Description

Construction Engineering Support Information Processing Method and System {Value Engineering System and Method on the Same}

The present invention relates to a method and a system for supporting construction VE support information, and more specifically, construction VE support information processing method capable of immediately supporting precise VE by generating construction cost-specific cost breakdown information for each construction item and its construction cost. It is about the system.

Value Engineering (VE) is a general concept, as Lawrence D.Miles advocates, so that the customer who buys a product buys the product's functionality, so that the ability to obtain that functionality with available materials, equipment, and personnel It's based on what you can offer. In other words, in the creation and development of alternatives, product-oriented tangible thinking is transformed into functional-oriented intangible thinking, and the concept of function is gradually expanded and redefined as a concept of value. VE is defined as "organizational effort to analyze the function of a product or service to ensure that it achieves the required function at the lowest life cycle cost."

Construction workers have often mistaken VE for simple design reviews or cost savings. Of course, it is true that VE will result in cost savings, but since the function-based verification seeks a proper balance between time, performance, and cost, the VE proposed alternative is the Optimal Solution, the Best Solution. Can). Therefore, it is no exaggeration to say that cost reduction through VE is a technique by which experts in various fields find and remove unnecessary functions through team approach, and the success or failure of VE depends on how to define and analyze functions. The conventional cost reduction method tried to reduce the cost of each component according to the subject of the project. However, in the VE applied method, the function is classified to maintain the basic function and the required secondary function, but the unnecessary function is removed and the function of the design concept is eliminated. It is a way to enhance the value of a product or project by constructing another alternative.

By defining, arranging and analyzing the functions of the product or facility in detail, VE eliminates unnecessary functions and maintains designers' ideas while maintaining the main functions, the secondary functions, legal and institutional functions, and the functions required by customers. It aims to suggest alternatives by developing creative ideas for the function by Thus, VE is the most compelling alternative to other creative approaches to finding improvements, focusing on the need for functionality rather than ignoring or finding fault with existing designs, products, orders and systems.

In the era of global standard, where the distribution structure is being simplified with the development of science and technology, the world cannot survive unless it continuously increases sales in infinite competition as a single market. Thus, the need for VE is even more urgent as it faces a situation where cost savings must be made not only in hardware, including production facilities, but also in software components, including distribution means. VE is applicable to all fields, and the user-centered and functional-oriented approach is the basis of thinking through the change of ideas.

Domestic Design Ve System 1.1. Enforcement Decree of the Construction Technology Management Act In 2003, the Ministry of Land, Transport and Maritime Affairs newly established 15 articles (Articles 30 to 28, 2006) from Article 38-4 to Article 39-19 of the Enforcement Decree of the Construction Technology Management Act. It aims to reduce the side effects of budget waste and subcontracting, improve the consciousness of the people who participate in the construction process, and enhance the efficiency of public construction projects by strengthening follow-up management. In Article 38-13, the basic design and final design of the construction work with construction cost over 10 billion won, the economic feasibility and the feasibility of applying the site by the main functions of the design target facilities (hereinafter referred to as "economic design") Or design experts such as design supervisors under Article 22 of the Act.

Definition of VE Projects The legislation revised in 2005 stipulates the economic and economic considerations of basic and final designs for construction projects with a total construction cost of over 10 billion won. In addition, the VE Proposal Revision Regulation Ordering Office is required to reflect the contents of the proposal through the "Review of the economic feasibility of the design" to the design content, but the application of the proposal content is technically difficult or excessive cost increase is required. It states that it can be excluded. 1.1.3. VE analysis policy The requirements for the timing, frequency, consideration criteria, and specific review methods and procedures of the "review of economics, etc." of the design shall be in accordance with the guidelines for reviewing the economics, etc. of the design. It must be submitted to. 1.2. Review of economic feasibility, etc. Enforcement Guidelines The Ministry of Land, Transport and Maritime Affairs, through the provisions of Article 3813 of the Enforcement Decree of the Construction Technology Management Act, will carry out design VE execution procedures and work contents for the purpose of budget reduction, functional improvement, structural safety, and quality assurance of public construction projects. A detailed implementation guideline on the review of the economic feasibility of the design (hereinafter referred to as the guideline) was established and published.

On the other hand, technology development compensation system similar to the US construction VE system (VECP) has been implemented in Korea for a long time. The technology development compensation system uses new technologies and construction methods (including functions and functions equivalent to those of government design, equipment, equipment, etc.) applied by the contract partner to reduce construction costs and shorten the construction period. It is being implemented to inspire development and increase international competitiveness. According to the "Presentation on the Case of Budget Reductions in the Construction Industry" held in December 1999, the Ministry of Construction and Transportation's budget was an example of savings in the budget of KRW 62.7 billion through changes in construction methods and improvement of construction methods. The average savings were about 29.8 billion won (10%) per case. Meanwhile, Korea Highway Corporation announced that it saved 575 billion won through a total of 757 design VE from 1997 to 2002. In terms of return on investment (ROI), in 2003, it invested 480 million won. As a result, the company saved KRW 15.1 billion, resulting in a big ROI 31. This is the result of systematic measures such as comprehensive measures for efficiency of public construction projects, technology development compensation system, and budget performance payment system, which have been continuously pursued by the Ministry of Construction and Transportation. It will be motivated to do so.

In the current construction work, various administrative acts such as budgeting, ordering, and contract management shall be carried out in accordance with the rules for the preparation of the planned price by the "cost calculation" in accordance with the "Contract on State Contracting Party". Although there may be differences in the rate of cost calculation, private construction works are doing the same work by drawing up a construction statement in the framework of the above cost. In order to prepare such a construction statement, the amount is collected by technology, large construction type, small construction type, and item, and then the unit price (material cost, labor cost, expense) is applied and the direct cost statement (cost consolidation) is collected and aggregated. It is a method of presenting the total construction cost by preparing a cost calculation statement of the project by applying various overhead cost rates. Such a historical system may have the following problems in identifying the total cost of detailed space in various fields.

