IPO Meeting Zürich 14 November 2014

Replacing S235 by S355

1. Start 2015: S355 is economic, sustainable and available.

I. Common pool of arguments, examples for economy and sustainability, design tools

II. Coordiantion with producers and stockholders about availability and additional

costs

III. Press informations, technical papers, webpages, newsletters by all IPOs,

producers, stockholders, fabricators etc.

2. Further Development.

Design tools, cost estimation, information for fabricators etc.

Repeat 1. and 2 with improved arguments and tool.

Ideas for next steps

At mid term S235 shall be replaced by S355 and higher grades.

Strategie for the comming years

- What are our arguments for whom

- What do we need to develop or improve

- Who needs to be involved
