This research project was initiated in the end of December 2012 to support the main project proposal entry for Terminal 3 Soekarno Hatta Airport Extension under the lead designer and engineering architect office: PT Biro Insinyur Exacta. Formologix Lab had a rare opportunity became one of the collaborators among other expert teams – such as PT Hutama Karya (contractor), Nyoman Nuarta (indonesian based world artist), Studio Padi (architect office), etc.- which took part in developing a skin design for the entire extension airport building.

Garuda – as proposed by Nyoman Nuarta – was the basic notion that interpreted to represent the underlying message of national unity and a symbol of celebration of Indonesia’s cultural diversity. And The Flaps Sequence of Garuda’s Wing had been decided as the expression which articulated into the form of the building.

Interpreting the flap of wing

The expression of “the flap” literally implemented to the main airport building skin. A skin that not only perform as functional architectural elements only, but potentially perform as ornamental pattern that could evoke dynamic experience and emotion to the building occupants. In order to convey those performances, non uniform basic surface (NURBS surface) was borrowed and developed the skin cover, supporting structure and member in parametric system.

defining the basic geometry for the building envelope to be developed as the building skin in parametric system

Through parametric associative modeling tool we used -Rhino+Grasshopper-, we borrowed the basic-form’s properties -vertices, iso curve, faces, etc.-  as inputs in determining the mass customization of structural member, roof panel, skylight module and other architectural elements.

Sequential development of building skin elements

Most of three major alternatives of building skin which developed from three basic surface -planar, single curvature surface and nurbs surface- were implemented in the design. The skin developed from nurbs surface was implemented in the main airport building, the skin developed from single curvature surface and planar surface were implemented in the main conveyor corridor and supporting facility buildings.

During the completion of the research project, the circumstances gave us great experience about the advantages of utilizing parametric associative modeling: it allowed us to connect and relate the selected constraints and variables of skin design formula to achieve numbers of variation at anytime that was so useful for discussion among members of the team to visualize them when some alternation occurs.

As the end of the project tender, Angkasa Pura 2 finally selected Woodhead as the proposal winner. Woodhead was commissioned to to be the lead designer of architecture and interiors for the new Terminal 3 extension that should be completed by the end of 2015.
