Dear Kelly,

In response to a telephone request from Jeff Reed, I visited and observed a portion of the
residence at 622 Alwyne Rd., Carmel, Indiana at 9:30 AM on December 16, 2019.
Dwing the visit the homeowner, Steve the contractor, Jeff Reed of Carmel Kitchens and
you were present.
Steve indicated that the owner wished to remove a column near the door ro the garage
and a beam below the ceiling in the kitchen azea and replace them with framing above the
ceiling and in the attic to create an open space free from obstructions.
I was able to access the attic space through a pull down ladder in the gazage. T'he roof
framing is a ridge and rafter system with collar tie beams on altemate fiames. The ridge
beam is a 2x8, and the sloped rafters and ceiling support stringers are 2x6 members. The
frames are spaced at l6 inches on cerrters.
Installation of the new beam directly above the ceiling and spanning perpendiculaz to the
frames near the center of their span will require cutting the ceiling stringers, which
currently extend from e�cterior wall to exterior wall. These stringers and the collar tie
beams resist the outward thrust created with loads placed on the sloped roof rafters. The
cut stringers need to be tied together with a steel strap on the bottoms with naits on each
side of the new beam to restore the resistance to the thrust. In addition, new collar tie
beams should be added to any frames within the length of the new beam that do not
currently have ties to assist the cziling joists.
The sizing of the new main beams is to be performed by others and is not included in the
scope of my work.
The sketch below shows the required connectors and framing.
