Construction Revisions to Columns at Main Floor
During a construction inspection for a single-family residential remodel project located at 19726 8e Ave W in
Edmonds, the framing inspector observed that two (2) columns located at the main floor were not installed in
accordance with the structural drawings. At the west wall in the gym area, a (3) 2x6 column was installed in lieu of a 6x6
column (see Photo 1). At the north wall within the bedroom, a (4) 2x6 column was installed in lieu of a 6x6 column (see
Photo 2). Both columns were installed with (2) 2x members below the header and the remaining studs were installed
full height to the underside of the top plate. We have reviewed the column loading against the as -built conditions and
have determined that the columns are acceptable as installed. No upgrades will be required. Please refer to sheet SS-1
for the revised column sizes and locations.
