en.Wedoany.com Reported - China Harbour Engineering Company (CHEC) completed the hoisting of prefabricated components for all 1,894 villas in Phase 3 of the Sedra Project in Riyadh, Saudi Arabia, on June 11, 2026, achieving a successful topping-out. The project took 1,080 days and involved the hoisting of approximately 208,000 prefabricated components. The Sedra Project is a key initiative under Saudi Arabia's "Vision 2030" framework and represents the largest single overseas housing construction project undertaken by China Communications Construction Company (CCCC) to date.
Founded in 1980 and headquartered in Beijing, China Harbour Engineering Company is a leading international engineering contractor in China, with operations spanning port, highway, bridge, and housing construction, as well as other infrastructure development fields. It has branches in over 90 countries and regions worldwide. Located on the outskirts of Riyadh, the Saudi capital, the Sedra Project is a major component of the Saudi government's large-scale new city development plan aimed at alleviating housing pressure and promoting economic diversification. The project includes thousands of villas across 53 different floor plans, constructed simultaneously in three zones.
According to the project team, the early stages faced multiple challenges, including insufficient production capacity and significant construction bottlenecks. By independently operating a prefabricated smart factory and leveraging digital intelligent technologies to empower construction, the team gradually resolved blockages across the entire production, transportation, and installation process. Prefabricated component production increased from an initial 24 villas per month to 240, while the quality acceptance rate rose from 75% to 99%. The project team implemented a "1+5" refined operation system (each team managed by one Chinese supervisor coordinating five local workers responsible for hoisting) and established incentive and elimination mechanisms, leading to a leap in hoisting efficiency. The project also developed nine types of first-of-their-kind intelligent construction equipment, including automatic welding robots for embedded parts and automatic inspection systems for concealed works, and adopted the PCMES digital management system for full-process traceability and control of components.
Currently, Phase 3 of the Sedra Project has fully transitioned into the decoration stage. The project team will continue to advance subsequent construction tasks. The smooth progress of this project has accumulated engineering experience for Chinese construction enterprises in the high-standard housing construction sector in the Middle East.
