Modular Construction that Leads the Way in China; Can Lead the Way in the US too


Yueyang, a Hunan province in China is home to the recently opened 30-story Tower Hall—the country’s first high-rise building that was pre-constructed inside a factory a short drive away. The newest construction method is gaining acclaim in China because many of the country’s buildings are designed according to 19th century standards and are notoriously energy inefficient.  In addition, the country has a growing urban population, and housing around the country is at a premium.  The same modular construction technology is also a viable choice in the United States and the rest of the world.

China has long been plagued by housing problems because of overpopulation, and the issues are extremely acute in the country’s urban sectors.  The Chinese construction industry is known by dubious practices that cause many structures to fail because of large quantities of waste and being environmentally inefficient. In addition, there is a large amount of waste and environmental pollution that is associated with traditional construction projects.  Modular construction is being touted as a cost-effective alternative that is ideal for China and the rest of the world.  Modular buildings are mostly manufactured on a factory floor reducing product waste and its impact on the environment.  The various walls and panels are pre-wired and assembled inside the factory, drastically reducing labor time and expense.

The benefits of modular buildings are growing by leaps and bounds, and the newest project in China offers a number of benefits to the construction industry.  Tower Hall was erected in a mere 15 days and produced about 1 percent of the waste of a similar site-built residential tower.  Because most of the structure and modules were assembled in the factory and fastened together on site, the project was completed in minimal time with fewer labor expenses. Factory construction also reduces the chance of weather delay and material damage leading to earlier occupancy. Material expenses were also lower because Tower Hall used about 10 percent of the concrete that traditionally constructed buildings require.

The building is remarkably energy efficient and has 35-centimeters of insulation panel along the exterior walls.  The panels ensure efficient cooling during the sweltering heat of Hunan summers.  In addition, Tower Hall is designed to withstand 9.0 earthquakes on the Richter scale.  Investors are now being sought out to help with funding a modular tower that will be the world’s largest building.  The newest project is for a 200-story high rise that would come to completion in a mere 60 days.

Modular building technology is bringing promise to China because it can be extremely energy efficient and requires fewer on-site labor hours than traditional techniques.  The same technology is ideal for the United States where new innovative ways in which to live are increasingly being pursued.
