Situated at the convergence of Baihua Fourth and Fifth Roads in the southeastern quadrant of Futian District, Shenzhen, the Baishaling Emergency Repair and Service Center encompasses an area of 4,714.74 square meters. This center features a cutting-edge, superimposed box-steel frame structure that sets it apart. The ground floor is supported by a sturdy steel frame, while the upper floors from the second to the fifth are constructed using modular box techniques, with an astounding 90% of the assembly completed off-site. This pioneering, steel modular construction method significantly reduces on-site construction time by almost 33% and almost halves the amount of construction waste produced, outperforming traditional building practices.
