The authors describe a set of measures for developing and creating of a continuous monitoring system for technical condition of the St. Petersburg Arena stadium roof structure. This stadium began operating in Saint Petersburg in late 2016. The uniqueness of the design was predetermined by the careful analysis of the measuringcontrollers arrangement in the computer model of the diagnostic object. The work describes the object under test ingeneral and the sliding roof apart, as well as the connection points of the measuring controllers sensors indicatingthe required number of them (strain gauge, inclinometer, deflection sensors, and a weather station are used). Thetechnical solutions introduced in the paper allow the transfer of monitoring results to the city's situation center, which in turn increases safety level and reduces the emergencies risks at the diagnostic site.
