It is commonly agreed that AEC (aka: construction) at present produces over 30% materials waste from each residential project. 1.4 trillion in waste is produced annually in construction. Consider that rejected or discarded material also wastes associated labour of producing and discarding it. These are large disadvantages to common construction both in cost, time, and our natural environment. AC uses materials and energy efficiently to eliminate a great majority of this waste. This alleviates pressure on landfills with their associated greenhouse gas production. Further time and energy is saved with automated contracts, rapid, efficient transactions, precise logistics tracking and inventory. IOT assists by eliminating losses due to logistical/transport mistakes, accidents and theft. Augmented Reality saves travel time, reducing traffic and wasted fuel, while also preventing mistakes and change orders. Project execution is accelerated through the User Interface, remote site planning and operations.
