BULLETIN
Date: July 7, 2016 Number:CT-O8 Project#: 15238
Project Name: River Terrace Attached: CT-08.1
Subject: Concrete Stem Wall Height
Drawings Affected:
Description/Action:
This bulletin provides response to RFI, design clarifications and/or variation requests for the 'River
Terrace' project located in Tigard, Oregon.
It's our understanding that there are some site conditions which require the concrete stem wall to
exceed 4'-0" in height. This is an acceptable revision for stem walls up to 8'-0" in height provided
the differential height between exterior finish grade and the soil elevation in the crawlspace does not
exceed 2'-0" as shown in the attached detail. Note that either finish grade or crawlspace soil
elevation may be at a higher elevation as long as the differential height between the two is not
greater than 2'-0".
