Description

  Embodiments described herein relate generally to a construction management system and construction management method for process management and area management of construction in a plant facility or the like.

  Carry-in / installation work of each device / device in the construction of a plant or renewal work / inspection work of some of the equipment / devices of the plant equipment is performed within a limited construction period in the entire process. Since there are a plurality of equipment / device supply companies or maintenance companies in the plant, there are a plurality of construction companies. In addition, each work is subdivided into a plurality of work items. However, based on the construction system in the company in charge of the construction, there are a plurality of work subjects responsible for each work item.

  In addition, in the case of plant construction as well as in periodic inspections, a plurality of constructions are performed in parallel. Alternatively, even when only one construction is performed, a plurality of operations may be performed in parallel. Therefore, a plurality of operations are often performed in the same area and the same time.

  In a situation where multiple operations are performed in parallel in a confined area, there is a high risk of delay in construction progress, disasters, and quality nonconformity in order to proceed with the work schedule while maintaining safety and quality. It is necessary to grasp construction contents and areas and to manage them with priority.

  Conventionally, a method of managing a work process and its work section in a plant facility using a process management system has been proposed. Persons in charge of each group or construction company show and show the areas required for work, and if there is interference, prevent work accidents as well as work delays by adjusting the date and time and reducing the work area. I am trying. In addition, it has been well confirmed that measures to reduce disaster risk in work are taken before the start of the work.

  Hereinafter, a construction management system according to an embodiment of the present invention will be described with reference to the drawings. Here, the same or similar parts are denoted by common reference numerals, and redundant description is omitted.

[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of a construction management system according to the first embodiment. The construction management system 100 includes a storage device 10, an arithmetic device 20, an input unit 30, and an output display device 40. Specifically, the construction management system 100 is a computer system.

  It is assumed that the construction management system 100 is a system that manages all construction works performed in the plant, and is a shared system of members involved in all construction works performed in the plant.

  The storage device 10 includes a process information storage unit 11, a work content information storage unit 12, and a risk degree storage unit 17. The computing device 20 includes an interference evaluation unit 21 and a risk evaluation unit 22.

  FIG. 2 is a flowchart showing a procedure of the construction management method according to the first embodiment. First, a database, that is, a process information storage unit 11 and a work content information storage unit 12 are prepared (step S10).

  FIG. 3 is a diagram illustrating an example of basic process data stored in the process information storage unit. FIG. 3 shows, as a simple example, a process in which the A construction, the B construction, and the C construction are performed in parallel. In each construction, a plurality of works are performed.

  For example, if the A construction is an update construction of the control system, a plurality of works are performed for this construction. That is, disconnection work around the current control panel (operation A1), removal / unloading work of the current control panel (operation A2), cable laying around the new control panel (operation A3), installation / installation of the new control panel (operation A4) ), Cable connection to the new control panel (operation A5), and testing (operation A6). For example, in work A2 and work A4, areas other than the control panel installation place are also work places.

  In addition, not only the works are performed in parallel, but also in the A work, there is a period in which the work A2, work A4, and work A3 are performed in parallel.

  FIG. 4 is a table showing an example of detailed process data stored in the process information storage unit. Information as process data is information input from the input unit 30 and includes a work name (work item) and a start date and an end date and time for each work name. The work described in the work name column may be, for example, work in the same work or work belonging to different works.

  FIG. 5 is a screen showing a display example based on the process data stored in the process information storage unit of the construction management system according to the first embodiment. The top row shows the year and month, and in the second row and below, each column shows the day. On the calendar, work items are displayed in a bar graph extending in the horizontal direction. From the top to the bottom of the screen, bar-shaped displays are arranged in order of the start date.

  FIG. 6 is a table showing an example of work content information data which is work information stored in the work content information storage unit. Each line is information for each work item. The information items in each column include a construction name, work items, work procedures / procedures, work areas (area sections), and work periods.

  For example, regarding the A construction, the work item A1 to the work item A6 are expanded in each row. The work procedure / procedure is information related to the contents of each work, but when data is prepared in advance, as shown in FIG. 6, the book data of the work procedure manual or work procedure manual relating to the work is used as the book data. Is associated with the system.

