Background
With the development of the building engineering industry, the traditional handicraft industry building mode (such as a cast-in-place mode) has more building quality problems due to complex working procedures, large manual demand, disordered management, resource waste, high noise, long construction period, serious environmental pollution, high building energy consumption and uncontrollable building quality. The assembly type building mode, namely the integration of design, manufacture and assembly (construction), can effectively avoid the problems and is widely applied to the building industry.
The assembly type building is a building mode which is formed by assembling component products in a reliable connection mode on a construction site, and has the characteristics of design standardization, production industrialization, construction assembly, decoration integration, management informatization and the like. Fabricated buildings include various types of prefabricated concrete structures, steel structures, wood structures, and hybrid structures. Fabricated buildings are a significant revolution in the way they are built.
The limit design method adopted by the existing assembly type building determines the limit design value of each specialty by utilizing reverse reasoning according to the total investment and each professional weight set by subjective experience. And then calculating the approximate calculation of each specialty of the to-be-limited design building engineering based on the traditional engineering approximate calculation method. When each professional estimate is greater than the corresponding design limit, the design plan is adjusted until each professional estimate is not greater than the corresponding design limit. The professional weights determined according to subjective experience have larger deviation from the actual engineering, and the accuracy of the calculated quota target value is lower. In addition, the general calculation of the traditional fabricated building generally adopts a rating pricing method or a list pricing method directly, namely the assembly rate is considered by adding hundreds of yuan to the whole project according to the cast-in-place calculation, because the casting mode and the fabricated consumption cost are different, if the whole project is calculated according to the cast-in-place mode, the method has the advantages of large calculation amount, large deviation between the general calculation value and the actual project total cost, easy occurrence of the phenomenon that the settlement exceeds the budget and low accuracy.

s101: and calculating the weight values of all the major properties of the construction project installation cost by using an information entropy method based on the historical construction cost database.
The historical project cost database is constructed in advance according to the building parameter information and cost information of a plurality of building projects with the same type as the to-be-limited design building project. The method comprises the steps of collecting relevant information of a plurality of historical engineering projects (for example, the to-be-limited designed building project is a residential building, and then the historical engineering projects can be a plurality of residential building construction projects in the same or similar geographic environment) which are the same as or similar to the type of the current to-be-approximated assembled building engineering project, for example, key data information of design engineering projects such as some self parameters (the overall layout (height, floor and foundation) of each building, hydropower layout and routing, building installation cost), total investment rating, expense items and material items such as manpower, materials and machinery and the like, and establishing a construction cost database based on any existing database model establishing method according to the key data information, wherein the implementation of the method does not influence the application.
The construction project installation cost is called construction and installation cost for short, all the specialties of the construction and installation cost comprise civil engineering specialties, water supply and drainage specialties, fire control specialties, strong electric projects, weak electric projects, heating and ventilation and the like, all the specialties of the construction and installation cost can be determined according to the existing professional knowledge and the actual conditions of the project at present, and the construction and installation cost is not limited in any way in the application.
In addition, when calculating the weight values of each professional of the construction and safety fee based on the historical construction cost database by using the information entropy method, the characteristics of the project to be designed in terms of the limit also need to be combined, that is, the structural form of the current construction project, such as a steel structure, a shear wall structure, a frame structure and the like, and the location of the project needs to be combined.
Optionally, the collected data information may be standardized first, and then information entropies of various specialties such as civil engineering, water supply and sewerage, fire fighting, and electrical engineering are calculated to obtain corresponding weight values of the various specialties.
The method has the advantages that the information entropy method is introduced into the determination of the quota design target value, compared with the conventional method for determining the professional quota design value based on the reverse reasoning method, the method can more objectively determine the weight of the cost of each professional quota design, and further determine the professional quota target value according to the construction and safety fee.
S102: and calculating the quota target value of each specialty according to the weight value of each specialty and the target investment quota of the construction project to be quota designed.
The target investment limit may be a total investment limit for a design construction project to be limited adjusted according to a preset ratio. The total investment limit is a total investment value of the whole to-be-limited designed building project, the building project is generally subjected to estimation, approximation and budget, and in the approximation stage, the total investment limit is generally reduced by a certain proportion to calculate each professional limit value, for example, the target investment limit can be calculated according to the following formula:
B＝A-A*α％；
wherein B is the target investment limit, A is the total investment limit, and alpha% is a preset proportion.
