Step S104: and storing the macroscopic model, the mesoscopic model and the microscopic model.
The newly added audit results are reflected from the overall, local and terminal dimensions, and the display method does not need to display all information, so that the burden of the audit results is not increased, the information can not be displayed in a missing manner, and the review is convenient.
And establishing a macroscopic model of the whole project according to the first model data, establishing a mesoscopic model of the auxiliary building according to the second model data and establishing a microscopic model of the building component according to the third model data by adopting a step-by-step modeling method. The macroscopic model, the mesoscopic model and the microscopic model form a three-level model. The construction model established based on the three layers is actually a sub-model forming a complete BIM model of the whole building construction project, and the models are mutually related and communicated with each other. The model construction information of different dimensions of each level comprises related progress, engineering quantity, safety quality indexes, cost and the like. In order to avoid the problems that information conflicts and repeated creation exist when models of different layers are easily encountered during modeling, the technical scheme of the invention adopts a step-by-step modeling method from macro to mesoscopic to micro step-by-step modeling.
After the three-level model is established, the step S200 is carried out: and compiling a construction progress plan, and linking the construction progress with the three-level model to generate a four-dimensional progress simulation. The step S200 further includes amplifying the occupation ratio until the occupation ratio is greater than 1, and comparing the occupation ratio with 1, so as to facilitate the judgment of a plurality of occupation ratios in the later period. .
Four-dimensional progress simulation is achieved by linking the progress plan file with a three-level model. The key is that the scheduling task and scheduling must be divided in sufficient detail. Activities such as previous grading, equipment approach, material approach and scaffolding require detailed partitioning. Meanwhile, the factors of space, time and the like need to be fully considered when reasonable sequence and schedule plan are compiled. The technical scheme of the invention uses Project management software to create engineering tasks, sets the relationship among all the work tasks and formulates a Gantt chart. The schedule task arrangement corresponds to the component object of the three-level model, the subdivided activities are displayed in the four-dimensional schedule simulation by using a BIM tool, the complete butt joint of the tasks, the Gantt chart and the three-level model is realized, and the whole schedule is all contents required to be displayed by the four-dimensional schedule simulation. In order to achieve better effect, animation can be added to the appearance of the component, and the task type, the playing time and the like can be set. So far, the four-dimensional progress simulation is established and completed, and the process comprises the following steps: (1) the created four-dimensional progress simulation takes day, week and month as time units, and the progress of the construction can be simulated in a positive sequence or in a negative sequence according to different time intervals, so that the progress of the whole construction is reflected vividly. (2) And the date and the finished and unfinished project amount of the current day are displayed at the upper right corner while playing, so that the project amount can be conveniently checked at any time. (3) The system updates the progress database in real time after changing the construction time and the current state, and adjusts Project progress plans. (4) Different colors on the three-dimensional model represent different processes.
The BIM technology is used as a tool, the building is used as an engineering background, the Navisthroks software is used for dynamically demonstrating the whole and local construction process and the construction site arrangement condition of the BIM model and the construction progress plan Project file of the building, the structure and the electromechanical equipment, which are established by the Revit software, and the Navisthroks software is used for establishing a corresponding four-dimensional progress simulation model. Compared with the traditional construction progress management method, the BIM-based four-dimensional progress simulation has the following characteristics: (1) the four-dimensional progress simulation can intuitively show the whole construction process, so that a three-dimensional visual platform is provided for project managers, and visual management of the construction process becomes possible. (2) The 3D parameterized model is completely butted with data in the Project file, so that the coordination of construction site management and construction progress in time and space is ensured, a Project manager is effectively helped to reasonably arrange the construction progress and the construction site arrangement, and various resources such as people, materials, machines and the like are optimally distributed according to the progress requirement. (3) The four-dimensional progress simulation can simulate the construction process of the whole project, can also simulate the construction process and progress of a complex technical scheme, realizes the visual intersection of the construction scheme, and avoids the problems of comprehension divergence, information omission and the like caused by the intersection of language characters and two-dimensional drawings. (4) By using the technology, the communication level of the building information is improved, the communication among all the participating parties is convenient, the influence of the construction project caused by information overload or information loss is reduced, the working efficiency and the management capacity of a building construction manager are improved, and a new way and a new method are created for the management of the large-scale construction project.
Step S300: and generating a plurality of sub models for the four-dimensional progress simulation, comparing the sub models with the subunits one by one, comparing the sub models in the four-dimensional progress simulation with the subunits in the project BIM model, setting a plurality of threads, simultaneously comparing a plurality of groups of corresponding sub models and subunits, and evaluating whether the construction scheme of the construction party is reasonable or not according to the ratio of the time consumption of the comparison result and the size of the four-dimensional progress simulation.
And establishing a construction task decomposition structure according to the four-dimensional progress simulation to make construction plans of different levels, and gradually adding the construction tasks and the progress plans into the construction plans according to the project content to form a four-dimensional construction simulation model.
As shown in fig. 4, step S300 includes step S301: and gradually adding construction tasks and progress plans into the construction plan according to the project content to form a four-dimensional construction simulation model of the project. The construction task and the progress plan are obtained by performing simulation analysis on construction site arrangement, mechanical equipment arrangement, construction scheme arrangement and other auxiliary projects.
After the four-dimensional progress simulation is completed, the construction project establishes a construction task decomposition structure according to a 4D-BIM system, and formulates construction plans of different levels, wherein the mesoscopic and microscopic models create custom families to represent various objects such as construction time, lines, pipelines and the like. And the BIM model created by using Revit software is led into a 4D-BIM system created by Navisvarks in an automatic association mode, wherein the one-to-one corresponding association relationship is automatically established between the construction task decomposition structure and each part of the model, and a four-dimensional construction simulation model frame is formed.
Then, step S400 is performed: and guiding the construction progress of the project according to the four-dimensional construction simulation model, and displaying each work of the construction process in a virtual building element construction process of a visual image.
Step S500: and judging the place with the occupation ratio larger than the set occupation ratio as the area to be optimized, submitting the area to be optimized to a designer, a proctoring party and a construction party for approval, generating approval results after unilateral approval, attaching a plurality of approval results beside the corresponding area to be optimized, representing, finally pushing the approval results to the designer according to the time sequence generated by the approval results, pushing the generated results first, and enabling the system to obtain the approval results obtained by the designer after pushing.
Step S600: and correspondingly optimizing and modifying the four-dimensional progress simulation, and finally finishing the adjustment of the construction scheme. Further comprising: and newly adding components, wherein each component is defined with an installation specification expression, and an auditing result positioned in the innermost layer is distributed to the installation specification expressions. The installation steps of the newly added components need to be checked, so that the checking result of the innermost layer is independently distributed, the newly added components can be prevented from being checked in a missing mode, and the inaccurate construction plan is prevented.
The traditional construction scheme is mainly based on the experience of technicians and experts, cannot be quantitatively described, cannot be intuitively compared, checked and optimized, and cannot predict the possible emergency in construction.
