CASE STUDYASIA – KINGDOM OF SAUDI ARABIA - WADI HANIFA

#CHALLENGEConstructing a viaduct that crosses the 120 km-long Wadi Hanifa valley in the Nejd region in central Saudi Arabia.

#SOLUTIONDeal has re-designed the superstructure, originally foreseen as a cast-in-place multi-cell box girder, and turned it into a precast segmental single-cell box girder.

Moreover, our technical office has provided substructure design check, construction engineering, shop drawings and, later on, temporary works and precast yard detail design.

Subsequently, we have supplied the specialized equipment and materials for the viaduct construction and we have assisted our client during all the construction phases with qualified personnel on site.

#OUTCOMEThe project has been successfully completed in one year. The time performance is remarkable, especially for erection rates out of the learning curve : one span (77 m long each) per week.
