A case study of the Eurasia Tunnel, that connects the European and Asian sides of Istanbul under the Bosphorus Strait.
Grundig IP cameras are providing 24-7 surveillance of the perimeter of five construction areas. These cover feeder roads; the construction of a new underpass on the European side; overpasses and a bridge on the Asian side; and toll areas at both ends.
The German company’s IP pan tilt and zoom (PTZ) cameras are also positioned centrally in each construction site, looking outwards, for site managers to follow construction progress. A further four temporary cameras are inside the tunnel to monitor the pump stations; and two further cameras have been attached to the Tunnel Boring Machine (TBM, pictured) front and back, to monitor operation.
Ercan Tas of the installer Integral said: “Grundig cameras offer excellent reliability, provide high quality images and operate at night in low light conditions. It was important that all the cameras, including the PTZs, could withstand the harsh construction environment. Grundig is a brand we have used on other high-profile and demanding industrial applications and one we can trust. It is expected that an average of 120,000 cars and mini buses will use the tunnel each day, which should have a significant, positive impact on the environment of the city of Istanbul.”
About the tunnel
The 14.6 km long project including service roads and entrances, with a 5 km tunnel, of which 3.34 km two-story section extending below the sea bed to a depth of 106m. The tunnel is due for completion in December 2016.
The Eurasia Tunnel is 1km south of the existing Marmaray undersea railway tunnel, that opened in October 2013; and will provide an extra transport link between the two halves of Istanbul; and reduce crossing times from 100 to 15 minutes.
