Is Towers as a major component of İstanbul’s silhouette today, represented for many years, the distinction of being the tallest structure in Turkey and the region. Moreover, they were the “Most Intelligent Building” of their time with an automation system controlling a total of 42,000 points of 23,000 digital and 19,000 analogues. Today’s Pro^GE exe¬cutives, beside learning that high rise buildings in contrary to suppositions, require a different accumulation of know¬ledge, gained their first experience on high-rise building construction in this important project with contributions of Turner technical staff.

Location in the city center, of the project which was harbo¬ring various technical innovations like the panel facade system practiced for the first time in Turkey, has brought along with peculiar difficulties adversely affecting the cons¬truction activities. Administrative restrictions particularly the traffic restrictions, difficulties of stocking and installation created by limited mobilization area had been surmounted by correctly identified construction methods, carefully mo¬nitored and updated construction programs.

The story of İş Towers, with its highest quality of cons¬truction achieved beside its construction period which can be considered as a record, therewithal is the story of a con¬temporary and professional mutual working environment established by the employer, design groups, main contractor and subcontractors to actualize this important project.
