Master Project Schedule

The critical path for the CCPP project typically runs through the following activities:

1. Project Development Phase

   • Environmental permitting
   • Power purchase agreement negotiation
   • Financial close

2. Engineering Phase

   • Process design basis development
   • Major equipment specifications
   • Detailed engineering of critical systems

3. Procurement Phase

   • Gas turbine procurement (longest lead item)
   • Steam turbine procurement
   • HRSG procurement

4. Construction Phase

   • Major foundations
   • Gas turbine installation
   • Main piping systems
   • Electrical systems

5. Testing & Commissioning Phase

   • Gas turbine commissioning
   • HRSG commissioning
   • Steam turbine commissioning
   • Performance testing

Project Development → Engineering

• Environmental permits must be secured before detailed engineering can be completed
• Project financing must be in place before major equipment can be ordered
• Site selection and geotechnical studies must be completed before foundation design

Engineering → Procurement

• Equipment specifications must be completed before purchase orders can be placed
• Vendor document requirements must be defined before vendor engineering starts
• Material specifications must be finalized before bulk materials can be ordered

Procurement → Construction

• Long-lead equipment delivery schedules drive construction sequencing
• Vendor drawings must be approved before installation can begin
• Material deliveries must align with construction needs

Construction → Testing & Commissioning

• Mechanical completion of systems is required before pre-commissioning
• Electrical completion is required before energization
• Control system completion is required before integrated testing

High-Risk Areas

1. Environmental Permitting: 2-month contingency included
2. Gas Turbine Delivery: 1-month contingency included
3. Weather Impacts on Construction: 2-week contingency per quarter during construction
4. First Fire and Commissioning: 2-week contingency included

Contingency Allocation

• Overall project contingency: 3 months
• Engineering phase contingency: 1 month
• Procurement phase contingency: 1.5 months
• Construction phase contingency: 1.5 months
• Commissioning phase contingency: 1 month

1. Schedule Updates

   • Weekly progress updates during construction and commissioning
   • Bi-weekly updates during engineering and procurement
   • Monthly executive reporting throughout project

2. Change Management

   • Formal change control process for schedule modifications
   • Impact analysis required for all schedule changes
   • Approval levels based on magnitude of schedule impact

3. Recovery Planning

   • Trigger points identified for recovery plan development
   • Resource acceleration options identified for critical activities
   • Alternative execution strategies identified for high-risk areas

4. Progress Measurement

   • Physical progress measurement for construction activities
   • Earned value tracking for all phases
   • S-curves for planned vs. actual progress tracking

This master schedule was developed by integrating the detailed schedules from each project phase:

1. Engineering Phase Schedule: 67-week detailed schedule with 29 key activities
2. Procurement Phase Schedule: 82-week detailed schedule with 82 key activities
3. Construction Phase Schedule: 120-week detailed schedule with 60 key activities
4. Testing & Commissioning Schedule: 60-week detailed schedule with 49 key activities

The integration process involved:

• Aligning key interface milestones between phases
• Ensuring logical relationships between dependent activities
• Optimizing the overall schedule through strategic overlapping of phases
• Validating the critical path across all project phases
• Allocating appropriate contingencies based on risk assessment

This master schedule provides a comprehensive framework for managing the entire CCPP project lifecycle, ensuring all phases are properly coordinated and integrated to achieve the target commercial operation date.
