As a result of the experimental statistical modeling in the factor space \(\mathbf{\Omega_{x}}\), a model was obtained, \(\mathbf{Y_{req}}\) (5) (\(\mathbf{T_{se}}=2.918\)), describing the influence of organizational factors, such as the number of working days per week (\(\mathbf{X_{4}}\)) and the number of brigades (\(\mathbf{X_{5}}\)), as well as the degree of combination of mechanisms for carrying out high-rise work (\(\mathbf{\
u_{1}}\), \(\mathbf{\
u_{2}}\), \(\mathbf{\
u_{3}}\)

The nature of the influence of factors is indicated by the signs of the coefficients. The \"+\" sign indicates that with increasing factor value the response magnitude increases, and with the \"-\" sign, it decreases. The graphical response with isolines of the multivariate \(\mathbf{Y}_{req}\) model is presented in Figure 8.  
In this diagram, the duration function for performing facade work with insulation of the external structures of a building reaches extrema at the following points:  
\(\mathbf{Y}_{req\ min}=91\) days. at (\(\mathbf{v_{1}}=0\); \(\mathbf{v_{2}}=1\); \(\mathbf{v_{3}}=0\); \(\mathbf{X_{4}}=+1\); \(\mathbf{X_{5}}=+1\));  
\(\mathbf{Y}_{req\ max}=430\) days. at (\(\mathbf{v_{1}}=0\); \(\mathbf{v_{2}}=0\); \(\mathbf{v_{3}}=1\); \(\mathbf{X_{4}}=-1\); \(\mathbf{X_{5}}=-1\)). The duration of insulation of an elite residential building is the amount of calendar time from the beginning of the first task to the completion of the last task, taking into account the accepted technological and organizational schemes for performing the work. Analyzing the graphical representation of Model 1, the following can be observed (Figure 8). The nature of the influence of technological factors on the studied indicator changes depending on the degree of combination of work (as it decreases, the duration of isolation increases). To achieve the minimum values of the indicator \"Duration of work\" \(\mathbf{Y}_{req\ min}\), it is recommended to use a technological scheme using construction crad

Using the industrial mountaineering method increases the duration of insulation work, which leads to additional costs for construction and installation work. Thus, the desired result in terms of \"Duration of work\" is achieved when using construction cradles. The minimum duration of the external structure's insulation of the building is achieved with 100% use of cradles when the work is organized within 6 working days by three brigades. It should be noted that, as mentioned earlier, each team consists of 25 workers of different specialties. In addition, ES modeling showed the possibility of using 70 people instead of 75. The value of the \"Duration of work\" indicator, in this case, will be 91 days.
