Abstract:
Standardized construction cost estimation models based on the regression analysis method were established, including the unit structure cost model and the water plant equipment purchase cost model, and combined with the water plant water ir take head, other types of buildings and general floor layout cost analysis and engineering construction and other expenses and reserve costs were estimated for the cost of the water plant.Acoording to the actual project, the obtained model was verified.The estimated errors of the const ruction cost of the unit structure were all controlled within 30%,which meet the accuracy of control requirements of the project proposal stage, the actual equipment purchase cost was-11.30% of the estimated error, the overallost stimation error rate of the water plant cost was only 4.03%. The cost model of the water plant based on regression analysis can be applied to estimate the cost of a water plant rapidly and ensure good estimation accuracy.
