lready the highest in Germany and perhaps in Europe,
Frankfurt’s skyline is adding yet another new building—
quickly. Construction on the “TaunusTurm”—literally
TaunusTower—began in 2011; completion is anticipated by
the end of 2013. The tight schedule, combined with a restricted
delivery zone in the busy financial center, required some inno-
vative approaches to surveying and construction management.
Office Space, Living Space, Public Space—All Green
The construction project consists of the TaunusTurm tower for
commercial office space, an adjoining residential tower and
underground parking for 350 cars. The two new buildings are
set in an existing row of buildings and are harmonious with the
historic buildings in the area. Portions of the lower floors will be
accessible to the public, such as a lunch restaurant on the first
floor, and a pedestrian promenade will be developed at the
front of the building adjacent to a large park.
The office tower will be 170 m (560 ft) high with 40 floors
providing about 60,000 m² (645,000 ft²) of rentable space out
of a gross floor area of approximately 105,000 m² (1,100,000
ft²). The building’s unique shape features six corners, creating
particularly attractive office space for tenants. A double-sided,
symmetrical beveled roof adds to the tower’s striking impres-
sion. In addition, the 70-m-high (230 ft) residential tower will
provide 44 apartments in the highly desirable city center.
Architects Gruber + Kleine-Kraneburg won a design competi-
tion for the TaunusTurm project in 2000. From the start, the
objective was to keep energy consumption and emissions very
low and attain the U.S. LEED (Leadership in Energy and Envi-
ronmental Design) Platinum standard, which is the maximum
level for resource-saving construction and operation.
The TaunusTurm project was initiated as a joint-venture by the
U.S. firm Tishman Speyer and Germany’s Commerz Real AG.
Final details and the decision to begin the high-rise construc-
tion project were made in 2011.
As primary contractor, the global firm Ed. Züblin AG--the market
leader in construction engineering in Germany--oversees all
aspects of the building’s construction. The urban setting and
restricted site access placed severe constraints on construction
activities. With very little room on site, many of the building’s
components needed to be installed immediately upon arrival.
As a result, the site experienced a continuous flow of trucks
carrying concrete and other materials.
The complex logistics and demands for the rapid pace of
construction posed frequent challenges to Gemmer und Leber
GmbH (IGL), a German engineering firm specializing in survey-
ing for civil engineering, pipeline construction, hydrography
and other industries. The project needed complex surveying
suited to all construction requirements. The surveying plan
was developed by Willi Almesberger, IGL’s graduate engineer
and had to account for the unique construction requirements
and rapid construction pace, while also facilitating flexibility in
deploying the surveying teams.
