Dry Rot Investigation for a Condominium Complex in
Lake Oswego, OR
This condominium complex consists of ninety-six units
and was constructed in the late 1970's to the early 1980's; forty-eight units
are upper floor units and forty-eight are lower floor units. At the
time Ogren Engineering was hired, the homeowner's association
was concerned if there was any dry rot damage, and if so, how much.
Working closely with a building moisture expert, we were able to prove there
was extensive dry rot, even in locations not originally considered by
the homeowner's association.
Our investigation proved to be
essential to the safety of all occupants as we discovered damage in the
stairs providing access to nearly all upper floor units, the landings at the
top of those stairs and the privacy fences surrounding the ground floor
patios.
Often, dry rot is difficult to
detect by simply looking at a structure. However the
team assembled by Ogren Engineering for this project has years of expertise
in this field.

For
example, the wall pictured above when covered with siding appeared as
if it had no
problems. Upon further inspection of the inside of the wall, there is
evidence of mold and dry rot which can lead to structural failure. Because these stairs are the only access to the upper floor units, failure
of these stairs would be devastating.

The
privacy fences surrounding the ground floor patios seemed fine to the
untrained eye, however here is evidence of total destruction due to dry rot.
Ogren Engineering was able to demonstrate this issue to the homeowner's
association so they could take preventative steps to keep the dry rot and
decay from spreading into the main portion of the buildings.

Here we can see a framer's nail
puller driven into the main support beam of a second floor entry balcony.
There is also evidence of a prior repair that did nothing to solve the
problems this balcony had. Because of our investigation, the owners of
this unit were able to rebuild their entry balcony before a catastrophic
failure occurred.
