In a contract that fills a hundred file folders, property development and investment company Art-Invest Real Estate has commissioned Ed. Züblin AG as main contractor to realise the project Alter Wall Hamburg. Alter Wall Hamburg is an approximately 150 m long shopping boulevard with 18,000 m2 of offices and 12,000 m2 of retail space designed by the renowned architectural firm Gerkan, Marg & Partners (gmp). ZÜBLIN´s business units Turnkey Construction Hamburg/Schleswig-Holstein and Structural Engineering Nord will handle construction as well as the mechanical and electrical installations, with building construction set to begin in the spring of 2016. The full range of construction works, with a contract value of about € 80 million, is scheduled to be completed in the summer of 2018.

Art-Invest is investing a total of around € 250 million in the site, which had already been a vibrant shopping street around 1900, to create another attractive central location that includes an approx. 150 m long shopping boulevard, a pedestrian bridge over Alsterfleet canal, exclusive office space, and an underground car park with a capacity for 220 vehicles. The overall concept also comprises the integration of the nearby Bucerius Kunst Forum (around 200,000 visitors a year), which will move into the centre of the complex and grow from 2,500 m² to 3,400 m² on four storeys to help breathe life into the project’s theme of “Tradition, Art and Quality”.

The new building will be housed behind historical façades on 13 levels: four for the underground car park, three for restaurants and shops, and six for offices. The Bucerius Passage planned for the middle of the building ensemble will lead over a new pedestrian bridge to Neuer Wall.

Securing the historically listed façade
The construction works to be carried out by ZÜBLIN in the central part of the city are quite challenging technically: the new bridge over the canal will need to be floated into place; the ramp to the underground car park will be built in an open construction pit 7 m deep; and to preserve the historically listed façade, it will be secured at every storey during building construction. Alter Wall will also feature many architectural highlights: an 80 m long glass roof will top the building over an atrium in the interior; and the canal-facing façades on the outside of the building will be clad with natural stone to lend them a similar look to the historically listed portions of the building.

LEED certification (Leadership in Energy and Environmental Design) is being sought for the building. The Alter Wall project is an important part of the Hamburg Business Improvement District (BID) Nikolaiquartier. The aim of the BID is to make the locations around Hamburg City Hall and the Chamber of Commerce more attractive.
