Airport Terminal Prestressing
Unbonded prestressing works for the north and south concourses of the T2 terminal. The 255,000 m² terminal uses prestressed floor and beam structures from levels 2 to 4, with approximately 450 t of strand.

Engineering requirements
Tendons extend across floors and beams on levels 2 to 4 of both concourses. Multiple work fronts, congested reinforcement and closure strips require coordinated installation and stressing, including concrete-strength requirements at closure strips.
Project scope
The work included tendon profiling for beams and slabs, coordination with dense reinforcement, anchorage layout, staged installation and stressing across multiple concourse work fronts.
Project application
Unbonded prestressing serves the terminal's long-span and extended floor and beam structures. The project experience covers tendon installation across multiple levels and work fronts, together with stressing arrangements associated with closure strips. Photographs identify tendon positioning and anchorage details requiring construction-stage coordination.
