Re: Progressive Insurance Remodel
Dear Dave:
As requested, we have completed structural calculations and drawings for the Progressive Insurance
Remodel in Tigard, Oregon. The attached calculations L -1 through L -14 and G -1 through G -6, and
drawings S -1 through S -5, were based on the requirements of the 1994 Uniform Building Code.
The structural work to be done in this remodel consists of removal and modification of several
existing interior bearing walls and shear walls. We have replaced the removed existing structural
walls with steel moment frames and wood shear walls in an effort to minimize the impact to the roof
diaphragms and exterior shear walls, and to match the original load paths. New elements and
modifications to existing lateral resisting elements were based on zone 3 seismic and 80 mph
exposure B wind load as per the 1994 Uniform Building Code.
Please call if you have any questions or require additional information.
Sincerely,
C
Eric R. Sutter, P.E., S.E.
