Their estimated cost 770million for 4.5 million sqft = 171 US$ per sq foot. seems to be at international rates.
If you compare Dubai Silicon Oasis , with very high cost of construction employing foreign labour, their approx. cost was below 150 US$ and selling price of sq ft was 177 US$ in early 2014.
It is true the prices have escalated but considering our working environment and availability of local sub contractors I think they may get some jobs done below estimated amounts after doing some changes, specially by deleting unwanted and unmatched high cost interior and exterior ideas of money wasting architects.
