Mega Smart City Civil Substructure Development
Situated 159 km north of Jeddah along the Red Sea coastline, King Abdullah Economic City (KAEC) is one of the Middle East's premier sovereign mega-developments. GY & Sons Holding, in strategic engineering joint venture with international civil consortia, executed the comprehensive turn-key engineering, excavation, substructure piping, transformer installation, and utility commissioning for primary urban sectors of the city.
The scope encompasses 8 complete underground utility infrastructure networks, enabling smart city residential districts, commercial financial zones, and coastal tourist boulevards with uninterrupted power, water, drainage, and high-speed fiber communications.
