Detailed notes

## Background Published by the YouTube channel AI+R in January 2012, this video presents a time-lapse record of the construction of a 30-story hotel prototype, J57, in Changsha, China. The description details how Broad Sustainable Building (BSB), a subsidiary of Broad Group, assembled the prefabricated modular skyscraper in only 360 hours to demonstrate the precision, energy efficiency, and reduced waste of modular engineering.

## TL;DR The presentation showcases the rapid 15-day erection of a 30-story modular building completed just before New Year's Eve 2012. Factory-manufactured components are brought to the site and assembled at extraordinary speed to highlight Broad Sustainable Building's construction methodology. In place of conventional technical narration or explanatory dialogue, the audio track merely features consecutive, repeated acknowledgments of “Thank you.”

## Atmosphere & style The presentation carries a sterile, highly focused, and utilitarian mood, prioritizing visual demonstration over conventional narration. Stripped of spoken technical commentary, the repetitive audio murmurs of gratitude lend an ambient, almost surreal formality to the viewing experience. The overall tone feels brisk and industrial, leaving the rapid assembly of the structure to serve as its own understated spectacle.

## Bulletin - Chinese sustainable construction firm Broad Group constructed a 30-story hotel prototype, J57 in Changsha, in 360 hours (15 days), following a prior project that completed a 15-story building in one week. - Broad Sustainable Building (BSB) structures feature high-precision prefabrication (+/- 0.2mm), magnitude-9 earthquake resistance, 5x energy efficiency, 20x purer air, and generate only 1% construction waste. - BSB planned a rapid scale-up from 900 employees in 2011 to 19,000 employees and 360,000 square meters of workshops by 2013, targeting an annual production and installation capacity of 10 million square meters. - By December 2011, BSB technology was finalized across 12 completed buildings spanning Changsha, Xiangyin, Shanghai, Zhejiang, and Mexico, alongside franchise expansions in Ningxia and Fujian.

## Video description What can you accomplish in 360 hours?

The Chinese sustainable building company, Broad Group, has yet attempted another impossible feat, building a 30-story tall hotel prototype in 360 hours, after building a 15-story building in a week earlier in 2011.

You may ask why in a hurry, and is it safe? The statistics in the video can put you in good faith. Prefabricated modular buildings has many advantages over conventional buildings.

Higher precision in fabrication (+/- 0.2mm). More coordinated on-site construction management. Shorter construction time span. Lower construction waste. Also many other health and energy features are included in Broad Sustainable Buildings (BSB)

The building was built over last Christmas time and finished before New Years Eve of 2012.

BROAD SUSTAINABLE BUILDING CO., LTD

Established in March, 2009, BROAD SUSTAINABLE BUILDING CO., LTD is a wholly-owned subsidiary of BROAD Group, solely operates the magnitude-9 earthquake resistant, 5x more energy efficient, 20x purer air, 90% factory-built, and 1% construction waste Broad Sustainable Buildings (BSB). BSB headquarter and its R&D Center are situated in the Xiangyin County of Hunan Province in Southern China, with 80,000sqm workshops, 900 employees in 2011. In 2012 with 220,000sqm workshops, 12,000 employees, and in 2013 with 360,000sqm workshops and 19,000 employees, reaching an annual production and installation capacity of 10 million sqms. BSB's central goal is:

1. Improving R&D of BSB technologies, setting up supply chains 2. Sell BSBs in compliance with local regulations in the Hunan building market. 3. Transfer BSB technology to 100 partnership enterprise, every Chinese province and distributed evenly in each nation worldwide.

By December, 2011, BSB technology reached finalization, altogether with 12 BSBs built in Changsha, Xiangyin, Shanghai, Zhejiang and Mexico and developed 2 franchise partners in Ningxia and Fujian with identical factory sizes to the Xiangyin BSB Factory. Another 10 Chinese & international potential partners are in negotiation.

BROAD envisions in the near future, there will be one BSB among three buildings worldwide, allowing all men and women to share BSB's solace.
