Yi Feng is a Hong Kong construction subcontractor that provides engineering and site services for private and public sector building and infrastructure projects. The company operates through two primary service lines: civil engineering works and steel cutting services. Its civil engineering operations include designing and installing permanent electrical systems, maintaining temporary site utilities such as power distribution and drainage, and operating vertical material handling equipment like hoists and tower cranes. Under its steel cutting business, Yi Feng dismantles temporary steel structures on active construction sites and sells the recovered scrap steel to recyclers. Yi Feng operates on a project-by-project basis, securing contracts primarily through invitation-based tenders with main contractors and other subcontractors. Its contracts are structured as fixed-price or re-measurement agreements, with revenue recognized over time as work progresses. Yi Feng relies on direct labor, raw materials, and leased equipment to execute contracts. The company aims to grow by expanding its customer base across infrastructure sectors such as transportation and data centers, adopting construction modeling software, and extending operations into mainland China's Greater Bay Area.
