Q#4 Building Information Modeling (BIM) is the software that generates and manages building data during its lifecycle. It typically uses real-time, three-dimensional, dynamic building modeling software to increase productivity in building design and construction. Advantages of BIM • Unique BIM data entry software avoids the risks of variation and errors linked to the repeated entry of identical data on several media. • Its design efficiency reduces design costs and preparation of contract documents. • Its information is uniform and shared with everyone.
