Understanding EPC Project Phases (Simple Guide)

To grasp A Guide to the Different Phases of an EPC Project, it’s important to understand that an EPC project involves planning, designing, installing, and maintaining energy-saving solutions. Each phase builds on the previous one. Skipping steps or misunderstanding responsibilities can cause problems.

At an eighth-grade reading level, think of it like constructing a building: you wouldn’t start painting walls before laying the foundation. EPC projects follow a similar step-by-step process to ensure performance, savings, and safety.

Main phases typically include:

  • Preliminary Assessment and Feasibility Study

  • Detailed Energy Audit

  • Design and Engineering

  • Procurement and Contracting

  • Installation and Commissioning

  • Measurement and Verification (M&V)

  • Operation and Maintenance


1. Preliminary Assessment and Feasibility Study

The first step is understanding the project’s potential.

Key activities:

  • Collect basic building and energy data

  • Identify potential energy-saving measures

  • Estimate preliminary costs and savings

Why it matters:

A strong feasibility study ensures the project is viable before committing significant resources.


2. Detailed Energy Audit

A thorough audit pinpoints exactly where energy is used and wasted.

ITA role:

  • Walk through the facility

  • Take measurements and collect data

  • Analyze systems and identify opportunities

Red flags:

  • Relying only on benchmarks or assumptions

  • Skipping real measurements


3. Design and Engineering

This phase develops detailed plans for systems and equipment.

Key points:

  • Select appropriate technologies

  • Prepare drawings and specifications

  • Plan integration with existing systems

Why it matters:

Design determines whether the project will deliver promised energy savings.


4. Procurement and Contracting

Choosing equipment and contracting services comes next.

Important activities:

  • Evaluate bids and supplier options

  • Ensure quality and compatibility of equipment

  • Finalize contracts with clear roles and responsibilities

Tip:

Document everything carefully to avoid misunderstandings later.


5. Installation and Commissioning

Systems are physically installed and tested.

Key steps:

  • Supervise installation closely

  • Conduct functional tests and commissioning

  • Record results and hand over documentation

Red flags:

  • Poor supervision or skipped testing

  • Missing manuals or incomplete documentation


6. Measurement and Verification (M&V)

After installation, energy savings need to be tracked.

Activities include:

  • Set up monitoring systems and meters

  • Compare actual savings against baseline

  • Adjust systems if needed

Why it matters:

M&V confirms that your investment is delivering promised benefits.


7. Operation and Maintenance

Long-term success depends on proper upkeep.

Key tasks:

  • Follow preventive maintenance schedules

  • Train building staff on system use

  • Respond quickly to faults and alerts

ITA contribution:

They often support or audit operations to ensure ongoing performance.


Tips for Managing Risks Across All Phases

  • Involve an ITA early to review designs and plans

  • Keep detailed documentation of all phases

  • Communicate regularly with the project team

  • Watch for deviations from schedules or budgets

  • Verify all systems before final handover


Common Pitfalls to Avoid

  • Skipping detailed audits or measurements

  • Choosing equipment based on price alone

  • Assigning inexperienced staff to critical tasks

  • Ignoring maintenance and monitoring plans


Final Thoughts and Call to Action

Knowing A Guide to the Different Phases of an EPC Project ensures projects run smoothly, deliver real energy savings, and avoid costly mistakes. Following the steps outlined—from assessment to operation—helps building owners and managers make informed, confident decisions.
