PERCH inspected an accessory dwelling under construction in Essex Junction, VT. The homeowner expressed concern about the foundation and several other support systems. PERCH determined that the first floor carrying beams were inadequate to support a cantilevered portion of the floor, and designed several revisions including additional concrete piers and stronger beams. PERCH also inspected the foundation of the existing house via an extremely confined crawlspace, and recommended minimizing the ledger load on the existing foundation from the connected new building. PERCH worked closely with Bedard Construction to address constructability concerns and execute the revisions.
