Engineering, Procurement, and Construction (EPC) is a prominent form of contracting that provides comprehensive turnkey services in various industries, including construction, oil and gas, energy, and infrastructure. This model is favored for its capacity to deliver fully completed projects from conception to completion.
What Is EPC?
Definition
EPC stands for Engineering, Procurement, and Construction. It is a form of contracting where a single entity, the EPC contractor, is responsible for the entire project lifecycle, including design (engineering), sourcing of materials and equipment (procurement), and the actual building activities (construction). The EPC contract is thus a turnkey contract, implying that the project owner can effectively “turn the key” to a complete, operational facility upon project completion.
Key Components
- Engineering: This phase involves detailed project design, including structural design, specifications, and preparation of all necessary plans and documentation.
- Procurement: involves sourcing and purchasing all materials, equipment, and services necessary for construction as per the design specifications.
- Construction: This is the phase where the physical building occurs, ensuring the design is executed precisely using the procured materials and equipment.
EPC Contract Types
Lump-Sum Turnkey
In this type, the contractor agrees to deliver the complete project at a fixed price, covering all aspects from design to construction, thereby minimizing the financial risk to the project owner.
Cost-Plus
The project owner agrees to reimburse the EPC contractor for all incurred costs plus a specified profit margin. This type is less common in EPC contracts due to the lack of cost certainty for the owner.
Special Considerations
Risk Management
Given the all-encompassing nature of EPC contracts, the contractor bears significant risks, including design flaws, procurement delays, and construction issues. Careful planning and robust risk management strategies are crucial.
Project Timelines
EPC contracts are often preferred for projects with strict timelines because the single contractor approach streamlines coordination and decision-making, potentially reducing project duration.
Historical Context
The EPC model has historical roots in large infrastructure and industrial projects since the mid-20th century when the need for streamlined, integrated project delivery methods became crucial. It has grown significantly in sectors such as oil and gas, power generation, and large-scale infrastructure projects.
Applicability
EPC contracts are particularly useful in:
- Energy: Power plants, renewable energy sites.
- Oil & Gas: Refineries, pipelines.
- Infrastructure: Bridges, highways, airports.
Comparisons and Related Terms
EPC vs. EPCM
While EPC entails turnkey project delivery, EPCM (Engineering, Procurement, and Construction Management) involves the contractor managing the project on behalf of the owner rather than taking full responsibility for the completion.
Turnkey Projects
Turnkey refers to a project delivered in a ready-to-use state. EPC is a type of turnkey project where the contractor handles all aspects until the project is operational.

Summary
EPC contracts are a comprehensive and efficient contracting model encompassing engineering, procurement, and construction. They provide a streamlined approach to project delivery, especially for complex and large-scale projects, offering significant advantages in terms of risk management, cost control, and project timelines. By understanding the nuances and applications of EPC contracts, project owners and contractors alike can better manage and execute their projects successfully.
