In this episode Mark, Clay, and Nick discuss two critical parts of the commissioning process....pre-functional and functional testing. This as the episode title says is where the rubber meets the road. We dive into what each is, how to conduct each, what to include in each, and much more. Our subject matter experts Mark and Nick give their personal opinions and outline how they believe the process should go in these stages of commissioning.
