Abstract

In accordance with the present invention, in order to prevent a disaster in construction and industrial sites, a control part analyzes and evaluates content about the occurrence of a safety disaster between activities on a network process schedule, thereby quickly and accurately evaluating riskiness to take prevention measures. In accordance with the present invention, a riskiness evaluation method using a process schedule includes: a first step in which construction-related people set safety criteria by defining internal and external items, which can cause a disaster, with respect to each job and determining relations with parallel, preceding and following jobs; a second step in which each cooperator makes a process schedule while performing construction; a third step in which a control part analyzes content of the process schedule; a fourth step in which the control part evaluates riskiness by job by determining whether the content of the process schedule of the second or third step exceeds the safety criteria of the first step; and a fifth step in which if the safety criteria is exceeded as a result of comparison in the above step, the control part determines that there is a risk. Therefore, when a process schedule is made, riskiness by job is quickly and accurately analyzed, which can lead to the prevention of a disaster.

Description

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

The present invention is to prevent safety disasters occurring during construction at construction and industrial construction sites, and more specifically, by using the construction progress information of a schedule prepared by multiple partners in the temporary civil engineering construction and electrical equipment construction fields, the control unit performs the preceding work It is about analyzing and evaluating the risk in the case where dangerous work is concurrently performed in the same space when it is not completed or the follow-up work does not follow, so that actions can be taken in advance.

In the case of OECD occupational accidents, the number of fatalities per 100,000 people was 3.0 and 7.0 in Korea, which is twice that of the OECD (Jungang 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 was 9656, which means that there are more than 10 injuries per hour. Among them, the number of construction accidents accounted for 29.3% of all industries, and the total number of fatal accidents was 1,777, with more than one fatality occurring every 5 hours.

The number of fatal accidents in 2016 was 969 across all industries, of which 499 died from accidents in the construction industry, or 51.5% of all industries (construction economy 2017.05.25).

Efforts are being made to prevent accidents that occur during construction at construction sites, such as worker safety education, implementation of a risk assessment system before starting work, improvement of related systems, expansion of facilities and human investment, and strengthening of penalties and penalties.

In spite of these efforts, it is judged that the reason why the number of accidents did not decrease is due to the following reasons.

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

As a result, up to thousands of workers per day are distributed vertically and horizontally in many spaces, and the work of dozens or hundreds of temporary construction electrical installations is complicated with each other, making it difficult for construction companies to manage their work, and safety managers There is a limit to expanding the staff.

While the subject of safety management becomes vast and complex, the traditional management method by manpower is maintained.

For example, personnel-oriented safety management is when the manager lacks construction experience, there is a safety problem in a specific space but does not recognize it, misunderstanding, dismantling or moving safety facilities without permission, and poor communication between preceding and following construction types. There are a number of problems, such as entering a prohibited area without the knowledge of workers, and not properly equipped with safety facilities.

The following is a contribution from a safety expert.

As any safety-related expert knows, there is a principle of cause connection among the four principles of disasters. All disasters have a cause. The most unfortunate thing about construction accidents is that no matter how much the injured person complies with the safety work procedures, if the wrong working conditions are created in the preceding process, a disaster can occur.

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

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

As documents related to safety management, there are a risk assessment report, a hazard prevention plan, a night work permit, and a work report.

First, in the case of a risk assessment, the process is as follows.

In the early stage of construction, when preparing a hazard prevention plan, safety management plan, or construction plan, an initial risk assessment is carried out, and a risk assessment is prepared in consideration of the site situation before the relevant work. Create a schedule.

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

A risk assessment meeting (participating partner companies, construction company construction and safety staff, and site managers attending) is conducted by tallying the data the week before the start of the relevant work type. It determines when and who takes action and confirms safety measures for the selected risk factors, and conducts delivery training until the day before the start of the work.

On the other hand, the risk assessment report is important and evaluates a part of the entire work, focusing on the work with a high risk level, and the evaluation contents are being prepared according to the individual capabilities of the partners.

