Sapphire, constructed by Biskon İnşaat, will be the highest building of Turkey. Biskon is using the tower cranes and construction hoists from the fleet Duramak, the rental company of Atilla Dural, in this important project. Istanbul Sapphire was completed in 2009 with the leading construction equipment in the world, preferred by Biskon İnşaat. The project, which will be completed in a very short period of time for a project of this scale, consists of 64 floors of 261-meter height, constructed on an area of 158.000 m2. Liebherr 200 EC-H 10/290 tower crane and Alimak SCANDO 20/32 TD (twin) construction hoist purchased from Atilla Dural was used in the project.
