Nanning Wuxu International Airport located in the Guanzi region of China is designed with a grand main arrival hall and four terminals branching out from the central space. The profile of the fluid form mimics that of a bird in flight. The main hall contains a diagrid ceiling which acts as a skylight allowing ample natural light to fill the space. The organic form is held by several “Y” shaped supports acting as the internal bone elements in a wing. The entire project is parametrically modeled to maintain continuity of the smooth form. Traditional architectural drawing documentation is not sufficient to explain the complexities of the project. Several sections are cut through the form at critical locations along the site. At each section, important working points are called out. A custom algorithm is used to automate the documentation procedure for setting out and naming the project work points, which minimize production time.