Therefore, there are some tasks that have not been evaluated because the risk assessment document does not cover the entire work. In particular, during the finishing construction period, such as 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 highly subjective, depending on the competency of the partner's author.

It is difficult to comprehensively understand the status of the work to be evaluated on a time series by date, and it is difficult to comprehensively describe it as a follow-up work for a parallel work that has a precedence for a specific work. Among dozens of partner companies, it is difficult to write an evaluation in the case of an office where a small number of workers work or a work without a computer.

On the other hand, the timeline shows the time and date on the X-axis and displays the work contents in a bar chart or Gantt chart. Accordingly, there is an advantage of being able to visually easily grasp when a certain task starts and when it ends.

However, the milestones are bar markers of the work, indicating when to proceed, but do not contain any safety-related information.

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

In the prior art, the risk was mainly evaluated based on the main work, but in the present invention, the concept of a total investigation for evaluating the risk for all the work in the field is introduced. This is because safety accidents occur not only in major work but also in minor work.

In the past, the cause of a disaster was identified mainly by problems visible in a specific space, but in the present invention, in addition to the conventional analysis method, the causal relationship between the preceding work and the subsequent work affecting the work is comprehensively analyzed in a time series.

It enables quantitative and immediate risk judgment from the objective and systematic safety standards verified by many experts in advance from the safety management centered on individual experiences and abilities.

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

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

Define what other hazardous tasks are in the same workspace.

By analyzing the influence of the predecessor task and the successor task, it is analyzed comprehensively in the time series to determine what state the predecessor task must be in to make the current task safe.

In order to determine whether a specific task is dangerous, risk assessment standards are established through objective data standards, laws, regulations, cases, expert opinions, etc. Standards for safety facilities (height, strength, size, installation time, retention period, dismantling time), standards for working conditions (temperature, humidity, wind, toxic gas, lighting, electric shock, pressure, etc. working conditions for construction temporary electrical equipment) , including schedule differences between predecessor tasks (condition that the predecessor task must be completed), and schedule differences from successor tasks (condition that successor tasks must follow). These data are classified by work type and work type and made into a DB.

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

The risk assessment is carried out by comprehensively judging how dangerous the environment surrounding the work set in the safety standard setting stage and the contents analyzed from the process table is the control unit.

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

In the prior art, risks were evaluated only for high-risk or major operations, but according to the present invention, risks can be evaluated for almost all operations performed at construction sites and industrial sites. A full investigation can be done on all work.

In addition to the existing safety management activities, it is possible to analyze risks systematically and immediately by simply creating the conventional schedule without inputting additional manpower, effort, time, system, or system.

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

In the past, it was difficult to analyze the preceding or succeeding tasks that endanger a specific task, and even in the case of analysis, the analyst manually analyzes it, which takes a lot of time and effort, and the content is also strongly subjective. According to the present invention, it is possible to accurately grasp how a preceding or a subsequent task related to a specific task will affect the current task status. Accordingly, it became possible to systematically analyze not only the problem of the specific work itself, but also the relationship with the external environment surrounding the specific work (different types of work, preceding and following work, up, down, left and right work).

Conventionally, it has been used to determine how much work is progressing, or whether it is late or fast compared to the plan, through the schedule prepared by each partner. According to the present invention, it is possible to determine which task is dangerous by analyzing the state of the process table in which the information of all jobs is recorded. In addition, as the process table includes the start date, completion date, and progress rate of a certain task, it is possible to know exactly and quickly how the site is progressing. have.

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 inquiring 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 the present embodiment includes a control unit 21 , a process table database 22 , a safety standard database 23 , and a safety information database 24 .

The control unit 21 stores the process table in the process table database 22 and stores safety-related standards in the safety standard database 23 . And after reading the work contents from the process table database 22 and performing 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 schedule database 22 stores the schedule prepared by partners for each type of construction, such as temporary civil engineering, construction, electrical equipment, and the like. The milestone program uses a milestone preparation program, and there are Pramavera and MS-Project.

