Description

  The present invention absorbs inconsistencies in various elements that occur in construction when constructing collective-type real estate such as apartment buildings and commercial buildings such as condominiums, and in planning, design, construction, finishing, advertising, and sales work. The present invention relates to a collective real estate construction system that reduces rework and realizes efficient construction and subsequent management.

  In Japan, collective real estate such as condominiums such as condominiums and commercial buildings in which a plurality of offices are occupying is constructed in many places. The feature of the construction of these collective real estate in Japan is that it is a pyramid type business where planning, design, procurement, construction, interior decoration, advertisement, sales, etc. are performed by subcontractors and subcontractors, with a major construction company at the top. is there. In other words, although there is a vertical and horizontal division of labor system, there is a problem that there is little exchange of information due to the carefulness of standardization unique to craftsmanship.

  It has pride as a craftsman unique to Japan, and exists in work where hidden technologies and skills are divided. However, the speed of information innovation has increased consumer demand, so it is important that drawings and design information in planning, basic design, detailed design, procurement, construction, interior, advertising, sales, etc. do not cause inconsistencies It is. Here, in the planning, the design concept of the apartment or commercial building is developed. Next, based on this design philosophy, a design office or the like creates design drawings of condominiums and commercial buildings at the design stage. Based on this design drawing, the construction company, exterior company, interior company, etc. will carry out detailed design and construction. Also, as a custom of selling condominiums and commercial buildings, we recommend admission advertisements and contracts before construction is completed. For this reason, a tenant advertisement and a model room are created based on the drawing created by the design office. That is, the drawing created by the design office is used for all subsequent detailed design, procurement, construction, interior decoration, advertisement, and sales.

  However, the basic design drawing created by the design office, which is the basic design, may have inconsistencies with the design concept at the planning stage. Or after a basic design, in order for a different contractor to perform detailed design, procurement, construction, interior, etc., each may recreate a detailed drawing according to the convenience of the company. Even if each contractor after the basic design follows the basic design drawing, as the actual construction or construction progresses, the situation where the building or construction does not proceed according to the basic design drawing also occurs. For example, in the basic design, the dimension of a certain room is determined to be a certain value. However, it may be necessary to construct a room smaller than this dimension for convenience of procurement and construction. This is because basic design often does not completely assume inconsistencies that may occur in subsequent construction and construction in order to prioritize design philosophy.

  In addition, because planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, sales, etc. are vertical and horizontal division of labor, the basic design has been completed. Create detailed specifications in parallel. In this case as well, inconsistencies may occur in the detailed design and detailed specifications created by each supplier depending on the actual construction and construction. If construction proceeds with this inconsistency, real estate different from the basic design may be constructed, or rework to absorb the inconsistency may occur.

  As described above, the construction of collective real estate in Japan is likely to have the above-mentioned problems because contractors having different roles are realized with a pyramid structure such as subcontracting and subcontracting. There is a situation where it is difficult to deal with preventing real estate that is different from the basic design and reworking by exchanging information with each other and absorbing mutual inconsistencies. . This is partly because consumer demand has gone beyond technological evolution.

  In addition, if a condominium or commercial building that has actually been completed is constructed with a construction different from the basic design drawing, it may cause complaints from the purchaser. For example, drawings and information of condominiums and commercial buildings used in advertisements and sales are created at the stage where a basic design drawing is created. For this reason, drawings and information used for advertising and sales are based on basic design drawings. On the other hand, as the actual construction and construction progress, the completed condominiums and commercial buildings will deviate from the basic design drawings, and the purchasers and residents will naturally have the drawings and information confirmed at the stage of advertisement and sales. This is because claims are made for differences.

  In such a situation, for example, techniques for absorbing defects in construction such as walls and floors have been proposed (see, for example, Patent Documents 1 and 2).