α may be, for example, 15, but of course, may be adjusted according to other methods, which do not affect the implementation of the present application.
S103: and respectively calculating professional approximate values according to the design scheme of the to-be-limited designed building project, wherein the civil engineering professional approximate values comprise the cost of the prefabricated components of the assembled part, the node cost of the assembled part and the cast-in-place part and the cost of the cast-in-place part of the to-be-limited designed building project.
When calculating the general values of construction and safety fees according to the design scheme of the construction project to be limited, the general values of the construction and safety fees for water supply and drainage, fire protection, electricity, decoration and other industries (other construction and safety professionals except the civil engineering specialty) can be calculated according to any one of the calculation methods in the prior art, and the calculation method does not influence the implementation of the method.
The civil engineering professional cost is taken as an important component of the construction and security cost, and the control of the construction and security cost is very important. In the calculation of the approximate value of the civil engineering professional cost, the following description of the implementation mode can be referred to.
Because the cost consumption of the assembled part is different from that of the cast-in-situ part, and the nodes of the assembled part and the cast-in-situ part are different from the materials used by the assembled part and the non-assembled part, and the connection between the prefabricated member and the cast-in-place member is complex, and the cost is more, so when the cost of the construction engineering is calculated, the whole fabricated construction can be divided into a fabricated part (including nodes of cast-in-place members and prefabricated members) and a non-fabricated part, i.e. a cast-in-place part, the costs of the various sections, which may include, for example, cast-in-place columns, cast-in-place beams, cast-in-place walls, masonry walls, cast-in-place slabs, etc., are then calculated in turn, taking into account that the foundation section of the construction project is important to the safety of the entire building, that section of the foundation of the fabricated building is not fabricated, the base part can be calculated as a large component in the non-assembly part when calculating the cost. The fabricated part is a prefabricated part, and can comprise prefabricated columns, prefabricated beams, prefabricated walls, prefabricated plates, other prefabricated components and the like.
When the cost of each part is calculated, the implementation process of calculating the approximate value of each specialty according to the building cost in the prior art can be referred to, and details are not repeated here.
S104: judging whether the approximate value of each specialty is larger than the corresponding quota target value, if so, executing S105; if not, the process is ended.
S105: the design is adjusted until the approximate value of each specialty is less than the corresponding quota target value.
And when the approximate value of each specialty is not more than the corresponding quota target value, the current design scheme of the construction engineering is proved to meet the requirement of the total investment of the project, and the original design scheme is not changed.
When the approximate value of each specialty is larger than the corresponding quota target value, the requirement that the current design scheme of the construction project does not meet the total investment of the project may be caused by the approximate calculation and the budget over the approximate calculation, and the original design scheme needs to be adjusted. And continuously judging whether the adjusted design scheme is not larger than the corresponding quota target value or not, and if the adjusted design scheme is not larger than the corresponding quota target value, carrying out scheme adjustment until the calculated professional approximate values are not larger than the corresponding quota target values. The design scheme of the limit design value can be optimized by assisting the owner and the design institute, and the design adjustment and coordination between the building and the structure can be realized, so that the design scheme meeting the limit design value can be obtained.
In the technical scheme provided by the embodiment of the invention, when the civil engineering cost of the project to be limited is calculated, the assembled part and the unassembled part are calculated separately, and the nodes of the assembled part and the unassembled part are taken as a large component to be calculated separately, so that the problem that the accuracy is lower when the whole is calculated according to a cast-in-place mode due to different consumption costs of the assembled part, the cast-in-place part and the nodes is solved, the accuracy of the calculation of the project to be limited is improved, the phenomenon that settlement exceeds budget and the probability of the occurrence of budget exceeding approximate calculation are reduced, whether the design scheme meets the requirement of the total project investment is effectively, accurately and quickly judged, and when the approximate calculation of the project is calculated, the method not only has good compatibility with the existing approximate calculation method, is easy to improve on the basis of the existing approximate calculation method, but also greatly improves the calculation speed of the approximate calculation of the project, the method is beneficial to realizing the accurate control of the quota design and the cost of the whole engineering project.
