embodiment is responsible for receiving, determining, and providing safety information to the terminal 10 . The terminal 10 is responsible for inputting and querying process tables or safety information.

2 shows the configuration of a safety information generating device using a process table 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 process table database 22, a safety criteria database 23, and a safety information database 24.

The control unit 21 stores the process table in the process table database 22 and stores standards related to safety in the safety standard database 23. And after reading the work contents from the process table database 22 and conducting risk assessment, the result data is stored in the safety information database 24. And it is responsible for transmitting the contents of the database to the terminal 10 according to the user's request.

The process table database 22 stores process tables prepared by subcontractors for each work type, such as temporary civil engineering, construction, electrical equipment, and the like. Process schedules use process schedule creation programs, such as Pramavera and MS-Project.

The safety standards database 23 stores safety standards for specific operations. For example, the job title is septic tank cleaning, and the safety standards and rules are measuring the concentration of oxygen and harmful gases, performing ventilation, and wearing an air respirator or oxygen mask.

When the concentration of hydrogen sulfide is 20 ~ 30ppm, the olfactory nerve cells become fatigued, and even if the concentration is increased above that, it is not felt. When the concentration is 100 ~ 200ppm, the olfactory nerve is paralyzed, the feeling of resistance to hydrogen sulfide is reduced, and the opportunity to escape from danger is lost by lowering the alertness to higher concentrations of hydrogen sulfide. When the concentration of hydrogen sulfide exceeds 700ppm, the oxidation ability in the blood is exceeded and neurotoxicity occurs by attacking nerve cells.

The safety criteria database 23 also stores conditions of a preceding task or a condition of a succeeding task for a specific task. For example, in the work of a specific type of equipment, it is important whether or not the valve was closed in the preceding work. If the valve is not opened or closed temporarily, an explosion or pipe burst during subsequent work.

As a condition of the follow-up work, if a specific work involves spraying an insulation material with a high fire risk, the fire-resistant material coating work that surrounds the painting material must follow. If follow-up work is not started or followed late, the insulation coating is greatly exposed, increasing the risk of fire. Set the schedule difference or process rate difference between the current work of insulation spraying and the follow-up work of refractory material application. Since this difference may vary depending on the number of floors, area, etc., it is desirable to set it in consideration of site characteristics.

The safety information database 24 stores risk assessment information analyzed by the controller 21 . For example, the control unit 21 determines from the job information database 24 that job A is currently spraying insulation on the ceiling of the fourth basement floor at the time of evaluation, and that 75% of the total area has been sprayed. Then, the control unit 21 reads from the safety standards database 22 whether there is a preceding operation condition or a subsequent operation condition. As a follow-up condition, the refractory material coating work (Task B) must be started within 2 days from the date of work A.

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

3 is an example of a conventional process table. This is a time table created by Primavera, a representative program for creating time tables.

The process table is prepared including the name (location) of the work, the number of working days, the start date, the completion date, the progress rate, and the order of work. A milestone is a chart that implicitly displays a lot of information that can tell not only the person's information but also the surrounding environment, such as the birth, death, age, father, and descendant kinship relationship, just like a person.

4 is a flowchart illustrating a safety information work process between a construction company and a partner company for generating and providing safety information using a process table according to each embodiment of the present invention.

First, referring to FIG. 4 according to an embodiment, the construction company and the partner create safety standards for a specific work (S10).

For example, safety standards and rules for septic tank cleaning include measuring the concentration of oxygen and harmful gases, performing ventilation, and wearing a respirator or oxygen mask.

In the case of electrical equipment, the order of work is established, and the condition that the successor work should not be started in case the previous work is not completed or the current state is in any case is set. In the case of electrical room construction, it is a criterion that no work can be performed while electricity is on. In the case of construction, it is the same condition that work cannot be started unless safety facilities are classified.

When the safety criteria are created, they are systematically stored in the safety criteria database 23 (S20). Here, as the system, a work breakdown system suitable for field construction characteristics may be created or a conventional civil engineering, construction, and electrical equipment work type code may be used.

Now, when the construction begins, the partner creates a process table (S30). For example, in facility construction, when the vertical piping of equipment in the machine room on the 4th basement floor is started, the work details are displayed on the process table. Personnel or equipment safety concerns may also be included. There are master schedules for the entire construction period and weekly schedules for each week. Among them, the weekly schedule is judged to be more effective in assessing the risk of work because the contents are detailed and detailed.

When the process table is prepared, risk assessment is performed as the next step (S40). The control unit 21 reads job information from the process table. In addition, safety criteria related to a specific task are read from the safety criteria database 23. Then, work information and safety standards are compared. As a result of comparison, if the safety standard is exceeded, it is quantitatively determined that there is a risk. The determination result is systematically stored in the safety information database 24.