JP-A-7-233578 JP 2006-169810 A

  However, the technology including Patent Documents 1 and 2 is a technology only paying attention to a part of the real estate to be constructed. It does not focus on issues such as rework and inconsistencies based on vertical and horizontal division of labor in the construction of collective real estate.

  As described above, there are the following problems in the conventional technology and the construction of collective real estate in Japan.

  (Problem 1) Inconsistencies in drawings and specifications in planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, sales, etc. are not absorbed, so rework is likely to occur in the second half of construction.

  (Problem 2) Since the mismatch of drawings and specifications in planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, and sales is not absorbed, there is a gap between the drawings of advertisement and sales and the actual finish. And customer complaints are likely to occur.

  (Problem 3) Since planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, and sales have individual drawings and specifications, after the real estate is handed over to the management company, Such common information is lost.

  In view of the above problems, the present invention creates a database of definitive design information by absorbing inconsistencies in drawings and specifications that occur in various division of labor systems such as planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, and sales. An object of the present invention is to provide a new collective real estate construction system that does not cause the above problems 1 to 3.

  A collective real estate construction system according to the present invention includes a storage unit that stores a basic design drawing of a collective real estate, an extraction unit that extracts a design element included in the basic design drawing, and a mismatch between the design element and the construction element. And a matching means for detecting consistency.

  The collective real estate construction system of the present invention makes full use of craftsman's skills and skills peculiar to Japan, and at the early stage of construction, planning, basic design, detailed design, procurement, construction, interior decoration, advertisement, and sales Inconsistencies in drawings and specifications can be absorbed, reducing rework in the second half of construction.

  In addition, the drawings and specifications used for advertisements and sales do not cause a deviation from the basic design and detailed design, so that it is possible to reduce complaints from customers who purchase real estate.

  In addition, since the final design information in which inconsistencies are absorbed is recorded in the database, the necessary information is provided to buyers and managers even when real estate is sold second-hand or resold. The For this reason, long-term utilization and management of real estate become easy, and activation of the real estate market can be expected.

  (Embodiment 1)

Embodiment 1 will be described.
First, the flow of construction of a conventional collective property will be described. FIG. 1 is a flow chart of collective property construction in the prior art.

  In collective real estate construction in the prior art, basic design is performed in step ST1 to create a basic design drawing. In the basic design, a basic design drawing of the building that will be the real estate is created based on the planning and specifications of the collective real estate as the premise. In practice, the design office creates a basic design drawing based on the plan and specifications. The basic design drawing includes the layout and layout of each room of the collective real estate, the layout of each room, the layout of common parts, dimensions, and various necessary design expressions. This basic design provides a basic design drawing to the next stage.

  Following the basic design, construction design for creating a construction design drawing used for actual construction is performed in step ST2. For example, a general contractor or a contractor performs construction design. In this construction design, a basic design drawing is used, but actually, the construction design is performed based on construction elements based on know-how accumulated in the contractor, rather than sufficiently following the basic design drawing. This is because when actually performing the construction, a construction design drawing that depends on a unique expression format or description method according to the original technology of the general contractor or the contractor is required.

  A construction design drawing is created in step ST2 of this construction design.

  After the construction plan is created, actual construction is performed in step ST3. General contractors and contractors perform the actual construction. This construction is divided into a phase for designing the entire collective property, a phase for exterior, a phase for interior, etc., and different contractors perform the work. For this reason, it has a different construction element for every different contractor, and the expression form of the same member and composition is often different. For this reason, the construction design drawing is frequently rewritten or recreated as the construction stage proceeds. This is because it is difficult to absorb the difference between the basic design and the construction when the basic design drawing is changed to the construction design drawing.

  When the construction of step ST3 is completed, the collective real estate is completed in step ST4.

