1. Purpose and Scope
This reference defines the operating boundary framework for GridCore campuses. It is not a final operations manual, emergency response plan, staffing plan, MSA, SLA, security plan, NERC determination, compliance plan, or site-specific SOP.
It is intended to align campus owner, platform operator, colocation operator, powered land customer, powered shell customer, EPC, vendors, security team, safety team, facilities team, power team, carriers, and commercial teams on how operating responsibilities are divided across a complex, multi-domain campus.
Final operating boundaries must be documented in site-specific procedures, contracts, training materials, and escalation matrices. This reference establishes the framework for those project-specific documents.
2. Operating Model Premise
"Integrated infrastructure fails at the boundaries before it fails in the org chart."
Individual teams may be competent in their domains, but interface failures create the most consequential operational risk. Power, cooling, security, network, safety, and customer operations are deeply interdependent on a modern compute campus.
- —AI and HPC loads create dynamic, real-time operating conditions that can interact across systems unexpectedly.
- —Campus-scale infrastructure requires formal authority boundaries — not informal agreements between team leads.
- —Operations must define procedures for normal, abnormal, maintenance, emergency, and customer-caused conditions before the campus is energized.
- —A boundary that exists only in someone's head is not a boundary.
3. Operating Domains
A GridCore campus may encompass all of the following operating domains. Each domain has a primary function, typical owner, interfaces with other domains, and a system of record for evidence.

| Customer equipment fault | Customer Support | Customer, ops team | Confirmed impact to campus infrastructure | Immediate customer contact required |
| Severe weather watch/warning | Ops Lead / EHS | All campus staff, customers | Issued watch for campus area | Advance customer notification per plan |
7. Emergency Operations Boundary
Emergency authority must be pre-defined and understood before any emergency occurs. Life safety overrides all commercial considerations. Emergency responders assume control within their statutory authority and must be supported, not managed.
- —Campus incident command must be designated before first energization.
- —Emergency shutdown authority must be explicit — who can de-energize what, under what conditions.
- —Communication channels during emergencies must be controlled and documented, not ad hoc.
- —Customer representatives should be identified in advance and their emergency role defined.
| Emergency Type | Incident Lead | Technical Lead | Safety/Security Lead | Customer Role | External Party Interface |
|---|---|---|---|---|---|
| Fire | Incident Commander | Facilities / Building Ops | EHS + Security | Evacuate; designated contact | Fire department leads on-site |
| Injury / medical | EHS / Safety Lead | Operations | Security (access for EMS) | Notified if in customer area | EMS and emergency services |
| Electrical arc flash or shock | EHS / Safety + Power | Campus Power | EHS isolates area | Evacuate if adjacent | EMS; utility if MV event |

| Environmental release | EHS Lead | Facilities | EHS | Notify if in affected area | Regulatory agencies as required |
| Security threat | Security Operations Lead | Operations | Security | Secure customer areas; restrict movement | Law enforcement |
| Severe weather / tornado | Ops Lead | Facilities + Power | Security + EHS | Shelter-in-place notification | NOAA / local emergency management |
| Cybersecurity incident affecting operations | OT Security / IT Security | Controls team | IT Security | Notify if customer data or systems affected | Cyber incident response, legal if required |
| First responder site access | Security / Ops Lead | Facilities | Security manages escort | No role unless their area | Fire, EMS, or law enforcement as applicable |
8. Power Operations Boundary
Power operations spans source monitoring, switching, protection event management, metering, maintenance isolation, load release, and emergency response. Each function requires a defined owner, procedure, and evidence record.
| Power Function | Campus Power Team | Facilities / Building Team | Customer | Required Procedure |
|---|---|---|---|---|
| Source status monitoring | Owns and monitors | Receives alarms | Read-only visibility per contract | Monitoring SOP |
| Feeder switching | Owns; qualified switching authority required | Notified before switching | Notified if customer-impacting | Written switching procedure |