For example, if there is a welding operation in the space where the insulation spray coating is applied, the control unit determines that the insulation spray coating is unsafe because it is a material that can catch fire. In addition, by comparing the start date or progress rate of insulation spraying and the start progress rate of refractory material coating, which is a follow-up work condition, it is evaluated that there is a risk if it deviate from the standard. In the case of facilities, if there is a pipe pressure test of a specific line today, check whether steam was discharged the previous day. If water vapor in the pipe is not discharged, it is judged that an explosion may occur during the pressure test.

In the case of electricity, when electricity is supplied to the electrical room, the electricity must be cut off because there is a risk of electric shock when water-related work is performed. In addition, it is determined whether there is any 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 facility equipment of the work itself for performing the work with respect to the specific work. In addition, it comprehensively judges the risks of the preceding tasks surrounding a specific task, the following task conditions, the work process, and the tasks occurring in the space above, below, left, and right. In addition, the control unit 21 comprehensively evaluates the mutual influence and risk between all operations in the field with reference to the standards set in the safety standard 23.

As a result of the determination of the control unit 21, when work details are missing or difficult to read among the contents of the process table, and when there is no necessary information, a query is created. Regarding the query, if the manager of the partner or construction company checks the contents and corrects the process table 22 or writes an answer, the control unit 21 refers to the answer and re-executes the risk assessment (S40) (S50).

Next, when the risk evaluation (S40 to S50) is completed, the control unit 21 stores the evaluation result in the safety information database 24 and outputs that the evaluation has been completed to the terminal 10 (S60).

For example, the prime contractor who oversees all partners can view all safety information (24). Waterproofing construction partners inquire the details of the risk assessment related to waterproofing construction through a PC or smartphone.

Additionally, the control unit 21 may create countermeasure information such as risk-related measures, procedures, and regulations. Countermeasure information may be prepared in advance in the safety standard database 23 and utilized.

After confirming the contents in the risk confirmation step (S60), the contractor or the partner worker takes necessary safety measures and then inputs the result of the measures into the safety information database 24.

The following shows an embodiment of a specific operation of a construction site according to the present invention from FIGS. 5 to 10.

5 is an example of setting safety criteria for a specific operation according to the present invention. Referring to Figure 5, it is a process of constructing polyurethane foam on the ceiling for insulation of the basement floor, from the 4th basement floor to the 1st basement floor, and the partner is ○○ company.

First of all, the first column shows safety standard items newly proposed in the present invention. In the second column, safety criteria are established.

First of all, the first item of the first column, the worker's self-inspection, is the safety standard that ○○ company must abide by while constructing polyurethane foam, an insulation material. It is necessary to check equipment and temporary scaffolding for constructing polyurethane foam.

The second is a dangerous work in the same working space, which establishes that it can be unsafe by working with other types of work within the layer and space where polyurethane foam is constructed. For example, if the words or meanings of facility plumbing, welding, temporary lighting, high-speed cutting machine, thinner, and paint are carried out together in the same space by partners with different meanings, a fire may occur. This is because the polyurethane foam sprayed on the ceiling is vulnerable to fire and can burn, causing serious disasters by emitting toxic gases.

The third item is a condition of preceding work, and there may be a work that needs to be constructed first before constructing the current work. For example, if the current work to be done is external wall masonry, external scaffolding should be installed.

The fourth item is the post-work condition, which sets the state of the work that will follow later in constructing the current work or what kind of relationship it has with the current work. As shown, polyurethane foam is weak against fire, so after constructing polyurethane foam on the ceiling, a fire-resistant coating should be sprayed on it as a subsequent process to prevent fire.

However, if the fire-resistant coating, which is a protective material, is not sprayed or the follow-up speed is slow despite the completion of the construction of polyurethane foam on the ceiling, the risk of fire due to sparks increases. The schedule difference is a standard for how many days the polyurethane foam and fireproof coating should be processed.

Since the range of polyurethane foam spraying is not large for 1 to 2 days, damage is limited even in case of fire. Increased fire risk and damage.

Since the schedule difference and the progress rate difference are newly presented according to the present invention, it is preferable that construction officials determine the criteria in consideration of the construction space and the area to be sprayed.

The fifth item is the dangerous work in the upper, lower, left and right space, and describes the type of work that becomes dangerous when the current work is constructed next to the upper floor and the lower floor. For example, if water enters the electrical room on the lower floor due to a fall hazard caused by simultaneous vertical work or a work in which water may pour from the upper floor, an electric shock accident caused by high-voltage electricity may occur.

As described above, if the prior art has focused on unstable work within the same space, the present invention emphasizes the importance of the relationship between the previous work and the subsequent work. This is because, in most cases, the process of completing a specific space and proceeding with finishing work and electrical installation work is mutually influenced in a serial relationship rather than an independent work.

