Re: Proposed demolition of existing house and rebuild on existing foundation.
Dear Dexter:
I inspected the above property on January 7, 2009 to determine if the existing foundation and walls
can support a new structure after removing the existing residence. I also ceviewed the plans
provided by Autumn Design {dated 11l21/08). The existing construction of #he property is a single _
story wood framed house with masonry (concrete block) wall crawi space foundation. The existing
foundation is suitable for support of the new proposed two-story house. The new structure should -
have an interior beam line to support the main f[oor with the exterior waAs used to support the
second fioor and roof framing. The existing foundation walls should be repointed in areas where �
cracking has occurred and stair step cracking areas shall be reinforced with #5 dowels grouted into
vertical cores at the crack in the south-each corner and any other areas of stepping cracks of the
wall. Pfease provide the proposed plans (including floor and roof truss shop drawings) so I can size
the interior #ootings to minimize differential movemeni befinreen the new footings and existing
foundation.
The plans I reviewed from Autumn Design show new foundation for the porch on the west end of the
building. in this area there is a perimeter foundation wall in place. I# is my recommendation to use
the existing foundation and add interior footings as needed to support the floor instead o# providing -
new piers and footings as shown on the current plan.
Please feel free to share this letter with the iocal building official and builder as required. You may -
contact me at {320)259-6575 if you have any further questians or cvmments regarding this matter.
