The current legislative acts and regulatory and technical documents defining the requirements for the organization of the customer's activities are considered in the work. A review of studies with different approaches to the formation of organizational structures of the customer, depending on the types of construction, their volumes and features of objects, is carried out. The factors determining the requirements for the formation of organizational structures of the customer for various objects are highlighted.

Keywords: construction organization, technical customer, organizational structure, construction control, project approach

The paper considers the modern principles of the organization of the technical customer service. The disadvantages of the existing system of forming the structure of the technical customer are indicated.

Are given the results of studies on the creation of samouplotnyayushchikhsya fine-grained fibrobetonov on the withdrawals of lithotrity with the application of a polyfunctional additive D -5. Are developed the compositions of samouplotnyayushchikhsya fine-grained fibrobetonov with the application of a basaltic fibre, which make it possible to considerably decrease the expenditure of cement and to improve the characteristics of fine-grained concrete mixture and concrete. The use of a polyfunctional additive D -5 in the mixtures makes it possible to increase the strength properties of fine-grained fibrobetonov with a simultaneous improvement in the rheological characteristics of concrete mixtures. The replacement of cement to 10 % from the mass by ashes of fraction d0,14 mm in the fine-grained concrete mixtures does not cause noticeable reduction in the strength properties of concrete. Developed samouplotnyayushchiesya fine-grained fibrobetony possess the increased strength properties and have low prime cost due to the use of local raw material and withdrawals of lithotrity
