In the modern world, the issue of the ratio of the quality of construction technologies at oil production facilities and prices for various types of services associated with this activity is very relevant in the oil and gas sector. In this sector, there is constant competition between companies in search of the most efficient, cost-effective and innovative project. Design and survey work is a very important part of any project. Determining the cost of design and survey work is an important stage in the organization of the construction process. The contracting of design organizations takes place in a market economy, taking into account the expected quality of work, and also represents a labor-intensive process that cannot be implemented without the development of internal concepts among companies. The article will review the existing successful concepts for determining the cost of design and survey work that are used today. Also, the use of modern technologies at the stage of design and survey work can not only improve the quality of work, but also solve the cost issue.

Information models are successfully used in construction when developing archi-tectural and planning solutions, as well as when performing building elements cal-culations. Information models of organization processes and construction produc-tion technologies have not found their place in the system of BIM technologies. In this regard, the formation of approaches to the construction of information models of the processes of construction of buildings and structures should be attributed to the current issues of construction science. The main focus of the work is on the discrepancy between the processes of scheduling and determining the estimated cost in the process of preparing project documentation for construction. The pur-pose of the work was to develop the principles of building an information model for the formation of Executive documentation established by the legislation of the Russian Federation for the construction of capital construction projects. In the process of achieving the goal, the author solved the problems of systematization of problems of organizational and technological design and formulated the principles of building information models describing the process of construction of structures of buildings and structures, which are used for forming acceptance certificates. As a result of the research, the author comes to the conclusion that it is necessary to introduce the codes of the classifier of construction resources into the practice of organizational and technological design and estimate calculations. At the same time, codes of the classifier of construction resources should be applied at the stage of development of architectural planning and design solutions.

The expansion of urban space is carried out through the construction of modern multi-storey buildings located mainly on vacant sites along the perimeter of the existing urban area. It often happens that such sites were previously exposed to various man-made impacts. At the same time, man-made impacts can affect engineering and geological conditions, impairing the natural physical and mechanical properties of the bases. An example is the arrangement of various types of landfills, the movement of the soil and vegetation layer, and the artificial change in hydrogeological conditions. The construction of foundations on such soils is more complex than in normal conditions. The bearing capacity of the bases is reduced, and the geological strata are heterogeneous. The design of foundations requires the fulfilment of calculations, taking into account the above factors. The subsequent implementation of the project requires higher financial and time costs for the preparation of the bases and the construction of foundations, compared with the construction of similar buildings in conditions not previously affected by man-made effects. The article provides examples of the construction of foundations on an artificial basis, in the construction of modern multi-storey residential buildings on the territory of the former aeration fields in Lyubertsy. The results of the work are given and analyzed. The results of the study can be useful in the design and subsequent construction of modern buildings in similar conditions.

The technological design of the excavation device, as well as many other construction processes, involves the adoption of a set of decisions necessary for the effective implementation of a project. In view of the many alternative ways of developing a construction process, the question arises of the need for variant design. Variant design is a technical and economic comparison of possible ways to implement this or that building process. The formation of the most efficient fleet of earthmoving and transport vehicles for the constituent entities of the Russian Federation is a rather urgent task. Savings in estimated cost in connection with the adoption of the most effective organizational and technical decisions (hereinafter referred to as OTR) in this case for the useful life of machines varies from tens to hundreds of millions of rubles. In addition to cost savings, the solution to this problem allows you to determine the necessary volume of equipment for the engineering complex.
