Six phases.
Named deliverables
at every one.
You should know what lands on your desk at the end of each phase before you sign anything. Here is the sequence, and what comes out of it.
Discovery
Understand the site before proposing anything for it.
Site survey, utility position, structural and envelope constraints, water and climate, workload profile, tenant and SLA obligations, permitting authority. We write down what we do not yet know as explicitly as what we do.
- [✓]Site condition report
- [✓]Constraint register
- [✓]Open-questions log
Load model
Every downstream number scales from this one.
IT load, rack density and count, PUE target by cooling approach, facility load, heat rejection, redundancy factor, utility service requirement, and battery energy. Each figure carries its worst-case assumption in writing.
- [✓]Power and thermal load model
- [✓]Redundancy basis of design
- [✓]Utility service requirement
Single-line and layout
Where everything physically goes, and how power reaches it.
Electrical single-line from service entrance to rack PDU, cooling loop schematic, white-space and support-space layout, battery and switchgear siting, cable and pipe routing, service access and clearances.
- [✓]Electrical single-line
- [✓]Mechanical schematic
- [✓]Floor and site layout
Redundancy and FMEA
Assume every part fails, then see what survives.
Component-level failure mode and effects analysis: how each part fails, what happens when it does, how likely, how detectable, how severe. Single points of failure get designed out or explicitly accepted in writing, never discovered later.
- [✓]FMEA workbook
- [✓]Single-point-of-failure register
- [✓]Independent design review
Procurement
The schedule is set by whatever has the longest lead time.
Specification and sourcing of transformers, switchgear, UPS and battery systems, CDUs and cooling plant, racks and PDUs. Vendor evaluation against the specification rather than against the sales deck, plus lead-time tracking against the critical path.
- [✓]Bill of materials
- [✓]Vendor evaluation matrix
- [✓]Long-lead schedule
Build and commissioning
Nothing is proven until it is measured under load.
Trade coordination, integration, and a commissioning sequence that tests the failure modes rather than assuming them: transfer events, thermal performance at design load, alarm and monitoring verification. Measured results, not design intent.
- [✓]Commissioning scripts and results
- [✓]As-built documentation
- [✓]Operations handover pack
Phase one starts with a questionnaire.
Three minutes, and you get the first cut of the load model back immediately.
