Ibs score for project (group of buildings)
Project information: - Main buildings in the development consist of 5 blocks of buildings.
The IBS score for each building are:- i) Block A - 5 storey apartment
Construction area, QST (building)A = 3,000 m2 IBS Score(building A) = 83
ii) Block B - 5 storey apartmentConstruction area, QST (building)B = 3,000 m2 IBS Score(building B) = 87
