5D BIM (Building Information Modeling) however, is turning out to be critical in closing this gap. 5D BIM involves extraction of construction information from intelligent BIM ready virtual building models.
In the midst of Australia's housing affordability issue, prefabricated homes offer a solution. Experts believe that prefab housing is likely to decrease the cost of a new habitant by at least 10 per cent (excluding the purchase cost of land). Case studies of UK show savings of up to 10% to 15% in building costs and a 40% reduction in construction timelines. Manufacturing is more efficient, and factories don't lose time due to bad weather.
