The main Academic contribution of this research was to relate the management of stakeholders with the construction of trust relations. For, as Rose and Schlichter (2013)and Strahornet al. (2015)have, although trust and stakeholder management have many studies because of their importance, few are dealing with interaction and trust. The other contribution is the theoretical relevance and statistical significance of the typology proposed by Hartman (2003)for the trust relationship. There are in theory other trust's typologies (Dervitsiot is, 2003;Mayeret al., 1995), but as presented by Pinto et al. (2009)the Hartman typology is indicated for the project environment and confirmed its relevance in this research for the sample studied.
