The success of a project is dependent upon the quality of the preliminary studies.

We have the skills and means in-house to carry out research studies and documentary analyses, to conduct 3D laser-scanning surveys, and to perform test probes.

Having perfected a method based on the centralisation of information, we are able to react rapidly with precise digital models to conduct diagnostics, feasibility studies, and tools to display 3D architectural models.

Our ability to assess risks and anticipate required actions regarding architectural, constructive, and statutory constraints is a genuine asset for our clients.
