The intent of Commissioning is to verify that the project’s energy-related systems are installed, calibrated and perform as intended.

Neudorfer Engineers LLC, an Integra Company (NEI), provides a collaborative approach to commissioning project management. Our staff coordinates labor & logistics with each project team to maintain each project’s deliverables. We apply this perspective to all commissioning activities so our clients may reap the benefits of the commissioning process. We take pride in our ability to assist our valued team members achieve a quality product on time and under budget.

Our commissioning team includes professional engineers and field engineering technicians with extensive experience in operations and maintenance and building automation systems. We are able to provide an Owner a complete building commissioning project that is economical for all types and sizes of buildings, and the varied types of building systems. 

Neudorfer Engineers offers the best services at the most competitive cost possible. Our 52 years of experience and hands-on knowledge of building systems gives us an advantage that we leverage into our commissioning approach.

We lead the Commissioning efforts from project inception to project closeout to assure that the commissioned systems function together properly to meet the owner’s performance requirements and the design intent in a composite manner. Our team works closely with architects, engineers, general contractor, consultants, subcontractors, Owners representatives, building maintenance, & end users to ensure that commissioning processes & activities are integrated into construction schedules. Our team provides technical assistance to the design and construction teams to identify issues, evaluate solutions. We incorporate the cumulative knowledge of the project team into a coherent training and knowledge transfer process during the turnover period.

Neudorfer Engineers’ team is a resource for validating operating strategies.  Our ability to understand design intent and convert that intent to a clear and effective operating strategy to provide the Owner with a quality product. NEI adheres to the requirements of NEBB Commissioning Procedures, which follows the ASHRAE Guideline 1 for the HVAC Commissioning Process. NEI assists in developing the commissioning specifications that detail specific requirements for commissioning. Through peer design reviews and submittal reviews, NEI ensures that the Owners Project Requirements (OPR) are incorporated into the design and installation.

During the various design phases, plan review for various aspects of the design which affect the installed systems functionality, the constructability of the proposed system, the sizing of equipment, the Sequence of Operation of the equipment, validation or certification issues, & recommend additional energy-saving features for incorporation into the design. These services include HVAC systems, Building Envelope systems, Process Industrial systems, Fire Alarm & Life Safety systems, Electrical systems.

During the construction phase, perform field inspection to ensure the mechanical and electrical systems are installed correctly and are field tested per the design documents. These services include Commissioning Project Management, Factory Acceptance Testing, System Installation Inspections, Startup, Troubleshooting, Technical Commissioning, Scheduling, Training, FDA Validation, ISO Certification, and O&M manuals. Neudorfer Engineers is trained in current good manufacturing & laboratory processes (cGMP & cGLP).


Complex projects require comprehensive control. Therefore, identification and resolution of issues as early as possible delivers the most cost effective and operationally effective project solutions. Neudorfer’s integrated and strategic approach to commissioning keeps the entire project team aware of potential and real schedule changes, minimizing the impact on construction schedule and project turnover.

Through building envelope commissioning, NEI assures that the project’s building envelope system adheres to Washington state energy code (WSEC), ASHRAE 0-2005, & the National Institute of Building Sciences (NIBS) Guideline 3-2012 requirements. Commissioning of the building envelope assures that the exterior wall system is tight, allowing for optimal energy efficiency of the HVAC systems.

NEI performs & leads 10-Month Reviews, as required by LEED Enhanced Commissioning credit. Prior to project substantial completion, NEI schedules the 10-Month Review and assigns responsibilities. NEI notifies the project team of the 10-Month Review requirements so that the team members will be prepared. NEI will provide an interview questionnaire to the Owner’s building manager at substantial completion and again 1 month prior to the 10-Month Review. This allows the team to discover problematic equipment/systems ahead of time, and if additional training and/or repairs are required.
