Saltbox Condominiums, Quechee, VT

PERCH was hired by a realtor to inspect a condominium with a sagging floor in Quechee, VT. Climbing into a dark crawlspace below the unit, PERCH determined that the floor joists were inadequate and that a metal column providing interior support was crushing the wood beam above. PERCH developed a procedure to lift the floor to level with minimal disturbance to interior finishes. PERCH also designed two options for a permanent support system.

1 Londonderry Lane, Essex Junction, VT

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 contractor x to address constructability concerns and execute the revisions.
