By integrating modern tools and maintaining strong client relationships, CRA continues to lead the industry in creating high-performing, mission-critical facilities.

Why CRA Adopted Bluerithm

For years, CRA relied on traditional tools like Excel spreadsheets to manage commissioning tasks. However, as projects grew in scale and complexity, this method no longer sufficed.

According to Commissioning Operations Manager Jedediah Moore, adopting Bluerithm was a natural evolution: “As the industry shifted, software solutions like Bluerithm emerged to streamline processes and offer better visibility. We didn’t have a single ‘aha’ moment—it was just the logical step forward.”

The introduction to Bluerithm came through a professional connection between CRA’s Josh Harwood and Bluerithm founder Andrew Martin. What began as a conversation at an industry event evolved into a long-standing partnership, with CRA among Bluerithm’s earliest adopters.

The Lutheran Hospital Project

Scope and Scale

Lutheran Hospital was a complete replacement hospital project involving an extensive and tightly managed commissioning scope. The hospital incorporated:

Hundreds of checklists and forms, including FPTs (Functional Performance Tests)
Hundreds of air handling units, exhaust fans, and VAVs (Variable Air Volume boxes)
A pioneering implementation of NFPA 4 integrated fire alarm system testing

Notably, this was the first hospital project in Colorado to utilize NFPA 4 standards, with CRA establishing the procedural template in Bluerithm for future healthcare commissioning across the state.

Innovations and Firsts: NFPA 4 Testing

NFPA 4 mandates the integrated testing of fire protection and life safety systems to ensure they function as intended in emergencies. This was the first time such testing had been implemented in Colorado for a healthcare facility. CRA used Bluerithm to develop and execute the entire suite of NFPA 4 test scripts. The Colorado state regulators not only reviewed but formally accepted the system after successful completion.

This testing methodology has since become a benchmark across other healthcare facilities in the region, demonstrating how one project can influence an entire sector.

Brief Overview of NFPA 4

NFPA 4, or the National Fire Protection Association Standard for Integrated Fire Protection and Life Safety System Testing, is a U.S. standard that outlines the requirements for testing the performance of multiple interconnected fire protection and life safety systems as a single integrated system.

Key Points About NFPA 4:

Purpose

NFPA 4 ensures that when a building has multiple fire and life safety systems—such as fire alarms, sprinklers, emergency lighting, smoke control systems, and fire doors—they all work together as a cohesive unit in real-world emergency scenarios.

Integrated Testing

Unlike traditional testing that evaluates systems individually, NFPA 4 focuses on integrated system testing, confirming that all interconnected components communicate and respond correctly under emergency conditions. For example, when a fire alarm is triggered:

Smoke control fans should activate,
Fire doors should close,
Emergency lights should turn on,
Elevators should be recalled to designated floors,
And all these actions should happen in the correct sequence and timeframe.

Critical for Hospitals and Complex Buildings

NFPA 4 is particularly important for healthcare facilities, high-rise buildings, airports, and large institutional campuses, where systems are highly complex and lives depend on multiple safeguards functioning together.

Commissioning Implications

Implementing NFPA 4 requires:

Detailed planning,
Test scripts and documentation,
Collaboration between multiple contractors and system vendors,
And compliance with AHJs (Authorities Having Jurisdiction).

How Bluerithm Was Used

Daily Usage and Internal Collaboration

According to Anthony Williams, Commissioning Project Manager, Bluerithm became the backbone of daily operations:

Checklists and Issues

Every issue observed in the field was logged in Bluerithm. Contractors were assigned tasks directly in the system, which the entire team—including owners—could view in real time.

Transparency and Accountability

Visibility of issues held contractors accountable, ensuring pre-functional checklists were completed and flagged when not.

Internal Workflow

Commissioning technicians used Bluerithm to draft and revise performance tests. Supervisors reviewed them through the platform’s internal quality control tools.

Batch Processing and Scaling

Given the size of the project—over 700 VAVs tested, among other components—CRA leaned heavily on Bluerithm’s batch editing features.

“If something changed late in the game, we didn’t have to revise every checklist manually. We could apply updates across hundreds of tests in one go,” explained Moore.

Reporting and Client Interaction

Though owners rarely logged into the system directly, they consistently received detailed, customized reports generated through Bluerithm. These reports offered a high-level summary while ensuring no detail was lost. The ease of producing and tailoring these reports made client communication smooth, clear, and professional.

Moreover, other stakeholders—including contractors and vendors—interacted with the system by uploading photos, responding to issues, and coordinating resolutions efficiently.

Challenges of Hospital Commissioning

Hospital commissioning is uniquely challenging due to the intricacy and interdependency of systems. Moore outlined several key complexities faced during the Lutheran project:

Fire Safety: Hospitals follow a “defend-in-place” strategy rather than evacuation. This requires extremely robust integration between fire detection, ventilation, alarms, and mechanical shutdown systems.
Redundancy Requirements: HVAC and power systems must function even if a component fails. This redundancy adds layers of complexity to design and testing.
Humidity and Pressurization: Operating rooms and sterile spaces demand precise control of air quality, humidity, and pressure.
Compressed Schedules: Patients were moved into the hospital while CRA was still commissioning systems. This overlap compressed testing windows and required real-time problem solving.
Continued Support: Post-occupancy, CRA remained engaged for up to a year to address issues as they arose, maintaining documentation and tracking progress in Bluerithm throughout the warranty period.
