Who We Are

SMI Commissioning & Consulting, LLC specializes in full-service commissioning services for building owners including; comprehensive design review, Commissioning Plan and specification development, HVAC equipment testing & evaluation, writing installation audit forms, system manuals and functional performance test procedures, and calibration & testing of existing building systems. We work as part of the team to get the Owner the building they want on schedule. Communication on the project is very important; therefore, we work with the Contractor to integrate the commissioning schedule into the master schedule and make continuous updates, we track and report any outstanding commissioning issues to ensure prompt resolution, and always aid in finding solutions to any issues that arise.

SMI Commissioning founder Nathaniel Mostajo has over 16 years of industry experience and has been providing outstanding commissioning services for over 11 years. SMI Commissioning was established in January 2012 by Nate Mostajo and Shanon Self with the goal of providing the level of leadership, project coordination support and problem solving services clients deserve from a superior Commissioning Authority.

Our firm has extensive experience commissioning a wide variety of facilities varying in complexity and size. Our project history includes mainly educational facilities for K-12 and higher education, laboratories and office buildings. SMI can provide either Commissioning Authority services, hired by the Owner or A&E Team as a direct representative, or Test Engineering services, directing and performing testing under the scope of the General Contractor. We have substantial experience with both Design Bid Build and GC/CM project delivery methods. In addition to our vast experience commissioning traditional mechanical HVAC systems, we have also worked on natural ventilation systems, displacement ventilation systems, energy management control systems, kitchen exhaust and ventilation systems, lab air and vacuum systems, water sourced heat-pump systems (both water to air & water to water), VRF fan coil systems, lighting control systems, architectural lighting systems, and access control systems.

SMI Commissioning has two owners/managers; Nate Mostajo (Commissioning Project Manager) and Shanon Self (Operations Manager). Nate started in the DDC controls industry working extensively with commissioning then transitioned into providing commissioning services building up a large network of satisfied clients. His in depth knowledge of MEP commissioning, DDC controls design, programming and loop tuning and lighting controls along with the enjoyment of his work regularly results in ‘word of mouth’ referrals for projects. (He has established a reputation of bringing cookies to Commissioning Meetings.)

After graduating from UW in 2007, Shanon opened a language/cultural consulting firm in Germany before returning to the USA to start SMI. She has over 10 years of project management, business organization and contracting experience. Currently, SMI has one full time employee; Michael Wilhelm (Commissioning Specialist). Michael has complete knowledge of HVAC and 30 years DDC Controls experience, much of which he worked closely with the Commissioning Authority on the project. He is a valuable asset to the SMI team.
