The article identifies groups of factors influencing the process of construction of buildings. The influence of the specifics of the construction of buildings is taken into account. It is established that it is necessary and sufficient to assess the specifics of the construction of buildings is to take into account the factors that have the most significant impact, namely: the influence of the tightness of the construction site; factors that complicate the transport of structures; factors that complicate the integration Assembly of structures; factors that complicate the installation of structures; factors of production technology; factors that describe the design and planning solution of buildings.

Keywords: organizational and technological scheme, parameters of the construction of the building, tightness of the construction site, factors of influence, design and planning solution of buildings

This article is focused on improving the principles and methods of assessing and planning the costs of construction projects as an integral part of organizational and technological preparation of construction. Organizational and technological preparation of construction, consists of interconnected solutions to the problems presented in the blocks and subsystems in the diagrams in the drawings. The objectives of solving such problems are described. The schemes from which we can draw a conclusion about the basic functionality and means of organizational and technological preparation of construction are presented, the most important of them are listed

Keywords: organizational and technological preparation, building parameters, duration of construction, construction factors, management scheme

The article deals with methods and models for solving expert problems that allow to avoid the possibility of negative consequences arising as a result of non-compliance with the performance indicators of the project initially set. The current state of the issue of variant study of expert situations is described. The existing mathematical models allowing to solve the majority of expert problems, irrespective of a type and level of initial information are resulted, and also the argument that the choice of a method is caused by presence and level of initial information is resulted. The algorithm of actions of the expert-Builder at the decision of a problem of an estimation of variants of design decisions of installation of special constructions is presented.
