Hey Shyams,by the way, my husband is in construction and had the pleasure of visiting the site office.He was most impressed with how high the quality of the work is and the finishing of even the manholes are of very high standards.There is nothing wrong with precast housing! It's certainly better then some of the houses that I have seen being built here in Qatar.Bilfinger Berger are the constructors and they are German,so that says it all.We applaud Barwa and Bilfinger on the fantastic job they are doing for the government.
