objects and systems that is successfully used and developed in almost all fields of science, technology and industry is computer aided design building information modelling – BIM. In structural terms BIM is an organizational and technical system consisting of a large number of interrelated and interacting components. The main function of BIM is to carry out object aided design and their components through the use of mathematical models and other automated design procedures and computer technology. So, transition to optimization design methods will help to improve the overall ecological and economic efficiency of drainage reclamation, especially in working out new construction, reconstruction and modernization of irrigation and drainage systems.
