What POSCO E&C does

POSCO E&C (포스코이앤씨) is a South Korea-based construction and engineering company and a wholly-owned subsidiary of POSCO Holdings, headquartered in Pohang with a secondary office in Incheon. Founded in 1982 and rebranded in 2023 from POSCO Construction (포스코건설), the firm operates across four business segments: Plant (steelmaking, power generation, chemicals, nuclear power, LNG terminals), Infrastructure (roads, bridges, railways, subways, ports, water and environmental facilities), Building (urban development, housing, urban regeneration, remodeling, super-tall buildings, commercial and cultural facilities), and Future New Business. Project wins are secured through competitive public and private tenders, direct negotiation with developers and housing associations, and group-level collaboration within the POSCO conglomerate — particularly leveraging POSCO's proprietary high-manganese steel for LNG terminal design and construction. Notable project awards include the KRW 1.3 trillion Seongnam bank employee housing redevelopment and the Sinbanpo 19th & 25th Complex in Seoul.

The company's flagship consumer brand is The Sharp (더샵), a premium residential apartment line ranked #1 in the Korean Brand Customer Loyalty Survey for 9 consecutive years. The Sharp integrates smart home services for seniors and disabled residents, and AI-based healthcare services through a partnership with healthcare provider ARK (MOU signed 2026-03-13). Industrial technology differentiation is anchored by POS-VISION, a drone-based computer vision system that detects cracks as small as 0.3mm — validated across 9 projects — and by a proprietary autonomous cleaning robot deployed on construction sites. Sales and marketing are primarily corporate: the company runs a corporate website, YouTube ('DIVE IN PENC' series), Instagram, and a newsroom that distributes press releases in Korean. Revenue is project-based B2B, with contracts ranging from billions to trillions of KRW on multi-year terms, and the company employs 5,001–10,000 people across its offices in South Korea.
