In the development of construction technology of linearly extended structures at the stage work production plan the possibility to reduce the construction time and improving organizational and technological reliability, represented by the presence of different technology options for a range of works and processes usually are not considered. However, to improve the overall process the interaction of adjacent (consecutive) work packages should be taken into account. To optimize the construction process based on selecting the best technology of individual works or groups of works performance it is necessary to build appropriate organizational and technological model. As such a model of building structures an alternative network model can be used, designed specifically to find the best alternative. The proposed use of alternative networks allows receiving sufficient reservation and structural redundancy to significantly increase the organizational and technological reliability while improving economic performance.
