Is the build sequenced to prove readiness, or just to finish installation?

Rate each critical system and the commissioning process from 0 (absent) to 4 (embedded and verified). Facility readiness is gated by the weakest critical system, not the average: you cannot turn over a hall whose power or cooling is unproven. Installed-quality discipline is the separate Quality Scorecard.

Critical systems iReadiness is limited by the least-ready critical system (a bottleneck), not the average. One unproven system caps the whole facility.

Electrical / power chain

Mechanical / cooling

Controls & BMS / EPMS

Fire & life safety

Commissioning process

Cx plan & ownership iAn owner-approved commissioning plan with a named commissioning authority (CxA) and scope defined across all Cx levels before startup.

Test rigor (pre-functional + functional) iPre-functional checklists (PFCs) confirm each component is installed and statically complete; functional tests are scripted and witnessed, not run ad hoc during startup.

Integrated systems test iThe highest-level commissioning test (the integrated systems test in the data center Cx level model, within the Acceptance phase of ASHRAE Guideline 0 / BCxA). Includes pull-the-plug / black-building failure scenarios that prove the facility holds the critical load when a source fails.

Equipment is going in, but commissioning is trailing the schedule. Readiness depends on catch-up that energization pressure rarely allows.

Foundations

The disciplines, levels, and gates in this index draw on established commissioning practice:

ASHRAE Guideline 0 — The Commissioning Process
Building Commissioning Association (BCxA) — Best Practices in Building Commissioning
Data center commissioning levels — Level 1 factory witness through Level 5 integrated systems test
NETA Acceptance Testing Specifications (ATS) — electrical system acceptance
Uptime Institute Tier Standard — commissioning toward Tier certification
