In the totality of the architecture and construction industry we are dealing with just a few percentage points of the exceptional buildings designed by the top-level architects. Even in that miniscule segment we have quite a large number of mediocre architecture and very few architectural jewels. This is not the main area of interest for OAS (although exceptional architecture can be created). The rest of the architectural and construction operations are in the range from nothing to trash. The initial reasons to start working on OAS are connected with the change of that condition.
