2015–2016. The loan was restructured in 2016. The whole cost of the project was estimated by business publications to range between US$650 million and US$1 billion. In May 2021 this building, alongside the Chinese and Russian diplomatic facilities in Australia, were the targets of a bomb threat posted on Dutch sports site Sportnieuws.nl that was hacked by persons calling themselves 'Encore Ong' and ‘Zehang T’. Design Overview The Mercury City Tower's distinctive copper-colored cladding makes the building stand out among its neighboring skyscrapers in the MIBC as well as the entirety of Moscow. The building was originally designed to be surfaced in reflective silver glass in order to mirror the buildings surrounding it, but this eventually was replaced by an equally reflective bronze-tinted glass. This gives the building a constant orange glow that makes it appear as it is embracing itself with the sunlight on the horizon. This was according to Egeraat in an interview with Arch.ru introduced by Egeraat's Russian colleagues. A media facade of two million LEDs was installed on the exterior of the 67th and 68th floors of the building, the tallest media facade in Europe. The Mercury City Tower also has a unique setback shape, in which the building steps back twice along its northwestern facade, creating a tapering effect that extends the building's height in conjunction with the vertical skeletal striping that show its corners. Each setback has a slanted roof that supports the illusion of added height. For greater reliability, two independent reinforced concrete skeletons were provided to make the Mercury City Tower resistant against a 6.0 magnitude earthquake. This as a result gives the building a futuristic and high-tech look, fitting it in the Structural Expressionist architectural style. After Williams' death on 25 February 2010, his successor Egeraat stated it would be improper to make significant changes to the tower and focused on improving the upper levels of the building, elaborating a functional solution for the skyscraper, and developing interiors of public spaces. Environmental The building is claimed by architect Frank Williams as the first environmentally friendly building in Russia, since it was designed to collect melting snow water, as well as provide 70% of the workplaces with access to daylight. The building also features a smart “energy cycle” system that regulates energy usage, ambient temperatures, and hot water distribution throughout the development.
