Such value engineering (VE) is an effective means to reduce costs, improve productivity and improve quality. It can be used to obtain the same function at a lower cost, to improve and increase the function at the same cost, And develop alternatives to eliminate costs and optimize operational costs or revenues.

In Korea, such value engineering (VE) techniques are introduced mainly to large corporations and applied to quality or production management innovation, and are mainly used for analysis of design alternatives and construction process analysis of construction companies.

Currently, we use value engineering (VE) techniques in construction industry and various business fields at home and abroad to analyze various comparison proposals and utilize them as decision making tools. For example, in evaluating the value of an object, there are quantitative values that can be evaluated numerically, and there are more qualitative elements that are visible but not easily expressed in numerical value. Engineering (VE) analysis is a qualitative part, but it supports quantification and quantification of many important parts of decision making.

If there is no satisfactory result in the idea evaluation step S24 and the alternative development and evaluation step S25, the process returns to the idea creation step S23.

The execution step S30 is a step for performing execution and follow-up, and when execution and subsequent actions are difficult to perform, the process returns to the preparation step S10 described above.

However, there are few computerized systems considering factors that can be quantified by stages of value engineering (VE) and detailed step - by - step interconnection. Therefore, it is a reality that various comparative analysis results are not systematically derived through numerical and visualization at various stages. In addition, there are problems in that it takes much time to numerically calculate correction items in the value engineering (VE) step performed by a large number of team approaches, thereby delaying decision making.

BIM (Building Information Modeling) is a three-dimensional construction information management process used throughout the life cycle from the planning stage to the maintenance stage of the three-dimensional shape and information of construction facilities.

Specifically, BIM refers to the process of modeling a facility in a virtual space such as planning, design, engineering (structure, facility, electricity, etc.), construction, further maintenance and disposal in a multidimensional virtual space. In particular, it enables the design and construction of low-cost buildings with cutting-edge design and environment-friendly energy, which is a recent issue, and is a similar concept to the multi-dimensional virtual design construction (VDC). In recent years, the application of BIM has been widely used in civil and plant fields in Europe and the US because it covers all construction environments as well as construction environments.

On the other hand, a construction project includes a series of stages from business planning to design, construction and maintenance. In each stage, various specialized fields such as architecture, civil engineering, facilities, electricity, and communication are involved. These specialized fields generate, modify and transmit various construction information in each project, and these construction information are shared and integrated according to the correlation of work between specialist fields.

In terms of computerization of such construction information, the domestic and overseas construction market is rapidly shifting from 2D CAD to 3D CAD and BIM environment to integrate information of the entire lifecycle of the building. This BIM technology enables to store and utilize various building information during the whole life cycle of the building, and it can increase the efficiency of the construction project by providing an environment that can manage the geometric shape information and property information, Reduce project costs, and increase profitability due to shortening of time.

This BIM is a medium of information transfer, and it can improve the efficiency of construction management by helping to understand complex information of many fields by storing and processing information generated from construction management. Process and cost information is more frequently used compared to other information, which has a great influence on the efficient and effective execution of construction work. Therefore, information is analyzed and utilized in various ways such as 4D (3D + Time) or 5D (4D + Cost) simulation by linking process / cost information based on the shape information of BIM. However, Has failed to meet the expectations of the industry. Currently, there are the following problems in the field of BIM-based process and cost information management.

First, the object-oriented information structure of BIM is disadvantageous for processing information required for process management, cost management, and initial management based on work. In addition, the process of generating and using process and cost information based on BIM-based is incompatible with the construction management work process in practice, which leads to an increase in the work load due to input of process and cost information.

In addition, BIM can not obtain necessary information through BIM, and BIM is not actively utilized in construction management. This is because most BIM software analyzes process and cost information based on process and cost information generated based on the modeled object. At this time, since the information to be generated is limited, identification of process and cost information other than object- And analysis functions are insufficient.

Also, in the field of construction project, the purpose of integrated management of process cost is to predict the construction cost and completion date quickly and accurately, and to build a database for the future project by recognizing the progress of the construction based on the quantity used for the work However, in the domestic construction industry, cost - oriented process control using the statements has been done during the period. The statement is composed of the item information and cost information required for the construction based on the design drawings. The detail data generated in the statement making process is not delivered after the statement is made, but the work is carried out only by the statement .

In this way, it is difficult to know what kind of work is done in the field because of the cost of judging the construction progress as the construction cost of the statement. In addition, it is difficult to systematically organize the results of the project and use it as a database for new business by expressing and managing the work as the cost.

In recent years, some attempts have been made to apply some of the above-mentioned BIMs in order to provide accurate information quickly and easily in the design VE business, and to simplify the VE procedure. However, the VE service which can be applied to BIM is partially introduced.

Meanwhile, FIG. 4 is a diagram illustrating a BIM model design book prepared by a BIM tool according to the related art, to be delivered to a client.

4, the BIM model design book 72 prepared by the BIM tool 71 according to the prior art is delivered to the ordering client 73. At this time, the BIM model design book 72 is separately provided And is delivered in a state created by the BIM tool 71 without being processed.

However, according to the conventional technology, there is a shortage of infrastructure such as cost management (CM), classification standard, and construction cost data in the design stage. In addition, proper quality is secured within a limited budget within a predetermined time, It is necessary to design and manage it. At this time, it does not satisfy the buyer's interests such as business expense risk, design adequacy, and schedule management risk.
