ANALYSIS OF NORMATIVE LABOR CONSISTENCE OF STRENGTH-MONOLITH STRUCTURES

The work is dedicated to the study of the domestic regulatory framework for the construction of prefabricated and monolithic structures over the past 50 years. An analysis of the current regulatory documents, which serve as the basis for calculating labor intensity, machine intensity, and work costs, has been conducted. The conclusion drawn is that these regulations cannot be directly applied to prefabricated-monolithic technologies. Regulations developed for traditional technologies (monolithic and prefabricated reinforced concrete) often inadequately reflect the actual costs associated with new, more efficient solutions. In the context of prefabricated-monolithic construction, the situation is further complicated by the absence of specialized regulations. There are standards for the construction of both prefabricated and monolithic structures, but when these technologies are combined, simple summation of values often leads to an obviously overestimated assessment of time and cost. There are no specific regulations for determining the labor intensity of prefabricated-monolithic construction. Instead, separate standards exist for prefabricated and monolithic structures. Moreover, detailed regulation of prefabricated and monolithic construction was carried out 40 years ago. Since then, more productive machinery and equipment, efficient tools and instruments, and new structural and technological solutions have emerged. This often complicates the consideration of structural and technological features, leading to inaccuracies in organizational and technological modeling. With the development of the domestic cost-estimating regulatory framework, scientific and technological advancements in the construction industry are increasingly taken into account. The parameters for labor intensity and machine intensity are gradually approaching real values, but this is not true for all construction processes. Additionally, when considering only cost estimates, the exact values of labor intensity are often not critical—many companies benefit from higher estimates since a higher estimated cost is advantageous. However, inflated labor and machine intensity values lead to errors in work execution modeling. These errors quickly become apparent in practice, and for the construction of similar or repeated projects, companies establish internal standards or apply correction coefficients to existing regulations. Thus, for common construction solutions, inaccuracies in the domestic regulatory framework are adjusted based on the experience of previous projects. However, for unique projects, such adjustments are difficult due to the lack of relevant experience. Therefore, for organizational and technological modeling of prefabricated-monolithic construction, it is recommended to use the latest regulatory standards from 2023 and, if necessary, conduct multi-variant modeling based on regulatory data from the past 40 years.
