RE- 625 Peterson Street - Framing Inspection
Larsen Structural Design Project No 2024
Mr McCartney,
DESOGHONG SMARTER STRUCTURES
B1605752
Per our email correspondence, you have communicated to me that there is a condition regarding
the bearing of a 2-Ply LVL valley beam at the northwest corner of the Unit A roof for the project
located at 625 Peterson Street The pictures that you have shared with me show the different plys
of the valley beam being supported partially by a steel shim pack and wood blocking The eastern
most ply of this valley beam does have not full bearing between the valley beam and the wall top
plate. This condition shall be fixed To remedy this condition, a solid wood block shall be inserted
between the bottom of the LVL valley beam and the wall top plate This blocking shall be attached
to the wall top plate with nails or wood screws
In addition to the solid blocking added below the LVL valley beam, an additional stud shall be
installed below the valley beam Currently there is a stud pack with three studs below this valley
beam The additional wall stud shall be added to the east side of the existing stud pack to have a
total of four studs supporting this valley beam
Please contact our office if you have any questions
Respectfully,

RE 625 Peterson Street - Site Observation Reportd
Larsen Structural Design Project No 2024
This site observation was made to review framing inspection items noted as discrepancy items by
the City of Fort Collins framing inspection.
The following items were reviewed while on site-
1 Unit A laundry room stud framing at exterior wall - The current framing at the north
exterior wall directly below the 3-Ply 91/2" LVL beam (Grid D.7 & E1) has two (2) studs
directly below the LVL within the exterior wall and a third stud with its long edge oriented
parallel to the plane of the wall At this condition, a single 2x stud shall be added to west
side of the existing two studs to make a total of (3) studs below the 91h" LVL The existing
stud oriented with its long edge parallel to the plane of the wall may remain in place and
does not have to be demolished See Photo #1 for the area noted above
2 Unit A - Level 1 Floor Framing - 4-Ply LVL beam (Grid E3) The required fastening of the
4-Ply LVL supporting the floor joists at the first level and shown in detail 4/S2 1 was
updated in ASI-7 and shall be attached as shown in this updated detail
3 Unit A - Roof Framing - South Dormer of west bedroom I reviewed the framing of the
girder trusses and truss framing for the south dormer at the Unit A Level 2 western most
bedroom The framing was structurally acceptable with regards to the wall studs framed
below the roof trusses and bearing on the 2-Ply LVL beams that transfer this load to the
exterior wall No additional studs are required above or below the LVL beams. See Photo
#2 for the area in question.
4 Unit A - Roof Framing - Valley Beam Support Condition I reviewed the support condition
of each of the 2-Ply LVL valley beams that are bearing at the exterior walls of Unit A. While
these beams do not have full bearing on the exterior wall, the bearing condition as
currently framed is structurally acceptable and no modifications are required See Photo
#3 for the framing condition at the NE valley beam to top plate connection.
5 Unit A - Level 2 - 6'-0" header at east wall (Grid G) As communicated to Mike McCartney
of Swift Builders in an email dated April 6, 2017, a minimum 2-Ply 7 1/4" LVL header with
(2) 2x4 trimmer studs and (3) 2x4 king studs are required
6 Unit A - Level 2 - West wall walk-in closet header. i reviewed the 3-Ply 2x10 header
installed for the window opening in the walk-in closet at the west wall of the second floor
of Unit A The 2-Ply 2x10 header is structurally acceptable

or destructive testing was performed, and we only reported on items readily visible or made
evident by surface characteristics. Unseen conditions may exist which could affect the
performance of the structure
