i have had extensive dealings with Tameer on Tameer Towers and various other projects of Tameer througout the UAE. When I spoke with Tameer in September 2012 they confirmed that they are waiting for approval from the master developer to allow their new main contractor on site but they did not know when this will happen. This story they have been telling me since January 2012.
Apparently they will start building on Tower A & B and once they are both past 50% they will start on Tower C & D. They offer no money back but are willing to offer discounts and extending the payment terms. This I have rejected because I have lost confidence in them.
I have instructed a solicitor and we are filing for arbitration in Abu Dhabi in the new year. Also, Tameer's office in Abu Dhabi is closed and the client relations director now sits in Princess Tower, Dubai (the handover office).
If I can help, please let me know!