In the "Review of the economic feasibility of the design" for cost reduction and quality improvement through the VE technique, the cost statement and the statement of the original design are not classified by detailed space and by item, and the classification itself Cost analysis is impossible because it is impossible, and the cost analysis of the original design plan for "review of the economics of the design" and the cost comparison of the alternative (improvement) design plan are based on the existing details, but the cost details for each detailed space item Cost calculations must be manually recalculated. In addition, the construction VE based on the construction technology development compensation system, like the design VE, is required to perform a cost analysis based on the current construction cost statement and the cost statement, and thus, it is impossible to analyze the cost by detailed space and item. In order to perform the VE, as illustrated in the above design economics and the like, the cost details and cost calculations have to be recalculated for each detailed space item, and thus, the VE is very difficult and requires a lot of time.

1 is a view of the existing construction work construction cost statement creation process. The existing process calculates the cost of construction cost related to the total construction cost such as indirect construction cost by processing the cost rate to the aggregated direct cost for the direct cost and the aggregated direct cost. It is impossible to grasp the total construction cost by detailed space due to the breakdown of journal entry and precise cost calculation.

2 is an example of a construction cost statement created by the process of Figure 1, it is possible to grasp the total construction cost after the cost calculation after direct construction of the cost calculation, and the total construction cost grasp by the detailed space because of the detailed space, breakdown journal entry and cost calculation It shows the impossible. As an example of the direct cost calculation table as an existing cost statement as shown in FIG. 3, not only the cost analysis of the total cost of construction by item and detailed space is possible, but also the cost of the total cost of construction is not available. As in the conventional direct cost statement, each business type statement is expressed only direct costs, it is impossible to analyze the cost of the total construction cost.

On the other hand, as shown in FIG. 5, since the indirect costs are appropriately estimated and resent the direct cost amount of the statement when calculating the cost of each model of the cost model during the performance of the conventional VE, there is a high possibility that an error occurs in accurate total cost calculation for each type of work. In addition, as shown in FIG. 6, the amount of function evaluation when preparing a function evaluation when performing a conventional VE also brings the amount from the cost model of FIG. 5, thus making it difficult to accurately calculate the total cost of each item. It is not possible to do this by a separate manual manual, which is not accurate.

Furthermore, as shown in FIG. 7, when the life cycle cost analysis is performed in the conventional VE, the existing construction cost is not classified by sub-space-item, so it is difficult to reconstruct the construction cost by sub-space-item of the original design, and the indirect cost after the direct cost journaling is appropriate. By estimating the journal entry, it is difficult to determine the precise total cost of each item. In this case, the calculation of construction cost by subspace-item of the alternative (improvement plan) is similar to the original design, and the indirect cost after the direct cost journalization is properly estimated by the journal entry, which leads to the difficulty in calculating the precise total cost of each item. high portential. On the other hand, in the life cycle analysis of the construction cost of the VE performance items when preparing the conventional VE proposal as shown in FIG. Overhead costs are appropriately estimated by the journal entry, making it difficult to determine the precise total cost of each item. And, in the life cycle analysis of the construction cost of the VE performance items when preparing the construction cost calculation of the conventional VE performance process as shown in Figure 9, the existing construction costs are not classified by sub-space-item items by sub-space of the original design plan It is difficult to reconcile the construction costs by each, and the indirect costs after the direct expiration are properly estimated, which makes it difficult to determine the precise total cost of each item.

In order to perform VE smoothly, the original design analysis and alternative (improvement) design analysis can be analyzed on the basis of easy, fast and accurate construction-VE construction support system based on the unit price and detailed space information of the existing statement. We propose a cost analysis system for a ready-to-use construction VE, but it will help to weaken the development of the construction industry.

As can be seen in FIG. 10, the construction VE information processing system 1000 includes a data acquisition unit 1110; The cost history basic data generation engine 1200 and the VE assistance information generation engine 1300 are included. The construction VE information processing system 1000 further includes a DB 1400 unit for storing and managing various data, and optionally, an interface module 1100, an interface module 1100 for supporting a seamless interface with a user, and It may further include a management module 1500 for performing various management functions, including a plurality of construction appraisal cost history information processing project management. The management module 1500 may include a cost rate information manager 1510 for managing cost rate information and a user manager 1520 for managing a user. The cost rate information manager 1510 manages the changed cost rate information when the cost rate is changed.

 11, when the construction VE information processing system 1000 operates in a predetermined server, the construction VE information processing system may be executed by a user computer 2000 connected to the server through a wired or wireless network 3000. The user can transmit and receive data to the construction VE information processing system 1000 while communicating via an interface provided by the method 1000.

The interface module 1100 includes a data acquisition unit 1110 that obtains data from the user computer 2000. When the data acquisition unit 1110 selectively obtains data in a special form or a predetermined form, an additional information acquisition unit which receives a special separate item from an acquisition data form providing unit 1111 providing an acquisition data form It may further include 1112. Meanwhile, the interface module 1100 includes an output selection information acquisition unit 1120 for receiving a type of output that the user wants to receive or selection information about elements to be included in the output, and an output of a preset type for the user. The output providing unit 1130 may be further included.

10 to 11, the construction VE information processing system 1000 includes a DB unit 1400, and the DB 1400 includes an acquisition data storage unit 1410 and a generation data storage unit ( 1420). The acquisition data storage unit 1410 includes a unit price information data unit 1411 about input unit price information, a quantity calculation information data unit 1412 related to quantity information, a cost rate information data unit 1413 related to cost rate information, and the like. There is this. The DB 1400 may further include a work data unit 1414 storing information on work classification and a space data unit 1415 storing information on space classification. The work classification is a classification system of work types from the highest hierarchy to the lowest hierarchy, such as large work-heavy work-small work-item (item name) and the like. Belong to The space classification refers to a structure system for the space constituting the facility from the lowest part unit to the highest facility unit. For example, with respect to the facility of a library, the first floor, the second floor, and the third floor are spaces in units of floors. The wall or the like may be a detailed space corresponding to the site. The generated data storage unit 1420 may include generated cost detail basic data or output information data generated by the output generator 1320, cost detail information data generated by the cost detail information generation engine 1300, or specialized information data. It is stored.

