GDG provides testing services for System Integrators, Contractors, Facility Owners/Operators and various Government Agencies.  Each testing program and written report is customized to meet specific needs or written specification.  

Commissioning is broken into several phases over the course of an afternoon, a day or a week depending on the scale and scope of the project and consists of, basic functional testing, performance measurements (THD, S/N, STI and the like), final system tuning and report generation.

While we often commission our own projects, we are also brought in as an independent third party to verify and optimize performance of systems designed by others.  Proper commissioning, especially careful tuning, is often what is missing and required to take good system to great or a poor system to functional.
