RE: 7295 Elderberry St., Springfield Oregon, Survey of Retaining Walls
Dear Eric:
On January 25, 2001, I surveyed the eXisting rear and middle Concrete Masonry Umt (CMU)
foundation walls and the taller portIons of tne side eMU foundation walls by means of a
Schoenstadt GA-52 metal detector For the most pan, I obtained good signal strength with clear
variations indIcating presence of magnetic materials at certain locations
Based on our survey of the walls it appears that there 'is vertical stecllocated at 16" on center in
the rear and side walIs and at 21" on center in the middle wall This steel appeared to run the
entire height of the wall. In several locations where our survey indicated st,eel in the center of the
wall, tips of deformed steel bars were visible at cut-outs In the sill plate The visible bars were
both #4 and #5.
There also appeared to be horizontal steel every 32" in all walls surveyed 1 was unable to visually
identify the size of the horizontal steel without destroying the wall
According to our design, the rear wall reinforcing stcel should have been at least #4 bars @ 16"
o C vertically and #4 bars @ 32" 0 C. horizontal, The middle wall was to contain #4 bars @
32" a.c. vertically and horizontally