  In addition, when a basic design drawing is created in step ST1, this basic design drawing is used for advertising and sales as it is. That is, in step ST5, advertisement and sales are performed using the basic design drawing. That is, a basic design drawing is used in advertising / sales. Similarly, when the completion in step ST4 is completed, the completed collective property is transferred to management in step ST6. In real estate management, construction design drawings based on basic design drawings are used, and construction design drawings are used in structure management. Alternatively, in all management, a completed blueprint based on the basic blueprint is used.

  As is apparent from the flowchart of FIG. 1, the basic design drawing and the construction design drawing are often not considered to be consistent with each other. Therefore, (1) Drawings of real estate used in advertising / sales and management differ from drawings actually used for construction (representing the real estate for which this drawing is completed), (2) Basic design drawing And the construction plan that will be created there may not be corrected, the collective real estate constructed by the construction plan does not reflect the design philosophy included in the basic plan, (3) Since there is no inconsistency correction, the number of corrections during construction of the construction plan increases. (4) Reworking is likely to occur due to differences from the basic design that occur as construction progresses. (5) Basic It is easy to generate complaints about inconsistencies between blueprints (used for advertising and sales) and completed collective real estate. (6) After entering management, based on the basic blueprint that is saved with the actual collective real estate. Ku difficulty of management due to the drawings, which Buyer is presented is different, give rise to problems such as.

  As shown in the flow of FIG. 1, after the basic design drawing is created, these are caused by the creation and construction of the construction design drawing without correcting the inconsistency with the actual construction elements. .

(Overview)
The collective real estate construction system of the present invention solves the above problems (1) to (6). First, an overall outline will be described with reference to FIG. FIG. 2 is a block diagram of the collective real estate construction system according to Embodiment 1 of the present invention.

  The collective real estate system 1 includes a storage unit 2, an extraction unit 3, and a matching unit 4. The storage unit 2 stores a basic design drawing of a collective real estate. The extraction means 3 reads the basic design drawing from the storage unit 2 and extracts the design elements included in the basic design drawing. The matching means 4 detects a mismatch between the design element and the construction element and takes a match (that is, corrects the mismatch). The collective real estate construction system 1 can prevent the deviation from the subsequent construction design drawing and the construction by giving the basic design drawing consistency in consideration of the construction elements in advance. In particular, the alignment means 4 outputs a finalized drawing after alignment.

  In this finalized drawing, inconsistency between the design element and the construction element included in the basic design drawing is corrected, and the construction drawing created based on this finalized drawing does not have unnecessary inconsistency. Basic design drawings are often created at design offices and architecture offices, but include different creation elements from actual construction depending on the customs of design offices and architecture offices. For this reason, a basic design drawing will have inconsistency with an actual construction and a construction design drawing.

  On the other hand, by using the collective real estate construction system 1 according to the first embodiment, inconsistencies based on the customs of design offices and architecture offices are corrected. For this reason, if the work after the basic design is performed on the basis of this fixed drawing, inconsistencies and rework in the subsequent work are reduced.

  FIG. 3 is a flowchart showing a construction flow of the collective property according to the first embodiment of the present invention. Unlike the flowchart of FIG. 1, after the basic design drawing is created, the matching process is performed in step ST7. As described above, the matching process corrects the mismatch of the design elements based on the construction elements, and creates a definite drawing. Each of the construction design ST2, the advertisement / sales ST5, and the management ST6 is operated based on this fixed drawing.

  For this reason, each of the above-mentioned problems (1) to (6) is solved by creating the finalized drawing and working based on the finalized drawing.

  (Solution of 1) Finalized drawings are used in advertising / sales and management. Of course, the finalized drawings correct inconsistencies in the basic design drawings, so drawings used in advertising / sales and management and drawings used in actual construction (in other words, completed real estate) The building itself) is no different.

  (Solution 2) A construction design drawing is created based on a finalized drawing in which the mismatch included in the basic design drawing is corrected. For this reason, the construction design drawing reflects the design philosophy included in the basic design drawing, and the collective real estate constructed based on the construction design drawing also reflects this design philosophy. The design philosophy is planning that the owner or designer intends to give to the collective property, and it is convenient for the owner and purchaser of the collective property to maintain this design philosophy.

