Project Name: Providence Health Care Clinic - Rooftop HVAC Units
From: Larry Oeth U5o
This FAX is to confirm that the building was designed for two units on the roof, each
weighing 10,800lb. We have received manufacturer's cut sheets indicating Intellipak F
Style units will be used, each weighing 7,840lb. This is lower than our design assumption
and thus the framing, as designed, is adequate to carry the units' weight.
The units will be mounted on factory curbs with aircraft cable tie -downs through bolted in
curb fillers per manufacturer's specifications.
Please call if you have any questions regarding the above.
