Problems solved by technology

The traditional way to deal with project changes is to calculate and process the impact of changes by manually changing the BIM model and related parameter settings. Such a change update method can only reflect the changes in the style and appearance of the design scheme in the model, but cannot reflect the changes in the design scheme. The impact of changes on cost, schedule, etc.

Embodiment Construction

[0026] The specific implementation of a method for quickly changing a BIM model of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] A method for quickly changing a BIM model of the present invention specifically comprises the following steps: step (1), decomposing the BIM model into work packages, reading the model graphic element entity information in the work package, and obtaining material and geometric attributes; step (2) 1. Generate the bill of quantities according to the engineering quantity calculation rules; wherein, the engineering quantity calculation rules include the definition of statistical units, statistical algorithms, and data categories; step (3), based on the engineering quantity bill, according to the defined labor quota , the logical constraint relationship between processes, and the constraints of total resources to calculate the labor time and establish a schedule.

[0028] Such as figure 1...

Abstract

The invention provides a BIM (Building Information Modeling) rapid changing method, which comprises the following steps of decomposing a BIM into a work package, reading model primitive entity information in the work package, and obtaining a material and a geometric attribute; generating an engineering quantity list according to an engineering quantity calculation rule, wherein the engineering quantity calculation rule comprises definitions of a statistical unit, a statistical algorithm and a data category; and on the basis of the bill of quantities, calculating the labor time according to thedefined labor quota, the logical constraint relationship between the processes and the constraint condition of the total resources, and establishing a progress plan. According to the method, the change content is embodied on the model, and meanwhile, the change of the engineering quantity, the cost, the progress and the like generated by change can be directly obtained.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional modeling of substations, in particular to a method for quickly changing a BIM model. Background technique [0002] In recent years, with the rapid development of housing and basic buildings in our country, engineering construction requires a green, energy-saving, efficient and sustainable development path from the planning and construction period. With the help of information technology as a tool to realize the information construction of construction enterprises, refine management, improve project management level, and improve project management efficiency have always been the focus and goal of construction enterprises. However, in this upsurge, as the application of information technology continues to deepen, the depth of technology application is also continuously strengthened. Comprehensive planning and top-level design, project information processing, project centralized management...