  (Solution 3) The construction blueprint is created based on the fixed drawing with the mismatch corrected. For this reason, the construction design drawing does not generate much correction during construction.

  (Solution 4) The construction plan is created on the basis of the confirmed drawing in which the inconsistency is corrected, and the construction is performed using this construction plan. For this reason, various problems are solved at the beginning of the construction, and the rework of the work based on inconsistency is less likely to occur in the second half of the construction. If the work is reduced, the construction cost of collective real estate will naturally decrease.

  (Solution 5) In advertising / sales, finalized drawings are used. The finalized drawings have corrected the inconsistencies in the basic design drawings, and there are few problematic differences from the collective real estate that was actually constructed (of course there are differences that occur during construction, but it is necessary for so-called purchasers) There is little difference in the elements that become). For this reason, it becomes difficult to produce the complaint with respect to inconsistency from a purchaser. If there are few claims, the owner can gain credibility, and costs such as complaints can be reduced.

  (Solution 6) In addition, since finalized drawings are used in management, the inconsistency between actual collective real estate and finalized drawings has been corrected after entering management (although there are minor differences) (There are few inconsistencies in so-called design elements), and management difficulty is reduced.

  As described above, the collective real estate construction system in Embodiment 1 can solve the problems (1) to (6) in the conventional construction.

Next, the detail of each part is demonstrated.
(Memory part)

The storage unit 2 stores a basic design drawing. Moreover, the memory | storage part 2 memorize | stores a construction element. Basic design drawings are created at design offices and architecture offices. The construction elements have been empirically accumulated in general contractors and various contractors. The storage unit 2 can provide materials necessary for the matching process in the matching unit 4 by storing them.
When the basic design drawing or the construction element is electronic data, the storage unit 2 stores it as electronic data. In this case, the storage unit 2 includes a hard disk drive, CD, DVD, semiconductor memory, optical disk, magnetic disk, tape drive, and the like. With these elements, basic design drawings, standard elements, and construction elements that are electronic data can be stored.

  When the basic design drawing or the construction element is paper data, the storage unit 2 stores them by filing or OCR. A user of the collective real estate construction system 1 in the first embodiment inputs a basic design drawing and construction elements to the storage unit 2 and outputs them.

(Extraction means)
The extraction means 3 extracts design elements from the basic design drawing. This design element becomes an element that causes inconsistency with a construction element (or a construction design drawing created based on the construction element) required in actual construction.

  The design element includes at least one of a scale, a dimension, an expression format, a device description, and a finished standard expression included in the basic design drawing. As a matter of course, the construction element also includes at least one of a scale, a dimension, an expression form, an equipment description, and a finished standard expression that are necessary for actual construction (or included in the construction design drawing). The extraction means 3 extracts at least one of these scales, dimensions, expression formats, device descriptions, and finished standard expressions from the basic design drawing.

(Scale)
The scale is a scale used in the basic design drawing. In principle, it is preferable that the scales included in the basic design drawings are the same in each part of the drawings (or in drawings of different sheets). In construction, if these scales do not match, the desired collective property will not be constructed. However, the basic design drawing is focused on clarifying the floor plan and structure, and often does not place importance on the scale of each part of the drawing or the agreement of the scales of drawings on different sheets. . This is because there are customs in design offices. For this reason, for example, in the floor plan of the basic design drawing, one room is described at a 1/1000 scale, while another room is described at a 1/800 scale. This is because, depending on the size of the room, when the room characteristics are difficult to convey, the basic design drawing gives priority to conveying the room characteristics by changing the scale.

