Building expertise for BTP professionals
Between professionals, we understand each other
Are you an architect, an entrepreneur, a craftsman? You are sometimes confronted with situations where an external technical look is necessary: reception of delicate work, dispute with a customer, disaster on site, complex pathology to analyze, technical arbitration between state bodies...
Calling on an expert colleague means securing your project, protecting your responsibility, and providing impartial technical advice in conflict situations.
The problem? Many professionals are reluctant to call on an expert for fear of being judged or losing face. Error. A good professional knows how to recognize when he needs an outside look.
