Building Commissioning

We make sure your building's systems perform the way they were designed to, from planning day one through final sign-off.

WHAT IS BUILDING COMMISSIONING

What Is Building Commissioning?

Building commissioning is how we make sure a building works the way it was designed to. Every system gets tested, verified, and confirmed against what the owner asked for. It's not a one-time inspection. It's an ongoing process that runs alongside the project, from early design through construction and final closeout.

At GSS, our commissioning team acts as an independent set of eyes on the project, documenting the results and standing behind them every step of the way. Our work supports the project team, gives the owner confidence in what they're getting, and helps the building run the way it should for years to come.

Owner's Project Requirements

We make sure every system meets the specific goals and needs the owner set out for the project.

Design Intent

Every system is checked against the vision the design team laid out for the project.

WHAT GSS PROVIDES

What GSS Provides

Our commissioning services cover the full process, all grounded in what the owner needs and what the design team intended. Every step is documented, coordinated with the project team, and handled consistently from start to finish.

Commissioning Planning & Coordination

GSS builds and manages the commissioning plan, setting the scope, and responsibilities for every activity throughout the project.

Design & Submittal Reviews

Design documents and contractor submittals are reviewed as part of the process, making sure everything lines up with the owner's requirements and the design team's intent.

Pre-Functional Verification

GSS prepares and runs pre-functional checklists to provide a process for the contractor to confirm systems and equipment are installed correctly and ready for functional testing.

Functional Performance Testing

Building systems go through functional performance testing to confirm they operate as intended under real-world conditions, with results documented against the owner's requirements.

Systems Performance Verification

GSS independently confirms that building systems are installed, tested, and performing the way the owner and design team intended.

Retro-Commissioning

For buildings that were never previously commissioned, we assess how existing systems are performing, identify deficiencies that developed over time, and confirm equipment works as it should for the building's current use.

Re-Commissioning

When a previously commissioned building needs a second look, whether from a change in use, an equipment upgrade, or an operational issue, GSS identifies deficiencies, makes adjustments, and confirms performance meets the updated requirements.

Ongoing Commissioning

Our work doesn't stop at occupancy. GSS can continue verifying system performance long-term, keeping buildings aligned with evolving owner requirements as conditions change.

Testing & Balancing Report Review

We review testing and balancing reports to confirm air and water systems are balanced to design conditions.

Owner Training Coordination

GSS coordinates training for facility operations staff so they know how to run and maintain the systems we've commissioned.

Commissioning Issues Tracking

Every issue gets documented and tracked, giving you a clear record of deficiencies found and how they were resolved.

Final Commissioning Documentation

GSS wraps up each project with final documentation summarizing everything: activities completed, test results, and verified system performance.

THE COMMISSIONING PROCESS

The Commissioning Process

Building commissioning follows a clear, structured sequence, coordinated with your project schedule and adapted to fit the scope of each job.

01

Planning & Coordination

We kick things off by defining the commissioning process, pinning down project requirements, and assigning responsibilities across the team.

02

Design & Submittal Review

We review design documents and contractor submittals to make sure everything aligns with the owner's requirements and the design team's intent.

03

Pre-Functional Verification

Pre-functional checklists confirm systems and equipment are installed correctly and ready for functional testing.

04

Functional Performance Testing

We test building systems to confirm they operate as intended, under the conditions the owner and design team planned for.

05

Issue Tracking & Resolution

Any issues or deficiencies we find get documented and tracked until the responsible party resolves them.

06

Final Documentation

We wrap up with final documentation that records everything we did and confirms how the systems perform.

WHY COMMISSIONING MATTERS

Why Commissioning Matters

When building systems aren't properly checked, things get missed. Problems go unresolved, deficiencies slip through, and systems end up falling short of what the owner actually needed. Commissioning gives you an independent, documented process that checks installation, tests performance, catches deficiencies early, and confirms everything matches the owner's requirements and the design intent before anyone moves in.

Confirms systems are installed correctly
Checks that performance matches design intent
Catches deficiencies before they turn into real problems
Gives the owner a documented record of system performance
Helps the project team resolve issues before occupancy
Aligns building systems with the owner's project requirements
PROJECT APPLICATIONS

Project Applications

GSS provides commissioning services across a range of project types, adapting the scope and timing to fit what each project needs.

New construction building — commissioning services

New Construction & Renovation

For new construction and renovation projects, we confirm building systems perform as intended through design review, installation checks, functional performance testing, and final documentation, giving the owner a clear, documented record that all systems work as required.

Existing building — retro-commissioning services

Retro-Commissioning

For buildings that were never previously commissioned, we assess how existing systems are performing, identify deficiencies that developed over time, and confirm equipment works as it should for the building's current use.

Building reassessment — re-commissioning services

Re-Commissioning

For buildings that were previously commissioned but now need a second look, whether from a change in use, equipment upgrades, or operational issues, GSS identifies deficiencies, makes the necessary adjustments, and confirms performance meets the updated requirements.