(Size)
The dimensions are similar. In the basic design drawing, dimensions are described for each floor plan. Essentially, the dimensions listed in the basic design drawing should be correct along with the scale. However, the basic design drawing emphasizes the communication of the structure and features of the floor plan, and there are many cases where there is no actual size and the actual size because there is a custom in a design office or the like. A room in the basic design drawing is represented by an actual size of 1500 mm and a length of 15 mm (that is, the scale is 1/100). On the other hand, another room is represented by a length of 6000 mm and 50 mm (that is, the scale is 1/120). In such a case, it is difficult to determine whether the scale is inconsistent or the dimension is inconsistent.

  A user who only looks at the basic design drawing cannot grasp such inconsistency, but if the construction is carried out as it is, a problem will naturally occur. For this reason, when the construction design drawing is created, the mismatch in size and scale is corrected, but naturally, the basic design drawing and the construction design drawing are inconsistent.

  FIG. 4 is a schematic diagram showing a part of the basic design diagram in the first embodiment of the present invention. As shown in FIG. 4, the width of the room A is displayed as 5000 mm. On the other hand, the width of the room B is displayed as 6000 mm. The width of room B should be 1.2 times the width of room A. However, as is apparent from FIG. 4, this is not the case. The width of the room A and the width of the room B are substantially the same. This is a state in which the dimensions do not match the actual dimensions considering the scale. Considering the construction, inconsistencies in the scale and dimensions included in this basic design drawing are problematic. However, since the basic design drawing mainly shows the structure and features of the floor plan, there is little need to consider such fine inconsistencies. For this reason, the extraction means 3 extracts such a scale and a dimension as a design element which may become inconsistent with construction.

(Expression format)
The expression format includes at least one expression of a window, a pillar, a wall, a pipe, and a door of a collective property. In the basic design drawing of a collective property, at least one of windows, columns, walls, pipelines and doors contains important elements such as shape, size, angle, height, and position. Has features. For example, the shape of a column, the angle of a corner, and the like have a certain expression form, or have an expression form that also has a way of opening a window. Such an expression form varies depending on the contractor and also differs depending on the design office. Since the basic design drawing focuses on clearly communicating the floor plan and the characteristics of the structure, there is often little consideration for the expression form of such details.

  However, this expression format may be inconsistent with construction, and if left unattended, mistakes in construction may occur. For example, in a basic design drawing, a certain window is expressed so that both sides open, but because it is different from the contractor's expression format (because it is inconsistent), it will be constructed so that the center opens instead of both sides. Sometimes. In such a case, the construction is reworked, and the cost is adversely affected. In some cases, it also causes claims.

(Equipment explanation)
The collective real estate has equipment such as a kitchen, equipped furniture, an air conditioner, and lighting. The basic design drawing, of course, includes an indication of these expected devices. However, in the basic design, the main point is to convey the floor plan and features, and the details of such device descriptions are often not considered. In addition, the expression format of the equipment differs depending on the contractor (exterior trader, interior trader) and the equipment supplier.

  For this reason, the equipment description extracted from the basic design drawing may be inconsistent with the construction drawings used for actual construction and the equipment explanation in construction work. If this inconsistency is left as it is, it may naturally cause rework and complaints. The extraction unit 3 extracts this device description and outputs it to the matching unit 4.

(Finished standard expression)
The extraction means 3 extracts a finished standard expression from the basic design drawing as one of the design elements. The finished standard expression is an expression such as a so-called fit chart. Finished standard expressions vary depending on the design office and the contractor as well as the equipment explanation. Such various finish standard expressions can also be a cause of inconsistencies with construction plans and construction. Therefore, the extraction unit 3 extracts the finished standard expression and outputs it to the matching unit 4.

  The design elements that are at least one of the scale, dimensions, expression format, equipment description, and finished standard expression listed above are inconsistent with actual construction and completed collective real estate. It is an element that causes improperness for the purchaser. Of course, other than the elements listed here, there may be differences between the basic design drawing and the actual construction, but they are not so much as to cause problems in construction work and inappropriateness for purchasers. That is, the design element extracted by the extraction means 3 is an element that should be corrected early in the flow of construction, sales, management, etc. If the mismatch of these design elements is corrected at an early stage, problems and complaints in subsequent construction work, sales, and management are less likely to occur.

