The Kuningan Flyover in Jakarta:
Cantilever Erection for efficient Construction Progress
The Kuningan Intersection in Jakarta, Indonesia is an important traffic hub that connects different business districts
with several embassies and the airport. For many years, considerable traffic jams have occurred at this junction.
An attempt to solve the problem by building a conventional cast in place viaduct on the north side of the intersection
in 2002 was unsuccessful.
Thanks to the new, 680m long and 9m wide
Kuningan Flyover on the south side that was
opened in December 2015, the situation
has finally improved. The flyover was built
using precast concrete segments and the
balanced cantilever construction method.
The General Contractor decided to use two
different construction methods in order to
reach the target schedule and to minimize
traffic interuption during construction.
The precast segmental concrete box girder
for the 6 approach spans was erected using
lifter frames, and the 160m long main span
was built using the balanced cantilever
method and DYWIDAG Form Travelers.
PT Delta Systech Indonesia was awarded the
contracts for post-tensioning work, segment
erection and engineering services. In a joint
venture with Utracon Structural System Pte
Ltd., Singapore, PT Delta Systech used 2 sets
of static standard lifter frames for mounting
the precast segments for the hollow box
girder using the balanced cantilever method.

In cooperation with DYWITECH Taiwan,
PT Delta Systech Indonesia also used 4
DYWIDAG Form Travelers for the cast in
place balanced cantilever part of the bridge.
A total of 78t of Types 15-0.6" and 19-0.6"
DYWIDAG Strand Tendons were needed for
post-tensioning the precast concrete elements
and the cast in place balanced cantilever
bridge spans. PT Delta Systech supplied and
installed the post-tensioning systems including
Types MA 6815 and MA 6819 Anchorages.
Furthermore, DYWIDAG Bar Tendons were
used for temporary stressing in order to
stabilize the segments during erection work
and form traveler operation.
