Re: Framing Observation Report—Unit 245 and Unit 345 Decks (0315 s'E Cna )4'
Sunnyside Condos II

LEMN Project No: 11210351.001
Dear Ms. Mantel:
I would like to address the concerns that Julie Hultman brought to your attention in her email
from September 27,2022. Larson Engineering Inc. (LEI)performed a site observation on
October 11, 2022 to observe compliance with our updated plans signed on 9/15/2022,which
outlined the repairs to be completed to the decks attached to units 245 and 345. We observed the
following conditions:
1. The damaged columns supporting the unit 245 and 345 decks have been removed and
replaced (See photos 1 and 2).
2. Column caps identified in Section 1 of the new details were observed at all
columns (See Photo 3).
3. The concealed flange hangers outlined in Section 2 of the new details were also
observed (See Photo 4).
4. Deck floor framing was also observed to be replaced (See Photo 5).
5. Simpson H2.5A Hurricane ties were used to attach new deck joists to existing
new beams supporting the deck for Unit 245 (See Photo 6).
6. Damaged framing was observed on the east side of units 245 and 345 adjacent to
the fireplaces (See Photos 7 and 8).
7. Damaged framing adjacent to the fireplace wall of Unit 345 was removed and
replaced (See Photo 9).
8. New ledger was attached to the ends of existing floor trusses at 32" o.c. in some
locations and 16"o.c. in other locations (See Photos 10 and 11).
9. It is our understanding that 5" long Simpson SDWS Timber screws were used to
attach the new ledger to the ends of the existing floor trusses.
The attachment of the ledger to the existing floor trusses was analyzed by LEI and found
to be sufficient. Based on our site observations on October 11, 2022, it appears that the

repairs to the decks of units 245 and 345 were completed to our plans and specifications
identified on our plans signed on 9/15/2022.

this letter.
Sincerely,
