11. Subcontracting contract: Contract for subcontracting by subcontractors

12. EVM: Analytical Method of Performance vs. Plan of Construction Process / Cost in North America (U.S.A.)

13. Material for payment: Material that constitutes the facilities of the Corporation and materials paid by the project operator.

14. Subsidiary Materials: Materials that make up the facilities of this construction, purchased by construction contractors.

15. Provisional materials: Materials that are temporarily installed for work and removed and reused after work is completed.

The core tasks in carrying out construction work include not only schedule management and quality / safety management of each operation, but also input resources such as accounting management according to billing, receipt, and payment of subcontracting, subcontracting, and direct construction costs, and materials, labor, and medium-term. Accounting management, contract change management of subcontracting and subcontracting, etc. shall be carried out in accordance with contract, record of use and payment of expenses.

The management tasks of each field have their own work areas, but the work progress is at the center of construction management because the work is generated from the process of planning and executing the construction work for each stage of construction. This is the main reason for managing the construction by establishing a schedule management plan for the entire construction before commencement of construction.

In general, the schedule management of a construction project is a technique that classifies and defines the construction details for the construction contract as activities to be actually implemented, and manages the defined tasks to achieve a given goal within a given period of time. It refers to the schedule management of / CPM technique, and a lot of commercial packages that support such schedule management are being developed and spread.

Most construction schedule management systems only manage the schedule information of construction work, the relationship information between each work, and the information on the quantity of resources planned for the construction work. Plan and results of quality and safety management work, log generation and storage of accounting work including construction work, management documents such as materials, personnel, construction machinery, etc. The ability to create and manage them is not included.

Attached Figure 2 is a graphical user interface of most calendar programs currently in use.

The main weakness of such a schedule program is that it is difficult for the construction participants to have a common awareness of the names of the activities and the scope of their tasks.

Even users skilled in the use of schedule management programs do not have sufficient understanding (common perception) of the work breakdown structure, the name of the activity, and the scope of work of each work. It is not easy to grasp the status

That is, only the user who has composed the classification system so that the details of the construction can be entered into the schedule program and planned the promotion schedule or the user who has been familiar with the construction details and the promotion plan through long-term intensive use can enter the system. It also means that data from the system can be interpreted and processed.

Although it is difficult for all the users to fully understand the above work name and task range, it is practically difficult for all the users to learn and cope with it again when the work name is changed due to a design change or a plan change.

In addition, most construction work is not only for the user who manages the site but also manages a large number of construction work in the head office, so the user interface that defines the work name and scope of work by the current letter or icon There is a limit to this problem, and this is the main cause that hinders the informatization of construction management.

In addition to the schedule management, the core management tasks in carrying out the construction work include accounting management, design change management, quality control, safety management, labor management, material management, and medium-term management of subcontracting / subcontracting / directed construction costs. The tasks in each field have their own work areas, so even if the person in charge is separated or not, the work performance results and outputs must be classified and preserved separately.

Therefore, the construction managers in the construction site rely on individual manual work in performing the management tasks for each field that should be performed in the actual construction management work, or perform tasks in separate systems for each field even by using a computer.

In addition, the documents and drawings calculated as a result of the performance of the work is being managed and printed or stored in a hard copy of paper documents, CDs, or using a separate document / drawing management system.

The following is the method of performing the construction management work by field, which is being implemented at the construction site.

Figure 3a. Shows the process of grasping the daily work status, the task of managing the work schedule (Schedule) and the quantitative grasp of the construction status. The work status and report is orally communicated by the person in charge at the place of work and reports it to the payment right holder at the end of the daily work. Most of the work schedule management is to read the paper documents output from the schedule management program and share the schedule information by construction related person. There are very few cases in which the schedule management program can be displayed on the respective computer terminals. In addition, in order to grasp the quantitative construction status, there is a process of investigating the progress of each work type and counting and counting the quantity by progress. In this process, the utilization of the computer is the benefit of simple calculation using a spreadsheet such as Excel.

Figure 3b. Shows the process of changing the subcontracting contract and the billing process of the contractor during the contract management work between the contractor and the contractor who received the construction contract. The process of changing a contract is not the same as writing a statement of change in a spreadsheet, and the process of change is manual.

3c. Shows the construction contractor of the construction work for the budget change and the on-site billing process for the actual input cost. The process of preparing the change budget is a manual calculation, and the actual input amount and the on-site billing process are also done manually. The process is to use intranet payment of paper documents or spreadsheets.

