The Nampula–Nametil Road Rehabilitation Project was the first project carried out by POSCO E&C in Africa. Despite the extremely inferior environment, POSCO E&C, with only three key members, completed the first overseas infrastructure project. This was a project to rehabilitate the two-lane unpaved road with an extension of 70.65 km between Nampula and Nametil located 2,400 km to the northeast of Maputo, the capital city of Mozambique into an asphalt road through the application of DBST1) technique and to build six bridges along the road. With the construction commenced in December 2017 and completed on time in July 2020, we obtained the taking over certificate (TOC) from the project ordering authority. With the project being the country’s long-cherished wish, the President of Mozambique attended the groundbreaking ceremony in December 2017 and requested successful completion of the project. Currently, the Nampula–Nametil section is opened for traffic, transforming into an inland traffic hub extending through Angoche (sea), Nametil, Nampula, and Nacala (port city) of Mozambique, contributing to the country’s inland economic activation. POSCO E&C not only improved technological power and high-quality construction capacity, but also made a considerable contribution to enhancing Korea’s national prestige. President of Mozambique, Ambassador Yeo Seong-jun to Mozambique, the Governor of Nampula, the Mozambican Public Works Minister, and the president of the ordering authority attended the completion ceremony held in July 2020. They expressed gratitude to POSCO E&C and the relevant officials involved in the project for providing employment opportunities to the local residents, contributing to local economic activation, and giving shape to the government’s strategic vision for developing the region into a hub for inland transportation. This is an exemplary case of POSCO E&C’s successful project completion on time in the new market of Africa.

The 9.14 km section of the Seoul Metro Line 9's Phase 3 construction works (Asian Game Village in Jamsil-dong, Songpa-gu to VHS Medical Center in Dunchon-dong, Gangdong-gu) was divided into two sections: the construction works for section 1 with an extension of 5.94 km (Asian Game Village in Jamsil-dong to Olympic Park Station (Subway Line 5)) were commenced on December 31, 2009; section 2 with an extension of 3.2 km (Olympic Park Station (Subway Line 5) to VHS Medical Center in Dunchon-dong) were commenced in late September, 2010. For the phase 3 project, POSCO E&C worked on Zone 921, which is an extension of 1,710 m (Main Line: 1,380 m; two stations: 330 m, three ventilation systems) from Bangi-dong (Olympic Park South Gate 4) to Olympic Park Station (Korea National Sport University). Through this project, Sports Complex Station in Songpa-gu and VHS Medical Center in Gangdong-gu were connected, shortening the travel time between Gimpo International Airport Station and Olympic Park Station to only 50 minutes. As a result, citizens’ convenience of travel between the eastern and western parts of Seoul has been considerably improved. It contributed to establishing the “golden line” running from Gangseo-gu through the key business districts of Yeouido and Gangnam to Gangdong-gu.

The East Breakwater Construction Works for the Second Stage in Ulleung (Sadong) Port is a very important project that will serve as a trigger for Ulleungdo Island’s development. The East Breakwater of Sadong Port was made by connecting 14 caissons (a concrete structure built to create an underwater structure or foundation), which serve as a frame for the breakwater. In general, caissons are manufactured near a breakwater; however, as it is difficult to supply construction materials in Ulleungdo Island, caissons are manufactured at Yeongilman Port of Pohang, which is 210 km away from the island. It takes nearly 50 hours to transport materials from such a remote port. Therefore, this new project has never been attempted in the construction industry. Having succeeded in manufacturing caissons by 14,000 tons, the largest scale in Korea, and transporting them over a long distance of 210 km from Pohang to Ulleungdo Island, POSCO E&C accomplished the outcome of installing ten caisson units on Sadong Port. We used chloride resistant concrete, which is a new technology. Furthermore, the four patented technologies were applied to ensure excellent bonding between caisson blocks and eco-friendliness to enable the growth of marine algae on the blocks. Detailed attention was paid to prevent back flow of seawater and secure harbor tranquility. Through the project, Sadong Port was able to stably handle large-scale passenger ship and coastal freight transportations were further enhanced. In addition, the settlement conditions for local residents have been improved as a military port for exclusive use by the naval patrol ships and vessels was secured. As such, Sadong Port has gained status as a gateway port to Ulleungdo Island.

The Water Thermal Treatment Plant in Krakow is the largest-scale domestic waste incineration facility in Poland. It handles 220,000 tons of domestic wastes a year, taking in charge for electric power generation and local heating supply. Through field management according to the strict European environmental criteria, POSCO E&C won certification as a “zero-defect and zero-accident” site. Enhancing the status of Korea’s construction technological power, we also raised expectations for entry to the Eastern European environmental market. With POSCO E&C’s completion of the project to build a largest-scale domestic waste incineration facility in Poland, Krakow can environmentally incinerate and treat 220,000 tons of domestic wastes generated each year. It can also generate 11 MWh of electric power using the incineration heat and supply local heating by 35 MWh. The ash remaining after incineration can be recycled to a material for road construction following a sorting process. With the power plant completion, the burden on Krakow posed by the EU’s demand for landfill waste reduction has been lowered. The city can also sell the electric power generated from the plant at a higher price as it obtained the Green Energy certification from the Polish government. In October 2012, POSCO E&C won the contract for the power plant construction in Krakow by winning in competition against CNIM of France, KEPPEL of Belgium, and Hitachi of Japan, the companies holding advanced technologies in incineration plants. Through this accomplishment, we expanded Korea’s construction territory up a notch. Through the construction period of three years and six months, POSCO E&C thoroughly managed the site according to Poland’s strict environmental criteria. As a result, we successfully passed the inspections conducted by Krakow’s labor office and a local environmental protection bureau, winning recognition as a zero-defect and zero-accident site.
