MEMORANDUM
To Whom it may concern Date October 21, 2014
Re Eric Williams Residence:
A Parcel Located East of New Castle (Section 35, Township 05, Range 90)
Garfield County, Co.
On October 18, 2014, at the request of Matt Van Hoose of Van Hoose, I performed a
framing inspection of the noted residence. At this time the residence is under construction
and all of the framing is exposed to view.
There are two (2) items of concern
1 The need to penetrate an LVL (Laminated Veneer Lumber) upper floor beam with a
plumbing waste line
2. The nailing pattern of the an LVL ridge beam.
The floor beam is question is a double -1.3/4" x 9.1/2" LVL. It spans approximately
16'-0" east -to -west, and is located above the north wall of the kitchen. Upper level floor
joists (9.1/2" `I' joists span 14'-6" and frame to the beam. The beam is supported at
multiple points along its length. An interior wood stud wall is framed beneath a 8'-O"
long section of the beam (the east end of the beam). The stud wall is framed as a bearing
wall and can successfully transfer loads to the main level floor framing, and ultimately, the
foundation.
The proposed plumbing penetration is to be a 3.1/2" diameter hole located approximately
5'-0" from the east end of the beam. The hole is to be drilled 3.3/4" from the bottom of
the beam so that 2" of beam material remains in place under the hole. This proposed
plumbing penetration is structurally acceptable.
The ridge beam supports roof trusses in the 25'-0" wide north wing of the residence. The
trusses are half trusses so that the span 12'-6" from the east and west exterior walls,
respectively to the center ridge. The trusses bear on top of the quadruple -1.3/4" x 18"
LVL ridge. Each lamination of the quadruple LVL is nailed to the adjacent lamination
with a vertical row of five (5)-16d (penny) nails at 12" on center. This nailing pattern is
structurally acceptable.

Entry Piers at Eric's
Hi Matt,
I got the soils report from H -P.
Everything is as we discussed: 8" diameter piers with 12" dia. bells.
Extend piers down to bear on undisturbed natural bearing soils.
Reinforce the piers with (2) - # 4 vertical.