Figure 3d shows the process of the construction contractor managing the subcontract, and the process of calculating and paying the subcontracting period as well as the subcontracting change is similar to the contract of quantity calculation by manual labor and distribution and preservation of documents by paper documents. In this process, the use of a computer is in the process of creating and archiving documents by spreadsheets.

Figure 3e. Is a process of managing the delivery of the material brought into the site, the receipt of the material to the receipt of the invoice or receipt of the goods receipt by filling out the processing and receipt, that is, the usage is confirmed by the issuer to issue the goods receipt or inventory check It is confirmed and managed by. Mostly by hand.

Figure 3f. Shows the process of labor management, which is the most computerized field as of June 2005, but the method is to check the service status by paying the ID card to individual workers and checking the service status by the card. It is not possible to link the service status with the calculation of actual input costs and billing.

Figure 3g. Shows the process of the management of the medium-term (construction machinery) put into the site, and all of the medium-term lease contracts, use time counting and payment of the medium-term fees are all processed manually.

Figure 3h. Shows the process of the expenditure on the expense expenditures in the field, and may use a computerized book, but this book is not related to the actual input cost calculation or billing of the whole construction.

Fig. 3i shows that the preparation / submission of construction plan, machine production approval book, and material supply source approval personnel, which are quality control services at the construction site, is carried out separately from the inspection and testing. The quality control work should be planned based on the schedule, as it should be planned in connection with the construction schedule and process. At present, this quality control plan is carried out not only by separate tasks by manual personnel but also by all paper procedures.

Figure 3j. Shows the general implementation of the safety management work at the construction site. Overall safety management, safety training, and safety inspections are not only dependent on paper documents, but are also performed independently of each other, without regard to schedules or process plans.

The characteristics and problems of the conventional construction management methods discussed above can be expressed as follows.

First, even when planning the informatization of construction management using a schedule management program, common recognition of the name and scope of each task included in the construction is not easy.

Second, the grasp of work progress on the site can only be delivered by paper documents or verbally, and there is a temporal and spatial limitation in the sharing of information among construction personnel.

Third, each field of construction management cannot be managed in connection with each other, but is carried out separately.

Fourth, even if there is a settlement column in the paper document, the work process may not be systematic, and if a certain time passes even if the work is not executed or is abnormally executed due to the intention or mistake of the person in charge, it is difficult to grasp it. In addition, the process of creating the achievements generated by each task is performed by hand, and the continuity of work is difficult when the staff is replaced due to preservation by paper documents.

The present invention has been proposed in order to solve the above-mentioned conventional problems, the object of which is as follows.

-Provide a common language for the structure and scope of work

The project history can be managed through a graphical user interface that is designed for the purpose of the construction project, providing users with a visual common language for the work, making it easier for users to organize the construction history and the scope of the work. How to pass

-Real time construction status

The construction status and construction management status of the construction work can be entered through the work breakdown structure and the terminal of the person in charge of management by the terminal, and can be displayed as the current work status, thereby quantitative information according to the current progress of the construction as well as today's work. Provides in real time.

-Integrated management and task automation of construction management work

By setting the work classification system (WBS) as the activity unit of the schedule management program and associating the construction management items with the schedule management program, information of all areas of construction management can be integrated and managed. Progress progress input facilitates integrated management of construction management by updating the work schedule as well as the performance of each management field. In addition, the linkage of all the tasks due to the integrated database allows the construction records of each management field to be automatically generated and preserved.

-Provision and preservation of work performance records and management ledgers with clear responsibilities and authorities

The authority and responsibilities of each person in charge are specified by ensuring that the construction management status database, including daily performance updates, established (contract, subcontract, and management) and quality / safety management plans and performance checks, can be updated through the approval stage within the organization. Keeping records of the process ensures the continuity of work as well as the audit of results and the replacement of personnel.

The data for each management field of construction have characteristics that data is generated and processed according to the progress of work centered on activity.

According to the characteristics of the construction work, the construction management technique that establishes, executes and monitors the construction plan by setting the activity to measure the progress of construction and quantifying the progress of the construction is a project management developed around the US construction field. It is well known in Korea as a technique.