  The work area indicates information on the location in the construction area (site) of the target work where each work is performed, and is defined by the work procedure and procedure, but in the work content information data according to the present embodiment, In particular, an item of work area information regarding the work area is provided as an “area section”. The information in the period column is extracted from the process information data stored in the process information storage unit 11 in conjunction with the process information storage unit 11.

  FIG. 7 is a table showing the relationships of the work parties in the construction management system. FIG. 7 shows one work item. A work manager (Supervisor) manages the work. When one construction includes, for example, work in a plurality of sections such as mechanical relations, electrical relations, and instrumentation relations, a work manager is often present for each of these plural sections. In addition, among these categories, work belonging to the same category, for example, instrumentation, is often managed by an instrumentation-related work manager.

  The work group is a member of a contract company that undertakes work, for example, and is composed of a plurality of workers (Work Members). There are conductors (Leaders) among the workers, and other workers perform work under the direction and instruction of the conductor. An instructor (Technical Engineer) is, for example, an engineer dispatched from a factory. In the case of a machine-related, the instructor may carry out the work himself, but may also provide installation guidance to a work group. In addition, in the case of instrumentation-related or electrical-related, there are many cases in which tests, adjustments, etc. are performed without receiving work instructions. Since the work group and the instructor perform the actual work, these are collectively referred to as a worker.

  In addition to this, there are people who are not actual workers but who enter the plant as a primary visitor for, for example, a field survey. This primary visitor will be called a non-resident.

  FIG. 8 is a table showing an example created from work information stored in the work content information storage unit with particular attention to area section data related to area sections. The section data as information input from the input unit 30 is a work name, an area section symbol used in the work, a start date and time, and an end date and time.

  FIG. 9 is an input example of an input screen for inputting a specific range of area sections. That is, a diagram of the target room is displayed on the input screen. The area section is input on this screen by tracing the necessary area with, for example, a touch pen. It is also possible to define building coordinates and input the coordinates of each corner. FIG. 9 shows an input example of the five types of area sections shown in FIG.

  After step S10, as shown in FIG. 2, the interference evaluation unit 21 of the arithmetic unit 20 performs an area interference check (step S20). The area interference check in the interference evaluation unit 21 is performed as follows, for example.

  That is, by designating a predetermined period, the interference evaluation unit 21 extracts a work name, a work item, and a work period of work performed simultaneously from the process information data of the period stored in the process information storage unit 11. At the same time, the work area information stored in the work content information storage unit 12 for each of these work items is extracted. And the interference of the some operation | work in a work area is evaluated by determining the presence or absence of the duplication in the time series of the extracted work area.

  As described above, in the present embodiment, since the process information data stored in the process information storage unit 11 is automatically extracted in the work content information storage unit 12, the interference evaluation unit 21 substantially The area interference check based on the process information stored in the process information storage unit 11 and the work area information stored in the work content information storage unit 12 is performed only by referring to the work information stored in the work content information storage unit 12. Can be done.

  FIG. 10 is an example of an output display screen that displays an interference screen based on a calculation result in the interference evaluation unit. The interference evaluation unit 21 specifies the section of the state for each state of the work area to be used based on the area division data stored in the work content information storage unit 12.

  In the case of the area segment data that is the input information shown in FIGS. 8 and 9, it changes in six types of states. Moreover, the interference location is displayed on the fourth interference screen shown in FIG.

  That is, in the period from 2015/04/09 00:00 to 2015/04/12 23:59, the area section Q002 used in the work of the work name B3 shown in FIG. 8 and the work of the work name C2 are performed. The result is that the area section R001 used for the interference is derived. Based on this result, for example, adjustment is made between a person who has management responsibility for the work name B3 (work manager) and a work manager of the work name C2. Here, the person in charge of the work constitutes a construction-related line under the local director. For example, in the case of construction work, the construction chief who constitutes the line under the deputy director in charge of the construction, or divides it. For example, a work manager. The adjustment includes a review of the process or a review of the area section used in the work. Alternatively, it may be based on another adjustment rule at the time of interference.

