It is about studying the construction regulations of underground facilities and engineering networks, as well as analyzing the shortcomings of foreign experience.
Keywords: Engineering, construction, technological, economic, geodetic, supervisory, activities, reactors, steam generators, Linear capital construction facilities (LOKS).
Introduction. For the construction of engineering structures and installation of technological equipment on industrial sites, a planned high-rise control is being created, consisting of the following parts (SP 126.13330.2017 "Geodetic works in construction", SP 47.13330.2012 "Engineering surveys for construction", SP 70.13330.2012 "Load-bearing and enclosing structures"): • external center control designed to ensure the design relative location of buildings and structures, stakeout of the main axes of objects under construction, engineering support networks, the production of executive surveys and geodetic deformation monitoring; • internal center network of the building (structure) on the initial and installation horizons for the construction of these buildings and structures, as well as the enlarged installation of technological equipment. Also, for step-by-step installation of technological equipment, local center networks are additionally created, taking into account the design of this equipment. The specified geodetic networks are created with an accuracy that meets the requirements of regulatory documents (SP 126.13330.2017, 47.13330.2012, 70.13330.2012), as well as documents for the installation of the technological equipment used, for example, turbine units, reactors, steam generators, etc. In some cases, the accuracy of creating networks is specified in the developed project for the production of geodetic works, while it increases at each subsequent stage of their creation (internal control).
Methods. Amendments have been made regarding the legal liability of representatives of control and supervisory authorities and construction workers. The structure has been significantly redesigned: for example, separate commissioning features residential buildings and industrial facilities, to which and Linear capital construction facilities (LOKS) are assigned, including including heating networks; removed emphasis from descriptions of working and acceptance commissions. The list of forms of acts given in the form of applications and references, but lists of documents attached to the application for extradition permits for putting the object into operation are given only in general form, without the necessary specifics, which is not typical for

In addition, important provisions, such as those relating to the need to ensure secure access for developers, building control specialists and experts to structural elements and engineering systems, were only emphasized in oral discussions and were not included in the final version of the normative document. Available scientific studies describe the documentary provision in foreign countries without taking into account the prevailing in Russia practices and regulatory requirements documents, while capturing only one very narrow area of study: work underground or in organizations of a particular type. Publications describe rights and obligations of the parties involved in any construction process. There are attempts to analyze the problems traditional for the industry from the point of view of the techno-economic approach.
Analysis and results: In a market economy, any work must begin with the approval of the balance holder object of their expediency and drawing up an investment plan, in which should be reflected: goals and objectives, technical feasibility of the project, cost and sources financing, risk analysis and other provisions. The initial data for the preparation of project documentation in the required volume, including the construction organization project (POS), specifications and estimates, serve the following documents: task for design, technical task for work, technical conditions for connection to existing heating networks, indicating the parameters at the connection point, engineering-geological and engineering-geodetic surveys. First three documents must be approved customer. The most important of them is the terms of reference for the performance of work, which indicates: initial data on the basic conditions construction; the nature of the work; specifications tracks; composition of the project (technological and design solutions and others); composition of working documentation (thermal mechanical solutions for heating networks, reinforced concrete structures, etc.); compilation guideline estimates Working with a contractor begin with the preparation of technical specifications for the implementation of construction and installation works, in which should reflect: general requirements (terms of work, payment procedure, rights and obligations parties); performance requirements works (their scope, sequence, warranty period).
Conclusion. The presented list of documents will be useful when creating new organizations, departments within existing ones. organizations, improvement and streamlining the order of work existing divisions specializing in technical supervision. The following omissions in the process of construction and installation works:
- boss workload thermal region (operational units), which does not allow a responsible approach to control over the work of the general contractor, in its turn interested in the speedy implementation of the required amount of work. The solution to this problem can be independent technical supervision;
- ignoring the need for architectural supervision;

- failure to provide documents hidden works;
- the order in which lack of funding changes are made to the working documentation during the construction process.