| Customer load increase | Reviews campus capacity impact | Reviews building capacity | Submits request per change process | Capacity change procedure |
| Power quality investigation | Leads MV/LV investigation | Supports building-level analysis | Provides load profile data | Power quality event procedure |
9. Cooling Operations Boundary
Cooling operations require clear boundaries between campus-owned systems and customer-interfacing systems, particularly for high-density liquid cooling deployments where the demarcation between CDU and customer rack can involve significant safety and liability considerations.
| Cooling Function | Operator Scope | Customer Scope | Coordination Trigger | Evidence / Monitoring |
|---|---|---|---|---|
| Plant operation | Campus owns entirely | No role | Customer load changes affect plant setpoints | BMS, plant SCADA |
| Loop pressure/flow | Campus monitors and maintains | No direct access | Excursion triggers notification | BMS historian, flow records |
| Temperature setpoint | Campus controls per SLA | May request adjustment per contract | Customer load step or thermal alarm | BMS setpoint log |
| Fluid chemistry | Campus owns and maintains | No role | Contamination or system expansion | Chemistry test records |
| Leak detection | Campus monitors system-wide | Customer monitors within racks if liquid-cooled | Any confirmed leak — immediate escalation | Leak detection system, BMS |
| CDU alarms | Campus operates CDUs | Receives notification of customer-side alarms | CDU fault or thermal limit | BMS alarm log, maintenance records |
| Rack-level cooling | Campus not responsible inside customer rack | Customer owns rack-level components | Thermal excursion from customer load | Customer DCIM, campus BMS trend |

| Cooling capacity expansion | Campus leads design and installation | Customer may fund or request | New load commitment or customer upgrade | Project records, commissioning |
10. OT/IT and Monitoring Boundary
OT systems are operational infrastructure, not ordinary enterprise IT. They directly control physical systems — switchgear, transformers, cooling pumps, UPS, fire suppression, and access control. Treating them as standard IT creates safety and security risk.
| System | Data Visibility | Control Authority | Cybersecurity Boundary | Escalation Owner |
|---|---|---|---|---|
| SCADA | Operations and authorized management | Qualified operators only | Segregated OT network; no direct internet exposure | OT Security / Ops Lead |
| EPMS | Operations; customer read-only per contract | Campus power team only | OT network; audited remote access | OT Security / Power Lead |
| BMS | Operations; customer portal view where contracted | Facilities / controls team only | OT network; change-controlled | OT Security / Facilities Lead |
| Fire / life safety monitoring | Security operations, EHS, Ops Lead | AHJ-approved personnel only | Isolated system; audited access | EHS / Facilities |
| Security / access control | Security operations only | Security operations only | Dedicated security network | Security Lead |
| CCTV | Security; legal / HR for incident review | Security operations only | Security network; retention policy | Security Lead |
| Tenant portal | Customer read access to scoped metrics | No control; read-only portal | Customer-facing DMZ; isolated from OT | IT / Ops |
| Customer DCIM integration | Customer visibility into agreed data points | No campus control from customer side | API boundary; authenticated and audited | IT / OT Security |
| Carrier portal | Connectivity team | Connectivity team only | Carrier-managed; campus-side demarcation | Connectivity / IT |
| Ticketing system | Ops, customer support, customers | Operations / support team | Standard enterprise security | IT / Ops |
11. Security Operations Boundary
Physical security is an operating domain, not a vendor service. Access control, visitor processing, escort requirements, CCTV management, incident response, and law enforcement coordination must be procedurally defined and actively managed.
| Security Activity | Security Team | Facilities / Ops | Customer | Recordkeeping |
|---|---|---|---|---|
| Visitor approval | Owns final authorization | Coordinates work-area access | Submits request; provides sponsor | Visitor log, approval record |
| Contractor access | Validates credentials and authorization | Confirms work order/PTW | No role unless their vendor | Contractor log, PTW record |
| Tenant access | Issues and manages credentials | Supports area designation | Manages their own staff lists | Badge system, access log |
| Delivery routing | Controls entry; screens if applicable | Receives delivery in authorized area | Coordinates expected deliveries | Delivery log |
| Badge issuance | Issues, activates, deactivates | Provides area access requirements | Requests badges per process | Badge system log |
| Escort assignment | Assigns escort for non-credentialed visitors | Supports in facilities areas | No direct role | Visitor log, escort sign-off |
| CCTV review | Security operations only | No access | No access | Viewing log; incident request records |
| Security incident | Leads response; law enforcement interface | Supports evacuation or lockdown | Directed by security/ops during incident | Incident report, access log |
| Restricted area exception | Approves with escalation | Documents work justification | May request for specific work | Exception request, approval record |
| Access audit | Conducts periodic access review | Provides area changes and staff changes | Validates their own access list | Audit report, corrective actions |
12. Customer Operations Boundary
Customer operating scope varies significantly by commercial model. The boundaries below describe how responsibility differs across offering types.
Powered Land Customer
- —Owns and operates all systems inside their facility
- —Responsible for load profile compliance
- —Responsible for their own safety and security within their boundary
- —Interfaces with campus via delivery point, metering, and escalation matrix
- —Must coordinate planned load changes and construction activity
Powered Shell Customer
- —Campus provides building shell and power to designated points
- —Customer installs, owns, and operates IT, cooling, and systems within shell
- —Customer responsible for internal safety and building systems compliance
- —Interfaces with campus for power, access, connectivity, and carrier services
- —Must coordinate any work affecting shared systems
Turnkey Colocation Customer
- —Campus operates all shared infrastructure, cooling, power, and building systems
- —Customer installs and operates IT equipment only within defined rack/cage
- —Customer responsible for equipment installation, operation, and compliance to facility rules
- —Access managed by campus security; customer credentials issued