  Next, as shown in FIG. 2, the next day work is input (step S30). The input of the next day's work is in principle performed by the work manager who is responsible for work management. However, the work manager may determine the contents and instruct a physical input work, but the work manager is responsible for the input contents. The next day work schedule data which is the contents of the inputted next day work is stored in the work content information storage unit 12. If the same work content continues for a plurality of days and it is allowed as a rule to input this period all together, a plurality of days are input as the current work.

  FIG. 11 is a table showing an example of next day work schedule data used in the construction management system. The next day work schedule data includes the work name of the next day, the work area, the work content, the priority management work flag, and the work team name for each work name. The priority management work flags are dangerous goods, fire, heavy goods, and high places / openings. Hazardous material handling work, fire handling work such as welding, heavy work handling heavy goods handling, heavy work handling work, working at high places or around the opening. In the priority management work flag column, “0” indicates that there is no corresponding work, and “1” indicates that there is a corresponding work.

  As for the work area, for example, as in the example shown in FIG. 9, the area section may be designated on the screen by tracing the necessary area with a touch pen, for example. The designated area number may be used as the input of the work area portion of FIG.

  For example, the work names of work items scheduled for April 8, 20XX, which is the next day, are A2, B2, and C2. For example, in the case of work name A2, the work content is XXX01, the item of the priority management work flag corresponds to heavy material handling work, and the work team name is X1.

  Next, as shown in FIG. 2, the risk evaluation unit 22 calculates the risk level related to the work content and work environment (step S40). FIG. 12 is a flowchart showing a detailed procedure of risk calculation related to work content and work environment by the risk evaluation unit of the construction management system according to the first embodiment.

  The detailed procedure for calculating the risk level related to the work contents and work environment in step S40, which is performed after the input of the next day work in step S30, is as follows.

  First, the risk evaluation unit 22 sets the risk degree RF1 related to the work content and work environment to 0 (step S41). Next, the risk evaluation unit 22 determines whether there is a hazardous material handling operation (step S42). If it is determined that there is a hazardous material handling operation (YES in step S42), the first risk degree RF11 = C11 is set (step S43). If it is determined that there is no dangerous goods handling work (NO in step S42), the first risk degree RF11 = 0 is set (step S44).

  Next, the risk evaluation unit 22 determines whether there is a hot work (step S45). When it is determined that there is a fire work (YES in step S45), the second risk degree RF12 = C12 is set (step S46). Moreover, when it determines with there being no hot work (step S45 NO), it is set as 2nd risk degree RF12 = 0 (step S47).

  Next, the risk evaluation unit 22 determines whether there is heavy material handling work (step S48). If it is determined that there is a heavy load handling operation (step S48 YES), the third risk degree RF13 = C13 is set (step S49). If it is determined that there is no heavy load handling operation (NO in step S48), the third risk degree RF13 = 0 is set (step S50).

  Next, the risk evaluation unit 22 determines whether there is work around the high place / opening (step S51). If it is determined that there is work around the high place / opening (step S51 YES), the fourth risk degree RF14 = C14 is set (step S52). If it is determined that there is no work around the high place / opening (step S51 NO), the fourth risk degree RF14 = 0 is set (step S53).

  The specific values of the risk values C11 to C14 set by the risk evaluation unit 22 as the first risk degree RF11 to the fourth risk degree RF14 are dangerous goods handling work, fire handling work, heavy goods handling work. In addition, it can be determined in advance according to the contents of each priority management work such as an aerial work or work performed around the opening, and can be stored in the risk evaluation unit 22, and the risk values C11 to C14, etc. A risk value setting database may be provided, and the risk evaluation unit 22 may perform evaluation while referring to the risk value setting database.

  Next, the risk evaluation unit 22 calculates the risk level RF1 related to the work content and work environment as the sum of RF11, RF12, RF13, and RF14 (step S54).

  FIG. 13 is a table showing the result of risk calculation by the risk evaluation unit. Information on the risk level R is added to the information on the next day work in FIG. Here, the risk degree R is the value of the risk degree RF1 related to the work content and work environment calculated by the risk evaluation unit 22 for each work. As a result, it is possible to grasp what kind of work is performed in which work and the degree of each risk R.

