Does anyone have experience complying with this requirement? The reference guide does not offer many details on how this aught to be achieved. Can it be done in-house? Would most mechanical/TAB firms be capable of performing this service?

This is a little sticky. First, I'd develop a PM plan for your BAS that includes the sensor calibration and make sure that the phasing of this calibration aligns with the manufacturer's recommended interval.
Then you have a couple of options for actual calibration:
One, you could hire your BAS vendor or one of their certified contractors to complete the calibration. This service is sometimes included as a part of the overall BAS contract. I think this would be the most direct route.
Your other option is to do it in-house but your methodology would have to follow that listed in the manufacturer's product specifications. It may require some additional instrumentation.
In either case, you're going to have to submit a calibration report that summarizes the calibration and system testing performed during the performance period and within the manufacturer recommended interval.
Hope this helps.

Thanks for your detailed reply. I'm currently interacting with the client's controls/mechanical contractor to define the scope of work. Your suggestions will help.

I have also found that the preventative maintenance contractor is not always sure how to do this, as some of the equipment does not have a calibration schedule (valves, dampers, temperature sensors) from the manufacturer. In their words, "either it's working, or it needs to be replaced". My guess in these cases is that the equipment is verified or replaced.
Has anyone had this type of issue? How have you resolved it?

Our current (not submitted yet) strategy is to use the EPA's recommended interval of 1 year... We also cannot acquire anything official from the manufacturer...if anyone else has tried the EPA route, we would love to know what the outcome was...
