Harmonizing structure, culture and engineering.
The whole Industrial Ring Road is a 13 kilometre long project consisting of a motorway and two bridges crossing the Chao Phraya River twice.
These two cable stayed bridges have navigation spans of 398 and 326 metres. The project also includes three approach structures, including a 50-metre central peninsula interchange that connects the west approach to the main north-south motorway.
Geometry, coordination and a dense urban setting
The structure imposed tight geometrical constraints on both the cable-stayed back spans and the interchange itself. The architecture (by Mott MacDonald in collaboration with Yee Associates for the feasibility study) reflects Thai culture, forming the diamond-shaped configuration concrete pylons inspired by the pointed ceremonial hats of Thai dancers and temple roves.
The conjunction of these major challenges of building a megastructure called for careful consideration and implementation. Egis was commissioned to carry out detailed design and works supervision given our long-standing experience in major segmental bridge structures and geotechnical works in heavily congested urban settings.
From a project management point of view, implementation was successful also due to Egis’s proficiency in managing the interfaces of different stages of megaprojects and types of infrastructure. We proved our ability to harmonise various sorts of design and implementation codes and products for delivery.
