RE: Roof at 3400 South College Avenue
Dear Sharon:
January 14, 1998
I have been requested by Francisco Galvan to analyze the adequacy of the roof structure for
carrying new mechanical units, for the proposed Las Margaritas restaurant.
I
I have spoken by phone with Gene, the mechanical designer, and he has provided me with the
weights and dimensions of the proposed roof -top units. The duct furnace, 41-1/4" x 26",
weighing 286 pounds, is equivalent to a 38 psf load. The evaporative cooler, 39-1/2" square,
weighing less than 200 pounds, is equivalent to less than 18 psf.
i
This morning I went to the site of the proposed restaurant, met with Francisco, and he showed
me the location where the new mechanical units would be installed. I walked on the roof
myself, and observed where the existing ductwork through the parapet wall would be
abandoned to provide a space for the new ductwork from the new units. Fortunately, the new
units do not necessitate creating a new roof penetration.
Based on the relatively low distributed load values, and my first-hand observation of the roof,
I consider that the roof is structurally adequate to carry the two proposed mechanical units.
Very truly yours,
J elle K. Rohrbai
