摘要

The research conducted on highway construction cost management has been primarily based on the perspective of owner. For example, the famous whole life cycle cost management theory is about how owners control the cost in the sections of estimation, budget estimation, budget, and final accounts. Construction cost was regarded as the duty of construction enterprises. This paper analyzed the construction cost control based on the internal data of construction enterprises, proposed a method of using the RBF neural net to predict the tendency of future construction cost, calculated the ratio between the predicted cost and the actual cost according to the field data, then analyzed the characteristics of the ratio above, such as means, variances, and confidence intervals. After that, ratios such as the ratios of next month were predicted by the use of exponential smoothing. If the predicting value was between the confidence interval, the construction cost was controllable, otherwise, the construction cost was uncontrollable. This method was verified to be feasible through its use in the Guizhou communications construction group.