The safety standard database 23 stores safety standards for specific tasks. For example, the name of the work is cleaning the septic tank, and the safety standards and rules are measuring the concentration of oxygen and harmful gas, performing ventilation, and wearing an air respirator or oxygen mask.

When the concentration of hydrogen sulfide reaches 20 to 30 ppm, the olfactory nerve cells become fatigued, and even if the concentration is increased beyond that, it is not felt. When the concentration is 100~200ppm, the olfactory nerve is paralyzed, the rejection of hydrogen sulfide is reduced, and the vigilance against higher concentration of hydrogen sulfide is lowered, so that the opportunity to escape from danger is lost. When the concentration of hydrogen sulfide exceeds 700ppm, the oxidative capacity in the blood is exceeded, and neurotoxic action occurs by attacking nerve cells.

The safety standard database 23 also stores the condition of the preceding operation or the condition of the subsequent operation for a specific operation. For example, it is important whether the valve is closed in the preceding work in the work of a specific equipment work. If the valve is not temporarily opened and closed, it is a case of an explosion or a pipe burst when performing work in a subsequent work type.

As a condition for follow-up work, if a specific work sprays insulation with a material with a high fire risk, the fire-resisting material coating work surrounding the painting material must be followed. If the follow-up work is not initiated or followed late, the insulation coating will be greatly exposed, increasing the fire risk. Set the schedule difference or process rate difference between the current work of spraying insulation and the subsequent work of applying refractory materials. Since this difference may vary depending on the number of floors, the area, etc., it is desirable to set it in consideration of the site characteristics.

The safety information database 24 stores risk assessment information analyzed by the control unit 21 . For example, the control unit 21 determines from the work information database 24 that the work A is spraying insulation on the ceiling of the fourth basement floor at the current evaluation time and spraying 75% of the total area. And the control unit 21 reads from the safety standard database 22 whether there is a preceding operation condition or a subsequent operation condition. As a follow-up work condition, the fire-resisting material application work (task B) must be started within 2 days from the start date of work A.

Alternatively, if the difference between the process rates of operation A and operation 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, if it is judged whether there is electric welding or gas welding work on the same floor or room, it is evaluated that the risk of fire is high. The analysis result as described above is stored in the safety information database 25 .

3 is an example of a conventional process table. This is a milestone created by Primavera, a representative milestone creation program.

The process table is prepared including the name (location) of the work, the number of work days, the start date, the completion date, the progress rate, and the work precedence relationship. A milestone table is a chart that contains 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, descendant, and relative relationships.

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, a construction company and a partner prepare safety standards for a specific operation (S10).

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

In the case of electrical equipment, the order of the work is established and the condition that the follow-up work should not be started if the preceding work is not completed or the current status is set. In the case of electrical room construction, it is a standard that any work cannot be performed while electricity is on. In the case of construction, it is the same condition as not being able to start work unless safety facilities are identified.

When the safety standards are written, they are systematically stored in the safety standards database 23 (S20). Here, the system can create a work breakdown system suitable for the characteristics of on-site construction or use a conventional civil, building, and electrical installation code.

Now, when construction begins, the partner prepares a schedule (S30). For example, when the vertical piping of the machine room on the 4th basement floor is started in facility construction, the work details are displayed on the process table. Personnel or equipment safety concerns may also be included. There are two types of timetables: a master timetable that writes the entire construction period, and a weekly schedule that is written on a weekly basis. Since the weekly schedule is detailed and detailed, it is judged to be more effective in assessing the risk of work.

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

For example, if there is a welding operation in the space where the insulation spraying is performed, the control unit determines that the insulation spraying is not safe because it is a material that can cause a fire. In addition, it is evaluated that there is a risk if it deviates from the standard by comparing the start date or progress rate of the insulation spraying with the progress rate of the refractory material application, which is a follow-up work condition. In the case of equipment, if there is a pressure test of a pipe in a specific line today, check whether water vapor 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, if there is electricity in the electrical room, there is a risk of electric shock if water-related work enters, so electricity must be cut off. In addition, it is judged 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 case of a leak.