If an alternative design occurs, variations will occur in the type of work (including sub-names, items, breakdown items, items, and items of the subclasses in the work classification system), in which case, as well as changes in the type of work, According to this, the unit price information may change, and in some cases, the quantity per work-space may vary. Meanwhile, the cost rate may change based on a specific time point such as when designing a change. The change design may occur more than one order or n times, and variation information may be stored for each order, and several orders may be grouped according to a user's selection and processed in one large order unit. At this time, the DB unit 1400, if there is a change in the unit price information, work-by-sector-specific construction quantity, cost rate, etc., the change can be managed not only on the basis of the model, but also by the order of the alternative design.

Next, the construction VE information processing system 1000 of the present invention will be described in more detail.

12 to 15 are flowcharts of an information processing method of the construction VE information processing system 1000 of the present invention.

The construction VE information processing system 1000 generates cost breakdown basic data from firstly inputted part information, sector information, and space-specific quantity information, construction unit price information, and cost rate information. The cost breakdown basic data first generates indirect construction cost information for each type of work by referring to the unit price information and the cost rate information, and generates extended unit price information for each type of work using the generated indirect construction cost information and the direct construction cost information for each type of work. The cost breakdown basic data is generated by referring to the extended unit price information and the quantity calculation information using unit price information. The construction VE information processing system 1000 obtains quantity information for each part-type-specificity-space, unit price information for each type, and cost rate information. As shown in FIG. 12, the cost detail basic data generation engine 1200 of the construction VE information processing system 1000 may refer to the indirect construction cost information for each indirect construction cost constituent item by referring to the unit price information and the cost rate information for each model. Generate (S11), and construct extended unit price information for each type of construction by using indirect construction cost information for each construction type indirect construction cost information per item and direct construction cost information for each construction item directly (S12), and use the expansion unit price information and the quantity calculation information for each construction type. In step S13, preset cost detail basic data is generated.

The construction VE information processing system 1000 generates the cost breakdown basic data from the first-type quantity-specific quantity information, construction unit price information, and cost rate information. The cost breakdown basic data first generates indirect construction cost information for each type of work by referring to the unit price information and the cost rate information, and generates extended unit price information for each type of work using the generated indirect construction cost information and the direct construction cost information for each type of work. The cost breakdown basic data is generated using unit price information.

First, data input will be described. The construction VE information processing system 1000 obtains quantity information for each type-space, unit price information for each type, and cost rate information. On the other hand, the information obtained by the construction VE information processing system 1000 may further include information on the space classification, the information on the space classification may be included in the quantity information for each type-space It may also be input as separate data. In order to generate construction cost breakdown information for each space classification system, information about the space classification should be input. As input data of the present invention, there is an example of the location information (space configuration information) for each facility-specific space as shown in Table 1 below, and the quantity-specific calculation information for each model-space in FIG. 16. (In FIG. 16, information indicating that the first floor of 101 is formed by the sum of 101 to 105 is not shown. However, such space configuration information may appear in the quantity calculation information for each work type and space.)

101 buildings First floor No. 101 No. 102 No. 103 104 No. 105 101 buildings Second floor 201 No. 202 No. 203 No. 204 No. 205 101 buildings 3rd Floor 301 302 houses No. 303 304 305

 As illustrated in the above table, it can be seen that one building is composed of one to three layers, and the first floor is composed of Nos. 101 to 105. The location information data for each detailed space such as Nos. 101 to 105 may further include affiliation / classification information for each building or each building to form the spatial data unit 1415. If the quantity calculation information for each detailed space corresponds to FIG. 16, if the quantity calculation information additionally includes a layer-by-layer aggregation corresponding to an upper portion of the detailed space, or for each other space corresponding to an upper portion of the "dong" If there is a partial aggregation, location information (space configuration information) for each facility-specific space corresponding to Table 1 may be generated as the aggregation information. When the data of Table 1 and FIG. 16 or the data of FIG. 16 further includes aggregate information for generating spatial configuration information, corresponding information about “work type: space of an arbitrary unit” is generated. . Through the detailed location information data for each detailed space, each detailed space is further inputted with belonging / classification information for each floor and each building to form a spatial data unit 1415. The spatial data unit 1415 can configure a detailed spatial DB.

17 is a diagram of an example of unit price information data as input data. It can be seen that the unit price information includes direct costs for each item of construction costs, such as material costs, labor costs, and expenses, by type of work (item name).

18 shows that cost rate information is input as input data. For example, the indirect construction cost information generation engine 1210 of the cost detail basic data generation engine 1200 of the construction VE information processing system 1000 may refer to the construction cost information and the cost rate information for each indirect construction cost configuration item. Generate indirect construction cost information. The indirect construction cost information generation engine 1210 first generates indirect construction cost information for each indirect construction cost constituent item by reference to the unit price information and the cost rate information for each model (S11). Subsequently, the cost breakdown basic data generation engine 1200 configures the expanded unit cost information for each construction cost construction item by construction cost by using the generated indirect construction cost information for each construction type and indirect construction cost information for each construction item and direct construction cost information for each construction item. The cost breakdown basic data is generated using the extended unit price information (S13).

18 exemplarily shows that data regarding unit price information of each type is input. For example, the indirect labor costs among the indirect construction costs are labor costs * 10.0% of the direct construction cost information, industrial accidents-employment insurance costs (labour labor costs of the direct construction costs + the indirect labor costs) * 4.27%, and safety management costs are the labor costs of the material costs + direct construction costs. + Other expenses of other expense items) * Calculated for each indirect construction cost item by referring to cost information set in advance such as 1.81%. Of course, since the industrial accident-employment insurance cost requires the indirect labor cost information, it is preferable that the indirect labor cost is calculated in preference to the industrial accident-employment insurance cost. That is, when indirect construction cost information of at least one or more other indirect construction cost construction items is required for the calculation of a specific indirect construction cost construction item, it is preferable to first calculate the necessary indirect construction cost information. In this case, when all the indirect construction cost information for each indirect construction cost configuration item preset by the construction type is generated, the construction cost integrated item by combining the direct construction cost by the direct construction cost construction item and indirect construction cost by the indirect construction cost construction item by the construction type The information on the extended unit price is generated. An example of the generation of the unit-specific extended unit price information is shown in the example of the output of the present invention of FIG. 20. That is, in the output, it can be seen that construction cost by construction cost, construction cost, indirect construction cost by item, total, VAT, other and total cost information by construction type are generated. Can be indirect cost information.

