For structural works that call for it, we work closely with technicians, architects and engineers, so as not to get in each other's way or do the same job twice, thus avoiding an increase in costs.
Works coordination is done onsite as well as at the workshops of the different tradesmen involved. If the project is structural, coordination is done together with the technicians involved.
In terms of handling quotes, our policy is to make contact—depending on what our client wants—and inform the potential vendor of the materials required. Once we've done this, our job ends as it will be the client who will have the final say. It will be up to both parties to close the deal. Our firm has nothing to do with the business negotiations.