  In addition, the design elements extracted by these extraction means 3 cause inconsistencies with the construction elements (when matched with the actual construction). Therefore, the extraction unit 3 outputs the extracted design element to the matching unit 4. This is because the matching means 4 is used for correcting mismatch.

(Alignment means)
The matching means 4 detects a mismatch between the design element and the construction element, takes consistency, and creates a definite drawing.

  The matching means 4 detects the mismatch of the design elements by comparing the construction elements with the extracted design elements. Here, the construction element is an element corresponding to the design element, and is an element used in the construction design drawing or construction work. That is, if there is a mismatch between the design element and the construction element of the same concept, the basic design drawing containing the design element and the construction design drawing containing the construction element (or the real estate to be constructed) Will be different. Problems (1) to (6) when these are different are as described above.

  The construction element is based on construction conditions obtained from a construction contractor who constructs a collective real estate. The contractor is a general contractor, an equipment contractor, an exterior contractor, an interior contractor, or a related contractor for constructing the entire real estate. These contractors have construction conditions for elements such as scale and dimensions in accordance with their customs and standards. Various construction elements are determined based on the construction conditions.

  FIG. 5 is a schematic diagram showing a state in which the construction elements in Embodiment 1 of the present invention are taken into the matching means. As shown in FIG. 5, the contractor includes a contractor A, a contractor B, a contractor C, etc. (of course, there can be others) depending on the type of the contractor. Each of the construction contractor A, the construction contractor B, and the construction contractor C has a construction condition A, a construction condition B, and a construction condition C. These construction conditions A to C include representation methods and rules for construction elements used in construction, such as scales and dimensions. Together, the construction elements are determined. At this time, the construction conditions A to C are often different depending on the construction contractor.

  That is, the construction element is an element determined so as to be common from construction conditions that are different for each construction contractor. For this reason, a construction element makes the difference in each contractor common. This construction element is used in the matching means 4.

  Alternatively, the construction element may be obtained from a construction design drawing assumed in the collective real estate. The construction blueprint is created by the contractor based on the basic blueprint. Usually, since the construction design drawing is created from the basic design drawing, points that are likely to be inconsistent between the basic design drawing and the construction design drawing are accumulated empirically. By this accumulation, a construction blueprint that will be created from the basic blueprint is assumed. A construction element may be obtained from the assumed construction design drawing.

(Mismatch)
As with the design element, the construction element uses at least one of a construction plan and a scale, size, expression form, equipment description, and finished standard expression actually used in the construction. Here, the mismatch between the design element and the construction element is the mismatch between the scale of the design element and the scale of the construction element, the mismatch between the dimension of the design element and the dimension of the construction element, the expression form of the design element and the construction element. This includes at least one of inconsistency with the expression format, mismatch between the equipment description of the design element and the equipment description of the construction element, and mismatch between the standard expression of the finished design element and the finished standard expression of the construction element.

  In addition, when the construction element is based on an assumed construction plan, the scale of the basic design drawing is inconsistent with the scale of the construction design drawing, the dimension of the basic design drawing is inconsistent with the dimension of the construction design drawing, basic Inconsistency between design drawing representation format and construction design drawing representation format, basic design drawing device description and construction design drawing device description, basic design finish standard expression and construction design finish standard Including at least one inconsistency with a visual expression.

  The matching means 4 corrects these inconsistencies.

  If the mismatch is a scale, the matching means 4 corrects the mismatch at the scale of the basic design drawing. For example, when a certain part of the basic design drawing is expressed in 1/100 scale and a certain part is expressed in 1/120, the matching unit 4 re-creates a drawing or a document according to a certain scale. .

