Savcor delivered a permanent monitoring system for Zenit Stadium’s roof structure. Zenit Stadium is a modern football stadium constructed for FIFA World Cup 2018. The modern design of the stadium roof allows its opening and closing according to the weather conditions. The roof is held up by pylons and cables supporting them.
Savcor supplied a mobile monitoring system already in 2014 for the construction stage monitoring and in 2017 the system was expanded for permanent use.
New Mariinsky Theater in Saint Petersburg, Russia. The 8000 sqm building ranks among the most expensive cultural projects ever built. As the theater is built on soft marshland, it is supported by columns driven all the way to the solid ground. In order to detect any movement, the whole structure is heavily instrumented with Savcor OHM system.
The structural health monitoring System consists of 338 electrical and optical sensors detecting strain, displacement and inclination.
The Golden Horn Bridge in Vladivostok, Far East of Russia, spans 737 meters across the Golden Horn Bay in the center of Vladivostok city and has the total length of 1389 meters. Pylons are 252 meters high.
Savcor OHM system monitors this top-class cable-stayed bridge securing its structural safety and prolonging the asset's life. Online system monitors strain, tilt, vibration, GNSS displacement, weather data with wind speed and direction, air pressure, temperature and precipitation.
Online Structural Health Monitoring for a cable-stayed bridge
The cable stayed Crusell Bridge in Helsinki, utilizes the newest technology in all phases. It was a pilot project in using Building Information Modeling (BIM) technology in design, construction and monitoring as part of maintenance of the bridge.
In order to develop modern maintenance scheme, an intelligent monitoring system was designed by Savcor. Online Health Monitoring (OHM) system has been tested by loading tests and the comprehensive test results have been compared with the theoretical calculation analysis. The results verified the design and gave designers guidelines to specify the alarming limits to the monitoring system.
The Crusell Bridge monitoring system is a mix of electric, electrochemical and fibre optical sensors. The electric sensors include 3-axis accelerometers, boltable strain sensors, displacement sensors, a weather station and the cameras. The electrochemical sensors are used in two corrosion measurement fields. Majority of the sensors are Fiber Bragg Grating (FBG) strain sensors with the adjacent temperature compensation sensors.
Structural Health Monitoring for a cable-stayed bridge, Vietnam
Savcor supplied a structural health monitoring system, Savcor OHM, for the RAO II Bridge located in Hai Phong, Vietnam. The bridge iscable-stayed with a total length of 240 meters and the main span is 120 meters. The RAO II bridge was opened for traffic in late 2011. Savcor delivered real-time monitoring system hardware, software, installation of the system and training. The monitoring system consists of weldable strain gauges, accelerometers, long range displacement sensors, temperature sensors, relative humidity sensors, a weather station and the traffic cameras.
Structural Health Monitoring for two cable-stayed bridges, Russia
Savcor supplied Structural Health Monitoring systems for the Neva Cable-Stayed Bridges, an unique all steel twin bridge structure with the main span of 382 m in St. Petersburg, Russia. This bridge consists of two identical cable-stayed structures, built side by side. The first of the twin bridges was completed in 2004 while the second bridge was opened in 2008.