Next, generation of the cost breakdown basic data for each model will be described in more detail.

The cost detail basic data is in charge of the aggregate data generation unit 1220 of the cost detail basic data generation engine 1200 of the present invention. The aggregate data generation unit 1220 generates cost breakdown basic data with reference to the extended construction cost information for each work type and the quantity information for each work type and space. The aggregate data generation unit 1220 generates two types of cost breakdown basic data. One is a method of generating preset multidimensional aggregate data, and the other is a method of generating only a few preset aggregate data. First, a method of generating multidimensional aggregate data will be described. The multidimensional aggregate data is generated by the multidimensional aggregate data generator 1221 of the aggregate data generator 1220 of the cost detail basic data generation engine 1200 of the present invention.

The cost breakdown basic data has three or more dimensions (axis). The first dimension is the construction cost dimension, the second dimension is the engineering dimension, and the third dimension is the spatial dimension. If the order is assigned to each change design, and the cost breakdown basic data is generated for each change design, the order may also be the dimension if there is a set of cost breakdown basic data corresponding to the far-field design.

The value constituting the cost breakdown basic data may be expressed as f (x, y, z). In this case, x may be an engineering dimension, y may be a spatial dimension, z may be a construction cost configuration item dimension, f is a cell value determined when (x, y, z) is determined. The cost history basic data generation engine 1200 obtains the first-obtained order-specific-type-space-specific quantity information, the type-specific unit price information, and the cost rate information, and generates f (x, y, z). Generating cube data such as f (x, y, z) may be computationally various.

As an example, a method of generating f (x, y, z) will be described. The cost breakdown basic data generation engine 1200 calls the indirect construction cost information generation engine 1210 to generate extended construction cost information for each combination of given xi and yj, and preferentially to all combinations of the given xi and yj. Z = z (xi, yj) is generated for every combination of xi and all yj as the extended construction cost information and the quantity calculation information. In the present invention, when generating the extended construction cost information, the expanded construction cost unit price information (direct construction unit cost + indirect construction cost unit price by indirect construction cost configuration item) including the indirect construction cost information for each indirect construction cost construction item first, and then as the quantity calculation information Although it is described as a first method of generating extended construction cost information, the generation of the extended construction cost information may be directly generated by directly reflecting the quantity calculation information on the unit cost of construction cost, and then by direct construction cost information (direct construction cost unit price * construction quantity) reflecting the quantity calculation information. A second method of generating extended construction cost information (extended construction cost unit price * construction quantity) with reference to the cost rate information may also be adopted. In the above, xi refers to the lowest space i of the space classification (for example, 101 space, which is a detailed space on the first floor, may be xi to 101 to 105), and yj denotes the lowest work classification (eg, FIG. 17). The model listed in the unit price information of may be jy). On the other hand, zk becomes a construction cost construction item.

Subsequently, the multi-dimensional aggregate data generation unit 1221 or the structured aggregate data generation unit 1222 of the cost detail basic data generation engine 1200 or the cost detail basic data generation engine 1200 calculates partial sums. Subtotals can be generated for each dimension for x, y, and z. The z-dimensional subtotals may include direct construction cost subtotals, indirect construction cost subtotals (the subtotals by indirect construction cost constituent groups may be generated), and total subtotals, which may be generated when the extended construction cost information is generated. The spatial dimension will be described first by way of example. For each yj combination (assuming subtotals for z have been generated), generate subtotals for xi. That is, the construction cost related to 101-105 for the specific construction type is subtracted by the construction cost of 101st 1st floor, and it totals into 101 construction cost with the total construction cost of 1st-3rd floor. Next, generate a subtotal sum of yj for all xi. If the work classification is composed of n hierarchies as in the above space classification, subtotal information for each hierarchical layer and sub-total hierarchies are generated. If there is only one layer, subtotal information can be generated for the entire work type. The generation of subtotals may be generated for any one dimension selected from (xi, yj, zk) or a combination of any two or more dimensions. Of course, it may not be generated for a particular combination. For example, for a particular zk, it may not be necessary to generate subtotals for every combination of (xi, yj) (indirect labor costs need to be created for a specific space, for a specific industry, or for a particular order). Indirect labor costs are usually justified with the overall overhead configuration item, so this kind of data generation may be unnecessary unless it is a special case.)

An example of the generated cost detail basic data may be FIG. 19. The cost breakdown basic data has three or more axes. The first axis (dimension) is the construction cost axis, the second axis is the engineering axis, the third axis is the spatial axis, and sometimes the order axis or the VE project axis. The cost detail basic data such as those shown in FIG. 20 are generated as the construction cost configuration item axis and the work axis. (FIG. 20 shows cost detail data for each construction type-construction cost for 101-101 (example of the lowest space). In this case, the work classification system may be reflected, and the work classification system is 2 It may be a hierarchical classification scheme. The work type may be classified into a work size such as a large work type, a hollow work type, and a small work type, and the bottom of the work class classification may include a minimum unit of the work type, and the minimum unit may be “item”, “item”, or the like. It is sometimes called the equivalent name. As can be seen in FIG. 20, when a specific work includes one or more sub-work types, subtotal information may be generated for each work type. The painting work of Figure 20 is common 08 (water-based paint roller-interior wall twice class 2), common 08 (water-based paint roller-chill interior 2 times class 2), common 10 (ceramic paint-2 times) Construction cost by construction cost information for each construction item by sub-model such as public 08, public 09, public 10, etc. and construction cost by construction cost by sub-type construction cost such as public 08, public 09, public 10 etc. It can be seen that additional subtotal information can be additionally generated. In the example of FIG. 20, the type of work is divided into one step or two steps, but even when n (n> 2), aggregate information may be generated in each step. Of course, the total cost information, total cost information, total cost information, total cost information, etc. may be further generated in the cost detail basic data, such as total sum or total cost of FIG. 20. Of course, the total information may be generated at the time of generating the extended construction cost information. Information such as VAT or other expenses may be generated from the extended construction cost information, but may also be generated when the cost detail basic data is generated.

