Construction cost assessment device, construction cost assessment method, and construction cost assessment program

Abstract

To provide a construction cost assessment device, a construction cost assessment method, and a construction cost assessment program that can carry out an assessment on the amount of money written on an estimate.SOLUTION: A construction cost assessment device comprises: a recognition unit that recognizes rows and columns in the details of estimation recorded in estimation information related to estimation of construction; a first identification unit that identifies, of the columns recognized by the recognition unit, a first column on which the estimation is written; a second identification unit that identifies, of the rows recognized by the recognition unit, a second row on which the amount of money for a specific item is written; an association unit that associates the details of an item written on a column excluding the second row identified by the second identification unit, in the first column identified by the first identification unit, with the details recorded in standard price information; and an estimation unit that estimates the assessed amount of the details of the item on the basis of the result of the association of the details of the item and the details performed by the association unit, the standard price in the standard price information, and the production rate and the markup set in advance according to the details of the construction.SELECTED DRAWING: Figure 1

Claims

1. A storage unit that stores standard price information for construction materials, standard prices of said materials, miscellaneous materials used in construction, standard miscellaneous material costs, standard labor costs related to labor performed during construction, and standard non-construction costs related to non-construction work, A recognition unit that recognizes the rows and columns of the estimate details recorded in the estimate information related to construction work estimates, A matching unit associates the amounts and strings of the row and column items recognized by the recognition unit with either materials, miscellaneous materials, labor, or non-construction work items, by referring to the standard price information stored in the storage unit and the model number dictionary in which the model numbers of materials are registered. An estimation unit estimates the assessed value of an item based on the results obtained by the correspondence unit that associates the item content with materials, miscellaneous materials, labor, and non-construction content, the standard price information for materials, standard miscellaneous material costs for miscellaneous materials, standard labor content, and standard non-construction costs stored in the memory unit, and the unit rates and multipliers set in advance according to the materials, miscellaneous materials, labor, and non-construction content. An output control unit that controls the output of each assessed value estimated by the estimation unit, A construction cost assessment device equipped with the following features.

2. When the recognition unit acquires estimate image information related to an image of a construction estimate, it estimates the rows and columns of the estimate content based on a trained model that has learned whether each pixel is near text, a horizontal line, or a vertical line, and the estimate image information. The construction cost assessment device according to claim 1.

3. The recognition unit, after estimating the rows and columns for which the estimate content has been estimated, outputs the estimated results as information in sheet format. The construction cost assessment device according to claim 1 or 2.

4. The aforementioned matching unit, if at least a portion of the item content matches any of the materials, miscellaneous materials, labor, and non-construction items in the standard price information, matches the matching item content with any of the materials, miscellaneous materials, labor, and non-construction items. A construction cost assessment device according to any one of claims 1 to 3.

5. The matching unit associates the matching item content with the multiple words if at least a portion of the item content matches a multiple word combination from any of the following: materials, miscellaneous materials, labor, and non-construction items in the standard price information. A construction cost assessment device according to any one of claims 1 to 4.

6. The aforementioned matching unit checks whether at least a portion of the item content refers to a set of keywords of expected variation strings in the item content and model number strings, checks for the presence or absence of keywords in the item content of multiple rows, and associates it with one of the materials, miscellaneous materials, labor, or non-construction content for which the logical operation result of AND and OR is true. A construction cost billing device according to any one of claims 1 to 5.

7. A computer equipped with a memory unit that stores standard price information regarding the standard price of the construction work, A recognition step that recognizes the rows and columns of the estimate details recorded in the estimate information related to the construction estimate, The recognition step involves associating the amounts and strings of the row and column items recognized by the recognition step with either materials, miscellaneous materials, labor, or non-construction work items, by referring to the standard price information stored in the storage unit and the model number dictionary in which the model numbers of materials are registered. An estimation step is performed to estimate the assessed value of the item content based on the results of associating the item content with materials, miscellaneous materials, labor, and non-construction content in the aforementioned correspondence step, the standard price information for materials, standard miscellaneous material costs for miscellaneous materials, standard labor content, and standard non-construction costs stored in the memory unit, and the unit rates and multipliers set in advance according to the materials, miscellaneous materials, labor, and non-construction content. An output control step that controls the output of each assessed value estimated by the estimation step, A method for assessing construction costs.

8. On the computer, A memory function that stores standard price information regarding the standard price of the construction work, A recognition function that recognizes the rows and columns of the estimate details recorded in the estimate information related to construction work estimates, A mapping function that associates the amounts and strings of the row and column items recognized by the recognition function with either materials, miscellaneous materials, labor, or non-construction work items by referring to the standard price information stored in the memory function and the model number dictionary in which the model numbers of materials are registered. An estimation function estimates the assessed value of an item based on the results obtained by associating item content with materials, miscellaneous materials, labor, and non-construction content using the aforementioned mapping function, the standard price of materials, standard miscellaneous material costs, standard labor content, and standard non-construction costs stored in the aforementioned memory function, and the unit costs and multipliers set in advance according to materials, miscellaneous materials, labor, and non-construction content. An output control function that controls the output of each estimated value by the estimation function, A construction cost assessment program that makes this possible.
