Gentlemen:
This is a Fire and Life Safety Plan Review and is based on the
1988 editions of the Fire and Life Safety Code (UBC),
Mechanical Fire and Life Safety Code (UMC), Uniform Fire Code
(UPC), and other local ordinances and regulations.
Plans are conditionally approved for installation of the 2,
two -hour walls subject to the following conditions:
In accordance with City of Tigard construction files, this
building is a Type III -N building. It is the understanding of
this Plans Examiner that two -hour walls are being added for
compliance with the Uniform Electrical Code to establish three
separate buildings. The Uniform Building Code does not
recognize two -hour area separation walls for Type III -N
buildings to create separate buildings. This building is of
such size (approximately 15,000 square feet) and fully
sprinklered that it can be reclassified as a Type V -N building
and be within allowable areas of the Uniform Building Code.
Therefore, if the owner, in writing, will agree to allow the
city and the fire district to reclassify the construction of
this building from a Type III -N to a Type V -N construction, the
two -hour walls will be acceptable as creating separate
buildings for Uniform Electrical Code application only. The
reason for limitation to the Uniform Electrical Code is that
construction and design of these 2, two -hour walls do not .
comply with total requirements of the Uniform Building Code,
but do comply with the intent of the Uniform Electrical Code

for creating separate buildings. It needs to be further
acknowledged that no electrical wiring, with exception of phone
cable, may pass through these two -hour walls. Great care
should be taken in the future that movement of these two -hour
walls will be highly restricted with the electrical
configuration that is presently being installed.
With consultation of county electrical inspectors, this
department would highly recommend that the new meters being
installed on the building be equipped with a master shut -off at
each meter on the outside of the building, and at each meter
location a sign be permanently placed on the building stating
that there are additional master control shut -offs located
along the outside west wall. To the best of my knowledge and
in accordance with the county electrical inspectors, this would
comply with the Uniform Electrical Code, therefore, not
requiring the building to be separated into separate buildings
by two -hour area separation walls, and leaving much more
flexibility in remodeling the building as tenants come and go
requiring additional or lesser space.
If I can be of any further assistance to you, please feel free
to contact me at 526 -2502.
Sincerely,
Gene Birchill
Deputy Fire Marshal
