This memorandum is in response to the structural plan check comments by Miller Consulting Engineers
for the City of Tigard. Since the plan check comments the building's structural system has changed
extensively, such that some comments may no longer apply. An entire new set of structural drawings and
calculations have been issued for your review. Please see below for a response to each numbered issue:
1. Pages containing calculations for the trash enclosure have been added to the package. The changes
have been forwarded to the architect so that they can be added to architectural sheet A1.2. In addition the
trash enclosure detail will be shown on the structural drawings as well.
2. We completed these calculations and the architect submitted them to the city with the rest of the
engineering calculations. They probably did not get forwarded to Miller Consulting. Please forward them
for review.
3. A note regarding the frequency of periodic special inspections has been added on sheet S1.1.
4. Veneer is 4" brick as called in the specifications. This allows standard veneer ties to be used per code
as described on S1.1.
5. A page has been added, showing calculations for the self - drilling screws at the exterior walls.
6. The calculations have been revised to show a "d" of 9.5 ".
7. Details have been updated to show a connection between the studs and the track.
8. The calculations have been revised to show a 2" of cover on the toe side and 3" of cover on the soil
side. Details have been revised to show the new wall changes.
9. Calculations have been update for the connection shown in the details.
10. Details have been updated to show the connections between the studs and the track as well as the
connection between the track and the HSS header.
11. Detail has been added to the plans. This detail shows the connection of the floor beam to the
concrete column. Please note that this particular beam is not part of a moment frame. The moment
frame lateral system has been changed to a different braced frame system.
12. Calculation pages have been added which show the mass of the veneer as an included weight in the
seismic calculations. The veneer is treated as a line Toad around the perimeter of the building.
13. Calculation pages have been added to the package showing the connection of the beams to the
columns. Three beams had to be increased in size to allow for the proper number of bolts at the
connections.
14. The detail has been updated to reference the correct detail.
15. Calculation pages have been added that show the method used for transferring load around the large
opening.
16. The moment frame system has been changed to a braced frame system. The drag strut
requirements have changed and are covered in the new calculation package.
17. New braced frame system instead of original moment frame system.
18. Calculation pages have been added to the package showing the uplift condition and checking for
lateral bucking.
19. Details have been updated to show a weld connection between the angle and the HSS.
20. Special inspection testing laboratory will submit reports for the inspected items for review. A final
approval letter will be provided.
21. We will provide structural observation for the listed items throughout the duration of the project.
22. This is a deferred submittal and will be presented prior to construction.
23. This is a deferred submittal and will be presented prior to construction.
24. This is a deferred submittal and will be presented prior to construction.
25. This is a deferred submittal and will be presented prior to construction.
26. This is a deferred submittal and will be presented prior to construction.
27. The proper sets will be presented to the city.
These comments should answer the questions that were listed. If you have further questions or require
more information please call.
