MEMORANDUM
Date: June 19, 2007
To: Dan Nelson
City of Tigard Building Department
For: IBC Code Analysis
PacTrust Corporate Center
Buildings 16 and 17
Portland, OR 97224
To facilitate future tenant improvement construction work, we have decided to do a code analysis
for the two, three -story buildings in this park. This code analysis is to demonstrate how these
buildings, which were built under the UBC as a type II -1 Hr., will figure as an IBC type II -B.
Chapter 3 — Use and Occupancy Classification; the building will be figured as a B occupancy,
with subsidiary A -3 and S -2 uses. The A -3 by size and occupancy fits into the B group.
Chapter 4 — Special Detailed Requirements based on Use and Occupancy Classification —N /A
Chapter 5 — General Building Heights and Areas; per table 503 basic area for Type II -B, B
occupancy is 23,000 SF per floor, and four stores tall. Existing building is three -story with a lower
level floor plate of 16,222 SF and 22,879 SF for the upper two levels — totaling approximately
62,000 SF. 22,879 SF < 23,000 SF and three stories < four stories; allowing non - separated uses.
Chapter 6 —Types of Construction; Type II -B.
Chapter 7 — Fire - resistance Rated Construction; N/A due to type and proximity to other buildings
other than shaft (stair towers), which can be 1 -Hr. (in lieu of 2 -Hr.) due to being fully sprinklered.
Chapter 8 — Interior Finishes — N/A
Chapter 9 — Fire Protection Systems; fully spinklered up and down.
• Chapter 10 — Means of Egress, two required exit stair towers + non - required central stair which
opens between 1 and 2 and 2 and 3 when hold -opens close (triggered off of sprinkler system) —
this also encloses elevator lobby. Corridor can be non - rated, with smoke control and closers at
doorway penetrations because of fire sprinklers.
•
Chapter 11 — Accessibility; building complies as constructed.
Chapter 12 — 28; N/A
Chapter 29 — Minimum Plumbing Fixtures; 62,000/200 = 310 occupants / 2 = 155 occupants each
sex = 6 T + 3 L required. 11 T + 6 L (women), 5 T + 6 U + 6 L (men) provided. Pair accessible
DF each floor.
Chapter 30 — 34; N/A
