VVIP Hangar

Client:

PT Pacific Prestressed Indonesia

Project Location:

Jakarta, Indonesia

Project Scope:

Structural design of hangar roof structure, canopy, and wall pockets for sliding hangar doors, post-tensioned tie beamd and construction engineering (erection sequence, shoring and shoring removal)

Project Details:

  • Clear span: 85 meters
  • Length of hangar: 52.4 meters
  • Ceiling height at crown: 23 meters

Challenge:

To minimize in-place casting work and amount of material (concrete and rebar), and reduce construction time.

Solution:

Structural design features precast arch segments  using open folded plates 

Results:

From past experience 55% savings in concrete and 40% savings in rebar are achieved using the precast  folded plate roof system in comparison with conventional  design using cast‐in‐situ concrete.  Fabrication and   erection of the entire precast roof arch segments took  only 4 months.

Total Construction Cost:

US $8 million (completed in 2009)