On the other hand, the output of Figure 22 shows an example of the cost breakdown information by type-space. The axis used in FIG. 22 is a coaxial axis and a space axis. Spaces 101 to 105, which are the spaces shown in FIG. 22, are an example of the lowest detail space. Of course, there may be more sub-spaces (elements such as small space-wall, ceiling, etc.) than the 101 to 105, in this case, the construction quantity information is the construction quantity information by sector-part Of course, it should be included, in this case it will be possible to generate the cost history basic data as shown in FIG. On the other hand, in the example of Fig. 22, the display of the upper space (e.g., Nos. 101 to 105 belong to the first floor, and the first floor to the nth floor are combined or the 101 to n05 (n is an integer) are summed to 101 Hierarchical classification of space, such as forming a building, building 101 and other buildings together to form a complex) is not shown, but it will be apparent to one skilled in the art that the upper space of the lowest space appears, and their aggregate information (e.g., The upper spaces 101 to 105 may be aggregated information on the first floor, or 101 spaces may be generated by aggregated information from 101 to n05. In the present invention, the input of data indicating the spatial hierarchy is not separately mentioned, but it will be obvious that they are included. The input of the spatial hierarchical structure is 1) a method of directly inputting a spatial hierarchical structure (101 is a method of inputting a structural structure of a space such that n layers are composed of n01 to n05); , When entering the construction quantity information, the quantity calculation information by the method of inputting the aggregate information including the spatial hierarchy (for example, by the lower space and the upper space (consists of the quantity aggregation information of the lower space) together A method of inputting quantity calculation information, a method of inputting quantity calculation information for each lower space, and then inputting aggregate information for each upper space, or inputting spatial hierarchy information) may be used.

In the above, examples of the construction cost-construction items in the cost detail basic data, the production method of the cost detail basic data in terms of the work-space, and the results of the generation are presented. On the other hand, in the same manner as the cost detail basic data, the value of each cell of the matrix constituted by two or more axes selected from among elements constituting a plurality of axes such as work type, space, construction cost construction item, and order can be calculated. Meanwhile, a subtotal for each axis (for example, in the case of a construction cost constituent item, the direct construction cost sum, the indirect construction cost sum, etc. may be a partial sum) may be further generated in the cost detail basic data.

Although not shown in the drawing, the data based on the space-construction cost configuration item may be generated in the cost detail basic data similarly to the method of generating data according to the work-construction cost configuration item or data according to the work-space. For example, the construction cost configuration items as shown in FIG. 20 on the X-axis, and 101 to 105 (subtotal sum may be included in the X-axis of FIG. 22 instead of the work of FIG. 20 on the Y-axis. .) And cost-based data values can be generated in each cell of the X and Y axes.

The cost history basic data generation engine 1200 generates the cost detail basic data according to an embodiment of the present invention. For each specific detailed space (e.g., 101-101), indirect construction cost-by-item items are referred to the direct construction cost information and the cost rate information for the corresponding construction-construction quantity information and construction-construction cost information (direct construction cost information). The calculation of the indirect construction cost information is performed first, and the expansion construction cost information is generated. The construction cost information for each specific construction space is generated by using the expansion construction cost information for the specific detailed space. Subsequently, the same calculation is performed for the next specific subspace (101 101). When this is performed for every detailed space, the cost breakdown basic data for each work-specific construction cost is generated for every detailed space. Subsequently, the cost detail basic data generation engine 1200 may generate subtotal (intermediate aggregation) data for each axis (contract-space-construction cost configuration item), and then generate intermediate aggregate data for two or more axes. have.

On the other hand, in the construction VE, it is important to grasp the change in construction cost in terms of design change or alternative design over time. When there is a design change or alternative design (hereinafter referred to as alternative design), the individual alternative design shall be managed in the order of individual alternative designs in units of individual alternative design units or groups of two or more of said individual alternative design units. Can be. For example, in the case of the first case, the work i1 and work i2 can be introduced as an alternative design, the work order i and work i2 can be changed and managed separately, and the work i1 and work i2 can be grouped into one order. Can manage For the sake of convenience, the order management will be described for each work type i, but the order management is not limited thereto. Existing work j (It will be obvious that work j may be a plurality of work.

Here, as an alternative design of the work type replaced by the work type i (it may be possible to have several types of work), as the work type j instead, the unit price information per work type (direct cost information) There will be a change, and the quantity information by type may also change. When the construction cost information changes directly according to the introduction of the work type i, the indirect construction cost information for each indirect construction cost configuration item also changes. Accordingly, the cost detail basic data generation engine 1200 is described above based on the unit price information, the quantity information for each type, and / or the cost rate information (only if there is a change) according to the type I, which is an alternative design obtained. Create the same cost breakdown basic data. Of course, in this case, quantity information for each type of work type j is deleted or not processed to be omitted from the generation of cost detail basic data. In this case, the cost detail basic data may be generated only in a part related to the work type i in which the alternative design has occurred, but the entire cost detail basic data may be regenerated. Partial or totally regenerated cost breakdown basic data can be managed for each order. At this time, the order is managed in association with the work type i that caused the order.

On the other hand, the order is an arbitrary element that can fluctuate initially generated cost breakdown basic data. Variation of type is an example of variation. For example, a new order is also generated when various cost factors occur, such as cost rate fluctuations, additional cost factors (e.g., delayed construction costs due to construction delays), and the like. It would be desirable to generate cost breakdown based data.

Considering the order as one dimension / axis, the value constituting the cost breakdown basic data may be expressed as f (x, y, z, w). In this case, x may be a coaxial axis, y is a space axis, z is a construction cost configuration item axis, w may be a degree axis. The cost history basic data generation engine 1200 obtains first-type quantity information for each type-space, unit price information for each type, and cost rate information as first input information, and generates f (x, y, z, 1). For example, when a variation occurs in the quantity-specific information, the price-specific information, or the cost-rate information for each type due to an alternative design, f (x, y, z, 2) may be generated using the change as the second input information. .

