  How should computer science and social science collaborate to build a common
model? How should they proceed to gather data that is really useful to the
modelling? How can they design a survey that is tailored to the target model?
This paper aims to answer those crucial questions in the framework of a
multidisciplinary research project. This research addresses the issue of
co-constructing a model when several disciplines are involved, and is applied
to modelling human behaviour immediately after an earthquake. The main
contribution of the work is to propose a tool dedicated to multidisciplinary
dialogue. It also proposes a reflexive analysis of the enriching intellectual
process carried out by the different disciplines involved. Finally, from
working with an anthropologist, a complementary view of the multidisciplinary
process is given.
