Scope of our work
conceptual design, construction design, fabrication and construction supervision
The bridge is the result of an incredibly ardous, but rewarding, planning and construction process that continued for over 20 years. Back then, with a span of 457 metres, it was the largest cable-stayed bridge in Asia, designed and constructed in such a way that indigenous construction companies were able to build it relying exclusively on local labor materials. In order to enable the section-by-section assembly of the grid during cantilever erection using simple riveted joints, a simple plain steel grid with composite concrete slab was developed. The grid consists of simple open I-beams, two longitudinal beams at the edges suspended directly from cables and a load-distributing central longitudinal beam, as well as cross-girders at intervals of 4.1 m. The grid serves as the “permanet falsework” and stiffening for the subsequently manufactured 35-m-wide in-situ concrete slab that cantilevers at both sides.
