Project No. 22105.01
Project Description
Sidesway Engineering was retained by the Edmonds Park Townhomes HOA to perform analysis and design
as necessary to obtain a building permit for the repair of an exterior beam that supports a single unit's
exterior deck and an architectural trellis at the 2nd floor of the existing townhomes located at 610 Daley
Street in Edmonds.
The beam does not support any load from the roof or floors above, just the single unit's exterior deck.
The beam extends approximately 10' beyond the deck supporting a trellis. This portion of the beam is
wrapped in siding however moisture penetration has become a problem causing dry rot and beam sag.
For economics, it was decided to add a single post and footing at the edge of the deck so that the portion
of the beam supporting load is adequately supported in lieu of replacing the entire 18' long beam. The
post lands in a landscaped area between garage doors. The remaining beam length at the trellis will
remain in place, however the contractor will locate the source of the leak and seal the beam to prevent
future moisture penetration.
The original construction documents of the building were provided to us for use.
Scope of Work
Provide gravity calculations for the beam repair as required to obtain a building permit. Provide framing
plans and details as necessary for permit issuance. The lateral system of the structure is not changing
therefore a lateral analysis was excluded from our scope of work.
Design Criteria
2018 International Building Code (IBC)
2018 International Existing Building Code (IEBC)
ASCE 7-16 Minimum Design Loads for Buildings and Other Structures
Applicable Material Reference Standards (ACI, AISC, NDS)
This is a Risk Category II structure designed for the following loads:
Dead Loads: 15psf (roof/floor)
Live Loads: 25psf (snow)
40psf (residential)
60psf (deck/balcony)
Project Summary
The proposed beam repair as designed in the following calculations conforms to the 2018 IBC and IEBC.
Refer to the construction drawings for structural framing requirements.
Disclaimer
This calculation package is based on the documentation that was available to us. Sidesway Engineering
did not perform an as -built to verify the accuracy of the provided data and we should be contacted if there
are any discrepancies with the assumptions contained within these calculations. We assume the structure
has no known deterioration or unknown damage that would adversely affect capacity.
