## 3 Results and Discussion  
Based on the results of the analysis of the scientific and technical literature and current legislative regulations, the main functions of the project manager were specified and grouped into a system of consolidated procedures (Figures 7-9) [38; 39; 40; 41; 42; 43; 44]. Figure 7: Consolidated procedures and functions of the project manager at the stage of pre-project preparation of a facility for construction. Part one. Figure 8: Consolidated procedures and functions of the project manager at the stage of pre-project preparation of a facility for construction. Part two. Figure 9: Consolidated procedures and functions of the project manager at the stage of design preparation for the facility to be constructed. Mathematical processing of the results of the survey enabled to determine the weighted mean limit intervals of the procedures and deviations from the standard duration of design work (Tables 1 and 2). \begin{table}
\begin{tabular}{c c c} \hline \hline
**Procedures Cipher** & **Procedues** & **Boundary Intervals of the Duration (Months)** \\ \hline P1 & Development of a construction project management plan together with the project owner & \(1\leq\mathfrak{t}_{\text{p1}}\leq 6\) \\ \hline P2 & Issuance of title documents for the land plot & \(1\leq\mathfrak{t}_{\text{p2}}\leq 4\) \\ \hline \multirow{7}{*}{P3} & Calculation of loads on engineering networks; submitting applications and obtaining technical conditions for connecting the facility to the networks of cold water supply, external firefighting, heat supply, sewage, electricity, gas supply, telephony, radio, etc. \\ \cline{2-3}  & Obtaining initial approvals and initial data. Preparation of materials, approval of architectural and urban planning solutions of the planning solutions of the facility & Preparation (control over preparation) of materials of architectural and urban planning solution (AGR/AGO) of the capital construction facility (booklet); submission of application, documents and booklet to the Committee for Architecture and Urban Planning of Moscow (Moscow Region); receipt of a certificate of approval of AGR (AGO) of the capital construction facility. \\ \cline{2-3}  & Obtaining certificates on radiation, background contamination in the soil, the absence of state nature reserves near the projected buildings, etc. \\ \hline P4 & Drafting a budget for for design and survey work & \(0.5\leq\mathfrak{t}_{\text{p4}}\leq 1.5\) \\ \hline P5 & Development of an assignment for engineering surveys & \(0.25\leq\mathfrak{t}_{\text{p5}}\leq 2\) \\ \hline P6 & Selection of an engineering survey organization (holding tenders) and entering into contracts for survey works & \(0.5\leq\mathfrak{t}_{\text{p6}}\leq 3\) \\ \hline P7 & Control (supervision) of engineering surveys & \(1.5\leq\mathfrak{t}_{\text{p7}}\leq 4\) \\ \hline P8 & Ensuring a positive opinion to be issued by state or non-state expert organizations in terms of engineering surveys & \(1\leq\mathfrak{t}_{\text{p8}}\leq 3\) \\ \hline P9 & Development of design assignment & \(0.25\leq\mathfrak{t}_{\text{p9}}\leq 2\) \\ \hline P10 & Selection of the design organization (tenders) and conclusion of agreements for design work & \(1\leq\mathfrak{t}_{\text{p10}}\leq 3\) \\ \hline P12 & Passing the state or non-state expertise in respect of design documents & \(1\leq\mathfrak{t}_{\text{p12}}\leq 3\) \\ \hline P13 & Obtaining a construction permit & \(0.66\leq\mathfrak{t}_{\text{p13}}\leq 2\) \\ \hline \hline \end{tabular}

Table 1: Boundary intervals for the duration of procedures at the stages of pre-project preparation and design development for the facilities to be constructed. Sample calculations of the weighted average value of the boundary interval of the duration of the procedure \"Development of the project management plan by the project manager together with the project owner\" are provided in Appendix A.