Although safety standards utilize conventional related laws and guidelines, it is effective to additionally introduce the concept of process management to prevent safety accidents, analyze what is affected between tasks in a time series, and set safety standards by limiting the scope of the influence. is considered to be very large.

Overall, the status of all work in the field is grasped at the lowest level as possible through a process table every day, and the risk of safety accidents increases if the safety management standards are deviating from the above. Knowing the problem is paramount, and a solution can be established and acted upon sufficiently with current technology.

As a next step, FIGS. 6 to 8 show a weekly milestone.

First, Figure 6 is an example showing a process table of partners who perform insulation work according to the present invention. It is similar to the conventional process table, can be created on the web of Excel or PMIS, and is prepared using a program specializing in process table creation.

In the first column, the list of work performed by the partner from the previous week and this week, in the second column, the number of working days, in the third column, the start date of the task, and in the fourth column, the completion date of the task. In the right bar chart bar display area, bars are displayed according to the start and finish dates of the work, making it easy to visually understand the process progress.

Looking at the process schedule, it shows that the work of spraying polyurea foam on the ceiling was carried out in the machine room on the 4th basement level and zone A on the 1st basement floor, and the work started today in zone B on the 1st basement floor.

The partner knows where and what kind of work the workers of their company are doing and gives work instructions, so you can write a schedule with those contents.

7 is an example showing a process table prepared by a partner performing a fireproof coating operation according to the present invention. When the polyurea foam spraying operation of FIG. 6 proceeds, the fire-resistant coating of FIG. 7 is sprayed thereon. Figure 6 is the current task and Figure 7 is the follow-up task. As the distance between FIGS. 6 and 7 increases, the risk of fire increases.

8 is an example showing a process table prepared by a partner who works on fire piping according to the present invention. It describes that the work is in progress in the machine room on the 4th basement floor.

Above, among the process tables prepared by a number of partners, examples of process tables related to the machine room on the 4th basement floor were shown in FIGS. 6, 7, and 8. Partners need to create a process table that their company is doing, as shown in FIGS. 6 to 8.

When each supplier creates a schedule, the number of pages is large, so it is necessary for the prime contractor to gather them all in one place. In FIG. 9, the process tables prepared in FIGS. 6, 7, and 8 are integrated and displayed.

10 is an example showing the result of risk evaluation by analyzing the integrated process table of FIG. The polyurea foam spraying started on September 27th and the work is coming to an end, but the fireproof coating construction for fire prevention started late on October 1st, so the polyurea foam is exposed to fire.

The control unit 21 determines whether the schedule difference and the process rate difference exceed the post-work condition and displays the risk evaluation result. Looking at the contents of the evaluation, as of October 1st in the machine room on the 4th basement level, almost 80% of the polyurea foam coating was sprayed on the ceiling. I am working on cleaning the connecting parts with thinner. And the fireproof cladding work is about to begin.

If the pipe is cut with a cutter, sparks fly, and if it sticks to the thinner, it catches fire, and if it moves to the ceiling, most of the polyurea foam catches fire. This is because the follow-up process, spraying fireproof coating, follows late.

Currently, the machine room is evaluated as having a very high risk of fire as several workers are working.

In the past, polyurea foam caught fire on the basement floor and serious accidents caused by smoke were reported in the news several times.

The cause of the accident is generally focused on the management of cutters and thinner flames, 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 process, and follow-up When the process conditions are analyzed three-dimensionally in a time series, the cause is that the fire-resistant coating, which is a follow-up process, started late and followed up late, failing to protect the pole urea foam from flames through the fire-resistant coating. If the application of the present invention pointed out in advance that the start of the fire-resistant coating would be delayed, the fire would not have occurred or the damage would not have been great through the measures.

As described above, one example was given in the present embodiment, but according to the present invention, various risks ranging from major disasters to minor disasters that exceed systematically set safety standards in advance for work in all spaces in construction and industrial sites Because it evaluates quickly and accurately, necessary measures can be taken, and as a result, safety accidents do not occur.

Process Table and Safety Criteria The safety evaluation database can be used within the process table preparation program itself by adding functions to Primavera, a commercial professional process management program, and MS-Project. If the conventional process table creation program was used only for process table creation, it is a form in which the safety management function is added to the program.

Since the schedule has all the construction information, the risk can be assessed quickly and accurately.

Another method is to add a database function related to safety in the PMIS, and the process table can be prepared in a specialized program such as Primavera, MS-Project, or an Excel file, and read and use the file.

The milestone is displayed as a bar chart and a kand chart with the name of the task, the start date and the completion date. In the present invention, the schedule includes a document having information on a process or construction schedule containing information on which tasks are started and when they are finished.
