#Top-down #construction—constructing floors at ground level, then raising them to the top of the #building and then successively downward—potentially offers an attractive alternative to conventional construction, with its costly, labor-intensive, and environmentally wasteful process of building steel frames, floors, walls, and all components of a building at height. But adoption of an advanced form of top-down construction has not become widespread. With recent refinements, however, top-down construction has become a much more practical option. Under current commercial real estate business conditions—namely, soaring construction costs, labor scarcity, and environmental degradation—the cost savings, labor reduction, and enhanced sustainability of this approach have become even more compelling for the commercial real estate industry.
