<FONT FACE="Times, Times New Roman"><SPAN STYLE='font-size:12.0px'>Question for the group (although I have a sense of the answer, but no back up):<BR>
<BR>
If an architect, engineer or licensed CBO (not associated with a municipality) is aware of a code violation due to permitted and approved modifications to a building, are they obligated to report it? And if so, to whom? Chapter and verse please.<BR>
<BR>
Here is the scenario:<BR>
For various reasons not critical to this discussion, the HVAC system of a multi-story time-share building was modified to improve the positive pressure and fresh air supply. This modification was permitted, we believe.<BR>
<BR>
The building has interior corridors. The conditioned , pressurized fresh air is supplied through the duct system of the central corridor, which in my mind, makes it a plenum.<BR>
Through the corridors, this pressurized air is intended to be forced into the units, pressurizing them as well.<BR>
<BR>
This configuration requires, I believe, modifications to the sensor and alarm system in the corridor ducts, including the elevator.<BR>
<BR>
As designed/installed, the pressurization of the corridor would also force air, and smoke, into the exist stairwells and elevator shaft, which are static (no pressurized, vented system for the stair wells).<BR>
<BR>
Being pressurized, with 100% fresh air, there is no return air for the corridors on each floor. No return air, no way to monitor smoke/fire in the system.<BR>
<BR>
If there is a fire, smoke in the corridors can be forced into the units, into the stairs, into the elevator shaft.<BR>
<BR>
Assuming these observations are correct, it would appear that in the process of improving the HVAC created a more critical life safety situation.<BR>
<BR>
Input please.<BR>
<BR>
Thank you.<BR>
