Purpose: The purpose of the study is to identify the duration of the implementation and linkage between procedures and the development of a basic organizational and management model for their passage by the technical customer (developer) at the stages of pre-design and design preparation of the facility for construction. Carrying out this study is relevant, since today there is a single regulation for a technical customer (developer), describing the sequence and the possibility of paralleling and the duration of functions during the passage of procedures at the stages under consideration. Methods: The conducted research is based on the analysis of scientific and technical literature, regulatory and technical, regulatory and legal documents, the method of expert assessments is also applied. Results: The processing of the arrays of data from the questionnaire survey of experts made it possible to determine the intervals of the duration of the procedure by the technical customer (developer) and to link them with each other in time at the stages under study. As a result, a basic organizational and managerial model was developed for the passage of procedures by a technical customer (developer) at the stages of pre-design and design preparation of an object for construction. Conclusions: The use of the basic organizational and management model by organizations performing the functions of a technical customer (developer) will simplify the planning and management of processes when going through the procedures at the stages of pre-design and design preparation of an object for construction.

The article presents the results of the analysis of the modern market for the production of precast concrete products and existing technologies for their production, as well as a description of the possible method of modernization of the technological line and the production process. The main goal of the modernization is to eliminate vibrating stations and the use of self-compacting concrete mixes from the production line, which significantly increases the plant's productivity, increases the service life of molds, reduces the production time of the product and reduces financial costs.

The purpose of the study is to identify the average time parameters of the passage of procedures at the stage of pre-design and design preparation of the facility for construction. Determining the actual time spent on going through the procedures required to obtain a building permit is relevant at the present stage, since their passage is accompanied by huge time and financial costs for investors, developers, technical customers. The research is based on the method of expert assessments. The processing of the obtained data sets was carried out according to the following algorithm: correlation analysis, construction and solution of the linear regression equation, assessment of the quality of the regression equation using Fisher's F-criterion, conclusion. The processing of arrays of data from the questionnaire survey of experts made it possible to determine the average time intervals for the passage of procedures by a technical customer (developer) at the stages under study. The results for all considered procedures were summarized in a summary table. The obtained averaged time intervals will allow developers, investors, technical customers to determine the duration of implementation and rationally allocate labor and financial resources at the stages of pre-design and design preparation of facilities for construction.
