Look, this is not the Marmary tunnel whereby you can open the tunnel on time in record time but not have an actual commuter rail system in place that goes most places for another 6 years. It is not the third bridge which opened "on time" a year and a half ago, yet none of the Northern Marmara highway is open, and will not be for at least 3 years, 4 years past its opening date, which means that it is all but useless until then for its stated purpose which was to alleviate transit truck traffic through Istanbul - not to mention that it is key to transport to and from the new airport!. You see I remember when the current IST was built (meaning the international terminal, as the domestic terminal is what the whole airport was less than 20 years ago), and although it was several levels of magnitude larger than what was there before, all of the basic infrastructure was in place. I remember two years into the terminal being open there being large bins everywhere throughout the airport to catch rain from the hundreds of leaks in the roof. I remember never being able to speak with people at the ticket counters because there were no holes in the 4 cm thick glass (and TAV even trying to get 2000 Euros a piece to put speaking holes in). I remember them having to re-tile the floors of the entire departure area, because they had used inferior consumer grade tiles. The luggage system almost breaking down monthly the first six months, or even the fact that there are weight and load issues down below to this day. Hell, I even remember the weird Cargo and logistics island in the middle of the taxiway that at times even had plastic outdoor chairs for the employees that only got paved over a couple of years ago. I can go on about problems and delays to the parking structure, the huge traffic jams for the under planned access roads, etc.
Now TAV knew about many of these things the day the terminal opened. Why then did they open so quickly? Well...........because of political promises and of course the fact that their BOT deal was very strict and they wanted to start bringing in revenue. So a parallel with Limak here? The thing is this: When they opened the new Terminal at the very end of the 90's IST was a second rate airport, it had 12 gates, and TK flew maybe 8 million passengers a year, the whole airport maybe got 10 million a year. As we know now, the World has changed, TK is hitting 70 million a year and has an international reputation to keep as does IST. I can guarantee you that if there is a leaking problem, it will be spoken about everywhere. If the only real road in and out to Istanbul is using the already "upgraded" and over used Gokturk road, that leads to a similarly backed up TEM, then you are going to get a lot of complaints, especially as the Metro will not be open and usable for at least two years past the date.