  If the mismatch is a dimension, the matching means 4 corrects the mismatch in the dimensions of the basic design drawing. For example, a certain part of the basic design drawing has dimensions described according to a certain scale. However, when the scale is an actual dimension, the size may be inconsistent. The matching means 4 corrects these inconsistencies. For example, when the size of the basic design drawing does not match the size on the drawing, the drawing of the basic design drawing is modified to match this.

  If the inconsistency is an expression format, the matching unit 4 corrects the inconsistency in the expression format. After the basic design drawing, since the construction design drawing and the construction are performed, it is preferable that the matching unit 4 corrects the expression format to the one adapted to the construction design and construction. By matching the expression format to the construction design and construction, rework in construction design and construction can be prevented. The confirmed drawing created by the matching means 4 is convenient for construction design and construction.

  For example, if the window representation format in the basic design drawing is inconsistent with the window representation format of the construction element (window representation format based on the construction design drawing or construction practice), the matching means 4 is the basic design. Match the window display format of the figure to the window format of the construction element. Of course, in the case where not only the window representation format but also the representation format of pillars, walls, pipes, doors, etc. in the basic design drawing is different from the representation format in the construction element, the matching means 4 changes the representation format to the construction element. Modify to match the expression format.

  When the inconsistency is a device description, the matching unit 4 corrects the device description of the basic design drawing so as to match the device description of the construction element. The same applies when the inconsistency is a finished standard expression. Of course, for the design elements other than those listed here, the matching unit 4 may detect the mismatch and take matching.

  The aligning means 4 corrects the mismatch as described above and creates a definite drawing. For example, the finalized drawing may be created separately from the basic design drawing, or may be created so as to modify the basic design drawing. At this time, the finalized drawing is created with objectivity.

  The finalized drawings created as described above are used in the subsequent construction design and construction.

  As described above, the collective real estate construction system 1 according to the first embodiment corrects the mismatch of the design elements included in the basic design drawing with respect to the construction elements, thereby reducing the subsequent rework and the cost reduction. Contribute.

  (Embodiment 2)

Next, a second embodiment will be described.
In the second embodiment, the use of a fixed drawing will be described.

(Use for construction plan)
The matching means 4 corrects the mismatch of the design elements included in the basic design drawing, and creates a definite drawing that is less likely to cause problems in construction design and construction. The construction design means creates a construction design drawing using this finalized drawing. FIG. 6 is a block diagram of the collective real estate construction system according to Embodiment 2 of the present invention. The construction design means 6 receives the confirmed drawing, creates and outputs a construction design drawing. The construction design means 6 may step on an automated part and a part subjected to human work by a contractor.

  The construction design drawing is a drawing including detailed information necessary for actual construction based on the basic design drawing. In the prior art, since the construction blueprint is created based on the basic blueprint, it takes a lot of trouble to correct the mismatch included in the basic blueprint. Or the construction blueprint containing the contradiction and the problem may be created without noticing the inconsistency. In the latter case, of course, after construction starts, work such as re-creating a construction design drawing or reviewing the construction plan is required, which is a reworking work.

  However, the confirmed drawing corrects the inconsistency, and if the construction design drawing is created based on the confirmed drawing, the construction design drawing does not include any contradiction or problem. For example, the final drawing corrects a contradiction between the floor plan size and the actual size included in the basic design drawing. For this reason, it is not necessary to pay consideration to the contradiction between the actual size and the actual size when creating the construction design drawing based on the finalized drawing.

  For this reason, the construction designer can create a construction design drawing simply by adding detailed information necessary for construction to the confirmed drawing. Naturally, since this construction design drawing displays the same structure as the confirmed drawing, there is no contradiction or inconsistency between the confirmed drawing and the construction design drawing. Since construction is based on this construction plan, the completed real estate is not inconsistent with the finalized drawings (there are differences that occur in so-called construction, but there are no fundamental differences in design elements) , Does not cause the buyer's complaint factor.