  The risk level R calculated by the risk evaluation unit 22 is output from an output unit (not shown) of the arithmetic unit 20 together with information such as a work area (area section), a work content and a flag relating to priority management work, and stored in the risk level storage unit 17. Is done. At this time, the arithmetic unit 20 can output the calculation result as a risk map. In this case, the risk degree storage unit 17 may be configured to store the output risk map.

  Next, as shown in FIG. 2, display by the output display device 40 is performed based on the result of the above calculation or the like output from the calculation device 20 (step S <b> 80). The display by the output display device 40 can be displayed in the same format as the interference screen shown in FIG.

  In other words, on the map of the construction area (site) of the target construction, the area sections of the work to be performed in the set period are displayed, together with necessary work information such as construction name and work items in the displayed area section The risk degree R calculated by the risk evaluation unit 22 is displayed. At this time, the risk degree R may be expressed by changing the display color of the area section of each work in accordance with the risk degree R, in addition to displaying specific numerical values and indicators such as high, middle and low as characters.

  In this way, the risk level R for each area section of the construction target area is displayed on the map, so that the parties can easily grasp and share information on the high-risk work performed in which area section during the set period. It becomes possible. As a result, it is possible to suppress the occurrence of disasters, quality nonconformities, etc. in construction management.

  The information displayed by the output display device 40 uses information stored in the risk degree storage unit 17 in advance, as well as using the risk map stored in the risk degree storage unit 17. You may use as it is. Or what was calculated by the output part of the arithmetic unit 20 anew based on the risk degree R memorize | stored in the risk memory | storage part 17, the work information memorize | stored in the work content information storage part 12, etc. may be used.

  FIG. 14 is a block diagram for explaining an output display method of the construction management system and a configuration related thereto. The output display device 40 includes worker position receivers / transmitters 41 and 42, a determination unit 45, and a display unit 46.

  There are a plurality of worker position receivers / transmitters 41, and each worker carries each one. The worker position receiver / transmitter 42 is carried by the person in charge of work at the site or the work manager. The worker position receiver / transmitter 41 outputs the worker's position information to the worker position receiver / transmitter 42 and can perform normal two-way calls. In addition, the worker position receiving / transmitting device 42 receives the worker's position information from each worker position receiving / transmitting device 41 and can make a two-way call.

  The determination unit 45 refers to the information about the work area such as the risk map and the risk degree stored in the risk degree storage unit 17 and the information such as the type of flag relating to the priority management work, and the current position of the worker is It is in an area related to work with a high degree of risk, and it is determined whether or not work corresponding to priority management work is being performed.

  When the determination unit 45 determines that a certain worker is performing work corresponding to the priority management work in an area with high risk, the display unit 46 displays the fact.

  The display unit 46 can also be used to carry out risk prevention activities in a timely manner by carrying it as a wearable terminal, for example, by a person in charge of work at the site or a work manager.

  As described above, in the first embodiment, the interference evaluation unit 21 checks the presence / absence of interference in the work area and displays the location and period of interference in the preliminary stage. is there.

  When the next day work schedule data is input, the risk evaluation unit 22 calculates the risk level RF1 related to the work content and work environment for each work, and can grasp the degree of risk and the cause of the risk. In addition to ensuring thorough attention, the output display device 40 can call attention on the spot.

[Second Embodiment]
FIG. 15 is a block diagram illustrating a configuration of a construction management system according to the second embodiment. This embodiment is a modification of the first embodiment. In the second embodiment, the storage device 10 further includes a worker skill information storage unit 13 and an instructor skill information storage unit 14.

  In this embodiment, although the memory | storage device 10 demonstrates to the example which has both the worker skill information storage part 13 and the instructor skill information storage part 14, an operator skill information storage part 13 and an instructor skill information storage part are demonstrated. A configuration having only any one of 14 or a configuration in which both are combined into one may be used.

  Here, a worker is a member who is registered and managed as a local resident member at a local construction site or work site related to the plant. An instructor is not a resident member but a member dispatched from a factory, who specializes in guidance on adjustment / testing of specific equipment, installation, etc.

