One of the highest skyscrapers in Poland (with 50 floors and 195 meters high) Skyliner, is being built in Warsaw’s Wola district, near the Daszyński roundabout. Both the scale of the investment and the uniqueness of the solutions applied make the facility likely to become a new landmark of the Capital.
The scale of the project and related engineering challenges contributed to cooperation between the General Contractor – Warbud S.A. and experts in the field of structural health monitoring – SHM System from Krakow. The effect of the common activities is the system supervising the safety and quality of the construction works, controlling automatically selected engineering quantities and informing about threats.
The worldwide unique solution was the application of the smart EpsilonRebar sensors (DFOS technology) with a length of 17 m each to control the behaviour of the foundation piles. Thanks to the measurements carried out geometrically continuous along the entire length of the sensors, it is possible to analyze the force distribution transferred to the foundation during the erection of subsequent floors of the skyscraper. The EpsilonRebar sensors allow also for identification of the weakest cross-sections and the appeared cracks. Four fibre optic sensors installed within the Skyliner site provide data corresponding to 13,600 traditional spot strain gauges. Photography in courtesy of Warbud S.A.