  In addition, each of the construction design drawings and finalized drawings is stored at the contractor's or owner's hands as necessary. There are few problems caused by this exchange.

  As described above, the collective real estate construction system 1 further includes the construction design means 6, so that the construction design drawing is created by the fixed drawing in which the mismatch is corrected. Since this construction design drawing is based on the finalized drawing, it is possible to prevent rework or trouble in construction. Naturally, the construction cost during the construction period is reduced, and the occurrence of complaints from the purchaser can also be suppressed.

(Sales drawings)
FIG. 7 is a block diagram of the collective real estate construction system according to Embodiment 2 of the present invention. A configuration in which the collective real estate construction system 1 described in the first embodiment further includes sales drawing generation means 7 is shown.

  The final drawing corrects inconsistencies in design elements included in the basic design drawing. For this reason, there is little contradiction between the finalized drawing and the finished type real estate to be constructed. There are differences that must be made in construction, but there is no contradiction in design elements. For this reason, if a sales drawing used for advertisement or sales is generated based on this finalized drawing, information that is consistent with the final finish can be provided. In other words, when an advertisement or sale is made using a sales drawing based on the finalized drawing, there is no contradiction with the completed collective real estate, and the purchaser is less likely to feel dissatisfied. If the buyer is not dissatisfied, there will be no complaints and the seller can sell with confidence.

  The sales drawing generation means 7 receives the confirmed drawing and generates a sales drawing. For example, when a price or other comment is necessary for the sales drawing, the sales drawing generation means 7 adds these elements to the finalized drawing. By this addition, a sales drawing is generated.

  In this way, because sales drawings are based on finalized drawings, there will be less inconsistency between sales drawings and actual collective real estate results. Disappear. As a result, there are merits for both the seller and the purchaser, and it is expected that the buying and selling of collective property will be activated.

(Management drawings)
FIG. 8 is a block diagram of the collective real estate construction system according to Embodiment 2 of the present invention. The collective real estate construction system 1 in FIG. 8 includes management drawing generation means 8. The management drawing generation unit 8 generates a management drawing based on the confirmed drawing.

  Collective real estate is transferred from the owner to the management company after completion of construction and sale. For this reason, after the sale, the management company is in a position to manage the real estate. In this management, it is necessary to manage not only the real estate but also the sales and mediation of the real estate that has become used real estate. In the prior art, similar to sales drawings, basic design drawings are often used as management drawings as they are.

  As described in the first embodiment, the basic design drawing has various inconsistencies in design elements depending on design practices and the like. When the management drawing is created based on the basic design drawing that has the inconsistency, the management drawing that is inconsistent with the collective real estate actually constructed is used. Of course, it may be difficult to manage collective real estate or to sell second-hand real estate using management drawings including such inconsistencies.

  The management drawing generation means 8 generates a management drawing based on the fixed drawing in which the mismatch of the design elements of the basic design drawing (this mismatch is the mismatch with the construction elements necessary for actual construction) is corrected. Generate. For this reason, the management drawing produced | generated contains almost no contradiction and inconsistency with the assembled property which was constructed. For this reason, the management company has an advantage that the difficulty in management and second-hand sales can be reduced by following this management drawing.

  As described above, various developments are made with the fixed drawings as the center, so that the conventional problems in the construction of collective real estate can be solved. As a result, the construction period and the construction cost of the collective property are reduced, which brings merit for both buying and selling. As this merit increases, the willingness to construct collective real estate increases and economic activities become more active.

  6 to 8 have been described with individual elements for convenience of explanation, the collective real estate construction system 1 has construction design means 6, sales drawing generation means 7, and management drawing generation. Of the means 8, two or more (including all of them) may be provided.

  As described above, the collective real estate construction system described in the first and second embodiments is an example for explaining the gist of the present invention, and includes modifications and alterations without departing from the gist of the present invention.