Carrier / Network Provider
- —Authorized to access demarcation and meet-me room only
- —No access to compute or power infrastructure
- —Coordinates with campus connectivity team for any network work
- —Must follow visitor/contractor rules for any physical access
- —Escalation through campus connectivity team
13. Change Management Boundary
All changes to campus infrastructure, systems, configurations, load profiles, or access rights must be classified and approved before execution. Uncontrolled changes are a leading cause of outages.
| Change Type | Approval Owner | Notice Requirement | Customer Impact Review | Backout Requirement |
|---|---|---|---|---|
| Emergency change | Ops Lead / Incident Commander | Post-hoc notification | Assess during; notify immediately if impacting | Document in incident record |
| Standard change | Pre-approved per change library | Per standard cadence | Only if on pre-approved impact list | Standard backout procedure |
| Normal planned change | Change management board or designated owner | Minimum advance notice per SLA | Full impact assessment required | Written backout plan required |
| Customer-impacting change | Change board + account management | Per contract change notice period | Customer approval required | Customer-acknowledged backout plan |
| Security-sensitive change | Change board + security lead | Security clearance required | Assess customer area impact | Security team validates restoration |
| OT/control system change | Change board + OT security | Pre-work window required | Assess monitoring/control impact | Control system restore procedure |
| Power system change | Change board + switching authority | Written switching procedure required | Customer power impact assessment | Restoration switching sequence |
| Cooling system change | Change board + cooling lead | Thermal risk assessment required | Thermal impact to customer areas | Cooling restore procedure |
| Network change | Change board + IT/OT leads | Connectivity impact assessment | Customer connectivity impact review | Network restore procedure |
| Commercial capacity change | Account management + ops + commercial | Contract amendment required | Part of commercial process | N/A — commercial action |
14. Incident Management and Escalation
All incidents must be classified by severity on first contact and managed through a defined escalation model. Severity determines communication cadence, escalation path, and closeout requirements.
| Severity | Example Conditions | Required Escalation | Communication Cadence | Closeout Requirement |
|---|---|---|---|---|
| SEV 1 — Critical | Life safety event; major outage; critical shared infrastructure failure | Incident Commander + executive leadership immediately | Continuous until stable; then 30-min updates | Post-incident review; root cause; corrective actions with due dates |
| SEV 2 — Major | Degraded redundancy; major customer-impacting risk; extended maintenance condition | Ops Lead + department heads + customer account manager | Hourly updates until resolved | Incident report; root cause; corrective actions tracked to closure |
| SEV 3 — Minor | Localized issue; non-critical alarm; controlled maintenance situation | Ops Lead; notify department lead | Updates at key status changes | Work order closeout; corrective action if applicable |
| SEV 4 — Informational | Minor service request; no impact; informational alarm | Ticket owner | Response per SLA | Ticket closure and resolution documented |
15. Documentation and System of Record
Operating boundaries must be reflected in current, accessible documentation. Stale documentation is an operational hazard — teams revert to tribal knowledge, boundaries blur, and incidents compound.
16. Governance and Review Cadence
Boundary matrices should not be static documents. They must be reviewed and updated when the campus changes — new customers, new infrastructure, incidents, expansions, or operational experience all trigger review.
| Review Trigger | Participants | Output |
|---|---|---|
| New customer onboarding | Ops, account management, customer, security, power, cooling | Updated customer interface matrix; new escalation contacts |
| New building commissioned | All domain leads, commissioning manager | Updated operating domain matrix; new procedures |
| Major power system change | Power, controls, OT security, ops lead | Updated switching procedures; revised authority records |
| Major cooling system change | Cooling lead, facilities, ops lead | Updated cooling boundary procedures |
| Security incident | Security, ops, EHS, legal if applicable | Updated security procedures; corrective actions |
| Emergency drill / exercise | All domain leads, EHS, security, account management | Updated emergency plan; training gap corrections |
| Post-incident review | All teams involved in incident | Root cause report; boundary corrections; updated procedures |
| Annual governance review | Ops management, all domain leads, account management | Full boundary matrix review; annual sign-off; update log |
