The EPC (Engineering, Procurement, and Construction) Turnkey contracting model, leveraging its advantages in integrated management, has been widely adopted in the engineering construction sector. However, contracts under this model encompass multiple legal relationships involving design, procurement, and construction, where poorly designed clauses are prone to triggering various disputes. Based on the core characteristics of EPC Turnkey contracts, this paper focuses on analyzing the legal implications and practical essentials of key clauses concerning contract validity, joint venture liability, payment settlement, change management, and claim procedures. It examines potential legal and commercial risks associated with these clauses and proposes targeted risk prevention strategies informed by industry practice, aiming to provide references for construction entities to standardize contract management and mitigate performance risks.
