30 Storey Hotel (T-30) Construction in 15 Days - Coordination and Collaboration at its Best

A 30 story, 17,000 square meter hotel - T-30 is built in 15 days in Changsha, China. Building foundation was laid ahead of superstructure construction and superstructure was built with prefabricated components. These ultra fast construction schedule was only made possible with the help of prefabrication technologies. Prefabrication is changing the way buildings are constructed.

 

 It will be interesting to look at the level of coordination and collaboration needed for this sort of perfection. Tools like Building Information Modeling (BIM) and Last Planner System (LPS) become even more important for achieving this level of perfection in coordination. Making sure that each component fits on site as intended and functions as designed would be only possible with 3D coordination and 4D schedule visualization. Coordination in fabrication facilities will be efficient with the application of Last Planner System. Moreover, effective supply chain management during construction will be critical. Just-in-time delivery of components will require impeccable coordination between suppliers, manufacturers, warehouses and construction team. Prefabrication method is leaner than on site construction and wide adoption of prefab methods can make it cost effective as well.

Chinese company Board Sustainable Building, who built this hotel, claims that this building is 5 times energy efficient than industry standard and is earth quake resistant for up to 9.0 earthquake. There are skeptics about safety practices applied during construction however company claims that prefabrication helped reducing the safety risks.
