Introduction 3 Title - Project Controls and Performance Management: Energy Retrofit Case Study Subtitle - Applying Earned Value Management (EVM) to an EPC Project Name – Nikhil Sreedharan Nair Role - Project Planning and Controls Manager Company/University [Enova by Veolia] / [Manipal Dubai]
Project Overview & Context (Introduction) Project Context : High-Rise Commercial Energy Retrofit Key Metrics - Project Goal: Guaranteed Energy Savings (AED 932,447 annually) Budget (BAC): AED 4,001,291 Duration: 12 Months Project Type - Energy Performance Contract (EPC) Role Summary - Responsible for Baseline Establishment (P6), Performance Monitoring (EVM), and Reporting. 4
Technical and Controls Objectives Technical Focus Applied Engineering: Gaining expertise in high-value ECMs: Chiller VSD/Replacement and BMS optimization. Goal: Understanding how engineering scope links to guaranteed savings. Controls Focus Project Mastery: Establishing and managing a Performance Measurement Baseline (PMB). Key Tool: Mastering Earned Value Management (EVM) for objective performance forecasting 5
Work Done - Baseline & Planning Title Work Done: Establishing the Baseline (P6) WBS/Scope WBS Structure: Grouped activities into Procurement, Implementation, and M&V stages. PMRs: Defined specific physical milestones for EV calculation (e.g., 50% on site installation). Planning (PV) Critical Path: Defined by 16-week Chiller Procurement/Installation. Strategy: Fast-tracking non-critical ECMs (LEDs) to front-load EV and create schedule float. 6
Work Done - Technical Application Title Work Done: Technical Execution and Control Technical Focus Chiller Plant: Implementation of VSD technology on pumps. Controls: Integration of BMS sequences for optimal start/stop and CHWST reset. EVM Link Used EV as the certified metric for invoicing and ensuring physical progress justified financial claims. 7
Inference - Performance Analysis Inference: Understanding the Project Health Schedule Analysis SPI= 0.89 (RED). Inference: Project is achieving only 89% of the planned work rate, directly caused by the Critical Path (Chiller) delay. Forecast: Time EAC≈13.48 months (1.5-month delay). Cost Analysis CPI= 1.07 (GREEN). Inference: Project earns AED 1.07 for every AED 1.00 spent. Excellent cost efficiency due to early procurement savings. 9
Results - Forecasting & Correction Forecasting, Risk, and Corrective Action Cost Forecast (EAC) Forecast: EAC=AED 3,739,524 (Formula: BAC/CPI) Result: Project is forecast to complete AED 261,767 under budget. Corrective Action Risk: Schedule delay is unacceptable. Action: Implemented Fast-Tracking (overlapping Chiller installation/piping) and Resource Levelling to regain lost time. 10
Conclusion & Key Takeaways 11 Title Conclusion: EVM as the Risk Language Key Takeaways 1. EVM Objectivity: Provides early warning (1.5-month delay) regardless of subjective progress feeling. 2. Financial Protection: Strong CPI protects overall profitability, despite the schedule slip. 3. Controls Imperative: Proactive EVM reporting enabled targeted corrective actions that protected the Critical Path. Future Improvements Recommendation: Implement Monte Carlo Risk Modeling to better forecast procurement uncertainties in future contracts.
