공종별 공사비와 영향요인의 상관도 분석을 통한 건축 공사비 예측 성능 분석

Abstract

Although effectively managing construction costs is crucial for large-scale and high-rise con struction projects, achieving efficiency and accuracy can be challenging. To improve the accu racy of the construction cost prediction model, this study presents an optimal combination of influential factors based on a correlation analysis of construction costs by type. The study estab lishes five models, including the top three models and the total area obtained through correla tion analysis for each construction type, and utilizes the artificial neural network method to predict construction costs and compare the predictive performance of each model. Analysis shows that the combination of factors with vertical characteristics of the building yields a lower average error rate than other influencing factors. This finding is expected to help improve the combination of influencing factors for construction cost prediction models in future studies.
