P11,261:fr(4.,?9/71 RE: Framing Issues Review, 9 Oak Hill Ln, S. Yarmouth
rr9' 4A At ...d'.1.04 Dear Mr. Grylls,
McKenzie Engineering Consultants, Inc completed review and design for the Mass
Checklist wind requirements for the house located at 9 Oak Hill Lane in South
$!,e'7,11;11'"'
, Yarmouth. We stamped redlined checklist requirements on the plans and provided
--,e,,,, d'
V '-',fr'f,', ,r,, checklist notes and details for construction.
..)„,„, .,,‘, ,, -,..),
During early June,we completed a site visit to review the visible framing and wind
resistive construction elements. Additional we reviewed two items that were recently
,',T ,' /;',-/ ; ',. identified during the town framing inspection.

Item 1: We reviewed the screws used to connect the joist hangers in lieu of the typical
,',,,°-.4',,,V ' ',1,4 nails used. Based on the review of the screw's manufacturers information,the screws
'. .:!!,,,..,, . ' . , ., ,
provide greater shear and pullout strength than the typical nails and are adequate for
use.
,
Item 2: Ledgerlok screws are required to connect the deck ledger to the rim board.
Since other screws that do not provide the same connection value were originally used,
to supplement these, the contractor will add one ledgerlok screw per 16"on center to
the ledger/rimboard connection.
.
If there are any questions on this matter, feel free to contact me at ipy-40,me.
Sincerely,
