Each project has its own nuances and there is often a lot happening behind the scenes to ensure a favorable outcome. Through McIntosh Corporation’s mechanical commissioning services, commercial clients can rest easy knowing that their project will remain on track until construction is complete or the necessary equipment is installed. Our Tulsa mechanical commissioning engineers will keep you updated on progress throughout the lifespan of a project, ensure Factory Acceptance Testing (FAT), expertly install mechanical systems, and confirm functionality before leaving the jobsite.

McIntosh Corporation coordinates with our subcontractors and other trade contractors on the job to pre-check every part of mechanical systems as early as possible. Our Tulsa mechanical commissioning team makes sure that the entire system is fully operational and conforms to the client's needs before leaving the job site. This helps ensure complete satisfaction and limits the chances of return visits due to small problems that could have been overlooked initially. We also offer 3rd party (Fundamental and Enhanced) commissioning required by LEED for your building's USGBC certification.

  • Pre-Design Planning - Pre-design commissioning evaluates the process of developing quality standards.

  • Design Intent Development – Commissioning is used as a quality control process to establish and prioritize project-specific key success criteria, from which the design team will develop a project design. 

  • Design Review – Provides early quality control feedback to the Owner and the A/E design team. Provides an opportunity to make adjustments before there is a notable impact on the project. 

  • Commissioning Plan – Provides a project-specific overview for construction verification, documentation, and the functional testing process. 

  • Installation Verification – Evaluates the construction process to verify that the installation quality meets the project Design intent. Early feedback provides an opportunity to discover any deficiencies and make adjustments before the project is completed.

  • Functional Testing – Functional testing is a specific set of tests designed to verify that the constructed system meets the Project design intent. Individual components are started up and checked, and then the system is tested. An action item log is maintained to document any system adjustments.

  • Acceptance Testing & Final Report – Acceptance testing demonstrates that the completed system meets the Owner's project requirements. A final report is issued to document the accepted system.


  • Systems Manual - Develop a systems manual that provides future operating staff the information needed to understand and optimally operate the commissioned systems.

  • Verify Operator and Occupant Training- Verify that operation and maintenance personnel and occupants are correctly trained.

  • 10 Month Warranty Review - At the end of the construction phase, the commissioning authority returns to the building at the 10-month point to review its operation for warranty issues.
