Description

TECHNICAL FIELD

[0001] The present application relates to the field of engineering quantity statistics in infrastructure projects, and particularly relates to a rapid Revit-based forward design engineering quantity statistics method and system. BACKGROUND

[0002] In the BIM (Building Information Modeling) forward design process, the number and types of buildings are very large, and the engineering quantity statistics work is very difficult. Although the Revit (a BIM software) can be used to automatically generate an engineering quantity bill of quantities, the automatically generated bill of quantities is disordered and cannot be extracted by categories. At present, there are mainly two methods for engineering quantity statistics: (1) secondary development on the Revit platform, and application program interface (API) is used to import the BIM model into the quantity calculation software for statistics and then import it into Revit; (2) manual calculation. However, these two methods are both deviated from the essence of directly extracting engineering quantities from the information model, and in the construction drawing design process, the drawings are often modified several times, and each modification will cause the technical personnel to repeatedly calculate the quantities, resulting in low calculation efficiency and high error rate. Therefore, how to directly obtain the engineering quantities through the BIM software is the key point and difficulty in the industry, and has become a key technical problem to be solved in infrastructure projects.

[0026] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with embodiments.

[0027] As shown in the figure, the forward design quantity fast statistical method of the present embodiment based on Revit comprises: Figure 1

[0028] ​S101, Establish naming and annotation rules for components, including naming rules including material and annotation rules including structural hierarchy;

[0029] S102, Responsive modeling operation, uses Revit software to create a 3D model of the project and establishes an association between the 3D model and the naming rules of the components;

[0030] S103, responding to the material extraction operation, uses Revit software to extract the material extraction schedule as the bill of quantities;

[0031] S104, responding to statistical operations, sets filters in the bill of quantities table based on the naming and annotation rules of components, and applies the filters in the bill of quantities table to obtain the required statistical quantities.

[0032] The main material categories in engineering projects are concrete and steel. Before project modeling, material planning should be carried out, classifying the engineering materials during the civil engineering phase into concrete and steel structures, and categorizing the types using a second-level heading format. In this embodiment, the naming rule for materials in step S101 means that the name of a component consists of the material and the component ID, and the material and the component ID are connected by a preset separator. For example... Figure 2 As shown, material and component ID constitute the first-level and second-level headings, respectively, connected by a preset separator "-". The specific classification is as follows: Open the Material Browser, create a new material, and then name the new material according to the material naming principles in the table above. For example, concrete can be classified as Concrete-C20 and Concrete-C30, and steel can be classified as Steel Structure-Q235 and Steel Structure-Q345.

[0033] Following the same naming process for materials, "annotations" should also be planned in advance before the formal modeling of the project. Structures should be named according to multi-level heading rules. Specifically, the "annotation" function for identifying data is located in the attribute bar; annotations should be named according to the actual situation of the project. In this embodiment, the annotation rule containing structural levels in step S101 means that the annotation of a component consists of information from multiple structural levels of the component in the engineering project, and the information from multiple structural levels is connected by a preset separator. For example... Figure 3 The example shown is an information example with three structural levels, which are connected by a preset separator "-" for first-level headings, second-level headings, and third-level headings, such as a building - wall - first floor.

[0034] In this embodiment, step S102, establishing the association between the 3D model and the naming rules of the components, includes: naming each component in the 3D model of the project according to the naming rules including material, and adding annotations to the attributes in the attribute bar of each component in the 3D model of the project according to the annotation rules including structural hierarchy. Models in Revit software are divided into three families: system families, built-in families, and newly created families, such as...Figure 4 As shown, each component mainly includes walls, boards, columns, beams and the like, and for the above components, component material information association and annotation information association need to be configured, the material information association such as wall configuration "concrete-C20" material information, "steel structure-Q235" material information and the like, and the annotation information association contains structural levels, including engineering parts, structural types and other refined information, such as "wall-one floor" annotation information, and after the configuration is completed, the information association is completed.

[0035] In the Revit schedule creation position, "new material extraction" is selected, and through the "material extraction schedule", a material-based quantity table can be obtained. In step S103 of the embodiment, when the material extraction schedule is extracted by using the Revit software, the field selection of the material extraction schedule is in the order from top to bottom as "family and type", "material: name", "material: volume" and "annotation". Among them, "material: name" and "annotation" contain the naming and annotation rule information of the component, and "material: volume" contains the key information of the quantity (volume). For example, Figure 5 As shown, the extraction of the material extraction schedule by using the Revit software includes: after the selection of the schedule category, the setting of the field, the setting of the sorting and grouping, the setting of the format, and the setting of the appearance, the "material extraction schedule" with the required field, sorting mode, format and appearance style can be created.

