Abstract

The quantity of a component or the entirety of a construction project can be automatically derived from the BIM model of the project. However, for this quantity to become the input data for the construction cost estimation process, it requires appropriate classification in accordance with specific regulations on construction expenses. Each country has its own encoding systems and rules for measuring quantities and making construction estimates. By analyzing the necessary information for classifying the quantity of concrete in accordance with the codes in the Vietnam Construction Norms and based on the logic of two classification systems for construction components, MasterFormat and UniFormat, the author has proposed rules for encoding concrete components in the BIM model. With the assigned codes, the quantity derived from the model is automatically classified in accordance with the Vietnam Construction Norms and is used directly in the estimation process.
Keywords: BIM, quantity take-off, element classification, element labeling, cost- estimation.