The construction VE information processing system 1000 may store f (x, y, z, w), which is a cost detail basic data pack, in a conventional method performed in a computer processing. In the conventional method, the value of (y, z) may be stored as a separate file for each type of x and for each subtotal of x, and as a separate file for each type of y (the work level or the lower item level of the work) , z) value, and store the values for all the sub-items that make up z for z, or sub-total the sum of the sub-items (for example, direct construction cost sub-material cost + labor cost + expense, Indirect construction cost subtotal, etc.), or the above detailed item-specific values, subtotals and totals may be stored. Such a (x, y, z) structure is shown by way of example in FIG. Those skilled in the art will be able to introduce various computational processing methods to implement the teachings of the present invention.

In this case, the number of each cell is a minimum value of a product of x number, y number, and z number, and there may be a cell associated with the subtotal. On the other hand, it is natural that a plurality of null data exist among the cells. (Because there may not be a specific work in a specific detail space.) The order and method of calculating the f may be extremely diverse, and those skilled in the art can select the optimal method among these various methods (a small amount of calculation or a fast calculation speed). Method, etc.), and the method may be within the scope of the present invention.

On the other hand, in order to avoid a large number of null data, assuming that the output of the present invention shown in Figure 20 to 23 illustratively, there is a method for calculating only the data required for each output form in a batch (batch) method. For example, there is a method of generating the output of FIG. 20 in batches for all lakes of every motion. Of course, in this case, it will be obvious that the indirect construction cost information for each indirect construction cost construction item is preferentially calculated using the direct construction cost information. With reference to only the defect information, work type information, and unit price information (indirect construction cost information previously generated) corresponding to 101, the cost calculation statement may be generated in the form of an output of FIG. 20 corresponding to 101. A cost calculation statement for 102 may be generated with information corresponding to 102 (assuming 102 after 101). As described above, when the cost calculation history information is calculated for each space of the lowest unit such as 101, 102, etc., it is possible to generate aggregate information for each upper space of the detailed space (for example, 101 building to which 101 belongs). will be. The generation of the aggregate information may be generated by summing the cost calculation values of the detailed space corresponding to the upper space by the defect type, the type of work, and the construction cost construction items. In this manner, for the outputs of various types, the cost calculation value may be generated for each space, higher space, or for a predetermined group, and the generation may be processed in a batch manner.

In the case of three-dimensional data processing, an example of a method for calculating f is as follows. First, grasp the type and quantity of each product by unit name, calculate the construction cost directly for each type of work, and then refer to the cost rate information based on the direct construction cost, indirect labor costs, machine expenses, industrial accidents, employment insurance premiums, and health pension premiums. Indirect construction costs such as retirement deductions, safety management costs, other expenses, environmental conservation costs, general management costs, profits, and VAT can be calculated.

The construction VE information processing system 1000 generates at least one or more preset analysis information using cost detail basic data for at least one selected from the space, the work type, and the construction cost configuration item. The analysis information may be a partial sum or a total sum of any one or more selected from the space, the defect type, the work type, and the construction cost. Examples of generating the analysis information are shown in FIGS. 20 to 23.

According to the present invention, indirect construction cost information may be preferentially generated by directly processing cost information by receiving and utilizing cost rate information from an initial stage of generating analysis information. Indirect construction cost information is generated preferentially, and total construction cost information in all processing units can be easily generated using direct construction cost information and indirect construction cost information. All the processing units are any combination of two or more selected from space (by the higher unit space of the detailed space will be obvious), by the type of the object (the group will also be included by the group), and by the construction cost construction item. Given more than one, it would be easy to generate total cost information for the given combination. FIG. 20 shows that the construction cost and the total construction cost for each construction cost construction item are processed in the total cost column for each specific space for the specific detailed space (101 101).

In order to generate a result as shown in FIG. 20, the value of each cell corresponding to the indirect construction cost information of FIG. 20 may be generated using the direct construction cost information and the cost rate information only by the direct construction cost information by the type of work for each order, and the value of the cell is generated. Subtotals / subtotals and total cost or total values can also be generated. On the other hand, in the present invention, since the cost cost information for each space, the type of work, and the construction cost configuration items are generated for each order using the cost rate information, partial sums and total sums can be easily generated. The subtotals and totals may be generated together with the cost information generation, or may be generated while the outputs are generated when a user requests a specific output.

Meanwhile, if the cube data as shown in FIG. 19 is generated, the output may be generated by slicing or diceing the output. Meanwhile, a roll up operation may be included in generation of the aggregate information. Roll-up operation means that when 101 (101) is composed of 101 to 105 (direct sub-components), the values constituting 101 are added to 101-105 values (direct sub-sub). It is an operation that adds the values of the components to make a value for 101 building (the value of the parent component). The generation of the subtotal information is preferably generated by the cost detail basic data generation engine 1200 of the present invention.

20 is an exemplary diagram illustrating that the construction VE information processing system 1000 directly generates indirect construction cost information using construction cost information and other information. As can be seen in FIG. 20, various indirect construction cost detail items are generated through a predetermined formula with reference to direct construction cost items such as labor costs. Information such as the example of FIG. 20 is in charge of the cost history based data generation engine 1200 of the present invention. As can be seen in Figure 20, you can create a cost-consolidation statement by sector-space for each building, you can create a cost consolidation statement table for each building, you can create an integrated cost-consolidation statement (direct costs) for each building, each space You can create total aggregate, aggregate aggregate by each building, and aggregate aggregate by space.

The integrated cost calculation means that the total cost of the construction includes the indirect construction cost, wherein each sub-item constituting the indirect construction cost is linked to the direct construction cost, the direct construction cost construction detail item, or the indirect construction cost construction item. In order to connect the construction costs, the cost rate information is required simultaneously with the direct construction cost input step (the unit price information input step) and sequentially, sequentially, and indirectly, and the indirect construction cost is connected and calculated with reference to the cost rate information. Since all indirect costs are always included, these cost-linking relationships are always maintained by industry (including by item) and by space.