In this way, the control unit 21 measures the preparation facility equipment of the worker itself for performing the corresponding operation for a specific operation. In addition, it comprehensively judges the risks of the preceding work surrounding the specific work, the following work conditions, the work process, and the work occurring in the upper, lower, left, and right spaces. In addition, the control unit 21 comprehensively evaluates the mutual influence and risk between the operations for all operations in the field with reference to the standards set in the safety standards 23 .

As a result of the judgment of the control unit 21, if there is no necessary information in the case where the work contents are omitted or difficult to read in the contents of the process table, a query is prepared. When the manager of the partner or construction company checks the contents and corrects the process table 22 or writes an answer to the inquiry, the control unit 21 performs the risk assessment (S40) again with reference to the answer (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 is completed to the terminal 10 (S60).

For example, a prime contractor who oversees all partner companies can view all safety information 24 . The waterproofing contractor inquires about the risk assessment of the waterproofing project through a PC or smartphone.

Additionally, the control unit 21 may create countermeasure information such as a risk-related measure method or a procedure book, regulation, regulation, and the like. The countermeasure information may be prepared in advance in the safety standard database 23 and utilized.

After confirming the contents in the step of confirming the risk (S60), the construction company or the worker of the partner company takes necessary safety measures and 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 standards for a specific operation according to the present invention. Referring to FIG. 5 , it is a process of installing polyurethane foam on the ceiling for insulation of the basement.

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

First of all, the first item in the first column, the self-inspection item, is the safety standard that ○○ companies must follow during the construction of polyurethane foam, which is an insulating material. It is necessary to check the equipment and temporary equipment for the construction of polyurethane foam.

The second is dangerous work in the same work space, and it establishes that it may not be safe by working with other types of work within the floor and space where polyurethane foam is installed. For example, if the words or meanings of plumbing, welding, temporary lighting, high-speed cutting machine, thinner, or paint are carried out together in the same space by partners with different meanings, a fire may occur. Polyurethane foam sprayed on the ceiling is weak against fire and can burn, and it can cause serious disasters by spewing poisonous gas.

The third item is a prerequisite for the construction of the current work, and there may be a work to be constructed first. For example, if the current work is masonry for an exterior wall, an exterior scaffolding must be installed.

The fourth item is the condition for follow-up work, which establishes what kind of state or relationship with the current work should be in the construction of the current work. As shown, since polyurethane foam is weak against fire, it is necessary to prevent a fire by spraying a fireproof coating on it as a follow-up process after the polyurethane foam is installed on the ceiling.

However, even though polyurethane foam has been installed on the ceiling, if the fire-resistance coating, which is a protective material, is not sprayed or the following speed is slow, the risk of fire due to flame increases. The schedule difference is the standard for how many days difference between polyurethane foam and fire-resistance coating should be.

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 above schedule difference and the difference in progress rate are newly proposed according to the present invention, it is preferable that the standards are determined by those involved in the construction in consideration of the construction space and the area to be sprayed.

The fifth item is hazardous work in the upper, lower, left, and right spaces. For the current work, the type of work that becomes a dangerous situation when constructed next to the upper floor or lower floor is selected and described. For example, if water enters the electrical room on the lower floor, an electric shock accident may occur due to high-voltage electricity, since a fall disaster caused by vertical movement, or work that may cause water to spill from the upper floor is carried out.

As described above, if the prior art focused on unsafe work in the same space, the present invention emphasizes the importance of the relationship between the preceding work and the succeeding work. This is because, in most cases, the process of completing a specific space and carrying out finishing work and electrical installation work is a serial relationship rather than a single work, and mutually influences each other in most cases.

The safety standard utilizes the related laws and guidelines, but it is effective to introduce the concept of process management to prevent additional safety accidents, analyze the influences between jobs in the time series, and limit the scope of the influence to set the safety standards as safety standards. is considered to be very large.

Comprehensively, the status of all work in the field is grasped every day at the lowest possible level through the process table, and if the above safety management standards are deviated, the risk of safety accidents increases. Knowing the problem is of the utmost importance, and solutions can be established and acted upon with current technology.

