BULLETIN
Date: August 10, 2022 Number: CT-05 Project#: 21078
Project Name: South River Terrace Attached: CT-05.1
Subject: SOG Dowels to Cantilever Retaining Wall
Drawings Affected:
Description/Action:
This bulletin provides response to RFI's, design clarifications and/or variation requests for the
'South River Terrace' project located in Tigard, Oregon.
Per our discussion with Taylor Morrison, it's our understanding that we will need to provide a rebar
dowel connection for the slab-on-grade to the existing cantilever retaining wall in place of the #3
bars @ 24"o.c. shown at the top of the retaining wall per Bulletin CT-02 (06/20/2022).
See attached page CT-05.1 for the dowel connection. Note that this slab-on-grade dowel
connection may also apply to adjacent foundation walls.

Site Visit Requested By: Rob (Taylor Morrison) Met With (on site): Rob (Taylor Morrison)
Purpose: Evaluate lot subgrade
Outstanding Issues:
Lot subgrade
I arrived on site and met with Rob(Taylor Morrison) to observe the subgrade for building 20. I observed lot subgrade
to consist of brown silt with some areas covered by approximately 2-3 inches of%"-0 crushed rock. I used a Y2"
diameter steel probe to evaluate the consistency of the subgrade and based on penetration resistance, the subgrade
observed today generally appeared to be stiff to very stiff.
Conclusion
Based on our observations, it is our opinion that the building subgrade observed today as indicated on the
attached site plan, have been prepared in general accordance with the project plans and our geotechnical
recommendations.
