In Turkey (Istanbul), there is a wide range of construction and code enforcement. A very good friend (huge international construction company) and his engineers explained what I was seeing the first time I visited.
On multiple story residential construction, there is a concept referred to as "midnight construction" that commonly occurs on land that has disputed land ownership due to the laws and the amount of transfers and construction starts. Some contractors will start construction very quickly on a 24/7 basis and delay payments to subs and there is no inspection because of the clouded land ownership and not permits or authority since the construction can move faster than the municipal authorities. Ultimately, the situation is resolved because the land value is elevated by the construction. This is a rare local situation relating to 5 to 7 story residential buildings in a city that has a very long history (2000+ years) and numerous property transfers.
There are many great, qualified engineers in the major cities and the projects completed reflect the economic value and amount of construction value in a city of 12,000,000 to 18,000,000 in two continents.
If I were starting a residential project, I would request the owner to give you the name of the city and the specific legal location to verify ownership. In most of the smaller cities and towns, the pace of construction is slower except for some of the developing coastal cities. I attended several meetings of building officials and felt the local engineers were highly qualified. If this is smaller residential project, the risk and complications are minimal.
If you need someone on site, I would volunteer to go back to this gem of a country, education and technology.