As a next step, Figures 6 to 8 show the weekly schedule.

First, FIG. 6 is an example showing a process table of a partner performing an insulation operation according to the present invention. It is similar to the conventional timetable, and it can be prepared on the web of Excel or PMIS, and it is prepared using a program specializing in creating a schedule.

In the first column, the list of work performed by the supplier this week and the previous week, the second column is the number of work days, the third is the start date of the work, and the fourth is the completion date of the work. On the right side of the bar chart bar display area, bars are displayed according to the start and completion dates of the work so that the process progress can be easily understood visually.

If you look at the process table, it shows that the work of spraying polyurea foam on the ceiling is in progress in the machine room on the 4th basement level and in Zone A on the 1st basement floor, and the work starts on the 1st basement floor in Zone B on this day.

The partner company knows where and what kind of work the workers of their company are doing and gives the work order.

7 is an example showing a process table prepared by a partner performing a fire resistant coating operation according to the present invention. When the polyurea foam spraying operation of FIG. 6 is performed, the operation of spraying the fire resistant coating of FIG. 7 on it follows. Fig. 6 is the current work and Fig. 7 is the follow-up work. 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 performing fire extinguishing piping work according to the present invention. It describes that work is in progress in the machine room on the 4th basement floor.

As described above, among the process tables prepared by a number of partners, the process tables related to the machine room on the 4th basement floor are shown in FIGS. 6, 7, and 8 and examples. It is necessary for business partners to prepare a schedule that their own company is doing as shown in FIGS. 6 to 8 .

When each partner prepares a schedule, the number of pages is large, so it is necessary for the original contractor to collect them 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 results of risk evaluation by analyzing the integrated process table of FIG. Polyurea foam spraying started on September 27 and the work is being completed, but the fire-resistance coating construction for fire prevention started late on October 1, leaving the polyurea foam exposed to fire.

The control unit 21 determines whether the difference between the schedule difference and the process rate exceeds the follow-up operation condition, and displays the risk evaluation result. According to the evaluation contents, as of October 1, in the machine room on the 4th basement level, almost all of the polyurea foam spraying is being sprayed on the ceiling at 80%, and on the same indoor floor, the pipe pipe is cut with a high-speed cutter for installation of the facility sprinkler fire extinguishing pipe, and the pipe I am working on cleaning the connecting parts in a thinner. And the fireproof coating construction is about to start now.

When 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, fireproof coating spraying, will follow later.

Currently, the machine room is evaluated to have a very high risk of fire as various types of work are being performed.

In the past, polyurea foam ignited in the basement and serious disasters caused by smoke have been reported in the news several times.

Although the cause of the accident is generally focused on the management of the cutter and the flame of the thinner, if you look 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 the upper and lower work, the preceding process and the following When the conditions of the process are analyzed three-dimensionally in a time series, the fire-resistance coating, the follow-up process, started late and followed later, and it is also the cause of the failure to protect the polyurea foam from the flame through the fire-resistance coating. If it was pointed out in advance that the start of the fire resistant coating would be delayed through the application of the present invention, the fire would not have occurred or the damage would not have been large through the measures.

As described above, one example has been given in this embodiment, but according to the present invention, various risks from major disasters exceeding safety standards systematically set in advance for work in all spaces in construction and industrial sites are reduced. Because it evaluates quickly and accurately, necessary actions can be taken, and as a result, safety accidents do not occur.

The process table and safety standard safety evaluation database can be used within the process table preparation program itself by adding functions in Primavera and MS-Project, which are commercial professional process management programs. If the conventional process table preparation program was used only for process table preparation, the safety management function is added to the program.

Since the schedule has all construction information, it is possible to quickly and accurately evaluate the risks.

Another method is to add a database function related to safety in PMIS, and the process table can be written in Primavera, MS-Project or Excel file, which is a professional program, and read the file to use.

A timeline is displayed in a bar chart Kant chart with the name of the task, the start date and the finish date. The schedule in the present invention includes a document having information about a process or a construction schedule containing information about which tasks are and when they start and when they end.
