This Session 3 video from Data Center Guru explains the complete data center life cycle as a continuous, multi-stage journey that not only builds a facility but sustains its performance and drives ongoing improvement. It begins with requirements and specification definition, followed by rigorous site/location due diligence to assess environmental, man-made risks and resource availability, which feed into design-basis documents and detailed engineering. The project phase then covers drawings, procurement, construction, project management disciplines (scope, contract, communication, stakeholder, cost, quality), and quality planning, culminating in testing and commissioning. Post-handover, operations management takes over with defined SOPs/MOPs/EOPs, performance monitoring, sustainability, and reliability programs to maintain availability and efficiency over the lifespan. The session closes by reinforcing a Plan–Do–Check–Act improvement loop that feeds lessons back into redesign and upgrades, ensuring alignment with business objectives, while setting up the next topic on data center types and evolution.
