Data centers designed around the hardware they will hold. A data center is designed backwards from the equipment it will run: how many kilowatts per rack, how much heat, how much weight and how many fibers. We start there, then plan white space, power distribution, cooling, cabling, containment, monitoring and physical security, working with the facility engineers and contractors who build the mechanical and electrical plant. The result is a room that can be expanded without being redesigned. Where it usually starts: - A server room has grown into a data center without ever being designed as one. - Planned hardware needs more power or cooling per rack than the room can provide. - Cabling is undocumented, and every change risks an outage. - A new facility or colocation suite must be ready for a fixed go-live date. What is included: - Capacity planning: Power, cooling, space and network demand modeled from the planned equipment. - White space layout: Rack placement, hot and cold aisle containment, and clearances. - Power distribution: UPS, PDUs and redundant feeds sized and coordinated with electrical contractors. - Cooling coordination: Air or liquid cooling chosen and designed with mechanical engineers. - Structured cabling: Copper and fiber plant designed, installed and labeled to standard. - Monitoring and security: Environmental monitoring, DCIM, access control and CCTV. Where it sits: Design and build own the facility layer of the data center architecture: power, cooling and the data hall itself, sized for the racks and AI compute that will run there. Decisions to settle early: - Build, refit or colocate. Building your own room gives control; refitting an existing one is cheaper; colocation moves the facility risk to an operator. The load, the timeline and the capital available decide. - Air or liquid cooling. Air cooling is simpler and suits moderate density; liquid cooling suits accelerated systems. Many rooms need both, in separate zones. - How much redundancy. Every redundant feed and unit costs money. The design matches redundancy to what an outage would cost the business. How the work runs: Plan, Demand modeled from the equipment. Design, Layout, power, cooling and cabling. Build, Installation coordinated with contractors. Commission, Tested at load before handover. How it is bought: - A fixed-fee assessment: We model power, cooling, space and network demand from your planned equipment and survey the existing room or site. You receive the capacity model, the constraints and a fixed design price. - A fixed-price build: Design, coordination with electrical and mechanical contractors, cabling and commissioning for the scope agreed, priced before work starts. - Running it afterwards: After handover, monitoring and on-site support can continue under our colocation and smart hands service. Worked example, a server room that became a data center. Say a university's research computing has grown into a room never designed for it: racks are full, cooling struggles in summer, and new GPU servers need more power per rack than the room can deliver. - Model: We model power, heat, weight and network demand from the planned equipment and the expected growth in research, rather than from the current room. - Design: A new layout with aisle containment, higher density rows for accelerated systems and a structured cabling plant is drawn and agreed. - Coordinate: The electrical and mechanical engineers design the power and cooling plant against our load model, and we check their designs against the IT need. - Commission: The finished room is tested under load with heat load banks before any research system moves in, and the as-built drawings are handed over. At the end, the university has a room designed for the equipment it will run, space to grow without a redesign, and documentation that matches what was built. (An illustration, not a client account.) What you have at the end: - Capacity and growth model: Power, cooling, space and network demand from the planned equipment, and how it grows over the life of the facility. - Layout and rack elevation drawings: Rack placement, aisles, containment and clearances, and the position of each device in each rack. - Power and cooling design coordination: The IT load and redundancy given to the electrical and mechanical engineers, and their designs checked against it. - Cabling design and test results: The copper and fiber plant as designed and as installed, with the test results for every link. - Commissioning report and as-built documentation: How the room performed under load before handover, and drawings that match what was built. Standards and platforms worked with: ANSI/TIA-942, EN 50600, ASHRAE TC 9.9, ANSI/TIA-568, ANSI/TIA-606, ISO/IEC 11801, Uptime Institute Tier concepts. Where it goes wrong, and what we design out: - Designing for today's load. A room sized for current equipment is outgrown by the next refresh. Pathways and capacity are sized for the end state. - Cooling decided last. High density racks fail on heat, not space. Cooling is chosen with the equipment, not after it. - Drawings that drift. As-built documentation that does not match the room misleads every later change. Drawings are updated at handover. What it changes: - Room to grow. Capacity is planned for the next generation of equipment, not just the current one. - Fewer single points of failure. Redundancy is designed into power, cooling and network paths from the start. - Documentation that matches reality. As-built drawings and cabling records make every future change safer. How you will know it is working: - The room supports the planned density without hot spots. - Expansion means installation, not redesign. - Commissioning tests passed under load before handover. - Drawings match what is installed. Who you work with: - Data center architect. Models capacity and designs the layout, power distribution, cooling and cabling. - Project engineer. Coordinates the electrical and mechanical contractors and keeps the build to the design. - Commissioning engineer. Tests the room under load and signs off the as-built documentation. What we need from you: - The equipment you plan to run, now and over the coming years. - Drawings and surveys of the existing room or site. - Your electrical and mechanical contractors, if you have them. - The date the room must be ready. Common questions: Q: Do you build the electrical and mechanical plant? A: We design the IT space and coordinate with licensed electrical and mechanical contractors who build the plant, so the requirements of the equipment drive their design and nothing is lost between trades. Q: Can you design for high density AI racks? A: Yes. Racks of current accelerators can draw several times the power of a typical enterprise rack, which changes power distribution, cooling and floor loading. We design those zones separately from general purpose space. Q: Which standards do you design to? A: ANSI/TIA-942 and EN 50600 for data center infrastructure, ASHRAE guidance for thermal conditions, and TIA and ISO cabling standards, applied at the level of resilience the business actually needs. Q: Can you work in an existing, live facility? A: Yes. Work in live spaces is planned around change windows, with method statements and rollback agreed with the facility operator before anything is touched. Q: What is hot and cold aisle containment? A: A layout in which racks face each other so cold air is delivered to a shared aisle and hot exhaust is collected on the other side, with physical barriers that stop the two mixing. It makes cooling more efficient and predictable, and it is often the cheapest way to raise the density a room can support. Q: How do you plan for growth in a new facility? A: By designing the full capacity the site can reach and building it in phases. Power, cooling and cable pathways are sized for the end state, and equipment is added as demand arrives, so expansion is installation rather than redesign. Q: What is DCIM? A: Data center infrastructure management: software that tracks assets, space, power and environmental conditions across a facility. It shows where capacity remains, warns when conditions drift, and keeps the record of what is installed where. Q: Can you design to a particular Uptime Institute tier? A: We design to the redundancy and maintainability concepts the tiers describe, and to ANSI/TIA-942 and EN 50600. Formal tier certification is awarded by the Uptime Institute itself, and where a client wants it, the design is prepared for that review. Often paired with: AI data centers and GPU clusters, Data center networking, Hardware and rack integration. --- Canonical page: https://www.expandware.com/services/data-centers/data-center-design-and-build/ Site index for machines: https://www.expandware.com/llms.txt Full site text: https://www.expandware.com/llms-full.txt Expandware Private Limited.
