The cutaway is an illustrative systems diagram. It helps organize trade scopes, ownership and testing, but does not specify the final architecture, equipment locations, service voltage, cooling topology or code compliance of a selected site.

Planning data & boundaries

Work package	Proposed scope boundary	Key interface
Site civil / drainage	Earthwork, roads, drainage, underground services	Parcel hydrology, utilities and equipment-yard access
Shell / architectural	Structure, enclosure, roofing, doors and support spaces	Tenant loads, maintainability, fire/smoke and security assemblies
Electrical / standby	MV/LV distribution, UPS, standby fuel, switchgear and busway	Utility protection, cooling/controls loads and tenant rack connections
Mechanical / cooling	Heat collection, distribution, rejection and support HVAC	Tenant/CDU demarcation, water, residual air and redundancy
Controls / fire / security	Facility monitoring, detection/suppression and access	Operator duties, tenant IT boundary and integrated controls
Campus HV substation	Foundations, equipment, protection and metering	Utility / owner scope, corridors, voltage and energization
Off-site interfaces	Grid, diverse fiber, water/sewer and road tie-ins	Service agreements, easements, capacity and permits

Define the interfaces before buying equipment

Use one responsibility matrix to separate utility work, owner work, trade scope, facility controls and tenant equipment. Confirm who supplies rack CDUs, busways, connections, controls integration, testing and spares. The illustration does not prove that different vendor systems will work together.

Procurement and live-phase construction

Prioritize the actual utility path and long-lead equipment only after adequate technical/commercial gates. Preserve cancellation controls and allocate escalation and delay risk. Phase 2 work requires safe physical and operational separation from live Phase 1 power, cooling, access and security.

Commissioning and turnover

The proposed sequence is design review, factory acceptance, receipt checks, installation and prefunctional checks, energized/integrated tests, then operator and tenant acceptance. Include approved failure scenarios, defect closure, training, emergency procedures, spares and record documents. Physical completion alone is not ready-for-service.

Permit, noise and safety scope

Build the actual municipal, county/regional, Illinois and federal applicability register for the parcel and operating modes. Separately evaluate fuel/battery hazards, emissions, water, noise, utility obligations and worker safety. The engineering teams and authorities must establish the final requirements; the illustration is not permit evidence.
