- Review and approve vendor-submitted FAT procedures prior to testing, ensuring alignment with project specifications, Uptime Institute Tier standards, and client-specific requirements
- Develop and distribute FAT schedules, witness notifications, and travel logistics for internal teams, client representatives, and third-party commissioning agents (CxAs)
- Attend and lead witness tests at manufacturer facilities, documenting results, managing non-conformance reports (NCRs), and driving punch list resolution
- Ensure all test data packages, certificates of conformance, and factory test reports are complete and submitted per project documentation requirements
- Coordinate re-test scheduling with vendors where equipment fails to meet acceptance criteria, managing impacts to overall project schedule

### Test Procedure Review & Development
- Lead the review, development, and approval of Level 1 through Level 5 commissioning test procedures across all critical systems, including electrical distribution, standby power, mechanical cooling, controls, DCIM/BMS integration, and security/access systems
- Ensure procedures align with ASHRAE, TIA-942, Uptime Institute, and applicable NEC/NFPA standards, as well as owner-specified commissioning requirements
- Coordinate interdisciplinary procedure reviews with MEP engineers, IT infrastructure teams, controls specialists, and HSE representatives
- Maintain a master commissioning procedure register, tracking revision status, approval workflows, and issue-for-construction releases
- Issue approved procedures to field commissioning teams, providing technical clarification and support during integrated systems testing (IST) and critical load testing
- Identify and resolve conflicts between test procedures, engineering deliverables, and equipment submittals

### Project Coordination & Reporting
- Track and report commissioning progress against project milestones, including shell & core readiness, critical path mechanical and electrical completions, and white space readiness
- Maintain commissioning databases, test records, and punch lists in commissioning management platforms (e.g., Cx Alloy, ICAT, Procore)
- Coordinate with procurement and equipment expediting teams to align vendor FAT dates with construction and fit-out schedules
- Participate in commissioning readiness reviews, pre-TAB meetings, and critical power energization planning
- Support the development of Operations & Maintenance (O&M) documentation and system turnover packages
- Liaise with hyperscale, colocation, or enterprise end-users during witness testing and integrated system validation

- Working knowledge of Uptime Institute Tier classification methodology, TIA-942, ASHRAE TC 9.9, and NFPA 70/72/75/76
- Strong understanding of single-line diagrams, electrical distribution architecture, mechanical schematics, sequence of operations, and BMS/EPMS control logic
- Familiarity with data center metrics including PUE, redundancy configurations (N, N+1, 2N), and critical load testing protocols
