Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-3 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The memory stores program of BIM software, which may be but not limited to Revit software, and also stores computer program executable by the processor for implementing project cost control method based on BIM technology.
The embodiment of the application discloses a project cost control method based on BIM technology, and with reference to figure 1, the project cost control method comprises the following steps:
s1: and generating a three-dimensional model of the target project according to the construction drawing, and dividing the three-dimensional model into a plurality of subentry models according to the construction plan.
Specifically, for example, during building construction, a three-dimensional model of a target project is generated in the BIM software according to the overall construction information of the column, the wall, the door and window position, and the outer vertical surface in the construction drawing, and the corresponding information such as the elevation, the floor height, and the dimensions of the members. When a bridge is constructed, a three-dimensional model of a target project is generated in BIM software according to information such as bridge piers, bridge abutments and bearing platforms in a construction drawing, corresponding elevations, bridge heights and sizes of components.
For example, in building a house, the construction plan is to build a bedroom first, then a bathroom and a balcony, and then, in the three-dimensional model of the house, the three-dimensional model is divided into a bedroom itemized model, a bathroom itemized model and a balcony itemized model.
S2: and acquiring the engineering quantity of the component in the subentry model, and calculating the preset cost of the subentry model according to the unit price of the component.
Specifically, the preset cost of the subentry model can be calculated by counting the number of materials used in the subentry model and the unit price of the materials used. For example, when a living room is built, the number of the required wallboards is 10, the price of each wallboard is 900 yuan, and the preset cost of the living room is 9000 yuan.
S3: and acquiring construction information, and marking the corresponding itemized model according to the construction information.
Specifically, the construction information is the construction progress, the construction photo of the construction site is obtained, then the construction photo is processed through a relatively mature image processing technology in the prior art, so that the corresponding target building in the construction photo is extracted, the proportion of the target building is adjusted to be consistent with that of the model, the target building is compared with the three-dimensional model, and the overall construction progress is further obtained.
By comparing the target building with the three-dimensional model, which itemized models are already constructed, which itemized models are under construction and which itemized models are not under construction can be obtained, and the constructed and under-construction itemized models are marked. For example, when a bridge is constructed, the three-dimensional model of the bridge comprises a bridge pier subentry model, a bridge abutment subentry model and a cushion cap subentry model; the integral color of the original three-dimensional model is gray, wherein a bearing platform can be obtained through a construction picture on site to complete construction, a bridge pier is under construction, the color of the bearing platform is green, the color of the bridge pier is yellow, the color of the bridge platform is still gray in the three-dimensional model, and the color is displayed in a distinguishing mode through different colors, so that a worker can conveniently know the actual construction progress from the three-dimensional model.
S4: and acquiring the construction member information and the comprehensive unit price of the project list, and calculating the construction cost of the subentry model.
Specifically, the component information includes the type, material and size of the component, and the item list includes the list code, the item name, the component amount, the measurement unit and the component feature description. For example, types of members in building construction include wall panel members for the construction of bedrooms, balcony members for the construction of balconies, and toilet members for the construction of toilets.
S5: and if the variance between the construction cost and the preset cost is greater than a first threshold value, sending early warning information to the client.
Specifically, the client may be a mobile phone, a tablet computer, a laptop computer, or a desktop computer. For example, when the client is a mobile phone, the mobile phone is started to the mobile phone of the responsible person in a short message manner to remind the responsible person.
The first threshold may be set according to actual conditions, and in this embodiment, the first threshold is equal to the preset cost × 8%. For example, if the preset cost is 10000 yuan, the first threshold value is 10000 × 8% — 800, if the actual cost is 10070 yuan, the variance between the construction cost and the preset cost is 10070-; if the actual cost is 9800, the variance between the construction cost and the preset cost is 9800 and 10000 is-200, and-200 <800, the early warning information is not sent; if the actual cost is 12000, the variance between the construction cost and the preset cost is 12000 and 10000 is-2000, and 2000 is more than 800, the early warning information of the excessive advance is sent to the mobile phone of the responsible person.