24 through 26 illustrate input information for alternative designs. FIG. 24 is an exemplary diagram of quantity-specific data by type and space as input information for an alternative design. FIG. 25 is an exemplary diagram of unit price data by type of work as input information for an alternative design. For example, the original design included common 08 (aqueous paint, roller paint) and common 18 DRY WALL (C-65), but alternative designs are being replaced by common 18 SPC partitions. If the SPC partition is an alternative design, the DRY WALL will be eliminated, and depending on the nature of the SPC partition (no paint is needed), the common 08 (aqueous paint, roller fill) will also be unnecessary. Thus, in an alternative design, public 08 (aqueous paint, roller fill) may be missing the item itself (missing from the quantity data or unit price data items in FIGS. 24 and 25), but the item may be treated as zero. will be. Yellowed portions in FIGS. 24 to 25 are data for SPC partitions introduced in an alternative design.

 FIG. 26 is an exemplary diagram for input of cost rate data as input information for an alternative design. If there is a change among the items constituting the cost rate data, the change is entered. If there is no change, the same content as in the original design is entered.

Subsequently, when the input information for the alternative design as illustrated in FIGS. 24 to 26 is input, the cost detail basic data generation engine 1200 generates the cost detail basic data for the alternative design. An example of the cost breakdown basic data is in FIG. 35. In FIG. 35, unlike in FIG. 19, it is shown that the information displayed on the order axis, such as an alternative design (order 2nd order), is the cost breakdown basic data for the alternative design. The cost breakdown basic data for the alternative design is equivalent to the cost breakdown basic data for the original design.

27-30 illustrate one embodiment of a cost statement for alternative designs. FIG. 27 is an exemplary diagram of a cost calculation statement of the present invention for a construction cost breakdown by a construction-cost ratio construction item for a specific detailed space created for an alternative design. FIG. 28 is an exemplary view of a cost calculation statement of the present invention for a construction cost breakdown by a construction-cost ratio construction item for a specific upper space generated for an alternative design. FIG. 29 is an exemplary view of a cost calculation statement of the present invention for the total work for each item of detail space generated for the alternative design. FIG. 30 is an exemplary diagram of a cost calculation statement of the present invention for the total work for each item of the upper space generated for the alternative design.

Next, a method of generating VE support information of the construction VE information processing system will be described.

The first method is related to FIG. Based on the first cost details that are obtained before the alternative design occurrence (first input information), quantity information for each type-space, unit price information for each type, and cost rate information are obtained as first input information (S21), and set as first input information. The data f (x, y, z, 1) is generated (S22), and various analysis information (output (for example, FIGS. 20, 21, 22, 23, etc.) based on the generated cost detail basic data. ) Is one example. Subsequently, change information on at least one or more of the input information (second input information) reflecting the alternative design, the work type-space-specific quantity information, the work type unit price information, and the cost rate information is obtained as second input information (S24). In operation S25, the second cost detail basic data (f (x, y, z, 2)), which is second cost detail information preset as the second input information, is generated. Subsequently, the analysis information preset as the VE assistance information is generated with reference to the cost history information generated as the first input information and the cost history information generated as the second input information (S26), and the analysis information is generated as an output ( S27). The analysis information may be comparative analysis information of a predetermined type. The first cost breakdown information has the same meaning as the first cost breakdown basic data, and the second cost breakdown information has the same meaning as the second cost breakdown basic data.

The output refers to output data. The output may be in a form that can be recognized by a person, but may be in a form of data that can be recognized by a predetermined third system. The third system includes a 3D CAD system, an EVMS system, a construction appraisal information processing system, a planned price preparation system, a cost analysis system, a construction project management system, a construction cost settlement system, a construction supervision system, a BIM support system, a construction client side system, The construction VE information processing system 1000 of the present invention may be connected to or connected to a part of the third system or the third system through a wired / wireless network 3000. May be used.

The construction VE information processing system first obtains quantity information for each type-space, unit price information for each type, and cost rate information as first input information, and generates first cost detail information preset as the first input information. Cost analysis information generated as input information is used to generate preset analysis information as VE support information, and change information on at least one of at least one of work type, work type-space quantity information, work unit price information, and cost rate information. Obtains second input information, generates second cost detail information preset as the second input information, and includes at least one of cost detail information generated as first input information and cost detail information generated as the second input information. Reference analysis to generate the preset analysis information as the VE support information.

The second method receives the first input information and the second input information at the same time without a large or time difference, and for each of the cost history basic data f (x, y, z, 1) and f (x, y, z , 2), and generate preset comparative analysis information in a preset format and then output it. A description with reference to FIG. 14 is as follows. First, obtain the quantity information by each type-space, unit price information by each type and cost rate information as the first input information (S31), and changes to at least one or more of the quantity information by each type-space, unit price information by each type and cost rate information Obtaining the information as the second input information (S32), generating first cost detail information preset as the first input information (S33), and generating second cost detail information preset as the second input information (S34). By referring to any one or more of the cost history information generated as the first input information and the cost history information generated as the second input information, the analysis information preset as the VE support information is generated (S35), and the analysis information is output. To generate (S36).

The third method generates cost breakdown basic data f (x, y, z, 1) as the first input information, and generates cost breakdown basic data f (x, y, z, 2) as the second input information. This method generates and outputs the set comparative analysis information in a preset format. A description with reference to FIG. 15 is as follows. First, the quantity information for each type-space, the unit price information for each type, and the cost rate information are obtained as the first input information (S41), and the first cost detail information preset as the first input information is generated (S42), and the space for each type-space The variation information on at least one of each quantity information, unit price information, and cost rate information is obtained as second input information (S43) to generate second cost detail information preset as the second input information (S44). And generating analysis information preset as VE assistance information by referring to at least one of the cost history information generated as the first input information and the cost history information generated as the second input information (S45), and outputting the analysis information. To generate (S46).

The first method provides a variety of analysis information (eg, FIGS. 20, 21, 22, 23, etc.) for f (x, y, z, 1), which is the basic cost data, to provide alternative design points. It can be used even better when extracted. When performing a multi-faceted analysis of f (x, y, z, 1) centered on a work, it is easy to extract a work that can be accessed from a cost standpoint, and focus on them when planning alternative designs. You could do it.

