Application Analysis of Engineering Cost Combined with Building Engineering Structure Design
In the key structural design stage in the early stage of engineering construction project,cost prediction is an important reference to measure the feasibility of the project,to provide the evaluation basis for project de-cision makers,and to analyze the application of engineering cost in the structural design of construction engi-neering.The cost influence index of the engineering structure design stage is selected,a set of index system that can reflect the characteristics of building engineering structure is established,the structural design data of con-struction engineering is mined and preprocessed as the model input,and the engineering cost prediction model is constructed based on BP neural network.The example application results show that the root mean square error of the project cost prediction model is 10-4 and the average relative error is 1.82%,which proves that the model has a good application effect in the project cost prediction in the design stage of construction structure.
