Principal Level Involvement
A principal of the firm is directly involved in every project we commission, from submittal review through witnessed testing. The engineers on your project are accountable for its result.
Expert Commissioning Services
Commissioning Mission Critical Facilities.
With precision, performance, and reliability.

Our Credentials.
ACG Member Firm
2N Mission Critical Corp is a listed member firm of the AABC Commissioning Group, the certifying body for independent commissioning authorities.
ACG US member directoryCxA Certified
2N Mission Critical's electrical principal is listed in the ACG directory as a Certified Commissioning Authority (CxA), the credential owner specifications commonly require of a commissioning provider.
ACG US member directoryIndependent of Design and Install
We are engaged by the owner and we install nothing. With no equipment line, no installation arm and no design fee involved, our verification carries no conflict of interest.
Every termination, every sequence, every failure mode, documented.
Why Choose 2N.
A commissioning authority is engaged to provide the owner with an independent, documented verification of the facility.
Independent of Design and Construction
As a commissioning authority engaged by the owner, we hold no equipment line, no installation arm and no design fee. Findings are reported without a conflict of interest.
Documented at Every Stage
Each phase produces a record: the commissioning plan, test scripts, issues log, results and the turnover documentation. The documentation is the deliverable.
Other 2N Services.
In addition to commissioning, we provide the studies and site roles that mission critical projects require, delivered by the same engineering team.
Design
Tailored to high-availability environments, from topology selection through construction documents.
QA / QC
An independent review carried out while the work is still accessible and still correctable.
Owner's Representative
A single party accountable to the owner, present on site and representing the owner’s interests throughout the project lifecycle.
Thermal Imaging
Inspection is performed under load, so a fault is found while it is still only heat.
Short Circuit Coordination Study
Establishes the available fault current throughout the system and confirms that equipment is rated to interrupt it safely.
Breaker Coordination Studies
Confirms selective coordination, so that a fault is cleared by the nearest upstream device and service to unaffected areas is maintained.
CFD Modeling
Run before the space is built, including the failure scenarios the room has to survive.

Everything running together, at load, with something deliberately going wrong.
Where Downtime Is
Not an Option.
Commissioning ensures continuous power, cooling and control, safeguarding operations where downtime is not an option.
Confidence From Day One
Commissioning confirms that systems meet design intent, industry standards and client requirements, delivering confidence and peak performance from day one.
Hidden Failures, Found Early
By thoroughly testing every component, commissioning identifies and corrects hidden failures before they impact critical infrastructure.
Risk, Driven Down
Mission critical commissioning minimizes operational and financial risk by validating that all systems function under real-world and worst-case conditions.
Hyperscale Data Centers
The primary focus of the practice.
Colocation Facilities
Multi-tenant critical environments.
Hospitals
Where continuous systems are life safety.
Call Centers
Continuous communication systems.
Stock Exchanges
Where an outage is measured in transactions.
Flight Control Towers
Continuous communication and computer systems.
Why Commissioning Matters
Published industry data is consistent year over year, and it points to the systems commissioning exists to verify.
54%
of operators said power was the primary cause of their most recent impactful data center outage, the single largest category.
Uptime Institute Global Data Center Survey 2024, n=97
80%
said that outage would have been preventable with better management, processes or configuration.
Uptime Institute Global Data Center Survey 2024, n=97
57%
said their most recent major outage cost more than $100,000. One in five said it cost more than $1 million.
Uptime Institute Annual Outage Analysis 2026, reporting the 2025 survey
Uptime Institute's 2026 analysis identifies UPS systems, transfer switches and generators as the dominant failure points. These are the systems we verify, under load, across the failure modes they are designed to withstand.
