Due to local laws, construction workers can only hire local residents. These laws and the lack of local labor and building materials, the use of cast-in-place concrete structure can cause construction costs for domestic building be as much as 6~7 times more expensive; More seriously, the level of expertise of the local labor is low. The construction time of this three-story structure could be as long as 2~3 years, which seriously affects the hotels operation plan.
In order to save the construction cost and shorten the construction period, the construction party decided to adopt the fully assembled concrete frame structure, produce the components in China, and ship them to Tianning Island for assembly, so as to reduce the on-site wet operation as much as possible.
Because Tianning iIsland is close to the Mariana Trench seismic zone, which is equivalent to 8 degrees and a half fortification intensity in China, and the project is located at the seaside with a basic wind speed of 175mph (about 280km/h), the structure must have good mechanical performance and seismic performance.
