From Hönggerberg to WolkenWerk
Since summer of 2017, Lüchinger+Meyer has been realizing the WolkenWerk in the north of Zurich in collaboration with Staufer & Hasler Architekten and von Ballmos Partner Architekten. Meanwhile, the three residential towers Werk B, C, D are built up and the structural work of the first construction phase is near completion.
We gladly agreed on request from the ETH Zurich to present the project on site to students attending the Reinforced Concrete I lecture teached by Prof. Dr. Walter Kaufmann. About 80 young engineers arrived at the impressive construction site on the 24th of October.
Andreas Gianoli, who was acting as project leader, begun with some preliminary remarks. Followed by a presentation in particular about the technically interesting aspects, Blaženka Matošević and Christoph Pfammatter, who were instrumental in the realization of the project, addressed their words to the audience. The focus was mainly on intercepting structures such as the pre-stressed wall panels on the first floor or the pre-stressed beams in the basement as well as the element construction from prefabricated concrete elements.
The primary load-bearing system of the pergolas in the base area consists of concrete elements, which have been modelled as a beam structure. At the same time, they demonstrated “little basics” of structural design of reinforced concrete elements. Using the products provided, the use and function of e.g. punching shear reinforcement, screw reinforcement or shear reinforcement were demonstrated in a practical manner – hands on engineering.
The highlight of the event was a tour of the building shell from the basement to the top floors, accompanied by stories on special challenges of the construction work.
We are pleased that our presentation has sustainably promoted the interest of students in the versatile profession of civil engineering.
