Abstract

In order to overcome the low accuracy and assembly rate of the traditional construction cost estimation methods for prefabricated building, an accurate estimation method of prefabricated building construction cost based on support vector machine regression is proposed. The cost estimation indicators for prefabricated building construction are selected, and the indicators are preprocessed. The input vector for accurate cost estimation models for prefabricated building construction is determined, including prefabrication cost, assembly cost, direct cost, and indirect cost. A cost estimation model based on support vector machine regression is constructed, and Lagrange transformation is introduced for model training. The trained model is used to obtain accurate cost estimates for prefabricated building construction. The test results show that the cost estimation accuracy of the proposed method is basically maintained at around 99%, and the assembly rate is above 95%, which can ensure the cost estimation accuracy and has strong applicability.
