This Session 10 video from Data Center Guru lays out the data center design journey—how requirements and due?diligence inputs flow into master planning, concept design, and finally detailed design that can be built and operated with confidence. It explains collecting clear business, IT, and operational requirements; creating a master plan for greenfield or retrofit sites; using concept design to evaluate options and trade?offs; and producing detailed drawings, specifications, and coordinated multidisciplinary packages for construction and commissioning. The talk maps roles and skills across architecture/structural, electrical power, mechanical cooling, safety/security, and automation/BMS/EMS, stressing the solution architect, project manager, and domain SMEs for integration quality, compliance with codes/standards, and future scalability and serviceability.
