Aerial view of Haitian Center, the tallest building in Qingdao. Haitian Center consists of T 1, T2 and T3.

Building 2, the tallest building in Qingdao, with a design height of 369 meters, has also officially gone to the sky.

Using laser positioning, three-dimensional technology and computer software to optimize the radian of steel column, the angle can be changed four times on a steel column with a length of 10 meter, but this change is imperceptible to the naked eye. "

The design of Haitian Center takes into account two elements: "the memory of the city" and "the rhyme of the sea". As the basic plane shape of the tower, the rhythmic curve originates from the local vertical direction, most of the indoor space is regular, and the overall facade emphasizes horizontal lines, which echoes the original Haitian Hotel. The design elements of "the rhyme of the sea" are reflected in the "waves" on the north and south facades, which are generated with the change of height.
