Making a conceptual cost estimating for a construction project using Artificial Neural Network (ANN)
Description: Historical data collected from 38 construction projects "Data in the second picture" are given
Using this data, you are required to estimate total cost of a 12 story 17,350 m2 (total area) office building
that is planned to be constructed
in 2020. Location Index for the office building is 1.07, Quality Index is 3, and Construction Methods
Index is 1.1 with ANN.
Required:
*) Details of all ANN model(s): The number of hidden layers, neurons in each layer, transfer
function in each layer, training function, weight/bias learning function, and performance function.
*) Your total cost estimate for the office project.
*) And a brief discussion about how accurate is your estimate.
