Dana Farber at Chestnut Hill

PERCH designed a freestanding hoist for renovations to an outpatient cancer facility in Newton, MA. An external steel tower supports the 5-story hoist mast, with a stabilizing tieback to the building roof.

Capstone Morrisville

PERCH designed the foundation for a 12,000 square foot Headstart facility in Morrisville, VT. The general contractor was H.A. Manosh. Custom roof trusses placed all loadbearing walls on the exterior, permitting a slab on grade with several construction joints on the interior. PERCH ordered soil testing and determined that the fill on site is non-frost-susceptible, enabling a shallow foundation around the perimeter of the exterior wall. PERCH prepared structural plans as needed for permitting and construction.

Kingsbury Construction

PERCH evaluated three existing roof structures for excess load carrying capacity to accommodate a 250 kW solar array at the headquarters of a construction company in Waitsfield, VT. Working on behalf of local solar furnisher Aegis Renewable Energy, PERCH analyzed roof purlins, beams, a header beam, perimeter support columns, and connections for adequacy. For components that did not meet requirements, PERCH designed and drafted details to strengthen the components including stronger bolted splice plates for the roof beams.
