Sažetak
Business carried out by construction companies is based on the implementation of agreed projects within the agreed cost and time limits. The contractor's estimation of a project goes through several phases. A preliminary estimate of the duration and cost of a construction is essential and is the first phase of the estimate, in fact, it is one of the most important phases considering that it is the basis for any decision concerning involvement in the potential project. The contractor’s reply to the investor regarding involvement in the potential project must be submitted on time, it must be accurate enough and with the minimum cost invested in the analysis. Analyses conducted within the research presented in this paper confirm that artificial neural networks (ANN) offer the possibility of satisfying all three criteria. That is, ANNs provide satisfactory accuracy for the preliminary estimate of the duration and cost of projects with the minimum engagement of resources to implement the above analysis.
