Failure Review and Retrofit

The client initially hired an engineering firm to review the interior wall and determine whether the wall was bearing or not. The engineering firm reviewed the residence and deemed the interior wall to be non load bearing wall. The owner started removing the interior wall and immediately thereafter, the roof of the residence started to deflect significantly where the wall was removed. The client hired Kalkatic to review whether the wall was bearing or non load bearing and to come up with fixing the collapsed roof framing system. Upon reviewing the residence framing system, Kalkatic deemed the interior wall to be bearing as it was supporting the ceiling joists spanning from exterior wall to interior bearing wall. In addition, Kalkatic concluded that the ceiling joist was also acting as a tie joist to hold the stick frame roof trusses from thrusting outward.

After determining the cause of collapse, Kalkatic provided the client with drawings for design of interior beam, supporting column and foundation system.