Optionally, in order to quickly and conveniently count the types and the number of the components and the nodes of the assembled type building engineering (the assembled type part and the cast-in-situ type part, and the subsequent management, the BIM three-dimensional model of the architectural engineering to be designed with the limit can be established based on the BIM platform according to the design scheme of the architectural engineering to be designed with the limit, the assembled parts and the unassembled parts in the BIM three-dimensional model can be classified according to the components and the nodes and coded, and the coding can facilitate the statistics of the number of the nodes and the components, and optionally, when coding, it can set multiple layers of coding information, such as the first level coding information for distinguishing the component and the node, the second level coding information for distinguishing different types, and the third level coding information can be the number of the component.
In another embodiment, a unique identification information (for example, a two-dimensional code or a bar code) may be set for each component or node by combining with an RFID technology and an NFC technology, where the identification information includes identification information and location information of the component, and the identification information may include key information such as a name and a function of the component, so that each component may be classified and counted according to the identification information. In addition, by recording the production key information of the prefabricated parts, the production quality and the production progress of the prefabricated parts are traced and managed, the production automation and the production intellectualization are realized, and the production method has obvious effects of reducing labor and improving the production quality and the production efficiency.
When calculating the cost of each part of the designed building project to be limited, please refer to fig. 2, the calculation can be performed according to the following method:
determining an assembly type part and a non-assembly type part of the constructional engineering to be designed according to the design scheme;
the non-fabricated part calculates the cost according to a cast-in-place approximate calculation method, and the cost is used as the cost of the cast-in-place part. That is, the non-assembly type part (cast-in-place part) can be calculated according to the existing calculation method for calculating the cost of the cast-in-place part, and the detailed description is omitted here.
For example, the types of components and the number of the non-assembled parts may be counted; calculating the reinforcement ratio, the type and the number of templates, the concrete consumption and the reinforcing steel bar material consumption of the component according to the size, the area, the position information and the function of the component; and calculating the cost of each type of component according to the corresponding reinforcement ratio, the type and the number of the templates, the concrete consumption and the reinforcing steel bar material consumption of each type of component.
And counting the types and the number of prefabricated parts contained in the assembled part, and calculating the cost of the assembled part according to the preset cost and the number of the prefabricated parts of each type to serve as the cost of the prefabricated parts. Aiming at the assembled part, the components need to be prepared in advance, and the prefabrication cost of each type of component is not greatly different, so that the market prices of various components can be calculated in advance or obtained according to market research, and the market prices can be stored in a system and directly called during calculation. Specifically, in order to predict the cost accuracy of each prefabricated part, each type of prefabricated part can be further secondarily classified according to the function of the prefabricated part; and then calculating the cost of the fabricated part according to the preset cost and the number of the prefabricated parts corresponding to each function. For example, the prefabricated columns are divided into prefabricated frame columns and prefabricated shear wall hidden columns, the prefabricated beams are divided into prefabricated frame beams and prefabricated superposed beams, and the prefabricated walls are divided into prefabricated inner walls and prefabricated outer walls; the prefabricated slab is divided into a prefabricated laminated slab, a prefabricated balcony slab and the like.
When the cost of each part is calculated, a traditional cost calculation method can be combined, and a system for the cost of the assembly type building component is established according to the material list item cost (steel bars, concrete, heat insulation layers, embedded parts (assembly type parts), templates and the like) and the cost list item cost (labor cost, material cost, machine shift use cost, enterprise management cost, measure cost, profit and the like).
And counting the node types and the number of the assembled parts and the non-assembled parts, and calculating the node cost according to the preset cost and the number of the nodes of each type.
The node of the prefabricated member and the cast-in-place member can be used as a large member for calculation, and the nodes of different prefabricated members and cast-in-place members are naturally different, so that the cost required by each type of node can be calculated in advance and stored by combining the corresponding process, the used materials and other expenses, and the like, and then the calculation is directly carried out.
Certainly, when the node cost and the prefabricated part cost are calculated, the reinforcement ratio, the type and the number of the templates, the concrete consumption and the reinforcing steel bar material consumption of the member can also be calculated according to the size, the area and the functions of the member; and calculating the cost of each type of component according to the corresponding reinforcement ratio, the type and the number of the templates, the concrete consumption and the reinforcing steel bar material consumption of each type of component.
Considering that the operation period of the process project is long, the material list and the cost list fluctuate in different seasons and different periods, the cost information of each component stored in the system can be periodically updated, so that the calculation accuracy of the cost of the whole cost building project is further improved, and the accurate control and the quota design of the cost of the whole project are further facilitated.
