How to innovate Switzerland's built infrastructure?

Experts Peter Matt, Fritz Hunkeler, Hans Rudolf Ganz, Laurent Vulliet and Peter Richner outline the challenges of the Swiss built environment

Buildings, roads, railways, supply and disposal networks, and much more: Switzerland's entire built environment is as complex as its future challenges, due to climate change, natural hazards, population growth and of other factors.
Where to start? With what priorities? A group of experts has launched an initiative for an overview, thus giving new impetus to research and practice.

How to decline the new watchwords in a complex system?

Reduce emissions of CO2 due to heating of buildings, building more densely, using solar energy more and storing it efficiently, rethinking mobility and transport: these are the buzzwords that come to mind of many contemporaries when talking about urgent tasks.
But what is really more important? How to most efficiently use our limited resources to achieve the goal of zero greenhouse gas emissions by 2050, for example?
And how is all this possible when, at the same time, the Swiss rail network is at its capacity limit, the road infrastructure is highly congested and the volume of traffic continues to grow?

These are questions that make even the most prepared observers think. Faced with multiple challenges, five experts now want to give the project new impetus "Entwicklung Bauwerk Schweiz"which started about ten years ago.
Under the guidance of Peter Matt, Fritz Hunkeler, Hans Rudolf Ganz, Laurent Vulliet, professor atEPFL, And vice-president ofEMPA, Peter Richner, the working group wants to provide new food for thought, with a bird's eye view of all the tasks awaiting the Swiss country.
Only such a synopsis makes it possible to prioritize the really important measures on many topics and, in short, to do the right thing at the right time: the five experts are convinced of this.

Five focal points represented in an evocative graphic matrix

Details of the expert analyzes can be found in a new roadmap entitled "The Swiss building stock is under pressure to adapt!".
According to this logic, five segments are particularly affected by the upcoming challenges: the building stock, the freight transport infrastructure, the passenger transport infrastructure, both individual and public, the drinking water networks and the waste water networks.
The roadmap represents, also graphically, the contexts in which its authors see the greatest potential.
In a matrix, the need for action and the potential impact for individual measures are rated as particularly high in thearea of ​​passenger transport and buildings.
Furthermore, mind maps provide an overview: graphs that contrast drivers, i.e. challenges, with possible levers for individual segments of the infrastructure built in Switzerland.
For freight transport, for example, you might find keywords like drones, “Cargo Sous Terrain” and real costs as a basis for the mobility pricing.

A roadmap to expand knowledge and make it usable

More specifically, the experts propose three initiatives: more research to expand existing knowledge; second, ongoing training to ensure it reaches industry professionals quickly; and thirdly, an impulse program to make useful information available to all interested parties in the form of documentation and other tools.
“With the roadmap we are pursuing several objectives”Says Peter Richner, vice president of the Swiss Federal Laboratory for Materials Science and Technology.
"We demonstrate the importance of the infrastructure built in Switzerland for our society, specify the need for action and, above all, raise awareness in society that we can only develop a goal-oriented strategy for the future from a higher perspective."
Detailed information on the five experts' ideas is available on a new website.
In addition to the roadmap, the documents also include "Main themes – Attempt at an overview”, written by Fritz Hunkeler: it is a large collection of materials which should also serve as a stimulus for discussion.
The technical background is illuminated by various symposium presentations”Entwicklung Bauwerk Schweiz" to Bern in June 2013, on which the project is partially based.

Start in 2010 with the project “Entwicklung Bauwerk Schweiz”

The project "Entwicklung Bauwerk Schweiz” was launched in 2010, when an ad hoc working group formulated a project idea that met with great acceptance in the Swiss construction industry.
In June 2013 took place at Bern the conference "Zukunft Bauwerk Schweiz – Herausforderungen, Strategien und Massnahmen” (“The future of the infrastructure built in Switzerland – Challenges, strategies and measures” in Italian), also supported by the Federal Council.
The goal: a comprehensive strategy for the medium- and long-term development of the built environment in view of the challenges up to 2050 and beyond.
The initiative resulted in a first roadmap and was taken forward by the Swiss Society of Engineers and Architects (SIA) with the title "Switzerland 2050“, but all with a slightly different focus on spatial planning and landscape protection.
Since the publication of the first roadmap in 2014, the challenges that theSwiss built infrastructure faces have significantly intensified and accelerated.
