HomeMy WebLinkAboutFinal Engineer Report 09.02.2020Mr. Schwaller:
We provided a review of the existing framing and foundation for the subject home. We found that the
foundation was constructed to the approximãte depth as anticipated and used in the calculations. The
minor variance in depth should not räuce the effióiency of the insulation and should be placed at a depth
of 1'-4" below the top of the finished walkway.
The framing around the doorway was found to be as anticipated, with the exception that only one (1)
trimmer was found. The plans have been revised to show a 2x- vertical cleat adjacent to-the trimmer to
assist with the installation of the vertical steel angle. The cleat may be either a 2x4 or 2x6- Should the
contractor be able to secure the vertical angle from rotation using the existing framing, then the 2x-
vertical cleat maY be omitted.
Please do not hesitate to contact me should you have any questions.

OBSERVATION NOTES
Arrived on site in the PM to review the existing footing depth and framing around the garden level exterior door.
The foundation adjacent to and directly below the exterior door was excavated to expose the bottom of the footing. The
bottom of the footing was found to be approximately 1 5 to '16 inches below the proposed top of walk. The contractor
requestedclarificationonthedepthof therigidinsulation. TherigidinsulationshallbeinstalledperthedetailA/S-01 and
to a minimum depth of 16 inches. The perimeter subdrain can be moved away from the foundation to provide clearance
fortherigidinsulation. Disruptiontothetransferofin-situmoistureshouldbenegligibleasthearewillbecoveredwitha
concrete walk.
The framing around the door was found to be 2x6 trimmers attached to a 2x6 plate. A sounding of the area above the
plate indicates that there is blocking between the plate and the wall plates. An obstruction scope was utilized to check
for a header above the door but was access was blocked by the plate and the cavity was not viewable.
Based on the above it is likely that the support for the floor above is a single 2x6 plate with blocking below the wall
plates. As such it is recommended that the retrofit of the header proceed with the installation of the steel angle.
The contractor requested a wood alternative to the steel angle header. Given the possible loads and limited height there
is not a reasonable wood header alternative.

OBSERVATION NOTES CONTINUED
The contractor requested a wood alternative for the trimmers and header support, given the visible framing and without
removing significantly more drywall, it is unlikely that an additional king stud or trimmer could be installed. Rather
attaching a 2x vertical cleat to the existing trimmer and attaching the vertical steel angle is likely least disruptive
alternative.
