Statue of Liberty pedestal was to have been made of solid granite. Financial concerns again forced him to revise his plans; the final design called for poured concrete walls, up to thick, faced with granite blocks. This Stony Creek granite came from the Beattie Quarry in Branford, Connecticut. The concrete mass was the largest poured to that time. Norwegian immigrant civil engineer Joachim Goschen Giæver designed the structural framework for the Statue of Liberty. His work involved design computations, detailed fabrication and construction drawings, and oversight of construction. In completing his engineering for the statue's frame, Giæver worked from drawings and sketches produced
Statue of Liberty classical contours and applied simplified modeling, reflecting the huge scale of the project and its solemn purpose. Bartholdi wrote of his technique: Bartholdi made alterations in the design as the project evolved. Bartholdi considered having Liberty hold a broken chain, but decided this would be too divisive in the days after the Civil War. The erected statue does stride over a broken chain, half-hidden by her robes and difficult to see from the ground. Bartholdi was initially uncertain of what to place in Liberty's left hand; he settled on a "tabula ansata", used to evoke the concept of law. Though