The VE assistance information generated by the VE assistance information generation engine 1300 includes generation of preset comparison information for the original design and the alternative design. 31 to 34 illustrate an embodiment of output in a predetermined format related to the comparison information generated by the VE assistance information generation engine 1300. FIG. 31 is a VE supporting information of the present invention, which provides information on the total construction cost and the total difference between the original design by the upper space and the alternative design, and the difference between the original design and the alternative design. Example drawing. 32 is a VE support information of the present invention provides information on the total construction cost and the total cost of the alternative design and the difference according to the original design for each detailed space for the analysis result that can compare the construction cost between the original design and the alternative design Example drawing. As can be seen in FIG. 31, when the alternative design is adopted, it can be seen that construction cost of 658,689 won for building A and 1,317,378 won for building B is reduced. The analysis information as shown in FIG. 31 includes the total median sum totals (sums of Nos. 101 to 105) collected and analyzed for the original design, and the SPC partitions (class 18) that replace the type 08 and type 18 in the alternative design. It can be compared with the total median data included, aggregated and analyzed. The analysis values (29,868,818) for the original design are at f (x, y, z, w), where x is the sum of the value of x1 for species 8 and the value of x2 for species 18, and the y coordinate is A (A total of 101-105), z coordinate becomes a sum total of a construction cost constitution item, and w coordinate becomes primary. The value for the circle design of FIG. 32 is the above f (x, y, z, w), where x is the sum of x coordinates for type 8 and x2 values for type 18, and y coordinate is A-101, A-102, A-103, A-104, and A105, respectively, z coordinates are the sum of all construction cost construction items, and w coordinates are primary. Because the two designs of the original design are changed by the alternative design SPC divider, the analytical value should be the sum of the construction costs for the two models of the original design.

The analysis values (29,210,129) for the alternative design are in f (x, y, z, w), the x coordinate is the work type 18, the y coordinate is the A building (total of 101 to 105), and the z coordinate is the construction cost construction item. The sum total and the w coordinate are quadratic. The value of the alternative design of FIG. 32 is f (x, y, z, w), where x is the type 18, y is A 101, A 102, A 103, A 104. And A-105, respectively, z-coordinate is the sum of all construction cost construction items, and w-coordinate is secondary. (In this specification, A is used in the same sense as 101, B is 102).

Likewise, when there are n alternative design elements (n is an integer), there are mij original design elements that are deleted or changed by the ni for each ni. At this time, when the VE assistance information generation engine 1300 generates the analysis information, the construction cost of the original design plan for the mij that is changed by ni and the construction cost of the alternative design element related to the ni for each alternative design element ni is determined. (An example of ni may be an SPC partition, an example of mij may be an aqueous paint roller and a DRY WALL.) Meanwhile, the VE assist information generation engine 1300 may cost construction costs for all nis. You can also compare the sum of the breakdown information and the sum of the cost cost breakdowns of all mij's for all nis. In the present invention, for convenience of description, the description of one work for the alternative design, two work of the original design affected by the alternative design, but this is only for the convenience of explanation, and of course, the work related to the alternative design may also be n. However, it will be obvious that the present invention is applicable in such a situation.

33 is a VE support information of the present invention generated by the VE support information generation engine 1300, and the construction cost for the construction cost and the alternative design plan according to the original design plan for each construction type and approximate construction cost configuration item that differs between the original design plan and the alternative design plan. And an analysis drawing that provides information on the difference and compares the construction cost between the original design and the alternative design. 34 is a VE support information of the present invention provides information on the construction cost and the difference for the construction cost and the alternative design plan according to the original design proposal by the construction type and detailed construction cost configuration items that differ between the original design plan and the alternative design plan One exemplary diagram of analytical results for comparison of cost of alternative designs. As can be seen from FIGS. 33 to 34, the savings for each construction cost item for the original design and the alternative design are accurately calculated and can be compared and output. On the other hand, the comparison output will be possible for each part. Cost-based basic data for each part including the information for each part is generated through the construction VE information processing system of the present invention, and the cost details related to the type of work according to the original design plan and the work plan according to the alternative design plan Relevant cost breakdowns can be compared by segment. In order to do this, each part should correspond to each type by 1: n in relation to quantity. That is, when there are n parts in one detail space, one or more types of work are corresponding to each of the n parts, and each work type must include construction quantity information for each part-detailed space. Through comparison of each part as described above, it can be seen how the alternative design can reduce how much construction cost in which part. On the other hand, the construction VE information processing system of the present invention, when a plurality of models corresponding to the alternative design, extracts which site corresponding to the type of work by combining a plurality of models or a plurality of models, and in which site according to the alternative design You can produce output that tells you how much you can save. This will show where the alternative design is related and how much construction costs can be saved (and in some cases raised) in that area.

The construction VE information processing system of the present invention includes an interface module 1100. The interface module 1100 has an acquisition unit that receives various data such as quantity information for each type of work-space, cost information for each type of work, and cost rate information. Meanwhile, there is an output selection information acquisition unit 1120 for selecting the output desired by the user, and the system processes the output selection information obtained by the output selection information acquisition unit 1120 to generate an output. The generated output is provided to the user computer 2000 through the output providing unit 1130 of the present invention.

In the case of selecting the output as shown in FIG. 34, the output selection information acquisition unit 1120 receives selection information regarding the form of the output from the user. The selection information may include information to be included in the horizontal axis (in this case, construction cost information and total information for each component of construction cost), and work information having a difference between the original design plan and the alternative (improved) design plan. When there is such a selection, the VE assistance information processing unit 1310 of the VE assistance information generation engine 1300 performs construction cost information for each construction cost item for the selected model of each original design and construction cost for the selected model of the alternative design. Cost information is obtained from the cost breakdown basic data associated with the original design proposal and the cost breakdown basic data associated with the alternative design scheme, and the respective cost cost information is presented by the construction cost construction items, and both are calculated by the construction cost by the construction cost. Provide as supporting analysis information. In this case, when there are n alternative design items, the n items may be presented at once, processed individually, or may be processed by grouping several groups. Such grouping is at the user's option.
