EPC, EPCM, or PMC? Choosing the Right Procurement Strategy

04-Jul-2025

Selecting the right procurement and execution model is one of the earliest and most important decisions for a process plant project. It affects risk, cost control, schedule, and long-term success.

Procurement Managers and Project Managers typically choose among three models:

  • EPC (Engineering, Procurement, Construction)
  • EPCM (Engineering, Procurement, Construction Management)
  • PMC (Project Management Consultancy)

In this article, we explain each model, highlight key differences, and share guidance to help you make the best choice for your process plant.


What is EPCM?

EPCM stands for Engineering, Procurement, and Construction Management. Here, the EPCM contractor does not perform construction work but manages it. The contractor provides:

  • Engineering design
  • Procurement support
  • Construction supervision

The client enters into direct contracts with equipment suppliers and construction subcontractors. The EPCM contractor acts as the owner's agent and provides technical and managerial oversight.

Benefits of EPCM:

  • Greater control over vendors and design
  • Flexibility to adjust scope during the project
  • Transparent cost structure

Challenges:

  • More risk and responsibility rests with the client
  • Requires a strong internal team to manage contracts and decisions

What is EPC?

EPC stands for Engineering, Procurement, and Construction. It is often referred to as a turnkey solution. Under this model, the contractor is responsible for the full delivery of the project. This includes:

  • Design and engineering
  • Procurement of materials and equipment
  • Construction and commissioning

The client provides the project requirements, and the EPC contractor handles the rest.

Benefits of EPC:

  • Single point of responsibility
  • Fixed contract cost and schedule
  • Lower risk to the owner

Challenges:

  • Limited control for the owner over detailed design or vendor selection
  • Variations or changes can be costly

What is PMC?

PMC stands for Project Management Consultancy. In this approach, the PMC firm does not execute the engineering or procurement but manages the entire project on behalf of the owner. A PMC typically oversees multiple EPC or construction contractors.

Benefits of PMC:

  • Strong oversight and governance
  • Independent management across multiple work packages
  • Suitable for large, phased projects

Challenges:

  • Requires coordination among several contractors
  • Owner must make final decisions and approvals
  • Higher demand on internal resources

Understanding the Contract Relationships

EPCM Contract

  • Multiple contracts between the owner and individual suppliers or subcontractors
  • EPCM contractor acts as the owner’s agent
  • EPCM services are typically provided under a reimbursable or fee-based contract
  • Owner retains legal and financial responsibility for each package

This approach offers flexibility and transparency, but the owner must manage risks and approvals throughout the project.


EPC Contract

  • One contract between the owner and the EPC contractor
  • Lump-sum or fixed-price contract is common
  • Contractor takes full responsibility for design, procurement, and construction
  • Owner has limited involvement once the contract is signed

The EPC contract is legally straightforward, but change orders can be expensive if the scope is not well defined at the start.


PMC Contract

  • PMC provides oversight and management under a consultancy agreement
  • The owner signs separate contracts with all engineering, procurement, and construction vendors
  • PMC supports contract administration, progress monitoring, and interface coordination

This model provides strong project governance but places more demand on the owner's internal team to make timely decisions and resolve disputes.

Key Differences: EPC vs EPCM vs PMC

Model Owner's Risk Owner’s Control Cost Certainty Flexibility Typical Use
EPC Low Low High Low Clear scope, tight schedule
EPCM Medium High Medium High Complex scope, evolving design
PMC High High Medium Moderate Large-scale, multi-package projects

Choosing the Right Model for Your Project

  • Is your scope well defined? Choose EPC for fixed outcomes
  • Do you need flexibility during execution? Consider EPCM
  • Are you managing multiple packages or phases? PMC could be the answer
  • Does your team have capacity to make frequent decisions? EPCM and PMC both require strong internal project management
  • Do you want a single point of accountability? EPC offers that benefit

In the process industry, all three models are valid depending on the complexity, risk profile, and maturity of your in-house team.

Final Thoughts

Choosing between EPC, EPCM, and PMC is more than a technical or financial decision. It defines how your project will be executed and how risks will be managed.

Each model has unique strengths. The right choice depends on your goals, internal capacity, and risk appetite.
