RE: Safeway Store #383, Tigard, Oregon
New Cooling Unit
MCE Project No. 980041
Dear Mr. Jefferis:
At your request, Rob Aman of Miller Consulting Engineers, Inc. performed a visual
structural site observation of the subject project. The purpose of this site visit was to
observe any structural deficiencies at the location for the new cooling unit.
Per a phone conversation between Mr. Aman and Mr. Jefferis, the new cooling unit will
replace the existing cooling unit, and will be placed precisely at the same location. The
existing cooling unit is located on a structural concrete slab at the second floor mezzanine
in the northeast corner of the store.
Per information provided by you, the new cooling unit operating weight of 4600 pounds
is less than that of the existing cooling unit weight of 5050 pounds. In addition, the new
and existing cooling units have essentially the same overall dimensions. Based on this
information, the existing structural slab will be adequate to support the new cooling unit.
However, the new cooling unit will require anchorage to the structural slab for seismic
loading requirements. See the attached calculations and detail sheet for anchorage
specifications.
If you have any questions regarding these issues please call me.
Respectfully,
