Developing a Time and Execution Schedule for a Power Generation Plant Project Using Primavera P6

Introduction:

In the field of mega construction projects, especially those related to power generation, a well-structured time schedule is the backbone of successful execution. Primavera P6 is one of the most powerful project management tools widely used for such complex undertakings.

In this article, I’ll walk you through how to develop a time and execution schedule for a Power Generation Plant using Primavera P6—from planning to monitoring.

1. Understanding the Project Scope

Before starting the schedule, it’s crucial to fully define:

Type of power plant (Gas, Diesel, Combined Cycle, Solar, etc.)

Key components: turbines, generators, transformers, control rooms, civil works

Main phases: site preparation, foundations, electromechanical installations, testing & commissioning

2. Work Breakdown Structure (WBS)

Create a hierarchical WBS that divides the project into manageable components:

Level 1:

Project Name

Level 2:

Engineering, Procurement, Construction, Commissioning

Level 3:

Civil, Mechanical, Electrical, I&C, etc.

3. Activity Definition

Each WBS element is broken into activities:

Mobilization

Excavation

Foundation & Concrete Works

Steel Erection

Equipment Installation (e.g., turbines, boilers, switchgear)

Cabling and Testing

Pre-commissioning & Final Handover

4. Duration Estimation & Sequencing

Estimate duration using historical data or expert input

Define logical relationships (FS, SS, FF, etc.)

Use lags/leads where necessary

5. Resource and Cost Loading

Assign resources (manpower, equipment, materials)

Input estimated costs per activity to generate cost-loaded schedules

Enables Earned Value Management (EVM)

6. Milestones and Key Dates

NTP (Notice to Proceed)

Civil Works Completion

First Turbine Ready

Grid Synchronization

PAC (Provisional Acceptance Certificate)

7. Baseline and Tracking

Once approved, baseline the schedule

Use regular updates to track progress (weekly/monthly)

Compare actual vs planned to identify delays or risks

8. Reports and Dashboards

Generate Gantt charts, S-Curves, resource histograms

Present progress to stakeholders clearly and visually

Conclusion:

Primavera P6 provides unmatched capabilities for scheduling, managing, and controlling large-scale power plant projects. With proper WBS, activity definition, and progress tracking, it ensures timely delivery, cost control, and smooth execution.
