At the site, the prefabricated modules can be assembled very quickly, like giant Legos.
This approach is rare in the United States, where most building are stick build from raw construction materials on site, except for some sophisticated ceiling trusses. A notable exception in Denver's recent building boom was a new apartment building that went up next to the University of Denver light rail station. It has also been proposed for a nuclear power plant construction plan (from 2005).
But, a project in China, the construction of a 57 story building with 800 apartments and offices for 4,000 workers from 2,700 modules assembled in just three weeks on site (after many months of assembling the modules in the construction company's factory), dramatically illustrates the true revolutionary potential of this approach to construction. The last 37 stories went up from January 31 to February 17 of 2015.
According to Juliet Jiang, a senior vice president of Broad Sustainable Building, that built the project:
"One hundred percent (of the) parts are factory-made. We don't waste any materials, no one is idle in the workshop or on site. We have very good planning."In contrast, it took almost five years to build London's 37-story Walkie Talkie building which opened in August 2014.
Jiang said that the processes employed by the firm are also far more cost effective, environmentally friendly and lead to less disruption in cities during construction.
