Clippership Wharf

PERCH designed the foundation and support structure for a 90 foot tall tower crane used to build a new residential tower in East Boston. The crane was located on a floor slab above an open basement, requiring PERI shoring posts and a steel bridge beam assembly to transfer loads from the crane outrigger cones to four existing pile caps. PERCH also developed a construction sequence to pre-load the shoring posts and minimize deflection of the slab.
