This week on HVAC 360, I share some of my lessons learned by review one of the most asked questions as a commissioning authority, "What is your number one issue?"  To that I have to say coordination, which is the topic of choice this week.  Not only do I go into why I feel this is the number one issue, but I also share some of my lessons learned from the field to help engineers produce a better set of documents.  If you like this episode please share with a friend or two.  Enjoy.
