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 the Eiffel factory in the nearby Parisian suburb of Levallois-Perret. The change in structural material from masonry to iron allowed Bartholdi to change his plans for the statue's assembly. He had originally expected to assemble the skin on-site as the masonry pier was built; instead he decided to build the statue in France and have it disassembled and transported to the United States for reassembly in place on Bedloe's Island. In a symbolic act, the first rivet placed into the skin, fixing a copper plate onto the statue's big toe, was driven by United States Ambassador to France Levi P.
