 The Vital Structure: 

CMU Wall Replacement Due to Vehicle Damage – Brockton, MA

Issue

 

Vital Structures was retained to perform a structural evaluation of the exterior CMU walls and wood roof framing after the west gable wall was struck by a vehicle.

Diagnosis

With contractor assistance, test pits were placed at the exterior of the building to determine if the impact damaged or displaced the foundation. Additionally, sections of the interior ceiling were removed to observe existing conditions and confirm if the roof framing was damaged. Upon review, the existing unreinforced CMU foundation and concrete sub-foundation did not appear to be damaged, nor did the existing roof framing, however the existing roof framing was not properly secured to the existing wall as several anchor bolts were not engaged. The full length of the West CMU wall was damaged, and part of the south wall was displaced.

 

 

 

Solution

Vital Structures prepared design documents to remove and replace the above grade portion of the full length of the West wall, and a section of the South wall with new reinforced CMU. In addition, new wood bracing and supplemental anchors were added to the roof framing to provide lateral stability for the new wall.