  FIG. 16 is a table showing an example of work member data stored in the worker skill information storage unit of the construction management system according to the second embodiment. The target work is the next day work input in step S30. The three columns indicate whether or not the work group, members, and conductor are applicable. For example, from the first line to the second line of data, regarding the work team GA1, the members are WA and WC, respectively, and the WA is the conductor. Similarly, the third and fourth lines of data indicate that for work team GB1, the members are WB and WF, respectively, and WB is the conductor, and the fifth and sixth lines of data are Regarding the work group GC1, the members are WD and IB, respectively, and WD is the conductor.

  FIG. 17 is a table showing an example of worker skill data which is worker skill information stored in the worker skill information storage unit of the construction management system according to the second embodiment.

  Each row in the table of FIG. 17 is the years of experience data related to each member of the worker skill data shown in FIG. This data is for all workers involved in the work of the plant. Therefore, for example, in the case of work group GA1, regarding the next day work shown in FIG. 16, the members are WA and WC, but the registered members shown in FIG. 17 include, for example, WE.

  The years of experience data shown in FIG. 17 is the years of experience for each object. The objects are specifically pumps, valves, electric motors, process instrumentation, and others. The years of experience for each are stored as data, and the last column is the sum of these years of experience.

  For example, member WA has 2 years of experience for pumps and 1 year for valves, for a total of 3 years. Further, for example, the member WC has a content of 2 years for the pump, 3 years for the valve, 5 years for the others, and a total of 10 years.

  Although not shown, the instructor skill information storage unit 14 stores similar data about the instructor, that is, instructor skill information.

  FIG. 18 is a table showing an example of non-resident skill data stored in the non-resident skill information storage unit of the construction management system according to the second embodiment. Each row is data for each non-resident. Each column is non-resident, work, start date and end date. Here, the non-resident is a first-time visitor as described above. For example, the non-resident is a designer or the like, for example, a person who enters the site for the purpose of confirming the performance of the designed equipment or investigating the cause of the malfunction.

  For example, the non-resident DA indicates that the operation B2 is performed on the site in the plant during the period from April 5, 20XX to April 10, 20XX, and performs the intended action regarding the work B2.

  FIG. 19 is a flowchart showing a procedure of the construction management method according to the second embodiment. In the present embodiment, step S50 is further added to the procedure in the first embodiment.

  That is, in step S40, the risk level related to the work content and the work environment is calculated. In step S50, the risk level related to the work related person is calculated. Specifically, the degree of risk due to workers, instructors and non-residents is calculated.

  FIG. 20 is a flowchart showing a detailed procedure for calculating the degree of risk related to a work-related person by the risk evaluation unit. Hereinafter, the detailed procedure of step S50 of the risk degree calculation which concerns on the work related person by a risk evaluation part is demonstrated.

  First, the risk evaluation unit 22 sets the risk level RF21 related to the worker, the risk level RF22 related to the instructor, and the risk level RF23 related to the non-resident to zero (step S51).

  Next, the risk evaluation unit 22 sequentially reads the skill data of workers engaged in the next day work from the work member data and work member skill data related to the next day work stored in the worker skill information storage unit 13 (step S52).

  The risk evaluation unit 22 determines whether or not the worker's years of experience X for the target work is less than the threshold C21 from the read skill data of the worker (step S53). Here, the threshold value C21 is set based on the number of years in which the risk due to lack of experience is almost eliminated.

When it is determined that the number of years of experience X is less than the threshold C21 (YES in step S53), the risk evaluation unit 22 calculates the risk degree RF21 related to the worker by the following equation (1) (step S54).
RF21 = RF21 + K21 * (C21-X) (1)

  Here, K21 is a weighting factor, taking into account the relationship between the weight C11, C12, C13 and C14 in the risk level related to the work content and work environment, the risk level RF22 related to the instructor, and the risk level RF23 related to the non-resident. Set.

  Moreover, when it determines with it being more than threshold value C21 (step S53 NO), the risk-evaluation part 22 leaves the risk degree RF21 which concerns on a working member as a last time value (step S55).

  Next, the risk evaluation unit 22 determines whether or not the evaluation has been completed for all the work members involved in the next day work (step S56). When the risk evaluation unit 22 does not determine that the evaluation for all members has been completed (NO in step S56), the risk evaluation unit 22 repeats step S52 and subsequent steps.

