CERTIFICATION FOR AS-BUILT CEILING JOISTS
Northampton Building Department:
It was requested by Bob Walker, of Construct Associates, the contractor for the subject
residences' garage renovation, that I provide a certification letter confirming that the as built
ceiling joists in the garage are acceptable. Following a site visit to the residence on Monday,
December 16,2019 by Tara Strassburg of SSB Engineering,we analyzed the existing condition and
have developed the following repair plan:
1- Provide 2x4 SPF#2 collar ties @16" O.C., a minimum 2'-0" long,centered on the ridge.
2- Provide vertical 2x4 SPF #2 members at every 2x8 ceiling joist lap location. Provide (2)
Timberlocks at the top and (2)Timberlocks at the bottom of each 2x4.
3- Provide (2) additional Timberlock screws to each 32" lap, so there will be 4 Timberlocks
total per lap splice, at each 2x8 ceiling joist.
4- Provide 2x4 knee-walls on each side of the attic area, a minimum of 2'-6" away from the
edge for rafter support. These should be nailed to each rafter and placed on a bottom
plate bearing on the attic joists.
Attached is a sketch outlining these repairs. This approval/recommendation is for the
components of the structure outlined above,and no other members/components in the garage's
structural system have been inspected or approved by SSB Engineering, LLC at this time. Please
let me know if you have any questions or require any further detail. I can be reached at (617)
676-7480 or jesse@ssbengineering.com.
