Use of artificial intelligence for estimating cost of integral bridges

Estimation of costs is important in every phase realisation construction projects. However, the influence cost estimation highest early phases as it then that decision about accepting job or withdrawing from project made. The quantity data available initial smaller compared to subsequent phases, which affects accuracy such phases. A research making use artificial intelligence estimate integral road bridges presented paper. model prepared by means neural networks. best network has proven be highly accurate based on mean absolute error, amounts 13.40 %.