The process of deriving the activity is divided into facilities or zones that meet the management objectives by applying a technique called a work breakdown structure (WBS). Classify as) Commodity is again classified into activities to organize the details of the entire construction into a collection of hierarchical elements. This technique is the basis for establishing a schedule and performance management system (EVMS) in the form of PERT / CPM, enabling resource allocation and performance accounting for each task. 4 shows the general structure of the WBS.

The basic structure of this construction status information integrated management database consists of a work breakdown structure (WBS) to distinguish the details of the construction work, as shown in Figure 2. Each work has a schedule such as work period and work order The progress schedule of each schedule management program file can be updated by configuring and connecting the input schedule management program into files for each management field and configuring a separate input window (working daily report) for input (update) of work progress. At the same time, the record of the input window can be preserved.

To this end, subcontracting cost, execution budget, subcontracting, material, quality control and safety management items are assigned to each activity of the schedule management program as resources, and the process is updated by updating the progress of the construction schedule. The progress, subcontracting, and actual cost of construction cost, quality management performance, and safety management performance can be updated, so that the progress and management status of the construction can be provided in real time.

In addition, it provides the status of billing and receipt of contracting, funding and subcontracting for construction management, which is calculated from the above basic functions, and supports the original data change process such as design change, contract change, and record keeping. In addition, the user's convenience for writing work schedules can be prepared by creating a quality control characteristic factor map from the work schedule of the schedule management program, and the function to display the results of each task and the safety management plan to be displayed for each facility. Support.

In addition, by setting up customizing and approval process for each management field, it is possible to confirm, record, and preserve daily inputs and log.

For the implementation of such a function as shown in Figure 1. Construction status module, subcontracting module, execution budget module, subcontracting module, material management module, labor management module, medium-term management module, field security status module, quality control module, Set up modules for each management field as safety management modules, and each module should be configured to have subordinate details such as construction cost details, resource details, and management work details.

The hierarchical structure of the WBS, which is the basis of the database, is organized into visual shapes and task-specific flowcharts to facilitate the input and current status of unit types.

The composition and operation of each module is as follows.

end. Construction Status

As shown in Fig. 6, the construction status management module defines the construction scope for each work according to the work breakdown structure (WBS), and records the performance input and input procedures (electronic approval, etc.) on the progress and task performance results of each work. It has the function of managing and storing / retrieving the result after payment. In addition, the summary / chart / The results are compared to the plan due to the detailed status. It also has the function of determining the settlement procedure of performance input and the method of calculating actual input cost according to direct management, subcontracting, and direct and subcontracting.

Construction Outline

As described above, the data for each management field of the construction work has the characteristic that data is generated and processed according to the progress of the work based on the activity.

Activities derived from constructing WBS can only be expressed in letters or numbers as shown in FIG. 2. There is a limitation that these expressions are transmitted to all the participants in the same meaning. In other words, the names of the elements of each hierarchy of the WBS make it difficult to derive a common understanding among users about the scope of work and work methods.

In order to solve this problem, users can easily understand the composition of the WBS by using the user interface that expresses the WBS in construction, after construction, or in a combination of both. Organize by sharing information about definition, work order and construction method.

As shown in FIG. 5, the hierarchical structure of the work breakdown structure (WBS) is described as a submenu with a step-by-step description.

The method of expressing the WBS consists of the main user interface with the WBS, which consists of the parts corresponding to the facilities or zones in the shape of the finished product, and designates the objects that shape each facility or zone. If it is set to be connected with a component and designates a specific part that means the outer part of the object or the whole construction, this means selecting the whole construction or the top level.

In the case of designating a part corresponding to each facility or a designated area, indicate the independent type of the facility, which is the first level (Level-1) of the WBS, and the relationship with the works or parts of the plant below it. It is manifested as a level-2 user interface (two-level menu), and when the work or facility part is designated on the two-level user interface (two-level menu), the work or subordinate works of the subordinate work are related to the work order and connection. It is represented by a three-level user interface (three-level menu). Selecting a particular item on each user interface (each menu) links to the corresponding element of the WBS. The level setting of the user interface can be increased or decreased depending on the number of levels of the WBS. Each menu may be zoomed in or out.

In summary, the construction outline 20102 of FIG. 6 is a component of the work breakdown structure (WBS), that is, the data of the activity description, and includes data such as the scope of work, work method, work condition, work specification, and image of the work. It is an index that designates the data corresponding to the scope of the work in the data table of each menu as a step of the user interface for retrieving the details of a specific work among all construction details.
