It is without question Cologne site with the best views: the Max Cologne on the Deutz Rhine. Reason enough to put on the hard hat and watch the work on the former headquarters of Lufthansa near: contribute to the lay the mountains of broken concrete pieces, twisted iron reinforcing bars and broken facade elements as a single opaque chaos. The part demolition, building up to the foot of the bleak looking building, which once again the proud headquarters of Deutsche Lufthansa AG formed.
falling from the sky on the dusty Ground.
Those days are long gone. At every corner of the building site workers make a large and small device because parts of the building, the annex and the intervening located parking decks to break apart and. A system can not recognize at first glance, the logistical effort and the immense planning of construction processes can only be guessed at.
The plans of the architects of HPP Hentrich-Petschnigg & Partner provide that the massive structure of the building of the tower is broken. For this, the facade is cut in several places. This also ensures a better exposure in the interior. The stair cores, which rose up in the existing high-rise as a gray-brown concrete columns, the facade will disappear behind extensions. This means that even should the eastern - the Rhine Averted - buildings connection to get a viewing dome. In the fall of 2012, the plan should the tower and the annex, the so-called Rhine floors, be ready. A total of 46,000 square meters of office space created.

The location right on the Deutz bridge vis-à-vis the old town in the truest sense of the word is not reproducible and the existing building is a real challenge. The existing buildings are immense depths of 25 to 30 meters by today's standards. Attractive offices can not accommodate in the dark depths of space. "We therefore take this sort dark areas, where the technology separately on each floor of a decentralized," says Mueller, adding: "As a result, we gain in return, the former technical floors than land.

in the walls and ceiling of the existing buildings can be found just about any material that is in the construction of the building in 1969 and the Rhine floors in 1978 but very modern, but now often more suitable for special disposal. "We still can reuse much of the concrete and steel elements of buildings," said Mueller. This recycling has also contributed to the Max, the Cologne- DGNB has received preliminary Gold, like the fact that there is no additional land use. "We can even use the existing well system and equipped with modern technology," he says. Thus, the property will require no external power other than energy.

Not that the former would Lufthansa Tower been by today's standards in the original state of beauty. "Striking" was probably still the nicest description of the monumental and quite disproportionate colossus on the Deutz Rhine. By 2007, the administration had resided here the largest German airline, together with their directors. In the basement there was even an in-house printing, were printed in the ticket.

On the construction site that day not only workers on the move. "We currently have the archaeologists on site," explains Rolf Müller, branch manager of Hochtief Project Development , and points to an excavated pit, coated up to the March nor the three above-ground parking levels above the other. The parking deck had the tower and the Rhine as a giant concrete floors carpet enclosed and the massive group impression reinforced. Crouching in the pit two archaeologists. In her careful, incisive approach does its work almost like a caricature of the brute force of the giant cranes, excavators and demolition devices that erode around them on the skeleton of the skyscraper. Among other things, the largest Longfrontbagger Germany at the construction site is in operation. In Cologne, a little construction project without the participation of archaeologists - to tackle the Romans, thank. That's when Max Cologne otherwise, especially as stand between the existing buildings and the adjoining Greek Orthodox Church of St. Heribert the remains of the east gate of the Roman fort.
