Problems solved by technology

Due to the large and complex construction projects and the long construction period, the number of components in BIM is tens of thousands, and the tasks in the construction plan are also tens of thousands; therefore, the work of establishing the association between construction tasks and BIM components is becoming more and more complex, time-consuming and laborious, hindering BIM technology Application promotion
In addition, during the construction process, due to design changes, a small number of components in BIM are often added, modified, and deleted, which will bring a large number of components and construction tasks to update the relationship between them, seriously affecting the full application of BIM in construction.

Abstract

The invention provides an establishment method and system for correlation relationships between BIM components and construction tasks. Through the correlation method for setting correlation relationships between construction tasks of all stages and three common component organization structures in a BIM and then automatically generating relationships between the construction tasks and the components, a large amount of manual workload is reduced; when the components in the BIM are changed, automatic updating of the correlation relationships between the components and the tasks is supported, sothat the timeliness and accuracy of four-dimensional BIM updating are improved and the application of the BIM to the construction is facilitated.

Description

technical field [0001] The invention relates to a method and system for establishing a relationship between a BIM component and a construction task. Background technique [0002] Building Information Model (Building Information Model, BIM) is a three-dimensional digital expression of building life cycle information, known as the second technological revolution in the field of construction. BIM contains engineering information such as three-dimensional geometric models and functional characteristics of all building components in construction projects. Component is not only the basic unit of building entity, but also the most basic element in BIM. As BIM is more and more widely used in the construction stage, each component in BIM is associated with the corresponding tasks in the construction plan to form a four-dimensional BIM model, which supports three-dimensional animation simulation of the construction process according to the construction plan time, and has become a BIM...
