the millimetre-precise cone milling, which<br />
shortened the machining process by a factor<br />
of 10 compared to conventional routers.<br />
Prof Dr Christina Jeschke from Biberach<br />
University of Applied Sciences explained what<br />
the buildings of the future might look like from<br />
the outside, whether with wood, cork, plaster,<br />
fibre cement, metal or glass.<br />
Twenty storeys are distributed over a height of<br />
72m. The completion of Roots in Hamburg’s<br />
Hafen City is planned for 2024 and will serve<br />
as “a flagship project for modern timber<br />
construction in the future”, according to Leitz.<br />
<strong>WIA</strong><br />
More than 120 guests turned up for the symposium<br />
Using various examples, the professor<br />
presented everything that was possible in<br />
facade design in modern timber construction<br />
and which materials could be used.<br />
For her, a change in thinking is already<br />
necessary in the training of young architects<br />
and designers so that sustainability aspects<br />
such as a circularly effective materials<br />
management are directly considered.<br />
However, she also pointed out that the<br />
weathering of wood could be a challenge in<br />
construction, and therefore it must be planned<br />
for that the wood would change visually over<br />
time.<br />
Luciano Tagliaferri from the Italian machine<br />
manufacturer SCM and Andreas Kisselbach,<br />
head of the R&D department at Leitz and<br />
moderator of the symposium, then introduced<br />
the technical basics of modern timber<br />
construction.<br />
The aim is to eliminate the need for reworking<br />
the individual building elements on the<br />
construction sites. This is made possible, for<br />
example, by modern machine concepts for<br />
six-sided machining of the components and<br />
building elements.<br />
There is now much more to sawing, cutting and<br />
drilling in timber construction than there was a<br />
few years ago. For example, it is about complex<br />
five-axis machining, high-precision drilling in a<br />
short time and modern cutting strategies.<br />
At the end of the symposium, Oliver Fried<br />
from Rubner Holzbau presented on what is<br />
Germany’s tallest wooden high-rise building<br />
as of September <strong>2023</strong>, Roots, though it is still<br />
under construction.<br />
