CG Project No.: 24296.10
Project Description
Rotted wood framing was recently discovered at an existing condominium. The wood framed
building consists of two stories above tuck -under parking. Rot was discovered in the sill plate,
sheathing, and glulam beam supporting a bearing wall and floor joists. We will provide a design
to repair the damaged framing. The proposed repairs involve additional framing added to the
sides of the existing beam. The rest of the rotted framing will be removed and replaced with
like kind. Our design will include areas where the framing was observable during our initial site
visit.
Scope of Work
We will provide stamped structural calculations in accordance with the current building code.

• Bolt bending yield strength of 45,000 psi is assumed.
• The Adjusted ASD Capacity is only applicable for bolts with adequate end distance,
edge distance and spacing per NDS chapter 11.
• ASTM A36 Steel is assumed for steel side members 1/4 in. thick, and ASTM A653
Grade 33 Steel is assumed for steel side members less than 1/4 in. thick.
While every effort has been made to insure the accuracy of the information presented, and
special effort has been made to assure that the information reflects the state-of-the-art,
neither the American Wood Council nor its members assume any responsibility for any
particular design prepared from this on-line Connection Calculator. Those using this on-line
Connection Calculator assume all liability from its use.
The Connection Calculator was designed and created by Cameron Knudson, Michael
Dodson and David Pollock at Washington State University. Support for development of the
Connection Calculator was provided by American Wood Council.
