* As far as the firewall is concerned, this shows that there us much more to the job of an EC other than NEC compliance. In this case, the firewall was breached more than 36" above the finished floor which is a violation of the firewall requirements, including the insurance carrier through Factory Mutual. The penetration had to be removed, sealed and placed below the 36" mark to comply. This is a true firewall, not at fire rated partition, a free standing firewall.
Please show us this in writing. I challenge you to find anything in the UL Fire Resistance Directory that supports this and further more, this would mean all the mechanical systems would have to be installed at floor level. :roll:
Now, it seems you're already back tracking and adding info as the members challenge your statements so you should start over and add all pertinent information so we can all see what your actually complaining about.
If you are throwing local rules out there be sure to let us know.
