DESCRIPTION OF STRUCTURAL SYSTEM
•
As a part of a Petco tenant improvement, (4) new HVAC Units are being installed on the
rooftop of the existing facility located at 15660 SW Pacific Highway in Tigard, OR. (3) of
the units are replacing existing units, and the other unit is new. Per the framing plans,
the units will require additional support framing as noted.
This package includes calculations verifying the adequacy of the existing roof structure
to accommodate the replacement and new HVAC units. Calculations and details for the
anchorage of the units to resist and seismic forces are also included.
