Dubai question? on Construction in dubai in the 70's and 80's

guys how was the construction in dubai in the 70's and 80's, i know most of the skyscrapers and buildings have come up in the last ten years, but i remember 20-25 years ago dubai was still a hot construction zone, i mean people use to go to dubai for construction jobs like crazy, my question is what major construction projects took place during the 70's and 80's. and ya how big was dubai 15-20 years ago, what was the down town back then