[0036] In step S104, different filter configuration cases are used to extract various quantities. After opening the "filter" and inputting the "material: name" and "annotation" keywords in the "filter condition" position, all quantities of the system can be obtained according to the needs, and the quantities can be continuously refined according to the needs and the input keywords, and the concrete quantities of all walls, boards, columns and beams of a certain floor and the like can be obtained. As an optional implementation manner, in step S104 of the embodiment, when the filter is set in combination with the naming and annotation rule of the component in the quantity schedule, the filter is set as a first filter or a second filter: the filter condition of the first filter is "material: name", the logical relationship of the filter is "contains", the key word of the filter is inputted as a specified material name, the specified material name is concrete or steel structure, and all specified material quantities of the engineering project are filtered out by applying the filter; or, the filter condition of the first filter is "material: name", the logical relationship of the first filter is "contains", the key word of the first filter is inputted as a specified material name and a specified material type, the specified material name is concrete or steel structure, and the specified material type is the mark of the concrete or the model of the steel structure, so as to filter out the quantities of the specified type material of the engineering project by applying the filter; the filter condition of the second filter is "annotation", the logical relationship of the second filter is "contains", and the key word of the second filter is inputted as a specified structural level, so as to filter out the specified structural level quantities of the engineering project by applying the filter.Figure 6 For example:

[0037] Extracting concrete engineering quantity of the project: set the filter condition as "material-name", the second column as "contains", and the third column as "concrete". Then, the engineering quantity of concrete of the project can be obtained. If the concrete specific grade, such as C20, is needed to be specified, input "concrete-C20" in the third column.

[0038] Extracting steel structure engineering quantity of the project: set the filter condition as "material-name", the second column as "contains", and the third column as "steel structure". Then, the engineering quantity of steel structure of the project can be obtained. If the steel structure specific strength, such as Q235, is needed to be specified, input "steel structure-Q235" in the third column; if the steel structure specific strength and type, such as H-beam, is needed to be specified, input "steel structure-Q235-H-beam" in the third column.

[0039] Extracting all engineering quantity of the workshop: set the filter condition as "annotation", the second column as "contains", and the third column as the workshop name, such as "crushing workshop". Then, all engineering quantity of the crushing workshop can be obtained.

[0040] As another optional embodiment, in step S104, the filter is set in the engineering bill of quantities in combination with the naming and annotation rules of the component, and the filter is set as the first filter and the second filter with the logical relationship of and logic or logic: the filter condition of the first filter is "material-name", the logical relationship of the filter is "contains", the key word of the filter is inputted as the specified material name, the specified material name is concrete or steel structure, and all engineering quantity of the specified material of the project is screened by applying the filter; or, the filter condition of the first filter is "material-name", the logical relationship of the first filter is "contains", the key word of the first filter is inputted as the specified material name and the specified material type, the specified material name is concrete or steel structure, the specified material type is the grade of concrete or the model of steel structure, and the engineering quantity of the specified type of material of the project is screened by applying the filter; the filter condition of the second filter is "annotation", the logical relationship of the second filter is "contains", and the key word of the second filter is inputted as the specified structure level, so as to screen the engineering quantity of the specified structure level of the project by applying the filter. See Figure 6 For example:

[0041] Extracting concrete engineering quantity of the workshop: set the filter condition as "annotation", the second column as "contains", and the third column as the workshop name. Set the filter condition as "material-name", the second column as "contains", and the third column as "concrete". Then, all concrete engineering quantity of the crushing workshop can be obtained. Similarly, if the concrete specific grade, such as C20, is needed to be specified, input "concrete-C20" in the third column.

[0042] Extract the workshop steel structure engineering quantity: set the filter condition as "annotation", the second column as "contains", and the third column as the workshop name that needs to be counted. Set the filter condition as "material-name", the second column as "contains", and the third column as "steel structure". In this way, the engineering quantity of all steel structures in the workshop can be obtained. Similarly, if the steel structure needs to be accurate to a specific strength, such as Q235, input "steel structure-Q235" in the third column; if the steel structure needs to be accurate to a specific strength and type, such as I-beam, input "steel structure-Q235-I-beam" in the third column.

[0043] Referring to Figure 6 As another optional embodiment, step S104 further includes: classifying and counting according to the material in the component name in the bill of quantities, to obtain the total engineering quantity of each type of material in the project.

[0044] In summary, the forward design engineering quantity rapid counting method based on Revit of the present embodiment includes setting the component naming rules in the manner of multiple levels of titles; associating the three-dimensional model of the project according to the naming rules of the components; establishing the bill of quantities; and extracting various types of engineering quantities by using different filter configurations. Before creating the forward design three-dimensional model, the present embodiment method formulates the engineering material and annotation naming rules, avoids information disorder during automatic engineering quantity counting in the later stage, and facilitates filtering and screening by categories. During the creation of the Revit model, the information is associated to each system family, built-in family and newly built family according to the naming rules of the engineering material and annotation, so as to make the engineering quantity counting accurate and avoid any omission of engineering quantity. According to the project demand, the bill of quantities fields are created, so that a clear and complete engineering quantity list can be obtained according to the engineering quantity classification demand, and missing items are avoided. During the counting process, no secondary development is needed, so that the engineering quantity extraction is very simple and convenient for new people with weak foundation. According to the configuration of different filtering conditions, the engineering quantities are classified, and after the model is modified, the engineering quantities can be dynamically updated instantaneously without time-consuming repeated calculation. The forward design engineering quantity rapid counting method based on Revit of the present embodiment can realize the rapid extraction of all types of engineering quantities of Revit forward design, save the calculation time of technical personnel, improve the work efficiency, realize the classified extraction of the engineering quantities of a single building, structure or even the entire project without the need of the matching work of the budget personnel, make the Revit application simple without the need of secondary development, dynamically update the engineering quantities with the model changes, avoid frequent calculation of engineering quantities due to changes in drawings, cause the technical personnel to repeatedly rework, and improve the efficiency and accuracy of BIM forward design engineering quantity calculation.
