China, world leader in construction and cancer, is planning to build the tallest edifice on Earth in just 90 days. Pre-fabrication figures into the equation, of course. From CNNGO:

“In an interview with Xinhua, BSB chief executive officer Zhang Yue (张跃) said the company plans to break ground on Sky City in November 2012, and that the tower will be completed in January 2013.

The company is confident the government will green-light the project.

BSB is renowned for its eye-opening construction efficiency. Its portfolio includes assembling a 15-story building in six days in June 2010, and erecting a 30-story hotel in 360 hours in December 2011.

The key to achieving such stunning speed is an innovative construction technique developed by BSB.

Most of the company’s buildings are pieced together with prefabricated components from its factory. In this case, 95 percent of Sky City will be completed before breaking ground.”