Referring to fig. 2, after step S4, that is, after acquiring the information of the constructed components and the comprehensive unit price of the project list and calculating the construction cost of the itemized model, the method further includes the following steps:
s6: the type, material and dimensions of the component are obtained.
Specifically, by selling the information of the document and inputting the corresponding information of the member into the server, for example, the material of the wall plate member is concrete, and the size is 3 meters by 4 meters.
S7: and obtaining a weight set to which the component belongs by a table look-up mode according to the type, the material and the size of the component.
Specifically, the weight set is a set of numerical values of the weight of a certain member, and the normal weight of the member is actually measured and stored in the form of a number set. For example, if the dimensions of a 3 m x 4 m wallboard element, the material of which is concrete, are 1560kg, 1553kg, 1565kg, respectively, the normal weight of the wallboard element is (1553, 1560, 1565); a wall panel element of 5 x 6 m size, the material of the wall panel element being concrete, the normal weight of the wall panel element being 3130kg, 3139kg, 3125kg, respectively, the weight aggregate of the wall panel elements being (3125, 3130, 3139); balcony members of dimensions 2 m x 3 m, the material of which is concrete, the normal weight of which is 1360kg, 1352kg, 1365kg, respectively, the weight of the wall panel members then being (1352, 1360, 1365) in total.
S8: and acquiring the actual weight of the component, calculating the deviation between the actual weight and the weight set, and if the deviation is greater than a second threshold value, sending alarm information to the client.
Specifically, during on-site construction, the hoisting equipment is used for hoisting the component, the component is weighed through the weighing device on the hoisting equipment so as to obtain the actual weight of the component, and the actual weight is sent to the server. The construction position of the component is obtained by obtaining a construction photo of a construction site, and the type, material and size of the component at the construction position can be obtained according to a construction drawing.
Optionally, in step S8, the calculating the deviation between the actual weight and the weight set includes the following sub-steps:
s81: in particular, the variance is a positive integer, the second threshold is set to 500, e.g., the set of weights for wallboard component A is (1553, 1560, 1565), the actual weight for wallboard component A is 1550kg, and the variance for wallboard component A is [ (1550-2+(1550-1560)2+(1550-1565)2]111, wherein 111<500, no alarm information is sent. If the actual weight of the wallboard member B is 1510kg, the variance of the wallboard member B is [ (1510-2+(1510-1560)2+(1510-1565)2]And 3, 5357 and 5357 is more than 500, sending alarm information that the weight of the component is abnormal to the client.
Optionally, in step S8, after sending the warning message to the client if the deviation is greater than the second threshold, the method further includes the following steps:
s82: if the deviation is less than the second threshold and the actual weight is different from the values in the weight set, the actual weight is added to the weight set until the number of values in the weight set is greater than the predetermined number.
Specifically, for example, the second threshold is set to 500, for example, the weight set of the wall plate members is (1553, 1560, 1565), the actual weight of the wall plate member a is 1550kg, and the variance of the wall plate member a is [ (1550-2+(1550-1560)2+(1550-1565)2]111, wherein 111<500 and 1550 is different from 1553, 1560, 1565, then take 1550 into the weight set of wallboard component a, update the weight set of wallboard component a to (1550, 1553, 1560, 1565); the actual weight of the wallboard member B is 1550kg, and the variance of the wallboard member B is 1550-2+(1550-1553)2+(1550-1560)2+(1550-1565)2]83, wherein 83<500, but 1550 is already in the weight set, so 1550 is no longer added to the weight set of the wallboard member.
For example, if the predetermined number is 3, the weight set of wallboard members is (1550, 1553, 1560, 1565), the weight set already has 4 values, and no value is subsequently added to the weight set.
Optionally, in step S2, acquiring the engineering quantity of the component in the polynomial model, and calculating the preset cost of the polynomial model according to the unit price of the component, includes:

And identifying contract information in real time to determine that the three-dimensional model of the current version is matched with the current latest contract, identifying the cost information and the variable quantity of the updated component if the three-dimensional model of the current version is not matched with the current latest contract, and updating the preset cost of the item model.
