Start analyzing and writing

early on

Course-correct where

needed

Automate processes

o E.g. data processing in Matlab

Setting up own research lines:o Existing Bridges

o Difficulties: • contact with Ministry of

Transportation?

• Information is missing

• No awareness

• Laboratory and tools: limited

• No “research group”

o Solution:• Desk research

• Presentations to raise awarenessabout existing structures

• Service: international committees