  When it is determined that the risk evaluation unit 22 has completed the evaluation for all members (step S56 YES), the risk level evaluation for the worker is ended and the risk level evaluation for the instructor is performed.

  The risk evaluation unit 22 sequentially reads the skill data of the instructor engaged in the next day work from the instructor skill data related to the next day work stored in the instructor skill information storage unit 14 (step S57).

  The risk evaluation unit 22 determines whether or not the instructor's years of experience Y is less than the threshold C22 for the target work from the read instructor's skill data (step S58). Here, the threshold value C22 is set on the basis of the number of years that the risk due to lack of experience is almost eliminated.

When it is determined that the years of experience Y are less than the threshold value C22 (YES in step S58), the risk evaluation unit 22 calculates the risk degree RF22 related to the instructor according to the following equation (2) (step S59).
RF22 = RF22 + K22 * (C22-Y) (2)

  Here, K22 is a weighting coefficient, and is set in consideration of the relationship with other risk levels, similarly to K21.

  Moreover, when it determines with more than threshold value C22 (step S58 NO), the risk evaluation part 22 leaves risk level RF22 which concerns on a working member as a last time value (step S60).

  Next, the risk evaluation unit 22 determines whether the evaluation for all the instructors related to the next day's work has been completed (step S61). If the risk evaluation unit 22 does not determine that the evaluation for all members has been completed (NO in step S61), the risk evaluation unit 22 repeats step S57 and subsequent steps.

  When it is determined that the risk evaluation unit 22 has finished the evaluation of all the instructors involved in the next day's work (step S61 YES), the risk degree evaluation related to the instructor is completed, and the risk evaluation unit 22 Risk level evaluation is performed (step S62).

  For non-residents, there are various situations for the purpose of entering the site and the actions at the site when entering the site. For this reason, the risk level related to non-residents is determined by taking into account the risk level R1 related to the work content and work environment, the risk level R21 related to the worker, and the risk level R22 related to the instructor. Set. This value is input when the next day work data is input in step S30.

  Next, the risk evaluation unit 22 calculates the risk degree R2 related to the work-related person by R2 = R21 + R22 + R23. Further, the risk degree R is calculated by R = R1 + R2 (step S63).

As described above, in the present embodiment, the work content and work environment related to the next day work.
In addition to the risk level due to the risk, the risk level due to workers, instructors and non-residents can be further evaluated.

Each row is arranged in order of nonconformance numbers. Since new data is added each time it occurs, the order of non-conformance numbers is the order entered and registered in the non-conformance case information storage unit 15.

  Each column includes a nonconformance number, a system number, an occurrence date, an occurrence location, nonconformity content, a cause, and a work keyword.

  Note that the information on the nonconformance cases may not be unique to the construction management system. That is, you may use the database regarding the nonconformity information maintained as part of a quality assurance system.

  FIG. 23 is a flowchart showing a procedure of the construction management method according to the third embodiment. In the present embodiment, after calculating the risk level related to the person involved in the work in step S50, the nonconformity case related to the next day work or the current work is confirmed (step S70).

  Confirmation of nonconformities is done in two steps.

  First, the non-conforming case evaluation unit 23 extracts related non-conformances from non-conforming case information stored in the non-conforming case information storage unit 15 based on the next day work contents input by the work manager and stored in the storage device 10. To do. Extraction is performed based on the presence or absence of a combination of the presence / absence of the work keyword of the priority management work item. For example, the place of occurrence, system, etc. may be added as keywords.

  FIG. 24 is a table showing examples of nonconforming cases extracted as a result of confirmation of nonconforming cases. Each line is work the next day. Each column is the work name, priority management work item, and nonconformance case. The priority management work items are further classified into keywords such as dangerous goods, fire, heavy objects, high places / openings, and others. Non-conformance cases are non-conformance number, nonconformity content, and cause.

  Next, the work manager looks through the extracted non-conformance cases, and further extracts non-conformance cases that are considered to be beneficial to be transmitted to the worker in view of the contents of the work the next day. This final non-conformance case will be introduced at the morning meeting in the office and the risk prediction confirmation at the toolbox meeting at the site to thoroughly prevent the occurrence of non-conformity.

  As described above, information on nonconformity cases can be used effectively.
