Due to the experimental studies using the method of timing measurements, the temporal values of technological operations for the installation of modular landscaping systems were calculated and technological works that have a great influence on the total device construction time were determined. A comparative analysis of the complexity of the device layers of the used coating showed that the most time-consuming is the process of laying paving slabs -45 people-hours / 100 sq.m. (80% of the total

Technological processes and operations associated with the installation of the pavement with the use of paving slabs under pedestrian load are more labor-intensive compared to the installation of landscaping systems. The average value of the complexity of the device operating cover for pedestrian load is 56.7 people-hours / 100 sq.m., while the average value of the complexity of the device of the coating with peeling systems is 15.6 people-hours / 100 sq.m., which is 28% lower than the complexity of the device operating cover for pedestrian loading.
